-# How to become a contributor and submit your own code
-
-## Contributor License Agreements
-
-We'd love to accept your patches! Before we can take them, we have to jump a
-couple of legal hurdles.
-
-Please fill out either the individual or corporate Contributor License Agreement
-(CLA).
-
-*   If you are an individual writing original source code and you're sure you
-    own the intellectual property, then you'll need to sign an
-    [individual CLA](https://developers.google.com/open-source/cla/individual).
-*   If you work for a company that wants to allow you to contribute your work,
-    then you'll need to sign a
-    [corporate CLA](https://developers.google.com/open-source/cla/corporate).
-
-Follow either of the two links above to access the appropriate CLA and
-instructions for how to sign and return it. Once we receive it, we'll be able to
-accept your pull requests.
-
-## Are you a Googler?
-
-If you are a Googler, please make an attempt to submit an internal change rather
-than a GitHub Pull Request. If you are not able to submit an internal change a
-PR is acceptable as an alternative.
-
-## Contributing A Patch
-
-1.  Submit an issue describing your proposed change to the
-    [issue tracker](https://github.com/google/googletest).
-2.  Please don't mix more than one logical change per submittal, because it
-    makes the history hard to follow. If you want to make a change that doesn't
-    have a corresponding issue in the issue tracker, please create one.
-3.  Also, coordinate with team members that are listed on the issue in question.
-    This ensures that work isn't being duplicated and communicating your plan
-    early also generally leads to better patches.
-4.  If your proposed change is accepted, and you haven't already done so, sign a
-    Contributor License Agreement (see details above).
-5.  Fork the desired repo, develop and test your code changes.
-6.  Ensure that your code adheres to the existing style in the sample to which
-    you are contributing.
-7.  Ensure that your code has an appropriate set of unit tests which all pass.
-8.  Submit a pull request.
-
-## The Google Test and Google Mock Communities
-
-The Google Test community exists primarily through the
-[discussion group](http://groups.google.com/group/googletestframework) and the
-GitHub repository. Likewise, the Google Mock community exists primarily through
-their own [discussion group](http://groups.google.com/group/googlemock). You are
-definitely encouraged to contribute to the discussion and you can also help us
-to keep the effectiveness of the group high by following and promoting the
-guidelines listed here.
-
-### Please Be Friendly
-
-Showing courtesy and respect to others is a vital part of the Google culture,
-and we strongly encourage everyone participating in Google Test development to
-join us in accepting nothing less. Of course, being courteous is not the same as
-failing to constructively disagree with each other, but it does mean that we
-should be respectful of each other when enumerating the 42 technical reasons
-that a particular proposal may not be the best choice. There's never a reason to
-be antagonistic or dismissive toward anyone who is sincerely trying to
-contribute to a discussion.
-
-Sure, C++ testing is serious business and all that, but it's also a lot of fun.
-Let's keep it that way. Let's strive to be one of the friendliest communities in
-all of open source.
-
-As always, discuss Google Test in the official GoogleTest discussion group. You
-don't have to actually submit code in order to sign up. Your participation
-itself is a valuable contribution.
-
-## Style
-
-To keep the source consistent, readable, diffable and easy to merge, we use a
-fairly rigid coding style, as defined by the
-[google-styleguide](https://github.com/google/styleguide) project. All patches
-will be expected to conform to the style outlined
-[here](https://google.github.io/styleguide/cppguide.html). Use
-[.clang-format](https://github.com/google/googletest/blob/master/.clang-format)
-to check your formatting
-
-## Requirements for Contributors
-
-If you plan to contribute a patch, you need to build Google Test, Google Mock,
-and their own tests from a git checkout, which has further requirements:
-
-*   [Python](https://www.python.org/) v2.3 or newer (for running some of the
-    tests and re-generating certain source files from templates)
-*   [CMake](https://cmake.org/) v2.6.4 or newer
-
-## Developing Google Test and Google Mock
-
-This section discusses how to make your own changes to the Google Test project.
-
-### Testing Google Test and Google Mock Themselves
-
-To make sure your changes work as intended and don't break existing
-functionality, you'll want to compile and run Google Test and GoogleMock's own
-tests. For that you can use CMake:
-
-    mkdir mybuild
-    cd mybuild
-    cmake -Dgtest_build_tests=ON -Dgmock_build_tests=ON ${GTEST_REPO_DIR}
-
-To choose between building only Google Test or Google Mock, you may modify your
-cmake command to be one of each
-
-    cmake -Dgtest_build_tests=ON ${GTEST_DIR} # sets up Google Test tests
-    cmake -Dgmock_build_tests=ON ${GMOCK_DIR} # sets up Google Mock tests
-
-Make sure you have Python installed, as some of Google Test's tests are written
-in Python. If the cmake command complains about not being able to find Python
-(`Could NOT find PythonInterp (missing: PYTHON_EXECUTABLE)`), try telling it
-explicitly where your Python executable can be found:
-
-    cmake -DPYTHON_EXECUTABLE=path/to/python ...
-
-Next, you can build Google Test and / or Google Mock and all desired tests. On
-\*nix, this is usually done by
-
-    make
-
-To run the tests, do
-
-    make test
-
-All tests should pass.
-
-### Regenerating Source Files
-
-Some of Google Test's source files are generated from templates (not in the C++
-sense) using a script. For example, the file
-include/gtest/internal/gtest-type-util.h.pump is used to generate
-gtest-type-util.h in the same directory.
-
-You don't need to worry about regenerating the source files unless you need to
-modify them. You would then modify the corresponding `.pump` files and run the
-'[pump.py](googletest/scripts/pump.py)' generator script. See the
-[Pump Manual](googletest/docs/pump_manual.md).

-#### OSS Builds Status:
-
-[![Build Status](https://api.travis-ci.org/google/googletest.svg?branch=master)](https://travis-ci.org/google/googletest)
-[![Build status](https://ci.appveyor.com/api/projects/status/4o38plt0xbo1ubc8/branch/master?svg=true)](https://ci.appveyor.com/project/GoogleTestAppVeyor/googletest/branch/master)
-
-### Future Plans
-
-#### 1.8.x Release:
-
-[the 1.8.x](https://github.com/google/googletest/releases/tag/release-1.8.1) is
-the last release that works with pre-C++11 compilers. The 1.8.x will not accept
-any requests for any new features and any bugfix requests will only be accepted
-if proven "critical"
-
-#### Post 1.8.x:
-
-On-going work to improve/cleanup/pay technical debt. When this work is completed
-there will be a 1.9.x tagged release
-
-#### Post 1.9.x
-
-Post 1.9.x googletest will follow

-
-## Welcome to **Google Test**, Google's C++ test framework!
-
-This repository is a merger of the formerly separate GoogleTest and GoogleMock
-projects. These were so closely related that it makes sense to maintain and
-release them together.
-
-Please subscribe to the mailing list at googletestframework@googlegroups.com for
-questions, discussions, and development.
-
-### Getting started:
-
-The information for **Google Test** is available in the
-[Google Test Primer](googletest/docs/primer.md) documentation.
-
-**Google Mock** is an extension to Google Test for writing and using C++ mock
-classes. See the separate [Google Mock documentation](googlemock/README.md).
-
-More detailed documentation for googletest is in its interior
-[googletest/README.md](googletest/README.md) file.
-
-## Features
-
-*   An [xUnit](https://en.wikipedia.org/wiki/XUnit) test framework.
-*   Test discovery.
-*   A rich set of assertions.
-*   User-defined assertions.
-*   Death tests.
-*   Fatal and non-fatal failures.
-*   Value-parameterized tests.
-*   Type-parameterized tests.
-*   Various options for running the tests.
-*   XML test report generation.
-
-## Platforms
-
-Google test has been used on a variety of platforms:
-
-*   Linux
-*   Mac OS X
-*   Windows
-*   Cygwin
-*   MinGW
-*   Windows Mobile
-*   Symbian
-*   PlatformIO
-
-## Who Is Using Google Test?
-
-In addition to many internal projects at Google, Google Test is also used by the
-following notable projects:
-
-*   The [Chromium projects](http://www.chromium.org/) (behind the Chrome browser
-    and Chrome OS).
-*   The [LLVM](http://llvm.org/) compiler.
-*   [Protocol Buffers](https://github.com/google/protobuf), Google's data
-    interchange format.
-*   The [OpenCV](http://opencv.org/) computer vision library.
-*   [tiny-dnn](https://github.com/tiny-dnn/tiny-dnn): header only,
-    dependency-free deep learning framework in C++11.
-
-## Related Open Source Projects
-
-[GTest Runner](https://github.com/nholthaus/gtest-runner) is a Qt5 based
-automated test-runner and Graphical User Interface with powerful features for
-Windows and Linux platforms.
-
-[Google Test UI](https://github.com/ospector/gtest-gbar) is test runner that
-runs your test binary, allows you to track its progress via a progress bar, and
-displays a list of test failures. Clicking on one shows failure text. Google
-Test UI is written in C#.
-
-[GTest TAP Listener](https://github.com/kinow/gtest-tap-listener) is an event
-listener for Google Test that implements the
-[TAP protocol](https://en.wikipedia.org/wiki/Test_Anything_Protocol) for test
-result output. If your test runner understands TAP, you may find it useful.
-
-[gtest-parallel](https://github.com/google/gtest-parallel) is a test runner that
-runs tests from your binary in parallel to provide significant speed-up.
-
-[GoogleTest Adapter](https://marketplace.visualstudio.com/items?itemName=DavidSchuldenfrei.gtest-adapter)
-is a VS Code extension allowing to view Google Tests in a tree view, and
-run/debug your tests.
-
-## Requirements
-
-Google Test is designed to have fairly minimal requirements to build and use
-with your projects, but there are some. If you notice any problems on your
-platform, please notify
-[googletestframework@googlegroups.com](https://groups.google.com/forum/#!forum/googletestframework).
-Patches for fixing them are welcome!
-
-### Build Requirements
-
-These are the base requirements to build and use Google Test from a source
-package:
-
-*   [Bazel](https://bazel.build/) or [CMake](https://cmake.org/). NOTE: Bazel is
-    the build system that googletest is using internally and tests against.
-    CMake is community-supported.
-
-*   a C++11-standard-compliant compiler
-
-## Contributing change
-
-Please read the [`CONTRIBUTING.md`](CONTRIBUTING.md) for details on how to
-contribute to this project.

-# Googletest Mocking (gMock) Framework
-
-### Overview
-
-Google's framework for writing and using C++ mock classes. It can help you
-derive better designs of your system and write better tests.
-
-It is inspired by:
-
-*   [jMock](http://www.jmock.org/),
-*   [EasyMock](http://www.easymock.org/), and
-*   [Hamcrest](http://code.google.com/p/hamcrest/),
-
-and designed with C++'s specifics in mind.
-
-gMock:
-
--   provides a declarative syntax for defining mocks,
--   can define partial (hybrid) mocks, which are a cross of real and mock
-    objects,
--   handles functions of arbitrary types and overloaded functions,
--   comes with a rich set of matchers for validating function arguments,
--   uses an intuitive syntax for controlling the behavior of a mock,
--   does automatic verification of expectations (no record-and-replay needed),
--   allows arbitrary (partial) ordering constraints on function calls to be
-    expressed,
--   lets a user extend it by defining new matchers and actions.
--   does not use exceptions, and
--   is easy to learn and use.
-
-Details and examples can be found here:
-
-*   [gMock for Dummies](docs/for_dummies.md)
-*   [Legacy gMock FAQ](docs/gmock_faq.md)
-*   [gMock Cookbook](docs/cook_book.md)
-*   [gMock Cheat Sheet](docs/cheat_sheet.md)
-
-Please note that code under scripts/generator/ is from the [cppclean
-project](http://code.google.com/p/cppclean/) and under the Apache
-License, which is different from Google Mock's license.
-
-Google Mock is a part of
-[Google Test C++ testing framework](http://github.com/google/googletest/) and a
-subject to the same requirements.

-### Defining a Mock Class
-
-#### Mocking a Normal Class {#MockClass}
-
-Given
-
-```cpp
-class Foo {
-  ...
-  virtual ~Foo();
-  virtual int GetSize() const = 0;
-  virtual string Describe(const char* name) = 0;
-  virtual string Describe(int type) = 0;
-  virtual bool Process(Bar elem, int count) = 0;
-};
-```
-
-(note that `~Foo()` **must** be virtual) we can define its mock as
-
-```cpp
-#include "gmock/gmock.h"
-
-class MockFoo : public Foo {
-  ...
-  MOCK_METHOD(int, GetSize, (), (const, override));
-  MOCK_METHOD(string, Describe, (const char* name), (override));
-  MOCK_METHOD(string, Describe, (int type), (override));
-  MOCK_METHOD(bool, Process, (Bar elem, int count), (override));
-};
-```
-
-To create a "nice" mock, which ignores all uninteresting calls, a "naggy" mock,
-which warns on all uninteresting calls, or a "strict" mock, which treats them as
-failures:
-
-```cpp
-using ::testing::NiceMock;
-using ::testing::NaggyMock;
-using ::testing::StrictMock;
-
-NiceMock<MockFoo> nice_foo;      // The type is a subclass of MockFoo.
-NaggyMock<MockFoo> naggy_foo;    // The type is a subclass of MockFoo.
-StrictMock<MockFoo> strict_foo;  // The type is a subclass of MockFoo.
-```
-
-**Note:** A mock object is currently naggy by default. We may make it nice by
-default in the future.
-
-#### Mocking a Class Template {#MockTemplate}
-
-Class templates can be mocked just like any class.
-
-To mock
-
-```cpp
-template <typename Elem>
-class StackInterface {
-  ...
-  virtual ~StackInterface();
-  virtual int GetSize() const = 0;
-  virtual void Push(const Elem& x) = 0;
-};
-```
-
-(note that all member functions that are mocked, including `~StackInterface()`
-**must** be virtual).
-
-```cpp
-template <typename Elem>
-class MockStack : public StackInterface<Elem> {
-  ...
-  MOCK_METHOD(int, GetSize, (), (const, override));
-  MOCK_METHOD(void, Push, (const Elem& x), (override));
-};
-```
-
-#### Specifying Calling Conventions for Mock Functions
-
-If your mock function doesn't use the default calling convention, you can
-specify it by adding `Calltype(convention)` to `MOCK_METHOD`'s 4th parameter.
-For example,
-
-```cpp
-  MOCK_METHOD(bool, Foo, (int n), (Calltype(STDMETHODCALLTYPE)));
-  MOCK_METHOD(int, Bar, (double x, double y),
-              (const, Calltype(STDMETHODCALLTYPE)));
-```
-
-where `STDMETHODCALLTYPE` is defined by `<objbase.h>` on Windows.
-
-### Using Mocks in Tests {#UsingMocks}
-
-The typical work flow is:
-
-1.  Import the gMock names you need to use. All gMock symbols are in the
-    `testing` namespace unless they are macros or otherwise noted.
-2.  Create the mock objects.
-3.  Optionally, set the default actions of the mock objects.
-4.  Set your expectations on the mock objects (How will they be called? What
-    will they do?).
-5.  Exercise code that uses the mock objects; if necessary, check the result
-    using googletest assertions.
-6.  When a mock object is destructed, gMock automatically verifies that all
-    expectations on it have been satisfied.
-
-Here's an example:
-
-```cpp
-using ::testing::Return;                          // #1
-
-TEST(BarTest, DoesThis) {
-  MockFoo foo;                                    // #2
-
-  ON_CALL(foo, GetSize())                         // #3
-      .WillByDefault(Return(1));
-  // ... other default actions ...
-
-  EXPECT_CALL(foo, Describe(5))                   // #4
-      .Times(3)
-      .WillRepeatedly(Return("Category 5"));
-  // ... other expectations ...
-
-  EXPECT_EQ("good", MyProductionFunction(&foo));  // #5
-}                                                 // #6
-```
-
-### Setting Default Actions {#OnCall}
-
-gMock has a **built-in default action** for any function that returns `void`,
-`bool`, a numeric value, or a pointer. In C++11, it will additionally returns
-the default-constructed value, if one exists for the given type.
-
-To customize the default action for functions with return type *`T`*:
-
-```cpp
-using ::testing::DefaultValue;
-
-// Sets the default value to be returned. T must be CopyConstructible.
-DefaultValue<T>::Set(value);
-// Sets a factory. Will be invoked on demand. T must be MoveConstructible.
-//  T MakeT();
-DefaultValue<T>::SetFactory(&MakeT);
-// ... use the mocks ...
-// Resets the default value.
-DefaultValue<T>::Clear();
-```
-
-Example usage:
-
-```cpp
-  // Sets the default action for return type std::unique_ptr<Buzz> to
-  // creating a new Buzz every time.
-  DefaultValue<std::unique_ptr<Buzz>>::SetFactory(
-      [] { return MakeUnique<Buzz>(AccessLevel::kInternal); });
-
-  // When this fires, the default action of MakeBuzz() will run, which
-  // will return a new Buzz object.
-  EXPECT_CALL(mock_buzzer_, MakeBuzz("hello")).Times(AnyNumber());
-
-  auto buzz1 = mock_buzzer_.MakeBuzz("hello");
-  auto buzz2 = mock_buzzer_.MakeBuzz("hello");
-  EXPECT_NE(nullptr, buzz1);
-  EXPECT_NE(nullptr, buzz2);
-  EXPECT_NE(buzz1, buzz2);
-
-  // Resets the default action for return type std::unique_ptr<Buzz>,
-  // to avoid interfere with other tests.
-  DefaultValue<std::unique_ptr<Buzz>>::Clear();
-```
-
-To customize the default action for a particular method of a specific mock
-object, use `ON_CALL()`. `ON_CALL()` has a similar syntax to `EXPECT_CALL()`,
-but it is used for setting default behaviors (when you do not require that the
-mock method is called). See [here](cook_book.md#UseOnCall) for a more detailed
-discussion.
-
-```cpp
-ON_CALL(mock-object, method(matchers))
-    .With(multi-argument-matcher)   ?
-    .WillByDefault(action);
-```
-
-### Setting Expectations {#ExpectCall}
-
-`EXPECT_CALL()` sets **expectations** on a mock method (How will it be called?
-What will it do?):
-
-```cpp
-EXPECT_CALL(mock-object, method (matchers)?)
-     .With(multi-argument-matcher)  ?
-     .Times(cardinality)            ?
-     .InSequence(sequences)         *
-     .After(expectations)           *
-     .WillOnce(action)              *
-     .WillRepeatedly(action)        ?
-     .RetiresOnSaturation();        ?
-```
-
-For each item above, `?` means it can be used at most once, while `*` means it
-can be used any number of times.
-
-In order to pass, `EXPECT_CALL` must be used before the calls are actually made.
-
-The `(matchers)` is a comma-separated list of matchers that correspond to each
-of the arguments of `method`, and sets the expectation only for calls of
-`method` that matches all of the matchers.
-
-If `(matchers)` is omitted, the expectation is the same as if the matchers were
-set to anything matchers (for example, `(_, _, _, _)` for a four-arg method).
-
-If `Times()` is omitted, the cardinality is assumed to be:
-
-*   `Times(1)` when there is neither `WillOnce()` nor `WillRepeatedly()`;
-*   `Times(n)` when there are `n` `WillOnce()`s but no `WillRepeatedly()`, where
-    `n` >= 1; or
-*   `Times(AtLeast(n))` when there are `n` `WillOnce()`s and a
-    `WillRepeatedly()`, where `n` >= 0.
-
-A method with no `EXPECT_CALL()` is free to be invoked *any number of times*,
-and the default action will be taken each time.
-
-### Matchers {#MatcherList}
-
-<!-- GOOGLETEST_CM0020 DO NOT DELETE -->
-
-A **matcher** matches a *single* argument. You can use it inside `ON_CALL()` or
-`EXPECT_CALL()`, or use it to validate a value directly using two macros:
-
-<!-- mdformat off(github rendering does not support multiline tables) -->
-| Macro                                | Description                           |
-| :----------------------------------- | :------------------------------------ |
-| `EXPECT_THAT(actual_value, matcher)` | Asserts that `actual_value` matches `matcher`. |
-| `ASSERT_THAT(actual_value, matcher)` | The same as `EXPECT_THAT(actual_value, matcher)`, except that it generates a **fatal** failure. |
-<!-- mdformat on -->
-
-Built-in matchers (where `argument` is the function argument, e.g.
-`actual_value` in the example above, or when used in the context of
-`EXPECT_CALL(mock_object, method(matchers))`, the arguments of `method`) are
-divided into several categories:
-
-#### Wildcard
-
-Matcher                     | Description
-:-------------------------- | :-----------------------------------------------
-`_`                         | `argument` can be any value of the correct type.
-`A<type>()` or `An<type>()` | `argument` can be any value of type `type`.
-
-#### Generic Comparison
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                | Description                                         |
-| :--------------------- | :-------------------------------------------------- |
-| `Eq(value)` or `value` | `argument == value`                                 |
-| `Ge(value)`            | `argument >= value`                                 |
-| `Gt(value)`            | `argument > value`                                  |
-| `Le(value)`            | `argument <= value`                                 |
-| `Lt(value)`            | `argument < value`                                  |
-| `Ne(value)`            | `argument != value`                                 |
-| `IsFalse()`            | `argument` evaluates to `false` in a Boolean context. |
-| `IsTrue()`             | `argument` evaluates to `true` in a Boolean context. |
-| `IsNull()`             | `argument` is a `NULL` pointer (raw or smart).      |
-| `NotNull()`            | `argument` is a non-null pointer (raw or smart).    |
-| `Optional(m)`          | `argument` is `optional<>` that contains a value matching `m`. |
-| `VariantWith<T>(m)`    | `argument` is `variant<>` that holds the alternative of type T with a value matching `m`. |
-| `Ref(variable)`        | `argument` is a reference to `variable`.            |
-| `TypedEq<type>(value)` | `argument` has type `type` and is equal to `value`. You may need to use this instead of `Eq(value)` when the mock function is overloaded. |
-<!-- mdformat on -->
-
-Except `Ref()`, these matchers make a *copy* of `value` in case it's modified or
-destructed later. If the compiler complains that `value` doesn't have a public
-copy constructor, try wrap it in `ByRef()`, e.g.
-`Eq(ByRef(non_copyable_value))`. If you do that, make sure `non_copyable_value`
-is not changed afterwards, or the meaning of your matcher will be changed.
-
-#### Floating-Point Matchers {#FpMatchers}
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                          | Description                        |
-| :------------------------------- | :--------------------------------- |
-| `DoubleEq(a_double)`             | `argument` is a `double` value approximately equal to `a_double`, treating two NaNs as unequal. |
-| `FloatEq(a_float)`               | `argument` is a `float` value approximately equal to `a_float`, treating two NaNs as unequal. |
-| `NanSensitiveDoubleEq(a_double)` | `argument` is a `double` value approximately equal to `a_double`, treating two NaNs as equal. |
-| `NanSensitiveFloatEq(a_float)`   | `argument` is a `float` value approximately equal to `a_float`, treating two NaNs as equal. |
-<!-- mdformat on -->
-
-The above matchers use ULP-based comparison (the same as used in googletest).
-They automatically pick a reasonable error bound based on the absolute value of
-the expected value. `DoubleEq()` and `FloatEq()` conform to the IEEE standard,
-which requires comparing two NaNs for equality to return false. The
-`NanSensitive*` version instead treats two NaNs as equal, which is often what a
-user wants.
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                                           | Description              |
-| :------------------------------------------------ | :----------------------- |
-| `DoubleNear(a_double, max_abs_error)`             | `argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
-| `FloatNear(a_float, max_abs_error)`               | `argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
-| `NanSensitiveDoubleNear(a_double, max_abs_error)` | `argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
-| `NanSensitiveFloatNear(a_float, max_abs_error)`   | `argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
-<!-- mdformat on -->
-
-#### String Matchers
-
-The `argument` can be either a C string or a C++ string object:
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                 | Description                                        |
-| :---------------------- | :------------------------------------------------- |
-| `ContainsRegex(string)` | `argument` matches the given regular expression.   |
-| `EndsWith(suffix)`      | `argument` ends with string `suffix`.              |
-| `HasSubstr(string)`     | `argument` contains `string` as a sub-string.      |
-| `MatchesRegex(string)`  | `argument` matches the given regular expression with the match starting at the first character and ending at the last character. |
-| `StartsWith(prefix)`    | `argument` starts with string `prefix`.            |
-| `StrCaseEq(string)`     | `argument` is equal to `string`, ignoring case.    |
-| `StrCaseNe(string)`     | `argument` is not equal to `string`, ignoring case. |
-| `StrEq(string)`         | `argument` is equal to `string`.                   |
-| `StrNe(string)`         | `argument` is not equal to `string`.               |
-<!-- mdformat on -->
-
-`ContainsRegex()` and `MatchesRegex()` take ownership of the `RE` object. They
-use the regular expression syntax defined
-[here](../../googletest/docs/advanced.md#regular-expression-syntax).
-`StrCaseEq()`, `StrCaseNe()`, `StrEq()`, and `StrNe()` work for wide strings as
-well.
-
-#### Container Matchers
-
-Most STL-style containers support `==`, so you can use `Eq(expected_container)`
-or simply `expected_container` to match a container exactly. If you want to
-write the elements in-line, match them more flexibly, or get more informative
-messages, you can use:
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                                   | Description                      |
-| :---------------------------------------- | :------------------------------- |
-| `BeginEndDistanceIs(m)` | `argument` is a container whose `begin()` and `end()` iterators are separated by a number of increments matching `m`. E.g. `BeginEndDistanceIs(2)` or `BeginEndDistanceIs(Lt(2))`. For containers that define a `size()` method, `SizeIs(m)` may be more efficient. |
-| `ContainerEq(container)` | The same as `Eq(container)` except that the failure message also includes which elements are in one container but not the other. |
-| `Contains(e)` | `argument` contains an element that matches `e`, which can be either a value or a matcher. |
-| `Each(e)` | `argument` is a container where *every* element matches `e`, which can be either a value or a matcher. |
-| `ElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, where the *i*-th element matches `ei`, which can be a value or a matcher. |
-| `ElementsAreArray({e0, e1, ..., en})`, `ElementsAreArray(a_container)`, `ElementsAreArray(begin, end)`, `ElementsAreArray(array)`, or `ElementsAreArray(array, count)` | The same as `ElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
-| `IsEmpty()` | `argument` is an empty container (`container.empty()`). |
-| `IsSubsetOf({e0, e1, ..., en})`, `IsSubsetOf(a_container)`, `IsSubsetOf(begin, end)`, `IsSubsetOf(array)`, or `IsSubsetOf(array, count)` | `argument` matches `UnorderedElementsAre(x0, x1, ..., xk)` for some subset `{x0, x1, ..., xk}` of the expected matchers. |
-| `IsSupersetOf({e0, e1, ..., en})`, `IsSupersetOf(a_container)`, `IsSupersetOf(begin, end)`, `IsSupersetOf(array)`, or `IsSupersetOf(array, count)` | Some subset of `argument` matches `UnorderedElementsAre(`expected matchers`)`. |
-| `Pointwise(m, container)`, `Pointwise(m, {e0, e1, ..., en})` | `argument` contains the same number of elements as in `container`, and for all i, (the i-th element in `argument`, the i-th element in `container`) match `m`, which is a matcher on 2-tuples. E.g. `Pointwise(Le(), upper_bounds)` verifies that each element in `argument` doesn't exceed the corresponding element in `upper_bounds`. See more detail below. |
-| `SizeIs(m)` | `argument` is a container whose size matches `m`. E.g. `SizeIs(2)` or `SizeIs(Lt(2))`. |
-| `UnorderedElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, and under *some* permutation of the elements, each element matches an `ei` (for a different `i`), which can be a value or a matcher. |
-| `UnorderedElementsAreArray({e0, e1, ..., en})`, `UnorderedElementsAreArray(a_container)`, `UnorderedElementsAreArray(begin, end)`, `UnorderedElementsAreArray(array)`, or `UnorderedElementsAreArray(array, count)` | The same as `UnorderedElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
-| `UnorderedPointwise(m, container)`, `UnorderedPointwise(m, {e0, e1, ..., en})` | Like `Pointwise(m, container)`, but ignores the order of elements. |
-| `WhenSorted(m)` | When `argument` is sorted using the `<` operator, it matches container matcher `m`. E.g. `WhenSorted(ElementsAre(1, 2, 3))` verifies that `argument` contains elements 1, 2, and 3, ignoring order. |
-| `WhenSortedBy(comparator, m)` | The same as `WhenSorted(m)`, except that the given comparator instead of `<` is used to sort `argument`. E.g. `WhenSortedBy(std::greater(), ElementsAre(3, 2, 1))`. |

-**Notes:**
-
-*   These matchers can also match:
-    1.  a native array passed by reference (e.g. in `Foo(const int (&a)[5])`),
-        and
-    2.  an array passed as a pointer and a count (e.g. in `Bar(const T* buffer,
-        int len)` -- see [Multi-argument Matchers](#MultiArgMatchers)).
-*   The array being matched may be multi-dimensional (i.e. its elements can be
-    arrays).
-*   `m` in `Pointwise(m, ...)` should be a matcher for `::std::tuple<T, U>`
-    where `T` and `U` are the element type of the actual container and the
-    expected container, respectively. For example, to compare two `Foo`
-    containers where `Foo` doesn't support `operator==`, one might write:
-
-    ```cpp
-    using ::std::get;
-    MATCHER(FooEq, "") {
-      return std::get<0>(arg).Equals(std::get<1>(arg));
-    }
-    ...
-    EXPECT_THAT(actual_foos, Pointwise(FooEq(), expected_foos));
-    ```

-| :------------------------------ | :----------------------------------------- |
-| `Field(&class::field, m)`       | `argument.field` (or `argument->field` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_. |
-| `Key(e)`                        | `argument.first` matches `e`, which can be either a value or a matcher. E.g. `Contains(Key(Le(5)))` can verify that a `map` contains a key `<= 5`. |
-| `Pair(m1, m2)`                  | `argument` is an `std::pair` whose `first` field matches `m1` and `second` field matches `m2`. |
-| `Property(&class::property, m)` | `argument.property()` (or `argument->property()` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_. |

-#### Multi-argument Matchers {#MultiArgMatchers}
-
-Technically, all matchers match a *single* value. A "multi-argument" matcher is
-just one that matches a *tuple*. The following matchers can be used to match a
-tuple `(x, y)`:
-
-Matcher | Description
-:------ | :----------
-`Eq()`  | `x == y`
-`Ge()`  | `x >= y`
-`Gt()`  | `x > y`
-`Le()`  | `x <= y`
-`Lt()`  | `x < y`
-`Ne()`  | `x != y`
-
-You can use the following selectors to pick a subset of the arguments (or
-reorder them) to participate in the matching:
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                    | Description                                     |
-| :------------------------- | :---------------------------------------------- |
-| `AllArgs(m)`               | Equivalent to `m`. Useful as syntactic sugar in `.With(AllArgs(m))`. |
-| `Args<N1, N2, ..., Nk>(m)` | The tuple of the `k` selected (using 0-based indices) arguments matches `m`, e.g. `Args<1, 2>(Eq())`. |
-<!-- mdformat on -->
-
-#### Composite Matchers
-
-You can make a matcher from one or more other matchers:
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                          | Description                             |
-| :------------------------------- | :-------------------------------------- |
-| `AllOf(m1, m2, ..., mn)` | `argument` matches all of the matchers `m1` to `mn`. |
-| `AllOfArray({m0, m1, ..., mn})`, `AllOfArray(a_container)`, `AllOfArray(begin, end)`, `AllOfArray(array)`, or `AllOfArray(array, count)` | The same as `AllOf()` except that the matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
-| `AnyOf(m1, m2, ..., mn)` | `argument` matches at least one of the matchers `m1` to `mn`. |
-| `AnyOfArray({m0, m1, ..., mn})`, `AnyOfArray(a_container)`, `AnyOfArray(begin, end)`, `AnyOfArray(array)`, or `AnyOfArray(array, count)` | The same as `AnyOf()` except that the matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
-| `Not(m)` | `argument` doesn't match matcher `m`. |

-#### Adapters for Matchers
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                 | Description                           |
-| :---------------------- | :------------------------------------ |
-| `MatcherCast<T>(m)`     | casts matcher `m` to type `Matcher<T>`. |
-| `SafeMatcherCast<T>(m)` | [safely casts](cook_book.md#casting-matchers) matcher `m` to type `Matcher<T>`. |
-| `Truly(predicate)`      | `predicate(argument)` returns something considered by C++ to be true, where `predicate` is a function or functor. |
-<!-- mdformat on -->
-
-`AddressSatisfies(callback)` and `Truly(callback)` take ownership of `callback`,
-which must be a permanent callback.
-
-#### Using Matchers as Predicates {#MatchersAsPredicatesCheat}
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                       | Description                                 |
-| :---------------------------- | :------------------------------------------ |
-| `Matches(m)(value)` | evaluates to `true` if `value` matches `m`. You can use `Matches(m)` alone as a unary functor. |
-| `ExplainMatchResult(m, value, result_listener)` | evaluates to `true` if `value` matches `m`, explaining the result to `result_listener`. |
-| `Value(value, m)` | evaluates to `true` if `value` matches `m`. |
-<!-- mdformat on -->
-
-#### Defining Matchers
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                              | Description                           |
-| :----------------------------------- | :------------------------------------ |
-| `MATCHER(IsEven, "") { return (arg % 2) == 0; }` | Defines a matcher `IsEven()` to match an even number. |
-| `MATCHER_P(IsDivisibleBy, n, "") { *result_listener << "where the remainder is " << (arg % n); return (arg % n) == 0; }` | Defines a macher `IsDivisibleBy(n)` to match a number divisible by `n`. |
-| `MATCHER_P2(IsBetween, a, b, std::string(negation ? "isn't" : "is") + " between " + PrintToString(a) + " and " + PrintToString(b)) { return a <= arg && arg <= b; }` | Defines a matcher `IsBetween(a, b)` to match a value in the range [`a`, `b`]. |
-<!-- mdformat on -->
-
-**Notes:**
-
-1.  The `MATCHER*` macros cannot be used inside a function or class.
-2.  The matcher body must be *purely functional* (i.e. it cannot have any side
-    effect, and the result must not depend on anything other than the value
-    being matched and the matcher parameters).
-3.  You can use `PrintToString(x)` to convert a value `x` of any type to a
-    string.
-
-### Actions {#ActionList}
-
-**Actions** specify what a mock function should do when invoked.
-
-#### Returning a Value
-
-<!-- mdformat off(no multiline tables) -->
-|                             |                                               |
-| :-------------------------- | :-------------------------------------------- |
-| `Return()`                  | Return from a `void` mock function.           |
-| `Return(value)`             | Return `value`. If the type of `value` is     different to the mock function's return type, `value` is converted to the latter type <i>at the time the expectation is set</i>, not when the action is executed. |
-| `ReturnArg<N>()`            | Return the `N`-th (0-based) argument.         |
-| `ReturnNew<T>(a1, ..., ak)` | Return `new T(a1, ..., ak)`; a different      object is created each time. |
-| `ReturnNull()`              | Return a null pointer.                        |
-| `ReturnPointee(ptr)`        | Return the value pointed to by `ptr`.         |
-| `ReturnRef(variable)`       | Return a reference to `variable`.             |
-| `ReturnRefOfCopy(value)`    | Return a reference to a copy of `value`; the  copy lives as long as the action. |
-<!-- mdformat on -->
-
-#### Side Effects
-
-<!-- mdformat off(no multiline tables) -->
-|                                    |                                         |
-| :--------------------------------- | :-------------------------------------- |
-| `Assign(&variable, value)` | Assign `value` to variable. |
-| `DeleteArg<N>()` | Delete the `N`-th (0-based) argument, which must be a pointer. |
-| `SaveArg<N>(pointer)` | Save the `N`-th (0-based) argument to `*pointer`. |
-| `SaveArgPointee<N>(pointer)` | Save the value pointed to by the `N`-th (0-based) argument to `*pointer`. |
-| `SetArgReferee<N>(value)` | Assign value to the variable referenced by the `N`-th (0-based) argument. |
-| `SetArgPointee<N>(value)` | Assign `value` to the variable pointed by the `N`-th (0-based) argument. |
-| `SetArgumentPointee<N>(value)` | Same as `SetArgPointee<N>(value)`. Deprecated. Will be removed in v1.7.0. |
-| `SetArrayArgument<N>(first, last)` | Copies the elements in source range [`first`, `last`) to the array pointed to by the `N`-th (0-based) argument, which can be either a pointer or an iterator. The action does not take ownership of the elements in the source range. |
-| `SetErrnoAndReturn(error, value)` | Set `errno` to `error` and return `value`. |
-| `Throw(exception)` | Throws the given exception, which can be any copyable value. Available since v1.1.0. |
-<!-- mdformat on -->
-
-#### Using a Function, Functor, or Lambda as an Action
-
-In the following, by "callable" we mean a free function, `std::function`,
-functor, or lambda.
-
-<!-- mdformat off(no multiline tables) -->
-|                                     |                                        |
-| :---------------------------------- | :------------------------------------- |
-| `f` | Invoke f with the arguments passed to the mock function, where f is a callable. |
-| `Invoke(f)` | Invoke `f` with the arguments passed to the mock function, where `f` can be a global/static function or a functor. |
-| `Invoke(object_pointer, &class::method)` | Invoke the method on the object with the arguments passed to the mock function. |
-| `InvokeWithoutArgs(f)` | Invoke `f`, which can be a global/static function or a functor. `f` must take no arguments. |
-| `InvokeWithoutArgs(object_pointer, &class::method)` | Invoke the method on the object, which takes no arguments. |
-| `InvokeArgument<N>(arg1, arg2, ..., argk)` | Invoke the mock function's `N`-th (0-based) argument, which must be a function or a functor, with the `k` arguments. |
-<!-- mdformat on -->
-
-The return value of the invoked function is used as the return value of the
-action.
-
-When defining a callable to be used with `Invoke*()`, you can declare any unused
-parameters as `Unused`:
-
-```cpp
-using ::testing::Invoke;
-double Distance(Unused, double x, double y) { return sqrt(x*x + y*y); }
-...
-EXPECT_CALL(mock, Foo("Hi", _, _)).WillOnce(Invoke(Distance));
-```
-
-`Invoke(callback)` and `InvokeWithoutArgs(callback)` take ownership of
-`callback`, which must be permanent. The type of `callback` must be a base
-callback type instead of a derived one, e.g.
-
-```cpp
-  BlockingClosure* done = new BlockingClosure;
-  ... Invoke(done) ...;  // This won't compile!
-
-  Closure* done2 = new BlockingClosure;
-  ... Invoke(done2) ...;  // This works.
-```
-
-In `InvokeArgument<N>(...)`, if an argument needs to be passed by reference,
-wrap it inside `ByRef()`. For example,
-
-```cpp
-using ::testing::ByRef;
-using ::testing::InvokeArgument;
-...
-InvokeArgument<2>(5, string("Hi"), ByRef(foo))
-```
-
-calls the mock function's #2 argument, passing to it `5` and `string("Hi")` by
-value, and `foo` by reference.
-
-#### Default Action
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher       | Description                                            |
-| :------------ | :----------------------------------------------------- |
-| `DoDefault()` | Do the default action (specified by `ON_CALL()` or the built-in one). |
-<!-- mdformat on -->
-
-**Note:** due to technical reasons, `DoDefault()` cannot be used inside a
-composite action - trying to do so will result in a run-time error.

-| :----------------------------- | :------------------------------------------ |
-| `DoAll(a1, a2, ..., an)`       | Do all actions `a1` to `an` and return the result of `an` in each invocation. The first `n - 1` sub-actions must return void. |
-| `IgnoreResult(a)`              | Perform action `a` and ignore its result. `a` must not return void. |
-| `WithArg<N>(a)`                | Pass the `N`-th (0-based) argument of the mock function to action `a` and perform it. |
-| `WithArgs<N1, N2, ..., Nk>(a)` | Pass the selected (0-based) arguments of the mock function to action `a` and perform it. |
-| `WithoutArgs(a)`               | Perform action `a` without any arguments. |

-| :--------------------------------- | :-------------------------------------- |
-| `ACTION(Sum) { return arg0 + arg1; }` | Defines an action `Sum()` to return the sum of the mock function's argument #0 and #1. |
-| `ACTION_P(Plus, n) { return arg0 + n; }` | Defines an action `Plus(n)` to return the sum of the mock function's argument #0 and `n`. |
-| `ACTION_Pk(Foo, p1, ..., pk) { statements; }` | Defines a parameterized action `Foo(p1, ..., pk)` to execute the given `statements`. |
-<!-- mdformat on -->
-
-The `ACTION*` macros cannot be used inside a function or class.
-
-### Cardinalities {#CardinalityList}
-
-These are used in `Times()` to specify how many times a mock function will be
-called:
-
-<!-- mdformat off(no multiline tables) -->
-|                   |                                                        |
-| :---------------- | :----------------------------------------------------- |
-| `AnyNumber()`     | The function can be called any number of times.        |
-| `AtLeast(n)`      | The call is expected at least `n` times.               |
-| `AtMost(n)`       | The call is expected at most `n` times.                |
-| `Between(m, n)`   | The call is expected between `m` and `n` (inclusive) times. |
-| `Exactly(n) or n` | The call is expected exactly `n` times. In particular, the call should never happen when `n` is 0. |
-<!-- mdformat on -->
-
-### Expectation Order
-
-By default, the expectations can be matched in *any* order. If some or all
-expectations must be matched in a given order, there are two ways to specify it.
-They can be used either independently or together.
-
-#### The After Clause {#AfterClause}
-
-```cpp
-using ::testing::Expectation;
-...
-Expectation init_x = EXPECT_CALL(foo, InitX());
-Expectation init_y = EXPECT_CALL(foo, InitY());
-EXPECT_CALL(foo, Bar())
-     .After(init_x, init_y);
-```
-
-says that `Bar()` can be called only after both `InitX()` and `InitY()` have
-been called.
-
-If you don't know how many pre-requisites an expectation has when you write it,
-you can use an `ExpectationSet` to collect them:
-
-```cpp
-using ::testing::ExpectationSet;
-...
-ExpectationSet all_inits;
-for (int i = 0; i < element_count; i++) {
-  all_inits += EXPECT_CALL(foo, InitElement(i));
-}
-EXPECT_CALL(foo, Bar())
-     .After(all_inits);
-```
-
-says that `Bar()` can be called only after all elements have been initialized
-(but we don't care about which elements get initialized before the others).
-
-Modifying an `ExpectationSet` after using it in an `.After()` doesn't affect the
-meaning of the `.After()`.
-
-#### Sequences {#UsingSequences}
-
-When you have a long chain of sequential expectations, it's easier to specify
-the order using **sequences**, which don't require you to given each expectation
-in the chain a different name. *All expected calls* in the same sequence must
-occur in the order they are specified.
-
-```cpp
-using ::testing::Return;
-using ::testing::Sequence;
-Sequence s1, s2;
-...
-EXPECT_CALL(foo, Reset())
-    .InSequence(s1, s2)
-    .WillOnce(Return(true));
-EXPECT_CALL(foo, GetSize())
-    .InSequence(s1)
-    .WillOnce(Return(1));
-EXPECT_CALL(foo, Describe(A<const char*>()))
-    .InSequence(s2)
-    .WillOnce(Return("dummy"));
-```
-
-says that `Reset()` must be called before *both* `GetSize()` *and* `Describe()`,
-and the latter two can occur in any order.
-
-To put many expectations in a sequence conveniently:
-
-```cpp
-using ::testing::InSequence;
-{
-  InSequence seq;
-
-  EXPECT_CALL(...)...;
-  EXPECT_CALL(...)...;
-  ...
-  EXPECT_CALL(...)...;
-}
-```
-
-says that all expected calls in the scope of `seq` must occur in strict order.
-The name `seq` is irrelevant.
-
-### Verifying and Resetting a Mock
-
-gMock will verify the expectations on a mock object when it is destructed, or
-you can do it earlier:
-
-```cpp
-using ::testing::Mock;
-...
-// Verifies and removes the expectations on mock_obj;
-// returns true if and only if successful.
-Mock::VerifyAndClearExpectations(&mock_obj);
-...
-// Verifies and removes the expectations on mock_obj;
-// also removes the default actions set by ON_CALL();
-// returns true if and only if successful.
-Mock::VerifyAndClear(&mock_obj);
-```
-
-You can also tell gMock that a mock object can be leaked and doesn't need to be
-verified:
-
-```cpp
-Mock::AllowLeak(&mock_obj);
-```
-
-### Mock Classes
-
-gMock defines a convenient mock class template
-
-```cpp
-class MockFunction<R(A1, ..., An)> {
- public:
-  MOCK_METHOD(R, Call, (A1, ..., An));
-};
-```
-
-See this [recipe](cook_book.md#using-check-points) for one application of it.
-
-### Flags

-## Creating Mock Classes
-
-Mock classes are defined as normal classes, using the `MOCK_METHOD` macro to
-generate mocked methods. The macro gets 3 or 4 parameters:
-
-```cpp
-class MyMock {
- public:
-  MOCK_METHOD(ReturnType, MethodName, (Args...));
-  MOCK_METHOD(ReturnType, MethodName, (Args...), (Specs...));
-};
-```
-
-The first 3 parameters are simply the method declaration, split into 3 parts.
-The 4th parameter accepts a closed list of qualifiers, which affect the
-generated method:
-
-*   **`const`** - Makes the mocked method a `const` method. Required if
-    overriding a `const` method.
-*   **`override`** - Marks the method with `override`. Recommended if overriding
-    a `virtual` method.
-*   **`noexcept`** - Marks the method with `noexcept`. Required if overriding a
-    `noexcept` method.
-*   **`Calltype(...)`** - Sets the call type for the method (e.g. to
-    `STDMETHODCALLTYPE`), useful in Windows.
-
-### Dealing with unprotected commas
-
-Unprotected commas, i.e. commas which are not surrounded by parentheses, prevent
-`MOCK_METHOD` from parsing its arguments correctly:
-
-```cpp {.bad}
-class MockFoo {
- public:
-  MOCK_METHOD(std::pair<bool, int>, GetPair, ());  // Won't compile!
-  MOCK_METHOD(bool, CheckMap, (std::map<int, double>, bool));  // Won't compile!
-};
-```
-
-Solution 1 - wrap with parentheses:
-
-```cpp {.good}
-class MockFoo {
- public:
-  MOCK_METHOD((std::pair<bool, int>), GetPair, ());
-  MOCK_METHOD(bool, CheckMap, ((std::map<int, double>), bool));
-};
-```
-
-Note that wrapping a return or argument type with parentheses is, in general,
-invalid C++. `MOCK_METHOD` removes the parentheses.
-
-Solution 2 - define an alias:
-
-```cpp {.good}
-class MockFoo {
- public:
-  using BoolAndInt = std::pair<bool, int>;
-  MOCK_METHOD(BoolAndInt, GetPair, ());
-  using MapIntDouble = std::map<int, double>;
-  MOCK_METHOD(bool, CheckMap, (MapIntDouble, bool));
-};
-```
-
-### Mocking Private or Protected Methods
-
-You must always put a mock method definition (`MOCK_METHOD`) in a `public:`
-section of the mock class, regardless of the method being mocked being `public`,
-`protected`, or `private` in the base class. This allows `ON_CALL` and
-`EXPECT_CALL` to reference the mock function from outside of the mock class.
-(Yes, C++ allows a subclass to change the access level of a virtual function in
-the base class.) Example:
-
-```cpp
-class Foo {
- public:
-  ...
-  virtual bool Transform(Gadget* g) = 0;
-
- protected:
-  virtual void Resume();
-
- private:
-  virtual int GetTimeOut();
-};
-
-class MockFoo : public Foo {
- public:
-  ...
-  MOCK_METHOD(bool, Transform, (Gadget* g), (override));
-
-  // The following must be in the public section, even though the
-  // methods are protected or private in the base class.
-  MOCK_METHOD(void, Resume, (), (override));
-  MOCK_METHOD(int, GetTimeOut, (), (override));
-};
-```
-
-### Mocking Overloaded Methods
-
-You can mock overloaded functions as usual. No special attention is required:
-
-```cpp
-class Foo {
-  ...
-
-  // Must be virtual as we'll inherit from Foo.
-  virtual ~Foo();
-
-  // Overloaded on the types and/or numbers of arguments.
-  virtual int Add(Element x);
-  virtual int Add(int times, Element x);
-
-  // Overloaded on the const-ness of this object.
-  virtual Bar& GetBar();
-  virtual const Bar& GetBar() const;
-};
-
-class MockFoo : public Foo {
-  ...
-  MOCK_METHOD(int, Add, (Element x), (override));
-  MOCK_METHOD(int, Add, (int times, Element x), (override));
-
-  MOCK_METHOD(Bar&, GetBar, (), (override));
-  MOCK_METHOD(const Bar&, GetBar, (), (const, override));
-};
-```
-
-**Note:** if you don't mock all versions of the overloaded method, the compiler
-will give you a warning about some methods in the base class being hidden. To
-fix that, use `using` to bring them in scope:
-
-```cpp
-class MockFoo : public Foo {
-  ...
-  using Foo::Add;
-  MOCK_METHOD(int, Add, (Element x), (override));
-  // We don't want to mock int Add(int times, Element x);
-  ...
-};
-```
-
-### Mocking Class Templates
-
-You can mock class templates just like any class.
-
-```cpp
-template <typename Elem>
-class StackInterface {
-  ...
-  // Must be virtual as we'll inherit from StackInterface.
-  virtual ~StackInterface();
-
-  virtual int GetSize() const = 0;
-  virtual void Push(const Elem& x) = 0;
-};
-
-template <typename Elem>
-class MockStack : public StackInterface<Elem> {
-  ...
-  MOCK_METHOD(int, GetSize, (), (override));
-  MOCK_METHOD(void, Push, (const Elem& x), (override));
-};
-```
-
-### Mocking Non-virtual Methods {#MockingNonVirtualMethods}
-
-gMock can mock non-virtual functions to be used in Hi-perf dependency
-injection.<!-- GOOGLETEST_CM0017 DO NOT DELETE -->
-
-In this case, instead of sharing a common base class with the real class, your
-mock class will be *unrelated* to the real class, but contain methods with the
-same signatures. The syntax for mocking non-virtual methods is the *same* as
-mocking virtual methods (just don't add `override`):
-
-```cpp
-// A simple packet stream class.  None of its members is virtual.
-class ConcretePacketStream {
- public:
-  void AppendPacket(Packet* new_packet);
-  const Packet* GetPacket(size_t packet_number) const;
-  size_t NumberOfPackets() const;
-  ...
-};
-
-// A mock packet stream class.  It inherits from no other, but defines
-// GetPacket() and NumberOfPackets().
-class MockPacketStream {
- public:
-  MOCK_METHOD(const Packet*, GetPacket, (size_t packet_number), (const));
-  MOCK_METHOD(size_t, NumberOfPackets, (), (const));
-  ...
-};
-```
-
-Note that the mock class doesn't define `AppendPacket()`, unlike the real class.
-That's fine as long as the test doesn't need to call it.
-
-Next, you need a way to say that you want to use `ConcretePacketStream` in
-production code, and use `MockPacketStream` in tests. Since the functions are
-not virtual and the two classes are unrelated, you must specify your choice at
-*compile time* (as opposed to run time).
-
-One way to do it is to templatize your code that needs to use a packet stream.
-More specifically, you will give your code a template type argument for the type
-of the packet stream. In production, you will instantiate your template with
-`ConcretePacketStream` as the type argument. In tests, you will instantiate the
-same template with `MockPacketStream`. For example, you may write:
-
-```cpp
-template <class PacketStream>
-void CreateConnection(PacketStream* stream) { ... }
-
-template <class PacketStream>
-class PacketReader {
- public:
-  void ReadPackets(PacketStream* stream, size_t packet_num);
-};
-```
-
-Then you can use `CreateConnection<ConcretePacketStream>()` and
-`PacketReader<ConcretePacketStream>` in production code, and use
-`CreateConnection<MockPacketStream>()` and `PacketReader<MockPacketStream>` in
-tests.
-
-```cpp
-  MockPacketStream mock_stream;
-  EXPECT_CALL(mock_stream, ...)...;
-  .. set more expectations on mock_stream ...
-  PacketReader<MockPacketStream> reader(&mock_stream);
-  ... exercise reader ...
-```
-
-### Mocking Free Functions
-
-It's possible to use gMock to mock a free function (i.e. a C-style function or a
-static method). You just need to rewrite your code to use an interface (abstract
-class).
-
-Instead of calling a free function (say, `OpenFile`) directly, introduce an
-interface for it and have a concrete subclass that calls the free function:
-
-```cpp
-class FileInterface {
- public:
-  ...
-  virtual bool Open(const char* path, const char* mode) = 0;
-};
-
-class File : public FileInterface {
- public:
-  ...
-  virtual bool Open(const char* path, const char* mode) {
-     return OpenFile(path, mode);
-  }
-};
-```
-
-Your code should talk to `FileInterface` to open a file. Now it's easy to mock
-out the function.
-
-This may seem like a lot of hassle, but in practice you often have multiple
-related functions that you can put in the same interface, so the per-function
-syntactic overhead will be much lower.
-
-If you are concerned about the performance overhead incurred by virtual
-functions, and profiling confirms your concern, you can combine this with the
-recipe for [mocking non-virtual methods](#MockingNonVirtualMethods).
-
-### Old-Style `MOCK_METHODn` Macros
-
-Before the generic `MOCK_METHOD` macro was introduced, mocks where created using
-a family of macros collectively called `MOCK_METHODn`. These macros are still
-supported, though migration to the new `MOCK_METHOD` is recommended.
-
-The macros in the `MOCK_METHODn` family differ from `MOCK_METHOD`:
-
-*   The general structure is `MOCK_METHODn(MethodName, ReturnType(Args))`,
-    instead of `MOCK_METHOD(ReturnType, MethodName, (Args))`.
-*   The number `n` must equal the number of arguments.
-*   When mocking a const method, one must use `MOCK_CONST_METHODn`.
-*   When mocking a class template, the macro name must be suffixed with `_T`.
-*   In order to specify the call type, the macro name must be suffixed with
-    `_WITH_CALLTYPE`, and the call type is the first macro argument.
-
-Old macros and their new equivalents:

-### The Nice, the Strict, and the Naggy {#NiceStrictNaggy}
-
-If a mock method has no `EXPECT_CALL` spec but is called, we say that it's an
-"uninteresting call", and the default action (which can be specified using
-`ON_CALL()`) of the method will be taken. Currently, an uninteresting call will
-also by default cause gMock to print a warning. (In the future, we might remove
-this warning by default.)
-
-However, sometimes you may want to ignore these uninteresting calls, and
-sometimes you may want to treat them as errors. gMock lets you make the decision
-on a per-mock-object basis.
-
-Suppose your test uses a mock class `MockFoo`:
-
-```cpp
-TEST(...) {
-  MockFoo mock_foo;
-  EXPECT_CALL(mock_foo, DoThis());
-  ... code that uses mock_foo ...
-}
-```
-
-If a method of `mock_foo` other than `DoThis()` is called, you will get a
-warning. However, if you rewrite your test to use `NiceMock<MockFoo>` instead,
-you can suppress the warning:
-
-```cpp
-using ::testing::NiceMock;
-
-TEST(...) {
-  NiceMock<MockFoo> mock_foo;
-  EXPECT_CALL(mock_foo, DoThis());
-  ... code that uses mock_foo ...
-}
-```
-
-`NiceMock<MockFoo>` is a subclass of `MockFoo`, so it can be used wherever
-`MockFoo` is accepted.
-
-It also works if `MockFoo`'s constructor takes some arguments, as
-`NiceMock<MockFoo>` "inherits" `MockFoo`'s constructors:
-
-```cpp
-using ::testing::NiceMock;
-
-TEST(...) {
-  NiceMock<MockFoo> mock_foo(5, "hi");  // Calls MockFoo(5, "hi").
-  EXPECT_CALL(mock_foo, DoThis());
-  ... code that uses mock_foo ...
-}
-```
-
-The usage of `StrictMock` is similar, except that it makes all uninteresting
-calls failures:
-
-```cpp
-using ::testing::StrictMock;
-
-TEST(...) {
-  StrictMock<MockFoo> mock_foo;
-  EXPECT_CALL(mock_foo, DoThis());
-  ... code that uses mock_foo ...
-
-  // The test will fail if a method of mock_foo other than DoThis()
-  // is called.
-}
-```
-
-NOTE: `NiceMock` and `StrictMock` only affects *uninteresting* calls (calls of
-*methods* with no expectations); they do not affect *unexpected* calls (calls of
-methods with expectations, but they don't match). See
-[Understanding Uninteresting vs Unexpected Calls](#uninteresting-vs-unexpected).
-
-There are some caveats though (I dislike them just as much as the next guy, but
-sadly they are side effects of C++'s limitations):
-
-1.  `NiceMock<MockFoo>` and `StrictMock<MockFoo>` only work for mock methods
-    defined using the `MOCK_METHOD` macro **directly** in the `MockFoo` class.
-    If a mock method is defined in a **base class** of `MockFoo`, the "nice" or
-    "strict" modifier may not affect it, depending on the compiler. In
-    particular, nesting `NiceMock` and `StrictMock` (e.g.
-    `NiceMock<StrictMock<MockFoo> >`) is **not** supported.
-2.  `NiceMock<MockFoo>` and `StrictMock<MockFoo>` may not work correctly if the
-    destructor of `MockFoo` is not virtual. We would like to fix this, but it
-    requires cleaning up existing tests. http://b/28934720 tracks the issue.
-3.  During the constructor or destructor of `MockFoo`, the mock object is *not*
-    nice or strict. This may cause surprises if the constructor or destructor
-    calls a mock method on `this` object. (This behavior, however, is consistent
-    with C++'s general rule: if a constructor or destructor calls a virtual
-    method of `this` object, that method is treated as non-virtual. In other
-    words, to the base class's constructor or destructor, `this` object behaves
-    like an instance of the base class, not the derived class. This rule is
-    required for safety. Otherwise a base constructor may use members of a
-    derived class before they are initialized, or a base destructor may use
-    members of a derived class after they have been destroyed.)
-
-Finally, you should be **very cautious** about when to use naggy or strict
-mocks, as they tend to make tests more brittle and harder to maintain. When you
-refactor your code without changing its externally visible behavior, ideally you
-shouldn't need to update any tests. If your code interacts with a naggy mock,
-however, you may start to get spammed with warnings as the result of your
-change. Worse, if your code interacts with a strict mock, your tests may start
-to fail and you'll be forced to fix them. Our general recommendation is to use
-nice mocks (not yet the default) most of the time, use naggy mocks (the current
-default) when developing or debugging tests, and use strict mocks only as the
-last resort.
-
-### Simplifying the Interface without Breaking Existing Code {#SimplerInterfaces}
-
-Sometimes a method has a long list of arguments that is mostly uninteresting.
-For example:
-
-```cpp
-class LogSink {
- public:
-  ...
-  virtual void send(LogSeverity severity, const char* full_filename,
-                    const char* base_filename, int line,
-                    const struct tm* tm_time,
-                    const char* message, size_t message_len) = 0;
-};
-```
-
-This method's argument list is lengthy and hard to work with (the `message`
-argument is not even 0-terminated). If we mock it as is, using the mock will be
-awkward. If, however, we try to simplify this interface, we'll need to fix all
-clients depending on it, which is often infeasible.
-
-The trick is to redispatch the method in the mock class:
-
-```cpp
-class ScopedMockLog : public LogSink {
- public:
-  ...
-  virtual void send(LogSeverity severity, const char* full_filename,
-                    const char* base_filename, int line, const tm* tm_time,
-                    const char* message, size_t message_len) {
-    // We are only interested in the log severity, full file name, and
-    // log message.
-    Log(severity, full_filename, std::string(message, message_len));
-  }
-
-  // Implements the mock method:
-  //
-  //   void Log(LogSeverity severity,
-  //            const string& file_path,
-  //            const string& message);
-  MOCK_METHOD(void, Log,
-              (LogSeverity severity, const string& file_path,
-               const string& message));
-};
-```
-
-By defining a new mock method with a trimmed argument list, we make the mock
-class more user-friendly.
-
-This technique may also be applied to make overloaded methods more amenable to
-mocking. For example, when overloads have been used to implement default
-arguments:
-
-```cpp
-class MockTurtleFactory : public TurtleFactory {
- public:
-  Turtle* MakeTurtle(int length, int weight) override { ... }
-  Turtle* MakeTurtle(int length, int weight, int speed) override { ... }
-
-  // the above methods delegate to this one:
-  MOCK_METHOD(Turtle*, DoMakeTurtle, ());
-};
-```
-
-This allows tests that don't care which overload was invoked to avoid specifying
-argument matchers:
-
-```cpp
-ON_CALL(factory, DoMakeTurtle)
-    .WillByDefault(MakeMockTurtle());
-```
-
-### Alternative to Mocking Concrete Classes
-
-Often you may find yourself using classes that don't implement interfaces. In
-order to test your code that uses such a class (let's call it `Concrete`), you
-may be tempted to make the methods of `Concrete` virtual and then mock it.
-
-Try not to do that.
-
-Making a non-virtual function virtual is a big decision. It creates an extension
-point where subclasses can tweak your class' behavior. This weakens your control
-on the class because now it's harder to maintain the class invariants. You
-should make a function virtual only when there is a valid reason for a subclass
-to override it.
-
-Mocking concrete classes directly is problematic as it creates a tight coupling
-between the class and the tests - any small change in the class may invalidate
-your tests and make test maintenance a pain.
-
-To avoid such problems, many programmers have been practicing "coding to
-interfaces": instead of talking to the `Concrete` class, your code would define
-an interface and talk to it. Then you implement that interface as an adaptor on
-top of `Concrete`. In tests, you can easily mock that interface to observe how
-your code is doing.
-
-This technique incurs some overhead:
-
-*   You pay the cost of virtual function calls (usually not a problem).
-*   There is more abstraction for the programmers to learn.
-
-However, it can also bring significant benefits in addition to better
-testability:
-
-*   `Concrete`'s API may not fit your problem domain very well, as you may not
-    be the only client it tries to serve. By designing your own interface, you
-    have a chance to tailor it to your need - you may add higher-level
-    functionalities, rename stuff, etc instead of just trimming the class. This
-    allows you to write your code (user of the interface) in a more natural way,
-    which means it will be more readable, more maintainable, and you'll be more
-    productive.
-*   If `Concrete`'s implementation ever has to change, you don't have to rewrite
-    everywhere it is used. Instead, you can absorb the change in your
-    implementation of the interface, and your other code and tests will be
-    insulated from this change.
-
-Some people worry that if everyone is practicing this technique, they will end
-up writing lots of redundant code. This concern is totally understandable.
-However, there are two reasons why it may not be the case:
-
-*   Different projects may need to use `Concrete` in different ways, so the best
-    interfaces for them will be different. Therefore, each of them will have its
-    own domain-specific interface on top of `Concrete`, and they will not be the
-    same code.
-*   If enough projects want to use the same interface, they can always share it,
-    just like they have been sharing `Concrete`. You can check in the interface
-    and the adaptor somewhere near `Concrete` (perhaps in a `contrib`
-    sub-directory) and let many projects use it.
-
-You need to weigh the pros and cons carefully for your particular problem, but
-I'd like to assure you that the Java community has been practicing this for a
-long time and it's a proven effective technique applicable in a wide variety of
-situations. :-)
-
-### Delegating Calls to a Fake {#DelegatingToFake}
-
-Some times you have a non-trivial fake implementation of an interface. For
-example:
-
-```cpp
-class Foo {
- public:
-  virtual ~Foo() {}
-  virtual char DoThis(int n) = 0;
-  virtual void DoThat(const char* s, int* p) = 0;
-};
-
-class FakeFoo : public Foo {
- public:
-  char DoThis(int n) override {
-    return (n > 0) ? '+' :
-           (n < 0) ? '-' : '0';
-  }
-
-  void DoThat(const char* s, int* p) override {
-    *p = strlen(s);
-  }
-};
-```
-
-Now you want to mock this interface such that you can set expectations on it.
-However, you also want to use `FakeFoo` for the default behavior, as duplicating
-it in the mock object is, well, a lot of work.
-
-When you define the mock class using gMock, you can have it delegate its default
-action to a fake class you already have, using this pattern:
-
-```cpp
-class MockFoo : public Foo {
- public:
-  // Normal mock method definitions using gMock.
-  MOCK_METHOD(char, DoThis, (int n), (override));
-  MOCK_METHOD(void, DoThat, (const char* s, int* p), (override));
-
-  // Delegates the default actions of the methods to a FakeFoo object.
-  // This must be called *before* the custom ON_CALL() statements.
-  void DelegateToFake() {
-    ON_CALL(*this, DoThis).WillByDefault([this](int n) {
-      return fake_.DoThis(n);
-    });
-    ON_CALL(*this, DoThat).WillByDefault([this](const char* s, int* p) {
-      fake_.DoThat(s, p);
-    });
-  }
-
- private:
-  FakeFoo fake_;  // Keeps an instance of the fake in the mock.
-};
-```
-
-With that, you can use `MockFoo` in your tests as usual. Just remember that if
-you don't explicitly set an action in an `ON_CALL()` or `EXPECT_CALL()`, the
-fake will be called upon to do it.:
-
-```cpp
-using ::testing::_;
-
-TEST(AbcTest, Xyz) {
-  MockFoo foo;
-
-  foo.DelegateToFake();  // Enables the fake for delegation.
-
-  // Put your ON_CALL(foo, ...)s here, if any.
-
-  // No action specified, meaning to use the default action.
-  EXPECT_CALL(foo, DoThis(5));
-  EXPECT_CALL(foo, DoThat(_, _));
-
-  int n = 0;
-  EXPECT_EQ('+', foo.DoThis(5));  // FakeFoo::DoThis() is invoked.
-  foo.DoThat("Hi", &n);  // FakeFoo::DoThat() is invoked.
-  EXPECT_EQ(2, n);
-}
-```
-
-**Some tips:**
-
-*   If you want, you can still override the default action by providing your own
-    `ON_CALL()` or using `.WillOnce()` / `.WillRepeatedly()` in `EXPECT_CALL()`.
-*   In `DelegateToFake()`, you only need to delegate the methods whose fake
-    implementation you intend to use.
-
-*   The general technique discussed here works for overloaded methods, but
-    you'll need to tell the compiler which version you mean. To disambiguate a
-    mock function (the one you specify inside the parentheses of `ON_CALL()`),
-    use [this technique](#SelectOverload); to disambiguate a fake function (the
-    one you place inside `Invoke()`), use a `static_cast` to specify the
-    function's type. For instance, if class `Foo` has methods `char DoThis(int
-    n)` and `bool DoThis(double x) const`, and you want to invoke the latter,
-    you need to write `Invoke(&fake_, static_cast<bool (FakeFoo::*)(double)
-    const>(&FakeFoo::DoThis))` instead of `Invoke(&fake_, &FakeFoo::DoThis)`
-    (The strange-looking thing inside the angled brackets of `static_cast` is
-    the type of a function pointer to the second `DoThis()` method.).
-
-*   Having to mix a mock and a fake is often a sign of something gone wrong.
-    Perhaps you haven't got used to the interaction-based way of testing yet. Or
-    perhaps your interface is taking on too many roles and should be split up.
-    Therefore, **don't abuse this**. We would only recommend to do it as an
-    intermediate step when you are refactoring your code.
-
-Regarding the tip on mixing a mock and a fake, here's an example on why it may
-be a bad sign: Suppose you have a class `System` for low-level system
-operations. In particular, it does file and I/O operations. And suppose you want
-to test how your code uses `System` to do I/O, and you just want the file
-operations to work normally. If you mock out the entire `System` class, you'll
-have to provide a fake implementation for the file operation part, which
-suggests that `System` is taking on too many roles.
-
-Instead, you can define a `FileOps` interface and an `IOOps` interface and split
-`System`'s functionalities into the two. Then you can mock `IOOps` without
-mocking `FileOps`.
-
-### Delegating Calls to a Real Object
-
-When using testing doubles (mocks, fakes, stubs, and etc), sometimes their
-behaviors will differ from those of the real objects. This difference could be
-either intentional (as in simulating an error such that you can test the error
-handling code) or unintentional. If your mocks have different behaviors than the
-real objects by mistake, you could end up with code that passes the tests but
-fails in production.
-
-You can use the *delegating-to-real* technique to ensure that your mock has the
-same behavior as the real object while retaining the ability to validate calls.
-This technique is very similar to the [delegating-to-fake](#DelegatingToFake)
-technique, the difference being that we use a real object instead of a fake.
-Here's an example:
-
-```cpp
-using ::testing::AtLeast;
-
-class MockFoo : public Foo {
- public:
-  MockFoo() {
-    // By default, all calls are delegated to the real object.
-    ON_CALL(*this, DoThis).WillByDefault([this](int n) {
-      return real_.DoThis(n);
-    });
-    ON_CALL(*this, DoThat).WillByDefault([this](const char* s, int* p) {
-      real_.DoThat(s, p);
-    });
-    ...
-  }
-  MOCK_METHOD(char, DoThis, ...);
-  MOCK_METHOD(void, DoThat, ...);
-  ...
- private:
-  Foo real_;
-};
-
-...
-  MockFoo mock;
-  EXPECT_CALL(mock, DoThis())
-      .Times(3);
-  EXPECT_CALL(mock, DoThat("Hi"))
-      .Times(AtLeast(1));
-  ... use mock in test ...
-```
-
-With this, gMock will verify that your code made the right calls (with the right
-arguments, in the right order, called the right number of times, etc), and a
-real object will answer the calls (so the behavior will be the same as in
-production). This gives you the best of both worlds.
-
-### Delegating Calls to a Parent Class
-
-Ideally, you should code to interfaces, whose methods are all pure virtual. In
-reality, sometimes you do need to mock a virtual method that is not pure (i.e,
-it already has an implementation). For example:
-
-```cpp
-class Foo {
- public:
-  virtual ~Foo();
-
-  virtual void Pure(int n) = 0;
-  virtual int Concrete(const char* str) { ... }
-};
-
-class MockFoo : public Foo {
- public:
-  // Mocking a pure method.
-  MOCK_METHOD(void, Pure, (int n), (override));
-  // Mocking a concrete method.  Foo::Concrete() is shadowed.
-  MOCK_METHOD(int, Concrete, (const char* str), (override));
-};
-```
-
-Sometimes you may want to call `Foo::Concrete()` instead of
-`MockFoo::Concrete()`. Perhaps you want to do it as part of a stub action, or
-perhaps your test doesn't need to mock `Concrete()` at all (but it would be
-oh-so painful to have to define a new mock class whenever you don't need to mock
-one of its methods).
-
-The trick is to leave a back door in your mock class for accessing the real
-methods in the base class:
-
-```cpp
-class MockFoo : public Foo {
- public:
-  // Mocking a pure method.
-  MOCK_METHOD(void, Pure, (int n), (override));
-  // Mocking a concrete method.  Foo::Concrete() is shadowed.
-  MOCK_METHOD(int, Concrete, (const char* str), (override));
-
-  // Use this to call Concrete() defined in Foo.
-  int FooConcrete(const char* str) { return Foo::Concrete(str); }
-};
-```
-
-Now, you can call `Foo::Concrete()` inside an action by:
-
-```cpp
-...
-  EXPECT_CALL(foo, Concrete).WillOnce([&foo](const char* str) {
-    return foo.FooConcrete(str);
-  });
-```
-
-or tell the mock object that you don't want to mock `Concrete()`:
-
-```cpp
-...
-  ON_CALL(foo, Concrete).WillByDefault([&foo](const char* str) {
-    return foo.FooConcrete(str);
-  });
-```
-
-(Why don't we just write `{ return foo.Concrete(str); }`? If you do that,
-`MockFoo::Concrete()` will be called (and cause an infinite recursion) since
-`Foo::Concrete()` is virtual. That's just how C++ works.)
-
-## Using Matchers
-
-### Matching Argument Values Exactly
-
-You can specify exactly which arguments a mock method is expecting:
-
-```cpp
-using ::testing::Return;
-...
-  EXPECT_CALL(foo, DoThis(5))
-      .WillOnce(Return('a'));
-  EXPECT_CALL(foo, DoThat("Hello", bar));
-```
-
-### Using Simple Matchers
-
-You can use matchers to match arguments that have a certain property:
-
-```cpp
-using ::testing::NotNull;
-using ::testing::Return;
-...
-  EXPECT_CALL(foo, DoThis(Ge(5)))  // The argument must be >= 5.
-      .WillOnce(Return('a'));
-  EXPECT_CALL(foo, DoThat("Hello", NotNull()));
-      // The second argument must not be NULL.
-```
-
-A frequently used matcher is `_`, which matches anything:
-
-```cpp
-  EXPECT_CALL(foo, DoThat(_, NotNull()));
-```
-<!-- GOOGLETEST_CM0022 DO NOT DELETE -->
-
-### Combining Matchers {#CombiningMatchers}
-
-You can build complex matchers from existing ones using `AllOf()`,
-`AllOfArray()`, `AnyOf()`, `AnyOfArray()` and `Not()`:
-
-```cpp
-using ::testing::AllOf;
-using ::testing::Gt;
-using ::testing::HasSubstr;
-using ::testing::Ne;
-using ::testing::Not;
-...
-  // The argument must be > 5 and != 10.
-  EXPECT_CALL(foo, DoThis(AllOf(Gt(5),
-                                Ne(10))));
-
-  // The first argument must not contain sub-string "blah".
-  EXPECT_CALL(foo, DoThat(Not(HasSubstr("blah")),
-                          NULL));
-```
-
-### Casting Matchers {#SafeMatcherCast}
-
-gMock matchers are statically typed, meaning that the compiler can catch your
-mistake if you use a matcher of the wrong type (for example, if you use `Eq(5)`
-to match a `string` argument). Good for you!
-
-Sometimes, however, you know what you're doing and want the compiler to give you
-some slack. One example is that you have a matcher for `long` and the argument
-you want to match is `int`. While the two types aren't exactly the same, there
-is nothing really wrong with using a `Matcher<long>` to match an `int` - after
-all, we can first convert the `int` argument to a `long` losslessly before
-giving it to the matcher.
-
-To support this need, gMock gives you the `SafeMatcherCast<T>(m)` function. It
-casts a matcher `m` to type `Matcher<T>`. To ensure safety, gMock checks that
-(let `U` be the type `m` accepts :
-
-1.  Type `T` can be *implicitly* cast to type `U`;
-2.  When both `T` and `U` are built-in arithmetic types (`bool`, integers, and
-    floating-point numbers), the conversion from `T` to `U` is not lossy (in
-    other words, any value representable by `T` can also be represented by `U`);
-    and
-3.  When `U` is a reference, `T` must also be a reference (as the underlying
-    matcher may be interested in the address of the `U` value).
-
-The code won't compile if any of these conditions isn't met.
-
-Here's one example:
-
-```cpp
-using ::testing::SafeMatcherCast;
-
-// A base class and a child class.
-class Base { ... };
-class Derived : public Base { ... };
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD(void, DoThis, (Derived* derived), (override));
-};
-
-...
-  MockFoo foo;
-  // m is a Matcher<Base*> we got from somewhere.
-  EXPECT_CALL(foo, DoThis(SafeMatcherCast<Derived*>(m)));
-```
-
-If you find `SafeMatcherCast<T>(m)` too limiting, you can use a similar function
-`MatcherCast<T>(m)`. The difference is that `MatcherCast` works as long as you
-can `static_cast` type `T` to type `U`.
-
-`MatcherCast` essentially lets you bypass C++'s type system (`static_cast` isn't
-always safe as it could throw away information, for example), so be careful not
-to misuse/abuse it.
-
-### Selecting Between Overloaded Functions {#SelectOverload}
-
-If you expect an overloaded function to be called, the compiler may need some
-help on which overloaded version it is.
-
-To disambiguate functions overloaded on the const-ness of this object, use the
-`Const()` argument wrapper.
-
-```cpp
-using ::testing::ReturnRef;
-
-class MockFoo : public Foo {
-  ...
-  MOCK_METHOD(Bar&, GetBar, (), (override));
-  MOCK_METHOD(const Bar&, GetBar, (), (const, override));
-};
-
-...
-  MockFoo foo;
-  Bar bar1, bar2;
-  EXPECT_CALL(foo, GetBar())         // The non-const GetBar().
-      .WillOnce(ReturnRef(bar1));
-  EXPECT_CALL(Const(foo), GetBar())  // The const GetBar().
-      .WillOnce(ReturnRef(bar2));
-```
-
-(`Const()` is defined by gMock and returns a `const` reference to its argument.)
-
-To disambiguate overloaded functions with the same number of arguments but
-different argument types, you may need to specify the exact type of a matcher,
-either by wrapping your matcher in `Matcher<type>()`, or using a matcher whose
-type is fixed (`TypedEq<type>`, `An<type>()`, etc):
-
-```cpp
-using ::testing::An;
-using ::testing::Matcher;
-using ::testing::TypedEq;
-
-class MockPrinter : public Printer {
- public:
-  MOCK_METHOD(void, Print, (int n), (override));
-  MOCK_METHOD(void, Print, (char c), (override));
-};
-
-TEST(PrinterTest, Print) {
-  MockPrinter printer;
-
-  EXPECT_CALL(printer, Print(An<int>()));            // void Print(int);
-  EXPECT_CALL(printer, Print(Matcher<int>(Lt(5))));  // void Print(int);
-  EXPECT_CALL(printer, Print(TypedEq<char>('a')));   // void Print(char);
-
-  printer.Print(3);
-  printer.Print(6);
-  printer.Print('a');
-}
-```
-
-### Performing Different Actions Based on the Arguments
-
-When a mock method is called, the *last* matching expectation that's still
-active will be selected (think "newer overrides older"). So, you can make a
-method do different things depending on its argument values like this:
-
-```cpp
-using ::testing::_;
-using ::testing::Lt;
-using ::testing::Return;
-...
-  // The default case.
-  EXPECT_CALL(foo, DoThis(_))
-      .WillRepeatedly(Return('b'));
-  // The more specific case.
-  EXPECT_CALL(foo, DoThis(Lt(5)))
-      .WillRepeatedly(Return('a'));
-```
-
-Now, if `foo.DoThis()` is called with a value less than 5, `'a'` will be
-returned; otherwise `'b'` will be returned.
-
-### Matching Multiple Arguments as a Whole
-
-Sometimes it's not enough to match the arguments individually. For example, we
-may want to say that the first argument must be less than the second argument.
-The `With()` clause allows us to match all arguments of a mock function as a
-whole. For example,
-
-```cpp
-using ::testing::_;
-using ::testing::Ne;
-using ::testing::Lt;
-...
-  EXPECT_CALL(foo, InRange(Ne(0), _))
-      .With(Lt());
-```
-
-says that the first argument of `InRange()` must not be 0, and must be less than
-the second argument.
-
-The expression inside `With()` must be a matcher of type
-`Matcher< ::std::tuple<A1, ..., An> >`, where `A1`, ..., `An` are the types of
-the function arguments.
-
-You can also write `AllArgs(m)` instead of `m` inside `.With()`. The two forms
-are equivalent, but `.With(AllArgs(Lt()))` is more readable than `.With(Lt())`.
-
-You can use `Args<k1, ..., kn>(m)` to match the `n` selected arguments (as a
-tuple) against `m`. For example,
-
-```cpp
-using ::testing::_;
-using ::testing::AllOf;
-using ::testing::Args;
-using ::testing::Lt;
-...
-  EXPECT_CALL(foo, Blah)
-      .With(AllOf(Args<0, 1>(Lt()), Args<1, 2>(Lt())));
-```
-
-says that `Blah` will be called with arguments `x`, `y`, and `z` where `x < y <
-z`. Note that in this example, it wasn't necessary specify the positional
-matchers.
-
-As a convenience and example, gMock provides some matchers for 2-tuples,
-including the `Lt()` matcher above. See [here](#MultiArgMatchers) for the
-complete list.
-
-Note that if you want to pass the arguments to a predicate of your own (e.g.
-`.With(Args<0, 1>(Truly(&MyPredicate)))`), that predicate MUST be written to
-take a `::std::tuple` as its argument; gMock will pass the `n` selected
-arguments as *one* single tuple to the predicate.
-
-### Using Matchers as Predicates
-
-Have you noticed that a matcher is just a fancy predicate that also knows how to
-describe itself? Many existing algorithms take predicates as arguments (e.g.
-those defined in STL's `<algorithm>` header), and it would be a shame if gMock
-matchers were not allowed to participate.
-
-Luckily, you can use a matcher where a unary predicate functor is expected by
-wrapping it inside the `Matches()` function. For example,
-
-```cpp
-#include <algorithm>
-#include <vector>
-
-using ::testing::Matches;
-using ::testing::Ge;
-
-vector<int> v;
-...
-// How many elements in v are >= 10?
-const int count = count_if(v.begin(), v.end(), Matches(Ge(10)));
-```
-
-Since you can build complex matchers from simpler ones easily using gMock, this
-gives you a way to conveniently construct composite predicates (doing the same
-using STL's `<functional>` header is just painful). For example, here's a
-predicate that's satisfied by any number that is >= 0, <= 100, and != 50:
-
-```cpp
-using testing::AllOf;
-using testing::Ge;
-using testing::Le;
-using testing::Matches;
-using testing::Ne;
-...
-Matches(AllOf(Ge(0), Le(100), Ne(50)))
-```
-
-### Using Matchers in googletest Assertions
-
-Since matchers are basically predicates that also know how to describe
-themselves, there is a way to take advantage of them in googletest assertions.
-It's called `ASSERT_THAT` and `EXPECT_THAT`:
-
-```cpp
-  ASSERT_THAT(value, matcher);  // Asserts that value matches matcher.
-  EXPECT_THAT(value, matcher);  // The non-fatal version.
-```
-
-For example, in a googletest test you can write:
-
-```cpp
-#include "gmock/gmock.h"
-
-using ::testing::AllOf;
-using ::testing::Ge;
-using ::testing::Le;
-using ::testing::MatchesRegex;
-using ::testing::StartsWith;
-
-...
-  EXPECT_THAT(Foo(), StartsWith("Hello"));
-  EXPECT_THAT(Bar(), MatchesRegex("Line \\d+"));
-  ASSERT_THAT(Baz(), AllOf(Ge(5), Le(10)));
-```
-
-which (as you can probably guess) executes `Foo()`, `Bar()`, and `Baz()`, and
-verifies that:
-
-*   `Foo()` returns a string that starts with `"Hello"`.
-*   `Bar()` returns a string that matches regular expression `"Line \\d+"`.
-*   `Baz()` returns a number in the range [5, 10].
-
-The nice thing about these macros is that *they read like English*. They
-generate informative messages too. For example, if the first `EXPECT_THAT()`
-above fails, the message will be something like:
-
-```cpp
-Value of: Foo()
-  Actual: "Hi, world!"
-Expected: starts with "Hello"
-```
-
-**Credit:** The idea of `(ASSERT|EXPECT)_THAT` was borrowed from Joe Walnes'
-Hamcrest project, which adds `assertThat()` to JUnit.
-
-### Using Predicates as Matchers
-
-gMock provides a [built-in set](#MatcherList) of matchers. In case you find them
-lacking, you can use an arbitrary unary predicate function or functor as a
-matcher - as long as the predicate accepts a value of the type you want. You do
-this by wrapping the predicate inside the `Truly()` function, for example:
-
-```cpp
-using ::testing::Truly;
-
-int IsEven(int n) { return (n % 2) == 0 ? 1 : 0; }
-...
-  // Bar() must be called with an even number.
-  EXPECT_CALL(foo, Bar(Truly(IsEven)));
-```
-
-Note that the predicate function / functor doesn't have to return `bool`. It
-works as long as the return value can be used as the condition in in statement
-`if (condition) ...`.
-
-<!-- GOOGLETEST_CM0023 DO NOT DELETE -->
-
-### Matching Arguments that Are Not Copyable
-
-When you do an `EXPECT_CALL(mock_obj, Foo(bar))`, gMock saves away a copy of
-`bar`. When `Foo()` is called later, gMock compares the argument to `Foo()` with
-the saved copy of `bar`. This way, you don't need to worry about `bar` being
-modified or destroyed after the `EXPECT_CALL()` is executed. The same is true
-when you use matchers like `Eq(bar)`, `Le(bar)`, and so on.
-
-But what if `bar` cannot be copied (i.e. has no copy constructor)? You could
-define your own matcher function or callback and use it with `Truly()`, as the
-previous couple of recipes have shown. Or, you may be able to get away from it
-if you can guarantee that `bar` won't be changed after the `EXPECT_CALL()` is
-executed. Just tell gMock that it should save a reference to `bar`, instead of a
-copy of it. Here's how:
-
-```cpp
-using ::testing::ByRef;
-using ::testing::Eq;
-using ::testing::Lt;
-...
-  // Expects that Foo()'s argument == bar.
-  EXPECT_CALL(mock_obj, Foo(Eq(ByRef(bar))));
-
-  // Expects that Foo()'s argument < bar.
-  EXPECT_CALL(mock_obj, Foo(Lt(ByRef(bar))));
-```
-
-Remember: if you do this, don't change `bar` after the `EXPECT_CALL()`, or the
-result is undefined.
-
-### Validating a Member of an Object
-
-Often a mock function takes a reference to object as an argument. When matching
-the argument, you may not want to compare the entire object against a fixed
-object, as that may be over-specification. Instead, you may need to validate a
-certain member variable or the result of a certain getter method of the object.
-You can do this with `Field()` and `Property()`. More specifically,
-
-```cpp
-Field(&Foo::bar, m)
-```
-
-is a matcher that matches a `Foo` object whose `bar` member variable satisfies
-matcher `m`.
-
-```cpp
-Property(&Foo::baz, m)
-```
-
-is a matcher that matches a `Foo` object whose `baz()` method returns a value
-that satisfies matcher `m`.
-
-For example:
-
-<!-- mdformat off(github rendering does not support multiline tables) -->
-| Expression                   | Description                              |
-| :--------------------------- | :--------------------------------------- |
-| `Field(&Foo::number, Ge(3))` | Matches `x` where `x.number >= 3`.       |
-| `Property(&Foo::name,  StartsWith("John "))` | Matches `x` where `x.name()` starts with  `"John "`. |
-<!-- mdformat on -->
-
-Note that in `Property(&Foo::baz, ...)`, method `baz()` must take no argument
-and be declared as `const`.
-
-BTW, `Field()` and `Property()` can also match plain pointers to objects. For
-instance,
-
-```cpp
-using ::testing::Field;
-using ::testing::Ge;
-...
-Field(&Foo::number, Ge(3))
-```
-
-matches a plain pointer `p` where `p->number >= 3`. If `p` is `NULL`, the match
-will always fail regardless of the inner matcher.
-
-What if you want to validate more than one members at the same time? Remember
-that there are [`AllOf()` and `AllOfArray()`](#CombiningMatchers).
-
-Finally `Field()` and `Property()` provide overloads that take the field or
-property names as the first argument to include it in the error message. This
-can be useful when creating combined matchers.
-
-```cpp
-using ::testing::AllOf;
-using ::testing::Field;
-using ::testing::Matcher;
-using ::testing::SafeMatcherCast;
-
-Matcher<Foo> IsFoo(const Foo& foo) {
-  return AllOf(Field("some_field", &Foo::some_field, foo.some_field),
-               Field("other_field", &Foo::other_field, foo.other_field),
-               Field("last_field", &Foo::last_field, foo.last_field));
-}
-```
-
-### Validating the Value Pointed to by a Pointer Argument
-
-C++ functions often take pointers as arguments. You can use matchers like
-`IsNull()`, `NotNull()`, and other comparison matchers to match a pointer, but
-what if you want to make sure the value *pointed to* by the pointer, instead of
-the pointer itself, has a certain property? Well, you can use the `Pointee(m)`
-matcher.
-
-`Pointee(m)` matches a pointer if and only if `m` matches the value the pointer
-points to. For example:
-
-```cpp
-using ::testing::Ge;
-using ::testing::Pointee;
-...
-  EXPECT_CALL(foo, Bar(Pointee(Ge(3))));
-```
-
-expects `foo.Bar()` to be called with a pointer that points to a value greater
-than or equal to 3.
-
-One nice thing about `Pointee()` is that it treats a `NULL` pointer as a match
-failure, so you can write `Pointee(m)` instead of
-
-```cpp
-using ::testing::AllOf;
-using ::testing::NotNull;
-using ::testing::Pointee;
-...
-  AllOf(NotNull(), Pointee(m))
-```
-
-without worrying that a `NULL` pointer will crash your test.
-
-Also, did we tell you that `Pointee()` works with both raw pointers **and**
-smart pointers (`std::unique_ptr`, `std::shared_ptr`, etc)?
-
-What if you have a pointer to pointer? You guessed it - you can use nested
-`Pointee()` to probe deeper inside the value. For example,
-`Pointee(Pointee(Lt(3)))` matches a pointer that points to a pointer that points
-to a number less than 3 (what a mouthful...).
-
-### Testing a Certain Property of an Object
-
-Sometimes you want to specify that an object argument has a certain property,
-but there is no existing matcher that does this. If you want good error
-messages, you should [define a matcher](#NewMatchers). If you want to do it
-quick and dirty, you could get away with writing an ordinary function.
-
-Let's say you have a mock function that takes an object of type `Foo`, which has
-an `int bar()` method and an `int baz()` method, and you want to constrain that
-the argument's `bar()` value plus its `baz()` value is a given number. Here's
-how you can define a matcher to do it:
-
-```cpp
-using ::testing::Matcher;
-using ::testing::MatcherInterface;
-using ::testing::MatchResultListener;
-
-class BarPlusBazEqMatcher : public MatcherInterface<const Foo&> {
- public:
-  explicit BarPlusBazEqMatcher(int expected_sum)
-      : expected_sum_(expected_sum) {}
-
-  bool MatchAndExplain(const Foo& foo,
-                       MatchResultListener* /* listener */) const override {
-    return (foo.bar() + foo.baz()) == expected_sum_;
-  }
-
-  void DescribeTo(::std::ostream* os) const override {
-    *os << "bar() + baz() equals " << expected_sum_;
-  }
-
-  void DescribeNegationTo(::std::ostream* os) const override {
-    *os << "bar() + baz() does not equal " << expected_sum_;
-  }
- private:
-  const int expected_sum_;
-};
-
-Matcher<const Foo&> BarPlusBazEq(int expected_sum) {
-  return MakeMatcher(new BarPlusBazEqMatcher(expected_sum));
-}
-
-...
-  EXPECT_CALL(..., DoThis(BarPlusBazEq(5)))...;
-```
-
-### Matching Containers
-
-Sometimes an STL container (e.g. list, vector, map, ...) is passed to a mock
-function and you may want to validate it. Since most STL containers support the
-`==` operator, you can write `Eq(expected_container)` or simply
-`expected_container` to match a container exactly.
-
-Sometimes, though, you may want to be more flexible (for example, the first
-element must be an exact match, but the second element can be any positive
-number, and so on). Also, containers used in tests often have a small number of
-elements, and having to define the expected container out-of-line is a bit of a
-hassle.
-
-You can use the `ElementsAre()` or `UnorderedElementsAre()` matcher in such
-cases:
-
-```cpp
-using ::testing::_;
-using ::testing::ElementsAre;
-using ::testing::Gt;
-...
-  MOCK_METHOD(void, Foo, (const vector<int>& numbers), (override));
-...
-  EXPECT_CALL(mock, Foo(ElementsAre(1, Gt(0), _, 5)));
-```
-
-The above matcher says that the container must have 4 elements, which must be 1,
-greater than 0, anything, and 5 respectively.
-
-If you instead write:
-
-```cpp
-using ::testing::_;
-using ::testing::Gt;
-using ::testing::UnorderedElementsAre;
-...
-  MOCK_METHOD(void, Foo, (const vector<int>& numbers), (override));
-...
-  EXPECT_CALL(mock, Foo(UnorderedElementsAre(1, Gt(0), _, 5)));
-```
-
-It means that the container must have 4 elements, which (under some permutation)
-must be 1, greater than 0, anything, and 5 respectively.
-
-As an alternative you can place the arguments in a C-style array and use
-`ElementsAreArray()` or `UnorderedElementsAreArray()` instead:
-
-```cpp
-using ::testing::ElementsAreArray;
-...
-  // ElementsAreArray accepts an array of element values.
-  const int expected_vector1[] = {1, 5, 2, 4, ...};
-  EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector1)));
-
-  // Or, an array of element matchers.
-  Matcher<int> expected_vector2[] = {1, Gt(2), _, 3, ...};
-  EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector2)));
-```
-
-In case the array needs to be dynamically created (and therefore the array size
-cannot be inferred by the compiler), you can give `ElementsAreArray()` an
-additional argument to specify the array size:
-
-```cpp
-using ::testing::ElementsAreArray;
-...
-  int* const expected_vector3 = new int[count];
-  ... fill expected_vector3 with values ...
-  EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector3, count)));
-```
-
-Use `Pair` when comparing maps or other associative containers.
-
-```cpp
-using testing::ElementsAre;
-using testing::Pair;
-...
-  std::map<string, int> m = {{"a", 1}, {"b", 2}, {"c", 3}};
-  EXPECT_THAT(m, ElementsAre(Pair("a", 1), Pair("b", 2), Pair("c", 3)));
-```
-
-**Tips:**
-
-*   `ElementsAre*()` can be used to match *any* container that implements the
-    STL iterator pattern (i.e. it has a `const_iterator` type and supports
-    `begin()/end()`), not just the ones defined in STL. It will even work with
-    container types yet to be written - as long as they follows the above
-    pattern.
-*   You can use nested `ElementsAre*()` to match nested (multi-dimensional)
-    containers.
-*   If the container is passed by pointer instead of by reference, just write
-    `Pointee(ElementsAre*(...))`.
-*   The order of elements *matters* for `ElementsAre*()`. If you are using it
-    with containers whose element order are undefined (e.g. `hash_map`) you
-    should use `WhenSorted` around `ElementsAre`.
-
-### Sharing Matchers
-
-Under the hood, a gMock matcher object consists of a pointer to a ref-counted
-implementation object. Copying matchers is allowed and very efficient, as only
-the pointer is copied. When the last matcher that references the implementation
-object dies, the implementation object will be deleted.
-
-Therefore, if you have some complex matcher that you want to use again and
-again, there is no need to build it everytime. Just assign it to a matcher
-variable and use that variable repeatedly! For example,
-
-```cpp
-using ::testing::AllOf;
-using ::testing::Gt;
-using ::testing::Le;
-using ::testing::Matcher;
-...
-  Matcher<int> in_range = AllOf(Gt(5), Le(10));
-  ... use in_range as a matcher in multiple EXPECT_CALLs ...
-```
-
-### Matchers must have no side-effects {#PureMatchers}
-
-WARNING: gMock does not guarantee when or how many times a matcher will be
-invoked. Therefore, all matchers must be *purely functional*: they cannot have
-any side effects, and the match result must not depend on anything other than
-the matcher's parameters and the value being matched.
-
-This requirement must be satisfied no matter how a matcher is defined (e.g., if
-it is one of the standard matchers, or a custom matcher). In particular, a
-matcher can never call a mock function, as that will affect the state of the
-mock object and gMock.
-
-## Setting Expectations
-
-### Knowing When to Expect {#UseOnCall}
-
-<!-- GOOGLETEST_CM0018 DO NOT DELETE -->
-
-**`ON_CALL`** is likely the *single most under-utilized construct* in gMock.
-
-There are basically two constructs for defining the behavior of a mock object:
-`ON_CALL` and `EXPECT_CALL`. The difference? `ON_CALL` defines what happens when
-a mock method is called, but <em>doesn't imply any expectation on the method
-being called</em>. `EXPECT_CALL` not only defines the behavior, but also sets an
-expectation that <em>the method will be called with the given arguments, for the
-given number of times</em> (and *in the given order* when you specify the order
-too).
-
-Since `EXPECT_CALL` does more, isn't it better than `ON_CALL`? Not really. Every
-`EXPECT_CALL` adds a constraint on the behavior of the code under test. Having
-more constraints than necessary is *baaad* - even worse than not having enough
-constraints.
-
-This may be counter-intuitive. How could tests that verify more be worse than
-tests that verify less? Isn't verification the whole point of tests?
-
-The answer lies in *what* a test should verify. **A good test verifies the
-contract of the code.** If a test over-specifies, it doesn't leave enough
-freedom to the implementation. As a result, changing the implementation without
-breaking the contract (e.g. refactoring and optimization), which should be
-perfectly fine to do, can break such tests. Then you have to spend time fixing
-them, only to see them broken again the next time the implementation is changed.
-
-Keep in mind that one doesn't have to verify more than one property in one test.
-In fact, **it's a good style to verify only one thing in one test.** If you do
-that, a bug will likely break only one or two tests instead of dozens (which
-case would you rather debug?). If you are also in the habit of giving tests
-descriptive names that tell what they verify, you can often easily guess what's
-wrong just from the test log itself.
-
-So use `ON_CALL` by default, and only use `EXPECT_CALL` when you actually intend
-to verify that the call is made. For example, you may have a bunch of `ON_CALL`s
-in your test fixture to set the common mock behavior shared by all tests in the
-same group, and write (scarcely) different `EXPECT_CALL`s in different `TEST_F`s
-to verify different aspects of the code's behavior. Compared with the style
-where each `TEST` has many `EXPECT_CALL`s, this leads to tests that are more
-resilient to implementational changes (and thus less likely to require
-maintenance) and makes the intent of the tests more obvious (so they are easier
-to maintain when you do need to maintain them).
-
-If you are bothered by the "Uninteresting mock function call" message printed
-when a mock method without an `EXPECT_CALL` is called, you may use a `NiceMock`
-instead to suppress all such messages for the mock object, or suppress the
-message for specific methods by adding `EXPECT_CALL(...).Times(AnyNumber())`. DO
-NOT suppress it by blindly adding an `EXPECT_CALL(...)`, or you'll have a test
-that's a pain to maintain.
-
-### Ignoring Uninteresting Calls
-
-If you are not interested in how a mock method is called, just don't say
-anything about it. In this case, if the method is ever called, gMock will
-perform its default action to allow the test program to continue. If you are not
-happy with the default action taken by gMock, you can override it using
-`DefaultValue<T>::Set()` (described [here](#DefaultValue)) or `ON_CALL()`.
-
-Please note that once you expressed interest in a particular mock method (via
-`EXPECT_CALL()`), all invocations to it must match some expectation. If this
-function is called but the arguments don't match any `EXPECT_CALL()` statement,
-it will be an error.
-
-### Disallowing Unexpected Calls
-
-If a mock method shouldn't be called at all, explicitly say so:
-
-```cpp
-using ::testing::_;
-...
-  EXPECT_CALL(foo, Bar(_))
-      .Times(0);
-```
-
-If some calls to the method are allowed, but the rest are not, just list all the
-expected calls:
-
-```cpp
-using ::testing::AnyNumber;
-using ::testing::Gt;
-...
-  EXPECT_CALL(foo, Bar(5));
-  EXPECT_CALL(foo, Bar(Gt(10)))
-      .Times(AnyNumber());
-```
-
-A call to `foo.Bar()` that doesn't match any of the `EXPECT_CALL()` statements
-will be an error.
-
-### Understanding Uninteresting vs Unexpected Calls {#uninteresting-vs-unexpected}
-
-*Uninteresting* calls and *unexpected* calls are different concepts in gMock.
-*Very* different.
-
-A call `x.Y(...)` is **uninteresting** if there's *not even a single*
-`EXPECT_CALL(x, Y(...))` set. In other words, the test isn't interested in the
-`x.Y()` method at all, as evident in that the test doesn't care to say anything
-about it.
-
-A call `x.Y(...)` is **unexpected** if there are *some* `EXPECT_CALL(x,
-Y(...))`s set, but none of them matches the call. Put another way, the test is
-interested in the `x.Y()` method (therefore it explicitly sets some
-`EXPECT_CALL` to verify how it's called); however, the verification fails as the
-test doesn't expect this particular call to happen.
-
-**An unexpected call is always an error,** as the code under test doesn't behave
-the way the test expects it to behave.
-
-**By default, an uninteresting call is not an error,** as it violates no
-constraint specified by the test. (gMock's philosophy is that saying nothing
-means there is no constraint.) However, it leads to a warning, as it *might*
-indicate a problem (e.g. the test author might have forgotten to specify a
-constraint).
-
-In gMock, `NiceMock` and `StrictMock` can be used to make a mock class "nice" or
-"strict". How does this affect uninteresting calls and unexpected calls?
-
-A **nice mock** suppresses uninteresting call *warnings*. It is less chatty than
-the default mock, but otherwise is the same. If a test fails with a default
-mock, it will also fail using a nice mock instead. And vice versa. Don't expect
-making a mock nice to change the test's result.
-
-A **strict mock** turns uninteresting call warnings into errors. So making a
-mock strict may change the test's result.
-
-Let's look at an example:
-
-```cpp
-TEST(...) {
-  NiceMock<MockDomainRegistry> mock_registry;
-  EXPECT_CALL(mock_registry, GetDomainOwner("google.com"))
-          .WillRepeatedly(Return("Larry Page"));
-
-  // Use mock_registry in code under test.
-  ... &mock_registry ...
-}
-```
-
-The sole `EXPECT_CALL` here says that all calls to `GetDomainOwner()` must have
-`"google.com"` as the argument. If `GetDomainOwner("yahoo.com")` is called, it
-will be an unexpected call, and thus an error. *Having a nice mock doesn't
-change the severity of an unexpected call.*
-
-So how do we tell gMock that `GetDomainOwner()` can be called with some other
-arguments as well? The standard technique is to add a "catch all" `EXPECT_CALL`:
-
-```cpp
-  EXPECT_CALL(mock_registry, GetDomainOwner(_))
-        .Times(AnyNumber());  // catches all other calls to this method.
-  EXPECT_CALL(mock_registry, GetDomainOwner("google.com"))
-        .WillRepeatedly(Return("Larry Page"));
-```
-
-Remember that `_` is the wildcard matcher that matches anything. With this, if
-`GetDomainOwner("google.com")` is called, it will do what the second
-`EXPECT_CALL` says; if it is called with a different argument, it will do what
-the first `EXPECT_CALL` says.
-
-Note that the order of the two `EXPECT_CALL`s is important, as a newer
-`EXPECT_CALL` takes precedence over an older one.
-
-For more on uninteresting calls, nice mocks, and strict mocks, read
-["The Nice, the Strict, and the Naggy"](#NiceStrictNaggy).
-
-### Ignoring Uninteresting Arguments {#ParameterlessExpectations}
-
-If your test doesn't care about the parameters (it only cares about the number
-or order of calls), you can often simply omit the parameter list:
-
-```cpp
-  // Expect foo.Bar( ... ) twice with any arguments.
-  EXPECT_CALL(foo, Bar).Times(2);
-
-  // Delegate to the given method whenever the factory is invoked.
-  ON_CALL(foo_factory, MakeFoo)
-      .WillByDefault(&BuildFooForTest);
-```
-
-This functionality is only available when a method is not overloaded; to prevent
-unexpected behavior it is a compilation error to try to set an expectation on a
-method where the specific overload is ambiguous. You can work around this by
-supplying a [simpler mock interface](#SimplerInterfaces) than the mocked class
-provides.
-
-This pattern is also useful when the arguments are interesting, but match logic
-is substantially complex. You can leave the argument list unspecified and use
-SaveArg actions to [save the values for later verification](#SaveArgVerify). If
-you do that, you can easily differentiate calling the method the wrong number of
-times from calling it with the wrong arguments.
-
-### Expecting Ordered Calls {#OrderedCalls}
-
-Although an `EXPECT_CALL()` statement defined earlier takes precedence when
-gMock tries to match a function call with an expectation, by default calls don't
-have to happen in the order `EXPECT_CALL()` statements are written. For example,
-if the arguments match the matchers in the third `EXPECT_CALL()`, but not those
-in the first two, then the third expectation will be used.
-
-If you would rather have all calls occur in the order of the expectations, put
-the `EXPECT_CALL()` statements in a block where you define a variable of type
-`InSequence`:
-
-```cpp
-using ::testing::_;
-using ::testing::InSequence;
-
-  {
-    InSequence s;
-
-    EXPECT_CALL(foo, DoThis(5));
-    EXPECT_CALL(bar, DoThat(_))
-        .Times(2);
-    EXPECT_CALL(foo, DoThis(6));
-  }
-```
-
-In this example, we expect a call to `foo.DoThis(5)`, followed by two calls to
-`bar.DoThat()` where the argument can be anything, which are in turn followed by
-a call to `foo.DoThis(6)`. If a call occurred out-of-order, gMock will report an
-error.
-
-### Expecting Partially Ordered Calls {#PartialOrder}
-
-Sometimes requiring everything to occur in a predetermined order can lead to
-brittle tests. For example, we may care about `A` occurring before both `B` and
-`C`, but aren't interested in the relative order of `B` and `C`. In this case,
-the test should reflect our real intent, instead of being overly constraining.
-
-gMock allows you to impose an arbitrary DAG (directed acyclic graph) on the
-calls. One way to express the DAG is to use the [After](#AfterClause) clause of
-`EXPECT_CALL`.
-
-Another way is via the `InSequence()` clause (not the same as the `InSequence`
-class), which we borrowed from jMock 2. It's less flexible than `After()`, but
-more convenient when you have long chains of sequential calls, as it doesn't
-require you to come up with different names for the expectations in the chains.
-Here's how it works:
-
-If we view `EXPECT_CALL()` statements as nodes in a graph, and add an edge from
-node A to node B wherever A must occur before B, we can get a DAG. We use the
-term "sequence" to mean a directed path in this DAG. Now, if we decompose the
-DAG into sequences, we just need to know which sequences each `EXPECT_CALL()`
-belongs to in order to be able to reconstruct the original DAG.
-
-So, to specify the partial order on the expectations we need to do two things:
-first to define some `Sequence` objects, and then for each `EXPECT_CALL()` say
-which `Sequence` objects it is part of.
-
-Expectations in the same sequence must occur in the order they are written. For
-example,
-
-```cpp
-using ::testing::Sequence;
-...
-  Sequence s1, s2;
-
-  EXPECT_CALL(foo, A())
-      .InSequence(s1, s2);
-  EXPECT_CALL(bar, B())
-      .InSequence(s1);
-  EXPECT_CALL(bar, C())
-      .InSequence(s2);
-  EXPECT_CALL(foo, D())
-      .InSequence(s2);
-```
-
-specifies the following DAG (where `s1` is `A -> B`, and `s2` is `A -> C -> D`):
-
-```text
-       +---> B
-       |
-  A ---|
-       |
-        +---> C ---> D
-```
-
-This means that A must occur before B and C, and C must occur before D. There's
-no restriction about the order other than these.
-
-### Controlling When an Expectation Retires
-
-When a mock method is called, gMock only considers expectations that are still
-active. An expectation is active when created, and becomes inactive (aka
-*retires*) when a call that has to occur later has occurred. For example, in
-
-```cpp
-using ::testing::_;
-using ::testing::Sequence;
-...
-  Sequence s1, s2;
-
-  EXPECT_CALL(log, Log(WARNING, _, "File too large."))      // #1
-      .Times(AnyNumber())
-      .InSequence(s1, s2);
-  EXPECT_CALL(log, Log(WARNING, _, "Data set is empty."))   // #2
-      .InSequence(s1);
-  EXPECT_CALL(log, Log(WARNING, _, "User not found."))      // #3
-      .InSequence(s2);
-```
-
-as soon as either #2 or #3 is matched, #1 will retire. If a warning `"File too
-large."` is logged after this, it will be an error.
-
-Note that an expectation doesn't retire automatically when it's saturated. For
-example,
-
-```cpp
-using ::testing::_;
-...
-  EXPECT_CALL(log, Log(WARNING, _, _));                     // #1
-  EXPECT_CALL(log, Log(WARNING, _, "File too large."));     // #2
-```
-
-says that there will be exactly one warning with the message `"File too
-large."`. If the second warning contains this message too, #2 will match again
-and result in an upper-bound-violated error.
-
-If this is not what you want, you can ask an expectation to retire as soon as it
-becomes saturated:
-
-```cpp
-using ::testing::_;
-...
-  EXPECT_CALL(log, Log(WARNING, _, _));                     // #1
-  EXPECT_CALL(log, Log(WARNING, _, "File too large."))      // #2
-      .RetiresOnSaturation();
-```
-
-Here #2 can be used only once, so if you have two warnings with the message
-`"File too large."`, the first will match #2 and the second will match #1 -
-there will be no error.
-
-## Using Actions
-
-### Returning References from Mock Methods
-
-If a mock function's return type is a reference, you need to use `ReturnRef()`
-instead of `Return()` to return a result:
-
-```cpp
-using ::testing::ReturnRef;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD(Bar&, GetBar, (), (override));
-};
-...
-  MockFoo foo;
-  Bar bar;
-  EXPECT_CALL(foo, GetBar())
-      .WillOnce(ReturnRef(bar));
-...
-```
-
-### Returning Live Values from Mock Methods
-
-The `Return(x)` action saves a copy of `x` when the action is created, and
-always returns the same value whenever it's executed. Sometimes you may want to
-instead return the *live* value of `x` (i.e. its value at the time when the
-action is *executed*.). Use either `ReturnRef()` or `ReturnPointee()` for this
-purpose.
-
-If the mock function's return type is a reference, you can do it using
-`ReturnRef(x)`, as shown in the previous recipe ("Returning References from Mock
-Methods"). However, gMock doesn't let you use `ReturnRef()` in a mock function
-whose return type is not a reference, as doing that usually indicates a user
-error. So, what shall you do?
-
-Though you may be tempted, DO NOT use `ByRef()`:
-
-```cpp
-using testing::ByRef;
-using testing::Return;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD(int, GetValue, (), (override));
-};
-...
-  int x = 0;
-  MockFoo foo;
-  EXPECT_CALL(foo, GetValue())
-      .WillRepeatedly(Return(ByRef(x)));  // Wrong!
-  x = 42;
-  EXPECT_EQ(42, foo.GetValue());
-```
-
-Unfortunately, it doesn't work here. The above code will fail with error:
-
-```text
-Value of: foo.GetValue()
-  Actual: 0
-Expected: 42
-```
-
-The reason is that `Return(*value*)` converts `value` to the actual return type
-of the mock function at the time when the action is *created*, not when it is
-*executed*. (This behavior was chosen for the action to be safe when `value` is
-a proxy object that references some temporary objects.) As a result, `ByRef(x)`
-is converted to an `int` value (instead of a `const int&`) when the expectation
-is set, and `Return(ByRef(x))` will always return 0.
-
-`ReturnPointee(pointer)` was provided to solve this problem specifically. It
-returns the value pointed to by `pointer` at the time the action is *executed*:
-
-```cpp
-using testing::ReturnPointee;
-...
-  int x = 0;
-  MockFoo foo;
-  EXPECT_CALL(foo, GetValue())
-      .WillRepeatedly(ReturnPointee(&x));  // Note the & here.
-  x = 42;
-  EXPECT_EQ(42, foo.GetValue());  // This will succeed now.
-```
-
-### Combining Actions
-
-Want to do more than one thing when a function is called? That's fine. `DoAll()`
-allow you to do sequence of actions every time. Only the return value of the
-last action in the sequence will be used.
-
-```cpp
-using ::testing::_;
-using ::testing::DoAll;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD(bool, Bar, (int n), (override));
-};
-...
-  EXPECT_CALL(foo, Bar(_))
-      .WillOnce(DoAll(action_1,
-                      action_2,
-                      ...
-                      action_n));
-```
-
-### Verifying Complex Arguments {#SaveArgVerify}
-
-If you want to verify that a method is called with a particular argument but the
-match criteria is complex, it can be difficult to distinguish between
-cardinality failures (calling the method the wrong number of times) and argument
-match failures. Similarly, if you are matching multiple parameters, it may not
-be easy to distinguishing which argument failed to match. For example:
-
-```cpp
-  // Not ideal: this could fail because of a problem with arg1 or arg2, or maybe
-  // just the method wasn't called.
-  EXPECT_CALL(foo, SendValues(_, ElementsAre(1, 4, 4, 7), EqualsProto( ... )));
-```
-
-You can instead save the arguments and test them individually:
-
-```cpp
-  EXPECT_CALL(foo, SendValues)
-      .WillOnce(DoAll(SaveArg<1>(&actual_array), SaveArg<2>(&actual_proto)));
-  ... run the test
-  EXPECT_THAT(actual_array, ElementsAre(1, 4, 4, 7));
-  EXPECT_THAT(actual_proto, EqualsProto( ... ));
-```
-
-### Mocking Side Effects {#MockingSideEffects}
-
-Sometimes a method exhibits its effect not via returning a value but via side
-effects. For example, it may change some global state or modify an output
-argument. To mock side effects, in general you can define your own action by
-implementing `::testing::ActionInterface`.
-
-If all you need to do is to change an output argument, the built-in
-`SetArgPointee()` action is convenient:
-
-```cpp
-using ::testing::_;
-using ::testing::SetArgPointee;
-
-class MockMutator : public Mutator {
- public:
-  MOCK_METHOD(void, Mutate, (bool mutate, int* value), (override));
-  ...
-}
-...
-  MockMutator mutator;
-  EXPECT_CALL(mutator, Mutate(true, _))
-      .WillOnce(SetArgPointee<1>(5));
-```
-
-In this example, when `mutator.Mutate()` is called, we will assign 5 to the
-`int` variable pointed to by argument #1 (0-based).
-
-`SetArgPointee()` conveniently makes an internal copy of the value you pass to
-it, removing the need to keep the value in scope and alive. The implication
-however is that the value must have a copy constructor and assignment operator.
-
-If the mock method also needs to return a value as well, you can chain
-`SetArgPointee()` with `Return()` using `DoAll()`, remembering to put the
-`Return()` statement last:
-
-```cpp
-using ::testing::_;
-using ::testing::Return;
-using ::testing::SetArgPointee;
-
-class MockMutator : public Mutator {
- public:
-  ...
-  MOCK_METHOD(bool, MutateInt, (int* value), (override));
-}
-...
-  MockMutator mutator;
-  EXPECT_CALL(mutator, MutateInt(_))
-      .WillOnce(DoAll(SetArgPointee<0>(5),
-                      Return(true)));
-```
-
-Note, however, that if you use the `ReturnOKWith()` method, it will override the
-values provided by `SetArgPointee()` in the response parameters of your function
-call.
-
-If the output argument is an array, use the `SetArrayArgument<N>(first, last)`
-action instead. It copies the elements in source range `[first, last)` to the
-array pointed to by the `N`-th (0-based) argument:
-
-```cpp
-using ::testing::NotNull;
-using ::testing::SetArrayArgument;
-
-class MockArrayMutator : public ArrayMutator {
- public:
-  MOCK_METHOD(void, Mutate, (int* values, int num_values), (override));
-  ...
-}
-...
-  MockArrayMutator mutator;
-  int values[5] = {1, 2, 3, 4, 5};
-  EXPECT_CALL(mutator, Mutate(NotNull(), 5))
-      .WillOnce(SetArrayArgument<0>(values, values + 5));
-```
-
-This also works when the argument is an output iterator:
-
-```cpp
-using ::testing::_;
-using ::testing::SetArrayArgument;
-
-class MockRolodex : public Rolodex {
- public:
-  MOCK_METHOD(void, GetNames, (std::back_insert_iterator<vector<string>>),
-              (override));
-  ...
-}
-...
-  MockRolodex rolodex;
-  vector<string> names;
-  names.push_back("George");
-  names.push_back("John");
-  names.push_back("Thomas");
-  EXPECT_CALL(rolodex, GetNames(_))
-      .WillOnce(SetArrayArgument<0>(names.begin(), names.end()));
-```
-
-### Changing a Mock Object's Behavior Based on the State
-
-If you expect a call to change the behavior of a mock object, you can use
-`::testing::InSequence` to specify different behaviors before and after the
-call:
-
-```cpp
-using ::testing::InSequence;
-using ::testing::Return;
-
-...
-  {
-     InSequence seq;
-     EXPECT_CALL(my_mock, IsDirty())
-         .WillRepeatedly(Return(true));
-     EXPECT_CALL(my_mock, Flush());
-     EXPECT_CALL(my_mock, IsDirty())
-         .WillRepeatedly(Return(false));
-  }
-  my_mock.FlushIfDirty();
-```
-
-This makes `my_mock.IsDirty()` return `true` before `my_mock.Flush()` is called
-and return `false` afterwards.
-
-If the behavior change is more complex, you can store the effects in a variable
-and make a mock method get its return value from that variable:
-
-```cpp
-using ::testing::_;
-using ::testing::SaveArg;
-using ::testing::Return;
-
-ACTION_P(ReturnPointee, p) { return *p; }
-...
-  int previous_value = 0;
-  EXPECT_CALL(my_mock, GetPrevValue)
-      .WillRepeatedly(ReturnPointee(&previous_value));
-  EXPECT_CALL(my_mock, UpdateValue)
-      .WillRepeatedly(SaveArg<0>(&previous_value));
-  my_mock.DoSomethingToUpdateValue();
-```
-
-Here `my_mock.GetPrevValue()` will always return the argument of the last
-`UpdateValue()` call.
-
-### Setting the Default Value for a Return Type {#DefaultValue}
-
-If a mock method's return type is a built-in C++ type or pointer, by default it
-will return 0 when invoked. Also, in C++ 11 and above, a mock method whose
-return type has a default constructor will return a default-constructed value by
-default. You only need to specify an action if this default value doesn't work
-for you.
-
-Sometimes, you may want to change this default value, or you may want to specify
-a default value for types gMock doesn't know about. You can do this using the
-`::testing::DefaultValue` class template:
-
-```cpp
-using ::testing::DefaultValue;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD(Bar, CalculateBar, (), (override));
-};
-
-
-...
-  Bar default_bar;
-  // Sets the default return value for type Bar.
-  DefaultValue<Bar>::Set(default_bar);
-
-  MockFoo foo;
-
-  // We don't need to specify an action here, as the default
-  // return value works for us.
-  EXPECT_CALL(foo, CalculateBar());
-
-  foo.CalculateBar();  // This should return default_bar.
-
-  // Unsets the default return value.
-  DefaultValue<Bar>::Clear();
-```
-
-Please note that changing the default value for a type can make you tests hard
-to understand. We recommend you to use this feature judiciously. For example,
-you may want to make sure the `Set()` and `Clear()` calls are right next to the
-code that uses your mock.
-
-### Setting the Default Actions for a Mock Method
-
-You've learned how to change the default value of a given type. However, this
-may be too coarse for your purpose: perhaps you have two mock methods with the
-same return type and you want them to have different behaviors. The `ON_CALL()`
-macro allows you to customize your mock's behavior at the method level:
-
-```cpp
-using ::testing::_;
-using ::testing::AnyNumber;
-using ::testing::Gt;
-using ::testing::Return;
-...
-  ON_CALL(foo, Sign(_))
-      .WillByDefault(Return(-1));
-  ON_CALL(foo, Sign(0))
-      .WillByDefault(Return(0));
-  ON_CALL(foo, Sign(Gt(0)))
-      .WillByDefault(Return(1));
-
-  EXPECT_CALL(foo, Sign(_))
-      .Times(AnyNumber());
-
-  foo.Sign(5);   // This should return 1.
-  foo.Sign(-9);  // This should return -1.
-  foo.Sign(0);   // This should return 0.
-```
-
-As you may have guessed, when there are more than one `ON_CALL()` statements,
-the newer ones in the order take precedence over the older ones. In other words,
-the **last** one that matches the function arguments will be used. This matching
-order allows you to set up the common behavior in a mock object's constructor or
-the test fixture's set-up phase and specialize the mock's behavior later.
-
-Note that both `ON_CALL` and `EXPECT_CALL` have the same "later statements take
-precedence" rule, but they don't interact. That is, `EXPECT_CALL`s have their
-own precedence order distinct from the `ON_CALL` precedence order.
-
-### Using Functions/Methods/Functors/Lambdas as Actions {#FunctionsAsActions}
-
-If the built-in actions don't suit you, you can use an existing callable
-(function, `std::function`, method, functor, lambda as an action.
-
-<!-- GOOGLETEST_CM0024 DO NOT DELETE -->
-
-```cpp
-using ::testing::_; using ::testing::Invoke;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD(int, Sum, (int x, int y), (override));
-  MOCK_METHOD(bool, ComplexJob, (int x), (override));
-};
-
-int CalculateSum(int x, int y) { return x + y; }
-int Sum3(int x, int y, int z) { return x + y + z; }
-
-class Helper {
- public:
-  bool ComplexJob(int x);
-};
-
-...
-  MockFoo foo;
-  Helper helper;
-  EXPECT_CALL(foo, Sum(_, _))
-      .WillOnce(&CalculateSum)
-      .WillRepeatedly(Invoke(NewPermanentCallback(Sum3, 1)));
-  EXPECT_CALL(foo, ComplexJob(_))
-      .WillOnce(Invoke(&helper, &Helper::ComplexJob));
-      .WillRepeatedly([](int x) { return x > 0; });
-
-  foo.Sum(5, 6);         // Invokes CalculateSum(5, 6).
-  foo.Sum(2, 3);         // Invokes Sum3(1, 2, 3).
-  foo.ComplexJob(10);    // Invokes helper.ComplexJob(10).
-  foo.ComplexJob(-1);    // Invokes the inline lambda.
-```
-
-The only requirement is that the type of the function, etc must be *compatible*
-with the signature of the mock function, meaning that the latter's arguments can
-be implicitly converted to the corresponding arguments of the former, and the
-former's return type can be implicitly converted to that of the latter. So, you
-can invoke something whose type is *not* exactly the same as the mock function,
-as long as it's safe to do so - nice, huh?
-
-**`Note:`{.escaped}**
-
-*   The action takes ownership of the callback and will delete it when the
-    action itself is destructed.
-*   If the type of a callback is derived from a base callback type `C`, you need
-    to implicitly cast it to `C` to resolve the overloading, e.g.
-
-    ```cpp
-    using ::testing::Invoke;
-    ...
-      ResultCallback<bool>* is_ok = ...;
-      ... Invoke(is_ok) ...;  // This works.
-
-      BlockingClosure* done = new BlockingClosure;
-      ... Invoke(implicit_cast<Closure*>(done)) ...;  // The cast is necessary.
-    ```
-
-### Using Functions with Extra Info as Actions
-
-The function or functor you call using `Invoke()` must have the same number of
-arguments as the mock function you use it for. Sometimes you may have a function
-that takes more arguments, and you are willing to pass in the extra arguments
-yourself to fill the gap. You can do this in gMock using callbacks with
-pre-bound arguments. Here's an example:
-
-```cpp
-using ::testing::Invoke;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD(char, DoThis, (int n), (override));
-};
-
-char SignOfSum(int x, int y) {
-  const int sum = x + y;
-  return (sum > 0) ? '+' : (sum < 0) ? '-' : '0';
-}
-
-TEST_F(FooTest, Test) {
-  MockFoo foo;
-
-  EXPECT_CALL(foo, DoThis(2))
-      .WillOnce(Invoke(NewPermanentCallback(SignOfSum, 5)));
-  EXPECT_EQ('+', foo.DoThis(2));  // Invokes SignOfSum(5, 2).
-}
-```
-
-### Invoking a Function/Method/Functor/Lambda/Callback Without Arguments
-
-`Invoke()` is very useful for doing actions that are more complex. It passes the
-mock function's arguments to the function, etc being invoked such that the
-callee has the full context of the call to work with. If the invoked function is
-not interested in some or all of the arguments, it can simply ignore them.
-
-Yet, a common pattern is that a test author wants to invoke a function without
-the arguments of the mock function. `Invoke()` allows her to do that using a
-wrapper function that throws away the arguments before invoking an underlining
-nullary function. Needless to say, this can be tedious and obscures the intent
-of the test.
-
-`InvokeWithoutArgs()` solves this problem. It's like `Invoke()` except that it
-doesn't pass the mock function's arguments to the callee. Here's an example:
-
-```cpp
-using ::testing::_;
-using ::testing::InvokeWithoutArgs;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD(bool, ComplexJob, (int n), (override));
-};
-
-bool Job1() { ... }
-bool Job2(int n, char c) { ... }
-
-...
-  MockFoo foo;
-  EXPECT_CALL(foo, ComplexJob(_))
-      .WillOnce(InvokeWithoutArgs(Job1))
-      .WillOnce(InvokeWithoutArgs(NewPermanentCallback(Job2, 5, 'a')));
-
-  foo.ComplexJob(10);  // Invokes Job1().
-  foo.ComplexJob(20);  // Invokes Job2(5, 'a').
-```
-
-**`Note:`{.escaped}**
-
-*   The action takes ownership of the callback and will delete it when the
-    action itself is destructed.
-*   If the type of a callback is derived from a base callback type `C`, you need
-    to implicitly cast it to `C` to resolve the overloading, e.g.
-
-    ```cpp
-    using ::testing::InvokeWithoutArgs;
-    ...
-      ResultCallback<bool>* is_ok = ...;
-      ... InvokeWithoutArgs(is_ok) ...;  // This works.
-
-      BlockingClosure* done = ...;
-      ... InvokeWithoutArgs(implicit_cast<Closure*>(done)) ...;
-      // The cast is necessary.
-    ```
-
-### Invoking an Argument of the Mock Function
-
-Sometimes a mock function will receive a function pointer, a functor (in other
-words, a "callable") as an argument, e.g.
-
-```cpp
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD(bool, DoThis, (int n, (ResultCallback1<bool, int>* callback)),
-              (override));
-};
-```
-
-and you may want to invoke this callable argument:
-
-```cpp
-using ::testing::_;
-...
-  MockFoo foo;
-  EXPECT_CALL(foo, DoThis(_, _))
-      .WillOnce(...);
-      // Will execute callback->Run(5), where callback is the
-      // second argument DoThis() receives.
-```
-
-NOTE: The section below is legacy documentation from before C++ had lambdas:
-
-Arghh, you need to refer to a mock function argument but C++ has no lambda
-(yet), so you have to define your own action. :-( Or do you really?
-
-Well, gMock has an action to solve *exactly* this problem:
-
-```cpp
-InvokeArgument<N>(arg_1, arg_2, ..., arg_m)
-```
-
-will invoke the `N`-th (0-based) argument the mock function receives, with
-`arg_1`, `arg_2`, ..., and `arg_m`. No matter if the argument is a function
-pointer, a functor, or a callback. gMock handles them all.
-
-With that, you could write:
-
-```cpp
-using ::testing::_;
-using ::testing::InvokeArgument;
-...
-  EXPECT_CALL(foo, DoThis(_, _))
-      .WillOnce(InvokeArgument<1>(5));
-      // Will execute callback->Run(5), where callback is the
-      // second argument DoThis() receives.
-```
-
-What if the callable takes an argument by reference? No problem - just wrap it
-inside `ByRef()`:
-
-```cpp
-  ...
-  MOCK_METHOD(bool, Bar,
-              ((ResultCallback2<bool, int, const Helper&>* callback)),
-              (override));
-  ...
-  using ::testing::_;
-  using ::testing::ByRef;
-  using ::testing::InvokeArgument;
-  ...
-  MockFoo foo;
-  Helper helper;
-  ...
-  EXPECT_CALL(foo, Bar(_))
-      .WillOnce(InvokeArgument<0>(5, ByRef(helper)));
-      // ByRef(helper) guarantees that a reference to helper, not a copy of it,
-      // will be passed to the callback.
-```
-
-What if the callable takes an argument by reference and we do **not** wrap the
-argument in `ByRef()`? Then `InvokeArgument()` will *make a copy* of the
-argument, and pass a *reference to the copy*, instead of a reference to the
-original value, to the callable. This is especially handy when the argument is a
-temporary value:
-
-```cpp
-  ...
-  MOCK_METHOD(bool, DoThat, (bool (*f)(const double& x, const string& s)),
-              (override));
-  ...
-  using ::testing::_;
-  using ::testing::InvokeArgument;
-  ...
-  MockFoo foo;
-  ...
-  EXPECT_CALL(foo, DoThat(_))
-      .WillOnce(InvokeArgument<0>(5.0, string("Hi")));
-      // Will execute (*f)(5.0, string("Hi")), where f is the function pointer
-      // DoThat() receives.  Note that the values 5.0 and string("Hi") are
-      // temporary and dead once the EXPECT_CALL() statement finishes.  Yet
-      // it's fine to perform this action later, since a copy of the values
-      // are kept inside the InvokeArgument action.
-```
-
-### Ignoring an Action's Result
-
-Sometimes you have an action that returns *something*, but you need an action
-that returns `void` (perhaps you want to use it in a mock function that returns
-`void`, or perhaps it needs to be used in `DoAll()` and it's not the last in the
-list). `IgnoreResult()` lets you do that. For example:
-
-```cpp
-using ::testing::_;
-using ::testing::DoAll;
-using ::testing::IgnoreResult;
-using ::testing::Return;
-
-int Process(const MyData& data);
-string DoSomething();
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD(void, Abc, (const MyData& data), (override));
-  MOCK_METHOD(bool, Xyz, (), (override));
-};
-
-  ...
-  MockFoo foo;
-  EXPECT_CALL(foo, Abc(_))
-      // .WillOnce(Invoke(Process));
-      // The above line won't compile as Process() returns int but Abc() needs
-      // to return void.
-      .WillOnce(IgnoreResult(Process));
-  EXPECT_CALL(foo, Xyz())
-      .WillOnce(DoAll(IgnoreResult(DoSomething),
-                      // Ignores the string DoSomething() returns.
-                      Return(true)));
-```
-
-Note that you **cannot** use `IgnoreResult()` on an action that already returns
-`void`. Doing so will lead to ugly compiler errors.
-
-### Selecting an Action's Arguments {#SelectingArgs}
-
-Say you have a mock function `Foo()` that takes seven arguments, and you have a
-custom action that you want to invoke when `Foo()` is called. Trouble is, the
-custom action only wants three arguments:
-
-```cpp
-using ::testing::_;
-using ::testing::Invoke;
-...
-  MOCK_METHOD(bool, Foo,
-              (bool visible, const string& name, int x, int y,
-               (const map<pair<int, int>>), double& weight, double min_weight,
-               double max_wight));
-...
-bool IsVisibleInQuadrant1(bool visible, int x, int y) {
-  return visible && x >= 0 && y >= 0;
-}
-...
-  EXPECT_CALL(mock, Foo)
-      .WillOnce(Invoke(IsVisibleInQuadrant1));  // Uh, won't compile. :-(
-```
-
-To please the compiler God, you need to define an "adaptor" that has the same
-signature as `Foo()` and calls the custom action with the right arguments:
-
-```cpp
-using ::testing::_;
-using ::testing::Invoke;
-...
-bool MyIsVisibleInQuadrant1(bool visible, const string& name, int x, int y,
-                            const map<pair<int, int>, double>& weight,
-                            double min_weight, double max_wight) {
-  return IsVisibleInQuadrant1(visible, x, y);
-}
-...
-  EXPECT_CALL(mock, Foo)
-      .WillOnce(Invoke(MyIsVisibleInQuadrant1));  // Now it works.
-```
-
-But isn't this awkward?
-
-gMock provides a generic *action adaptor*, so you can spend your time minding
-more important business than writing your own adaptors. Here's the syntax:
-
-```cpp
-WithArgs<N1, N2, ..., Nk>(action)
-```
-
-creates an action that passes the arguments of the mock function at the given
-indices (0-based) to the inner `action` and performs it. Using `WithArgs`, our
-original example can be written as:
-
-```cpp
-using ::testing::_;
-using ::testing::Invoke;
-using ::testing::WithArgs;
-...
-  EXPECT_CALL(mock, Foo)
-      .WillOnce(WithArgs<0, 2, 3>(Invoke(IsVisibleInQuadrant1)));  // No need to define your own adaptor.
-```
-
-For better readability, gMock also gives you:
-
-*   `WithoutArgs(action)` when the inner `action` takes *no* argument, and
-*   `WithArg<N>(action)` (no `s` after `Arg`) when the inner `action` takes
-    *one* argument.
-
-As you may have realized, `InvokeWithoutArgs(...)` is just syntactic sugar for
-`WithoutArgs(Invoke(...))`.
-
-Here are more tips:
-
-*   The inner action used in `WithArgs` and friends does not have to be
-    `Invoke()` -- it can be anything.
-*   You can repeat an argument in the argument list if necessary, e.g.
-    `WithArgs<2, 3, 3, 5>(...)`.
-*   You can change the order of the arguments, e.g. `WithArgs<3, 2, 1>(...)`.
-*   The types of the selected arguments do *not* have to match the signature of
-    the inner action exactly. It works as long as they can be implicitly
-    converted to the corresponding arguments of the inner action. For example,
-    if the 4-th argument of the mock function is an `int` and `my_action` takes
-    a `double`, `WithArg<4>(my_action)` will work.
-
-### Ignoring Arguments in Action Functions
-
-The [selecting-an-action's-arguments](#SelectingArgs) recipe showed us one way
-to make a mock function and an action with incompatible argument lists fit
-together. The downside is that wrapping the action in `WithArgs<...>()` can get
-tedious for people writing the tests.
-
-If you are defining a function (or method, functor, lambda, callback) to be used
-with `Invoke*()`, and you are not interested in some of its arguments, an
-alternative to `WithArgs` is to declare the uninteresting arguments as `Unused`.
-This makes the definition less cluttered and less fragile in case the types of
-the uninteresting arguments change. It could also increase the chance the action
-function can be reused. For example, given
-
-```cpp
- public:
-  MOCK_METHOD(double, Foo, double(const string& label, double x, double y),
-              (override));
-  MOCK_METHOD(double, Bar, (int index, double x, double y), (override));
-```
-
-instead of
-
-```cpp
-using ::testing::_;
-using ::testing::Invoke;
-
-double DistanceToOriginWithLabel(const string& label, double x, double y) {
-  return sqrt(x*x + y*y);
-}
-double DistanceToOriginWithIndex(int index, double x, double y) {
-  return sqrt(x*x + y*y);
-}
-...
-  EXPECT_CALL(mock, Foo("abc", _, _))
-      .WillOnce(Invoke(DistanceToOriginWithLabel));
-  EXPECT_CALL(mock, Bar(5, _, _))
-      .WillOnce(Invoke(DistanceToOriginWithIndex));
-```
-
-you could write
-
-```cpp
-using ::testing::_;
-using ::testing::Invoke;
-using ::testing::Unused;
-
-double DistanceToOrigin(Unused, double x, double y) {
-  return sqrt(x*x + y*y);
-}
-...
-  EXPECT_CALL(mock, Foo("abc", _, _))
-      .WillOnce(Invoke(DistanceToOrigin));
-  EXPECT_CALL(mock, Bar(5, _, _))
-      .WillOnce(Invoke(DistanceToOrigin));
-```
-
-### Sharing Actions
-
-Just like matchers, a gMock action object consists of a pointer to a ref-counted
-implementation object. Therefore copying actions is also allowed and very
-efficient. When the last action that references the implementation object dies,
-the implementation object will be deleted.
-
-If you have some complex action that you want to use again and again, you may
-not have to build it from scratch everytime. If the action doesn't have an
-internal state (i.e. if it always does the same thing no matter how many times
-it has been called), you can assign it to an action variable and use that
-variable repeatedly. For example:
-
-```cpp
-using ::testing::Action;
-using ::testing::DoAll;
-using ::testing::Return;
-using ::testing::SetArgPointee;
-...
-  Action<bool(int*)> set_flag = DoAll(SetArgPointee<0>(5),
-                                      Return(true));
-  ... use set_flag in .WillOnce() and .WillRepeatedly() ...
-```
-
-However, if the action has its own state, you may be surprised if you share the
-action object. Suppose you have an action factory `IncrementCounter(init)` which
-creates an action that increments and returns a counter whose initial value is
-`init`, using two actions created from the same expression and using a shared
-action will exhibit different behaviors. Example:
-
-```cpp
-  EXPECT_CALL(foo, DoThis())
-      .WillRepeatedly(IncrementCounter(0));
-  EXPECT_CALL(foo, DoThat())
-      .WillRepeatedly(IncrementCounter(0));
-  foo.DoThis();  // Returns 1.
-  foo.DoThis();  // Returns 2.
-  foo.DoThat();  // Returns 1 - Blah() uses a different
-                 // counter than Bar()'s.
-```
-
-versus
-
-```cpp
-using ::testing::Action;
-...
-  Action<int()> increment = IncrementCounter(0);
-  EXPECT_CALL(foo, DoThis())
-      .WillRepeatedly(increment);
-  EXPECT_CALL(foo, DoThat())
-      .WillRepeatedly(increment);
-  foo.DoThis();  // Returns 1.
-  foo.DoThis();  // Returns 2.
-  foo.DoThat();  // Returns 3 - the counter is shared.
-```
-
-### Testing Asynchronous Behavior
-
-One oft-encountered problem with gMock is that it can be hard to test
-asynchronous behavior. Suppose you had a `EventQueue` class that you wanted to
-test, and you created a separate `EventDispatcher` interface so that you could
-easily mock it out. However, the implementation of the class fired all the
-events on a background thread, which made test timings difficult. You could just
-insert `sleep()` statements and hope for the best, but that makes your test
-behavior nondeterministic. A better way is to use gMock actions and
-`Notification` objects to force your asynchronous test to behave synchronously.
-
-```cpp
-using ::testing::DoAll;
-using ::testing::InvokeWithoutArgs;
-using ::testing::Return;
-
-class MockEventDispatcher : public EventDispatcher {
-  MOCK_METHOD(bool, DispatchEvent, (int32), (override));
-};
-
-ACTION_P(Notify, notification) {
-  notification->Notify();
-}
-
-TEST(EventQueueTest, EnqueueEventTest) {
-  MockEventDispatcher mock_event_dispatcher;
-  EventQueue event_queue(&mock_event_dispatcher);
-
-  const int32 kEventId = 321;
-  Notification done;
-  EXPECT_CALL(mock_event_dispatcher, DispatchEvent(kEventId))
-      .WillOnce(Notify(&done));
-
-  event_queue.EnqueueEvent(kEventId);
-  done.WaitForNotification();
-}
-```
-
-In the example above, we set our normal gMock expectations, but then add an
-additional action to notify the `Notification` object. Now we can just call
-`Notification::WaitForNotification()` in the main thread to wait for the
-asynchronous call to finish. After that, our test suite is complete and we can
-safely exit.
-
-Note: this example has a downside: namely, if the expectation is not satisfied,
-our test will run forever. It will eventually time-out and fail, but it will
-take longer and be slightly harder to debug. To alleviate this problem, you can
-use `WaitForNotificationWithTimeout(ms)` instead of `WaitForNotification()`.

-## Misc Recipes on Using gMock
-
-### Mocking Methods That Use Move-Only Types
-
-C++11 introduced *move-only types*. A move-only-typed value can be moved from
-one object to another, but cannot be copied. `std::unique_ptr<T>` is probably
-the most commonly used move-only type.
-
-Mocking a method that takes and/or returns move-only types presents some
-challenges, but nothing insurmountable. This recipe shows you how you can do it.
-Note that the support for move-only method arguments was only introduced to
-gMock in April 2017; in older code, you may find more complex
-[workarounds](#LegacyMoveOnly) for lack of this feature.
-
-Let’s say we are working on a fictional project that lets one post and share
-snippets called “buzzes”. Your code uses these types:
-
-```cpp
-enum class AccessLevel { kInternal, kPublic };
-
-class Buzz {
- public:
-  explicit Buzz(AccessLevel access) { ... }
-  ...
-};
-
-class Buzzer {
- public:
-  virtual ~Buzzer() {}
-  virtual std::unique_ptr<Buzz> MakeBuzz(StringPiece text) = 0;
-  virtual bool ShareBuzz(std::unique_ptr<Buzz> buzz, int64_t timestamp) = 0;
-  ...
-};
-```
-
-A `Buzz` object represents a snippet being posted. A class that implements the
-`Buzzer` interface is capable of creating and sharing `Buzz`es. Methods in
-`Buzzer` may return a `unique_ptr<Buzz>` or take a `unique_ptr<Buzz>`. Now we
-need to mock `Buzzer` in our tests.
-
-To mock a method that accepts or returns move-only types, you just use the
-familiar `MOCK_METHOD` syntax as usual:
-
-```cpp
-class MockBuzzer : public Buzzer {
- public:
-  MOCK_METHOD(std::unique_ptr<Buzz>, MakeBuzz, (StringPiece text), (override));
-  MOCK_METHOD(bool, ShareBuzz, (std::unique_ptr<Buzz> buzz, int64_t timestamp),
-              (override));
-};
-```
-
-Now that we have the mock class defined, we can use it in tests. In the
-following code examples, we assume that we have defined a `MockBuzzer` object
-named `mock_buzzer_`:
-
-```cpp
-  MockBuzzer mock_buzzer_;
-```
-
-First let’s see how we can set expectations on the `MakeBuzz()` method, which
-returns a `unique_ptr<Buzz>`.
-
-As usual, if you set an expectation without an action (i.e. the `.WillOnce()` or
-`.WillRepeatedly()` clause), when that expectation fires, the default action for
-that method will be taken. Since `unique_ptr<>` has a default constructor that
-returns a null `unique_ptr`, that’s what you’ll get if you don’t specify an
-action:
-
-```cpp
-  // Use the default action.
-  EXPECT_CALL(mock_buzzer_, MakeBuzz("hello"));
-
-  // Triggers the previous EXPECT_CALL.
-  EXPECT_EQ(nullptr, mock_buzzer_.MakeBuzz("hello"));
-```
-
-If you are not happy with the default action, you can tweak it as usual; see
-[Setting Default Actions](#OnCall).
-
-If you just need to return a pre-defined move-only value, you can use the
-`Return(ByMove(...))` action:
-
-```cpp
-  // When this fires, the unique_ptr<> specified by ByMove(...) will
-  // be returned.
-  EXPECT_CALL(mock_buzzer_, MakeBuzz("world"))
-      .WillOnce(Return(ByMove(MakeUnique<Buzz>(AccessLevel::kInternal))));
-
-  EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("world"));
-```
-
-Note that `ByMove()` is essential here - if you drop it, the code won’t compile.
-
-Quiz time! What do you think will happen if a `Return(ByMove(...))` action is
-performed more than once (e.g. you write `...
-.WillRepeatedly(Return(ByMove(...)));`)? Come think of it, after the first time
-the action runs, the source value will be consumed (since it’s a move-only
-value), so the next time around, there’s no value to move from -- you’ll get a
-run-time error that `Return(ByMove(...))` can only be run once.
-
-If you need your mock method to do more than just moving a pre-defined value,
-remember that you can always use a lambda or a callable object, which can do
-pretty much anything you want:
-
-```cpp
-  EXPECT_CALL(mock_buzzer_, MakeBuzz("x"))
-      .WillRepeatedly([](StringPiece text) {
-        return MakeUnique<Buzz>(AccessLevel::kInternal);
-      });
-
-  EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("x"));
-  EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("x"));
-```
-
-Every time this `EXPECT_CALL` fires, a new `unique_ptr<Buzz>` will be created
-and returned. You cannot do this with `Return(ByMove(...))`.
-
-That covers returning move-only values; but how do we work with methods
-accepting move-only arguments? The answer is that they work normally, although
-some actions will not compile when any of method's arguments are move-only. You
-can always use `Return`, or a [lambda or functor](#FunctionsAsActions):
-
-```cpp
-  using ::testing::Unused;
-
-  EXPECT_CALL(mock_buzzer_, ShareBuzz(NotNull(), _)).WillOnce(Return(true));
-  EXPECT_TRUE(mock_buzzer_.ShareBuzz(MakeUnique<Buzz>(AccessLevel::kInternal)),
-              0);
-
-  EXPECT_CALL(mock_buzzer_, ShareBuzz(_, _)).WillOnce(
-      [](std::unique_ptr<Buzz> buzz, Unused) { return buzz != nullptr; });
-  EXPECT_FALSE(mock_buzzer_.ShareBuzz(nullptr, 0));
-```
-
-Many built-in actions (`WithArgs`, `WithoutArgs`,`DeleteArg`, `SaveArg`, ...)
-could in principle support move-only arguments, but the support for this is not
-implemented yet. If this is blocking you, please file a bug.
-
-A few actions (e.g. `DoAll`) copy their arguments internally, so they can never
-work with non-copyable objects; you'll have to use functors instead.
-
-#### Legacy workarounds for move-only types {#LegacyMoveOnly}
-
-Support for move-only function arguments was only introduced to gMock in April
-2017. In older code, you may encounter the following workaround for the lack of
-this feature (it is no longer necessary - we're including it just for
-reference):
-
-```cpp
-class MockBuzzer : public Buzzer {
- public:
-  MOCK_METHOD(bool, DoShareBuzz, (Buzz* buzz, Time timestamp));
-  bool ShareBuzz(std::unique_ptr<Buzz> buzz, Time timestamp) override {
-    return DoShareBuzz(buzz.get(), timestamp);
-  }
-};
-```
-
-The trick is to delegate the `ShareBuzz()` method to a mock method (let’s call
-it `DoShareBuzz()`) that does not take move-only parameters. Then, instead of
-setting expectations on `ShareBuzz()`, you set them on the `DoShareBuzz()` mock
-method:
-
-```cpp
-  MockBuzzer mock_buzzer_;
-  EXPECT_CALL(mock_buzzer_, DoShareBuzz(NotNull(), _));
-
-  // When one calls ShareBuzz() on the MockBuzzer like this, the call is
-  // forwarded to DoShareBuzz(), which is mocked.  Therefore this statement
-  // will trigger the above EXPECT_CALL.
-  mock_buzzer_.ShareBuzz(MakeUnique<Buzz>(AccessLevel::kInternal), 0);
-```
-
-### Making the Compilation Faster
-
-Believe it or not, the *vast majority* of the time spent on compiling a mock
-class is in generating its constructor and destructor, as they perform
-non-trivial tasks (e.g. verification of the expectations). What's more, mock
-methods with different signatures have different types and thus their
-constructors/destructors need to be generated by the compiler separately. As a
-result, if you mock many different types of methods, compiling your mock class
-can get really slow.
-
-If you are experiencing slow compilation, you can move the definition of your
-mock class' constructor and destructor out of the class body and into a `.cc`
-file. This way, even if you `#include` your mock class in N files, the compiler
-only needs to generate its constructor and destructor once, resulting in a much
-faster compilation.
-
-Let's illustrate the idea using an example. Here's the definition of a mock
-class before applying this recipe:
-
-```cpp
-// File mock_foo.h.
-...
-class MockFoo : public Foo {
- public:
-  // Since we don't declare the constructor or the destructor,
-  // the compiler will generate them in every translation unit
-  // where this mock class is used.
-
-  MOCK_METHOD(int, DoThis, (), (override));
-  MOCK_METHOD(bool, DoThat, (const char* str), (override));
-  ... more mock methods ...
-};
-```
-
-After the change, it would look like:
-
-```cpp
-// File mock_foo.h.
-...
-class MockFoo : public Foo {
- public:
-  // The constructor and destructor are declared, but not defined, here.
-  MockFoo();
-  virtual ~MockFoo();
-
-  MOCK_METHOD(int, DoThis, (), (override));
-  MOCK_METHOD(bool, DoThat, (const char* str), (override));
-  ... more mock methods ...
-};
-```
-
-and
-
-```cpp
-// File mock_foo.cc.
-#include "path/to/mock_foo.h"
-
-// The definitions may appear trivial, but the functions actually do a
-// lot of things through the constructors/destructors of the member
-// variables used to implement the mock methods.
-MockFoo::MockFoo() {}
-MockFoo::~MockFoo() {}
-```
-
-### Forcing a Verification
-
-When it's being destroyed, your friendly mock object will automatically verify
-that all expectations on it have been satisfied, and will generate googletest
-failures if not. This is convenient as it leaves you with one less thing to
-worry about. That is, unless you are not sure if your mock object will be
-destroyed.
-
-How could it be that your mock object won't eventually be destroyed? Well, it
-might be created on the heap and owned by the code you are testing. Suppose
-there's a bug in that code and it doesn't delete the mock object properly - you
-could end up with a passing test when there's actually a bug.
-
-Using a heap checker is a good idea and can alleviate the concern, but its
-implementation is not 100% reliable. So, sometimes you do want to *force* gMock
-to verify a mock object before it is (hopefully) destructed. You can do this
-with `Mock::VerifyAndClearExpectations(&mock_object)`:
-
-```cpp
-TEST(MyServerTest, ProcessesRequest) {
-  using ::testing::Mock;
-
-  MockFoo* const foo = new MockFoo;
-  EXPECT_CALL(*foo, ...)...;
-  // ... other expectations ...
-
-  // server now owns foo.
-  MyServer server(foo);
-  server.ProcessRequest(...);
-
-  // In case that server's destructor will forget to delete foo,
-  // this will verify the expectations anyway.
-  Mock::VerifyAndClearExpectations(foo);
-}  // server is destroyed when it goes out of scope here.
-```
-
-**Tip:** The `Mock::VerifyAndClearExpectations()` function returns a `bool` to
-indicate whether the verification was successful (`true` for yes), so you can
-wrap that function call inside a `ASSERT_TRUE()` if there is no point going
-further when the verification has failed.
-
-### Using Check Points {#UsingCheckPoints}
-
-Sometimes you may want to "reset" a mock object at various check points in your
-test: at each check point, you verify that all existing expectations on the mock
-object have been satisfied, and then you set some new expectations on it as if
-it's newly created. This allows you to work with a mock object in "phases" whose
-sizes are each manageable.
-
-One such scenario is that in your test's `SetUp()` function, you may want to put
-the object you are testing into a certain state, with the help from a mock
-object. Once in the desired state, you want to clear all expectations on the
-mock, such that in the `TEST_F` body you can set fresh expectations on it.
-
-As you may have figured out, the `Mock::VerifyAndClearExpectations()` function
-we saw in the previous recipe can help you here. Or, if you are using
-`ON_CALL()` to set default actions on the mock object and want to clear the
-default actions as well, use `Mock::VerifyAndClear(&mock_object)` instead. This
-function does what `Mock::VerifyAndClearExpectations(&mock_object)` does and
-returns the same `bool`, **plus** it clears the `ON_CALL()` statements on
-`mock_object` too.
-
-Another trick you can use to achieve the same effect is to put the expectations
-in sequences and insert calls to a dummy "check-point" function at specific
-places. Then you can verify that the mock function calls do happen at the right
-time. For example, if you are exercising code:
-
-```cpp
-  Foo(1);
-  Foo(2);
-  Foo(3);
-```
-
-and want to verify that `Foo(1)` and `Foo(3)` both invoke `mock.Bar("a")`, but
-`Foo(2)` doesn't invoke anything. You can write:
-
-```cpp
-using ::testing::MockFunction;
-
-TEST(FooTest, InvokesBarCorrectly) {
-  MyMock mock;
-  // Class MockFunction<F> has exactly one mock method.  It is named
-  // Call() and has type F.
-  MockFunction<void(string check_point_name)> check;
-  {
-    InSequence s;
-
-    EXPECT_CALL(mock, Bar("a"));
-    EXPECT_CALL(check, Call("1"));
-    EXPECT_CALL(check, Call("2"));
-    EXPECT_CALL(mock, Bar("a"));
-  }
-  Foo(1);
-  check.Call("1");
-  Foo(2);
-  check.Call("2");
-  Foo(3);
-}
-```
-
-The expectation spec says that the first `Bar("a")` must happen before check
-point "1", the second `Bar("a")` must happen after check point "2", and nothing
-should happen between the two check points. The explicit check points make it
-easy to tell which `Bar("a")` is called by which call to `Foo()`.
-
-### Mocking Destructors
-
-Sometimes you want to make sure a mock object is destructed at the right time,
-e.g. after `bar->A()` is called but before `bar->B()` is called. We already know
-that you can specify constraints on the [order](#OrderedCalls) of mock function
-calls, so all we need to do is to mock the destructor of the mock function.
-
-This sounds simple, except for one problem: a destructor is a special function
-with special syntax and special semantics, and the `MOCK_METHOD` macro doesn't
-work for it:
-
-```cpp
-MOCK_METHOD(void, ~MockFoo, ());  // Won't compile!
-```
-
-The good news is that you can use a simple pattern to achieve the same effect.
-First, add a mock function `Die()` to your mock class and call it in the
-destructor, like this:
-
-```cpp
-class MockFoo : public Foo {
-  ...
-  // Add the following two lines to the mock class.
-  MOCK_METHOD(void, Die, ());
-  virtual ~MockFoo() { Die(); }
-};
-```
-
-(If the name `Die()` clashes with an existing symbol, choose another name.) Now,
-we have translated the problem of testing when a `MockFoo` object dies to
-testing when its `Die()` method is called:
-
-```cpp
-  MockFoo* foo = new MockFoo;
-  MockBar* bar = new MockBar;
-  ...
-  {
-    InSequence s;
-
-    // Expects *foo to die after bar->A() and before bar->B().
-    EXPECT_CALL(*bar, A());
-    EXPECT_CALL(*foo, Die());
-    EXPECT_CALL(*bar, B());
-  }
-```
-
-And that's that.
-
-### Using gMock and Threads {#UsingThreads}
-
-In a **unit** test, it's best if you could isolate and test a piece of code in a
-single-threaded context. That avoids race conditions and dead locks, and makes
-debugging your test much easier.
-
-Yet most programs are multi-threaded, and sometimes to test something we need to
-pound on it from more than one thread. gMock works for this purpose too.
-
-Remember the steps for using a mock:
-
-1.  Create a mock object `foo`.
-2.  Set its default actions and expectations using `ON_CALL()` and
-    `EXPECT_CALL()`.
-3.  The code under test calls methods of `foo`.
-4.  Optionally, verify and reset the mock.
-5.  Destroy the mock yourself, or let the code under test destroy it. The
-    destructor will automatically verify it.
-
-If you follow the following simple rules, your mocks and threads can live
-happily together:
-
-*   Execute your *test code* (as opposed to the code being tested) in *one*
-    thread. This makes your test easy to follow.
-*   Obviously, you can do step #1 without locking.
-*   When doing step #2 and #5, make sure no other thread is accessing `foo`.
-    Obvious too, huh?
-*   #3 and #4 can be done either in one thread or in multiple threads - anyway
-    you want. gMock takes care of the locking, so you don't have to do any -
-    unless required by your test logic.
-
-If you violate the rules (for example, if you set expectations on a mock while
-another thread is calling its methods), you get undefined behavior. That's not
-fun, so don't do it.
-
-gMock guarantees that the action for a mock function is done in the same thread
-that called the mock function. For example, in
-
-```cpp
-  EXPECT_CALL(mock, Foo(1))
-      .WillOnce(action1);
-  EXPECT_CALL(mock, Foo(2))
-      .WillOnce(action2);
-```
-
-if `Foo(1)` is called in thread 1 and `Foo(2)` is called in thread 2, gMock will
-execute `action1` in thread 1 and `action2` in thread 2.
-
-gMock does *not* impose a sequence on actions performed in different threads
-(doing so may create deadlocks as the actions may need to cooperate). This means
-that the execution of `action1` and `action2` in the above example *may*
-interleave. If this is a problem, you should add proper synchronization logic to
-`action1` and `action2` to make the test thread-safe.
-
-Also, remember that `DefaultValue<T>` is a global resource that potentially
-affects *all* living mock objects in your program. Naturally, you won't want to
-mess with it from multiple threads or when there still are mocks in action.
-
-### Controlling How Much Information gMock Prints
-
-When gMock sees something that has the potential of being an error (e.g. a mock
-function with no expectation is called, a.k.a. an uninteresting call, which is
-allowed but perhaps you forgot to explicitly ban the call), it prints some
-warning messages, including the arguments of the function, the return value, and
-the stack trace. Hopefully this will remind you to take a look and see if there
-is indeed a problem.
-
-Sometimes you are confident that your tests are correct and may not appreciate
-such friendly messages. Some other times, you are debugging your tests or
-learning about the behavior of the code you are testing, and wish you could
-observe every mock call that happens (including argument values, the return
-value, and the stack trace). Clearly, one size doesn't fit all.
-
-You can control how much gMock tells you using the `--gmock_verbose=LEVEL`
-command-line flag, where `LEVEL` is a string with three possible values:
-
-*   `info`: gMock will print all informational messages, warnings, and errors
-    (most verbose). At this setting, gMock will also log any calls to the
-    `ON_CALL/EXPECT_CALL` macros. It will include a stack trace in
-    "uninteresting call" warnings.
-*   `warning`: gMock will print both warnings and errors (less verbose); it will
-    omit the stack traces in "uninteresting call" warnings. This is the default.
-*   `error`: gMock will print errors only (least verbose).
-
-Alternatively, you can adjust the value of that flag from within your tests like
-so:
-
-```cpp
-  ::testing::FLAGS_gmock_verbose = "error";
-```
-
-If you find gMock printing too many stack frames with its informational or
-warning messages, remember that you can control their amount with the
-`--gtest_stack_trace_depth=max_depth` flag.
-
-Now, judiciously use the right flag to enable gMock serve you better!
-
-### Gaining Super Vision into Mock Calls
-
-You have a test using gMock. It fails: gMock tells you some expectations aren't
-satisfied. However, you aren't sure why: Is there a typo somewhere in the
-matchers? Did you mess up the order of the `EXPECT_CALL`s? Or is the code under
-test doing something wrong? How can you find out the cause?
-
-Won't it be nice if you have X-ray vision and can actually see the trace of all
-`EXPECT_CALL`s and mock method calls as they are made? For each call, would you
-like to see its actual argument values and which `EXPECT_CALL` gMock thinks it
-matches? If you still need some help to figure out who made these calls, how
-about being able to see the complete stack trace at each mock call?
-
-You can unlock this power by running your test with the `--gmock_verbose=info`
-flag. For example, given the test program:
-
-```cpp
-#include "gmock/gmock.h"
-
-using testing::_;
-using testing::HasSubstr;
-using testing::Return;
-
-class MockFoo {
- public:
-  MOCK_METHOD(void, F, (const string& x, const string& y));
-};
-
-TEST(Foo, Bar) {
-  MockFoo mock;
-  EXPECT_CALL(mock, F(_, _)).WillRepeatedly(Return());
-  EXPECT_CALL(mock, F("a", "b"));
-  EXPECT_CALL(mock, F("c", HasSubstr("d")));
-
-  mock.F("a", "good");
-  mock.F("a", "b");
-}
-```
-
-if you run it with `--gmock_verbose=info`, you will see this output:
-
-```shell
-[ RUN       ] Foo.Bar
-
-foo_test.cc:14: EXPECT_CALL(mock, F(_, _)) invoked
-Stack trace: ...
-
-foo_test.cc:15: EXPECT_CALL(mock, F("a", "b")) invoked
-Stack trace: ...
-
-foo_test.cc:16: EXPECT_CALL(mock, F("c", HasSubstr("d"))) invoked
-Stack trace: ...
-
-foo_test.cc:14: Mock function call matches EXPECT_CALL(mock, F(_, _))...
-    Function call: F(@0x7fff7c8dad40"a",@0x7fff7c8dad10"good")
-Stack trace: ...
-
-foo_test.cc:15: Mock function call matches EXPECT_CALL(mock, F("a", "b"))...
-    Function call: F(@0x7fff7c8dada0"a",@0x7fff7c8dad70"b")
-Stack trace: ...
-
-foo_test.cc:16: Failure
-Actual function call count doesn't match EXPECT_CALL(mock, F("c", HasSubstr("d")))...
-         Expected: to be called once
-           Actual: never called - unsatisfied and active
-[  FAILED  ] Foo.Bar
-```
-
-Suppose the bug is that the `"c"` in the third `EXPECT_CALL` is a typo and
-should actually be `"a"`. With the above message, you should see that the actual
-`F("a", "good")` call is matched by the first `EXPECT_CALL`, not the third as
-you thought. From that it should be obvious that the third `EXPECT_CALL` is
-written wrong. Case solved.
-
-If you are interested in the mock call trace but not the stack traces, you can
-combine `--gmock_verbose=info` with `--gtest_stack_trace_depth=0` on the test
-command line.

-
-### Running Tests in Emacs
-
-If you build and run your tests in Emacs using the `M-x google-compile` command
-(as many googletest users do), the source file locations of gMock and googletest
-errors will be highlighted. Just press `<Enter>` on one of them and you'll be
-taken to the offending line. Or, you can just type `C-x`` to jump to the next
-error.
-
-To make it even easier, you can add the following lines to your `~/.emacs` file:
-
-```text
-(global-set-key "\M-m"  'google-compile)  ; m is for make
-(global-set-key [M-down] 'next-error)
-(global-set-key [M-up]  '(lambda () (interactive) (next-error -1)))
-```
-
-Then you can type `M-m` to start a build (if you want to run the test as well,
-just make sure `foo_test.run` or `runtests` is in the build command you supply
-after typing `M-m`), or `M-up`/`M-down` to move back and forth between errors.
-
-## Extending gMock
-
-### Writing New Matchers Quickly {#NewMatchers}
-
-WARNING: gMock does not guarantee when or how many times a matcher will be
-invoked. Therefore, all matchers must be functionally pure. See
-[this section](#PureMatchers) for more details.
-
-The `MATCHER*` family of macros can be used to define custom matchers easily.
-The syntax:
-
-```cpp
-MATCHER(name, description_string_expression) { statements; }
-```
-
-will define a matcher with the given name that executes the statements, which
-must return a `bool` to indicate if the match succeeds. Inside the statements,
-you can refer to the value being matched by `arg`, and refer to its type by
-`arg_type`.
-
-The *description string* is a `string`-typed expression that documents what the
-matcher does, and is used to generate the failure message when the match fails.
-It can (and should) reference the special `bool` variable `negation`, and should
-evaluate to the description of the matcher when `negation` is `false`, or that
-of the matcher's negation when `negation` is `true`.
-
-For convenience, we allow the description string to be empty (`""`), in which
-case gMock will use the sequence of words in the matcher name as the
-description.
-
-For example:
-
-```cpp
-MATCHER(IsDivisibleBy7, "") { return (arg % 7) == 0; }
-```
-
-allows you to write
-
-```cpp
-  // Expects mock_foo.Bar(n) to be called where n is divisible by 7.
-  EXPECT_CALL(mock_foo, Bar(IsDivisibleBy7()));
-```
-
-or,
-
-```cpp
-  using ::testing::Not;
-  ...
-  // Verifies that two values are divisible by 7.
-  EXPECT_THAT(some_expression, IsDivisibleBy7());
-  EXPECT_THAT(some_other_expression, Not(IsDivisibleBy7()));
-```
-
-If the above assertions fail, they will print something like:
-
-```shell
-  Value of: some_expression
-  Expected: is divisible by 7
-    Actual: 27
-  ...
-  Value of: some_other_expression
-  Expected: not (is divisible by 7)
-    Actual: 21
-```
-
-where the descriptions `"is divisible by 7"` and `"not (is divisible by 7)"` are
-automatically calculated from the matcher name `IsDivisibleBy7`.
-
-As you may have noticed, the auto-generated descriptions (especially those for
-the negation) may not be so great. You can always override them with a `string`
-expression of your own:
-
-```cpp
-MATCHER(IsDivisibleBy7,
-        absl::StrCat(negation ? "isn't" : "is", " divisible by 7")) {
-  return (arg % 7) == 0;
-}
-```
-
-Optionally, you can stream additional information to a hidden argument named
-`result_listener` to explain the match result. For example, a better definition
-of `IsDivisibleBy7` is:
-
-```cpp
-MATCHER(IsDivisibleBy7, "") {
-  if ((arg % 7) == 0)
-    return true;
-
-  *result_listener << "the remainder is " << (arg % 7);
-  return false;
-}
-```
-
-With this definition, the above assertion will give a better message:
-
-```shell
-  Value of: some_expression
-  Expected: is divisible by 7
-    Actual: 27 (the remainder is 6)
-```
-
-You should let `MatchAndExplain()` print *any additional information* that can
-help a user understand the match result. Note that it should explain why the
-match succeeds in case of a success (unless it's obvious) - this is useful when
-the matcher is used inside `Not()`. There is no need to print the argument value
-itself, as gMock already prints it for you.
-
-NOTE: The type of the value being matched (`arg_type`) is determined by the
-context in which you use the matcher and is supplied to you by the compiler, so
-you don't need to worry about declaring it (nor can you). This allows the
-matcher to be polymorphic. For example, `IsDivisibleBy7()` can be used to match
-any type where the value of `(arg % 7) == 0` can be implicitly converted to a
-`bool`. In the `Bar(IsDivisibleBy7())` example above, if method `Bar()` takes an
-`int`, `arg_type` will be `int`; if it takes an `unsigned long`, `arg_type` will
-be `unsigned long`; and so on.
-
-### Writing New Parameterized Matchers Quickly
-
-Sometimes you'll want to define a matcher that has parameters. For that you can
-use the macro:
-
-```cpp
-MATCHER_P(name, param_name, description_string) { statements; }
-```
-
-where the description string can be either `""` or a `string` expression that
-references `negation` and `param_name`.
-
-For example:
-
-```cpp
-MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
-```
-
-will allow you to write:
-
-```cpp
-  EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
-```
-
-which may lead to this message (assuming `n` is 10):
-
-```shell
-  Value of: Blah("a")
-  Expected: has absolute value 10
-    Actual: -9
-```
-
-Note that both the matcher description and its parameter are printed, making the
-message human-friendly.
-
-In the matcher definition body, you can write `foo_type` to reference the type
-of a parameter named `foo`. For example, in the body of
-`MATCHER_P(HasAbsoluteValue, value)` above, you can write `value_type` to refer
-to the type of `value`.
-
-gMock also provides `MATCHER_P2`, `MATCHER_P3`, ..., up to `MATCHER_P10` to
-support multi-parameter matchers:
-
-```cpp
-MATCHER_Pk(name, param_1, ..., param_k, description_string) { statements; }
-```
-
-Please note that the custom description string is for a particular *instance* of
-the matcher, where the parameters have been bound to actual values. Therefore
-usually you'll want the parameter values to be part of the description. gMock
-lets you do that by referencing the matcher parameters in the description string
-expression.
-
-For example,
-
-```cpp
-using ::testing::PrintToString;
-MATCHER_P2(InClosedRange, low, hi,
-           absl::StrFormat("%s in range [%s, %s]", negation ? "isn't" : "is",
-                           PrintToString(low), PrintToString(hi))) {
-  return low <= arg && arg <= hi;
-}
-...
-EXPECT_THAT(3, InClosedRange(4, 6));
-```
-
-would generate a failure that contains the message:
-
-```shell
-  Expected: is in range [4, 6]
-```
-
-If you specify `""` as the description, the failure message will contain the
-sequence of words in the matcher name followed by the parameter values printed
-as a tuple. For example,
-
-```cpp
-  MATCHER_P2(InClosedRange, low, hi, "") { ... }
-  ...
-  EXPECT_THAT(3, InClosedRange(4, 6));
-```
-
-would generate a failure that contains the text:
-
-```shell
-  Expected: in closed range (4, 6)
-```
-
-For the purpose of typing, you can view
-
-```cpp
-MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
-```
-
-as shorthand for
-
-```cpp
-template <typename p1_type, ..., typename pk_type>
-FooMatcherPk<p1_type, ..., pk_type>
-Foo(p1_type p1, ..., pk_type pk) { ... }
-```
-
-When you write `Foo(v1, ..., vk)`, the compiler infers the types of the
-parameters `v1`, ..., and `vk` for you. If you are not happy with the result of
-the type inference, you can specify the types by explicitly instantiating the
-template, as in `Foo<long, bool>(5, false)`. As said earlier, you don't get to
-(or need to) specify `arg_type` as that's determined by the context in which the
-matcher is used.
-
-You can assign the result of expression `Foo(p1, ..., pk)` to a variable of type
-`FooMatcherPk<p1_type, ..., pk_type>`. This can be useful when composing
-matchers. Matchers that don't have a parameter or have only one parameter have
-special types: you can assign `Foo()` to a `FooMatcher`-typed variable, and
-assign `Foo(p)` to a `FooMatcherP<p_type>`-typed variable.
-
-While you can instantiate a matcher template with reference types, passing the
-parameters by pointer usually makes your code more readable. If, however, you
-still want to pass a parameter by reference, be aware that in the failure
-message generated by the matcher you will see the value of the referenced object
-but not its address.
-
-You can overload matchers with different numbers of parameters:
-
-```cpp
-MATCHER_P(Blah, a, description_string_1) { ... }
-MATCHER_P2(Blah, a, b, description_string_2) { ... }
-```
-
-While it's tempting to always use the `MATCHER*` macros when defining a new
-matcher, you should also consider implementing `MatcherInterface` or using
-`MakePolymorphicMatcher()` instead (see the recipes that follow), especially if
-you need to use the matcher a lot. While these approaches require more work,
-they give you more control on the types of the value being matched and the
-matcher parameters, which in general leads to better compiler error messages
-that pay off in the long run. They also allow overloading matchers based on
-parameter types (as opposed to just based on the number of parameters).
-
-### Writing New Monomorphic Matchers
-
-A matcher of argument type `T` implements `::testing::MatcherInterface<T>` and
-does two things: it tests whether a value of type `T` matches the matcher, and
-can describe what kind of values it matches. The latter ability is used for
-generating readable error messages when expectations are violated.
-
-The interface looks like this:
-
-```cpp
-class MatchResultListener {
- public:
-  ...
-  // Streams x to the underlying ostream; does nothing if the ostream
-  // is NULL.
-  template <typename T>
-  MatchResultListener& operator<<(const T& x);
-
-  // Returns the underlying ostream.
-  ::std::ostream* stream();
-};
-
-template <typename T>
-class MatcherInterface {
- public:
-  virtual ~MatcherInterface();
-
-  // Returns true if and only if the matcher matches x; also explains the match
-  // result to 'listener'.
-  virtual bool MatchAndExplain(T x, MatchResultListener* listener) const = 0;
-
-  // Describes this matcher to an ostream.
-  virtual void DescribeTo(::std::ostream* os) const = 0;
-
-  // Describes the negation of this matcher to an ostream.
-  virtual void DescribeNegationTo(::std::ostream* os) const;
-};
-```
-
-If you need a custom matcher but `Truly()` is not a good option (for example,
-you may not be happy with the way `Truly(predicate)` describes itself, or you
-may want your matcher to be polymorphic as `Eq(value)` is), you can define a
-matcher to do whatever you want in two steps: first implement the matcher
-interface, and then define a factory function to create a matcher instance. The
-second step is not strictly needed but it makes the syntax of using the matcher
-nicer.
-
-For example, you can define a matcher to test whether an `int` is divisible by 7
-and then use it like this:
-
-```cpp
-using ::testing::MakeMatcher;
-using ::testing::Matcher;
-using ::testing::MatcherInterface;
-using ::testing::MatchResultListener;
-
-class DivisibleBy7Matcher : public MatcherInterface<int> {
- public:
-  bool MatchAndExplain(int n,
-                       MatchResultListener* /* listener */) const override {
-    return (n % 7) == 0;
-  }
-
-  void DescribeTo(::std::ostream* os) const override {
-    *os << "is divisible by 7";
-  }
-
-  void DescribeNegationTo(::std::ostream* os) const override {
-    *os << "is not divisible by 7";
-  }
-};
-
-Matcher<int> DivisibleBy7() {
-  return MakeMatcher(new DivisibleBy7Matcher);
-}
-
-...
-  EXPECT_CALL(foo, Bar(DivisibleBy7()));
-```
-
-You may improve the matcher message by streaming additional information to the
-`listener` argument in `MatchAndExplain()`:
-
-```cpp
-class DivisibleBy7Matcher : public MatcherInterface<int> {
- public:
-  bool MatchAndExplain(int n,
-                       MatchResultListener* listener) const override {
-    const int remainder = n % 7;
-    if (remainder != 0) {
-      *listener << "the remainder is " << remainder;
-    }
-    return remainder == 0;
-  }
-  ...
-};
-```
-
-Then, `EXPECT_THAT(x, DivisibleBy7());` may generate a message like this:
-
-```shell
-Value of: x
-Expected: is divisible by 7
-  Actual: 23 (the remainder is 2)
-```
-
-### Writing New Polymorphic Matchers
-
-You've learned how to write your own matchers in the previous recipe. Just one
-problem: a matcher created using `MakeMatcher()` only works for one particular
-type of arguments. If you want a *polymorphic* matcher that works with arguments
-of several types (for instance, `Eq(x)` can be used to match a *`value`* as long
-as `value == x` compiles -- *`value`* and `x` don't have to share the same
-type), you can learn the trick from `testing/base/public/gmock-matchers.h` but
-it's a bit involved.
-
-Fortunately, most of the time you can define a polymorphic matcher easily with
-the help of `MakePolymorphicMatcher()`. Here's how you can define `NotNull()` as
-an example:
-
-```cpp
-using ::testing::MakePolymorphicMatcher;
-using ::testing::MatchResultListener;
-using ::testing::PolymorphicMatcher;
-
-class NotNullMatcher {
- public:
-  // To implement a polymorphic matcher, first define a COPYABLE class
-  // that has three members MatchAndExplain(), DescribeTo(), and
-  // DescribeNegationTo(), like the following.
-
-  // In this example, we want to use NotNull() with any pointer, so
-  // MatchAndExplain() accepts a pointer of any type as its first argument.
-  // In general, you can define MatchAndExplain() as an ordinary method or
-  // a method template, or even overload it.
-  template <typename T>
-  bool MatchAndExplain(T* p,
-                       MatchResultListener* /* listener */) const {
-    return p != NULL;
-  }
-
-  // Describes the property of a value matching this matcher.
-  void DescribeTo(std::ostream* os) const { *os << "is not NULL"; }
-
-  // Describes the property of a value NOT matching this matcher.
-  void DescribeNegationTo(std::ostream* os) const { *os << "is NULL"; }
-};
-
-// To construct a polymorphic matcher, pass an instance of the class
-// to MakePolymorphicMatcher().  Note the return type.
-PolymorphicMatcher<NotNullMatcher> NotNull() {
-  return MakePolymorphicMatcher(NotNullMatcher());
-}
-
-...
-
-  EXPECT_CALL(foo, Bar(NotNull()));  // The argument must be a non-NULL pointer.
-```
-
-**Note:** Your polymorphic matcher class does **not** need to inherit from
-`MatcherInterface` or any other class, and its methods do **not** need to be
-virtual.
-
-Like in a monomorphic matcher, you may explain the match result by streaming
-additional information to the `listener` argument in `MatchAndExplain()`.
-
-### Writing New Cardinalities
-
-A cardinality is used in `Times()` to tell gMock how many times you expect a
-call to occur. It doesn't have to be exact. For example, you can say
-`AtLeast(5)` or `Between(2, 4)`.
-
-If the [built-in set](cheat_sheet.md#CardinalityList) of cardinalities doesn't
-suit you, you are free to define your own by implementing the following
-interface (in namespace `testing`):
-
-```cpp
-class CardinalityInterface {
- public:
-  virtual ~CardinalityInterface();
-
-  // Returns true if and only if call_count calls will satisfy this cardinality.
-  virtual bool IsSatisfiedByCallCount(int call_count) const = 0;
-
-  // Returns true if and only if call_count calls will saturate this
-  // cardinality.
-  virtual bool IsSaturatedByCallCount(int call_count) const = 0;
-
-  // Describes self to an ostream.
-  virtual void DescribeTo(std::ostream* os) const = 0;
-};
-```
-
-For example, to specify that a call must occur even number of times, you can
-write
-
-```cpp
-using ::testing::Cardinality;
-using ::testing::CardinalityInterface;
-using ::testing::MakeCardinality;
-
-class EvenNumberCardinality : public CardinalityInterface {
- public:
-  bool IsSatisfiedByCallCount(int call_count) const override {
-    return (call_count % 2) == 0;
-  }
-
-  bool IsSaturatedByCallCount(int call_count) const override {
-    return false;
-  }
-
-  void DescribeTo(std::ostream* os) const {
-    *os << "called even number of times";
-  }
-};
-
-Cardinality EvenNumber() {
-  return MakeCardinality(new EvenNumberCardinality);
-}
-
-...
-  EXPECT_CALL(foo, Bar(3))
-      .Times(EvenNumber());
-```
-
-### Writing New Actions Quickly {#QuickNewActions}
-
-If the built-in actions don't work for you, you can easily define your own one.
-Just define a functor class with a (possibly templated) call operator, matching
-the signature of your action.
-
-```cpp
-struct Increment {
-  template <typename T>
-  T operator()(T* arg) {
-    return ++(*arg);
-  }
-}
-```
-
-The same approach works with stateful functors (or any callable, really):
-
-```
-struct MultiplyBy {
-  template <typename T>
-  T operator()(T arg) { return arg * multiplier; }
-
-  int multiplier;
-}
-
-// Then use:
-// EXPECT_CALL(...).WillOnce(MultiplyBy{7});
-```
-
-#### Legacy macro-based Actions
-
-Before C++11, the functor-based actions were not supported; the old way of
-writing actions was through a set of `ACTION*` macros. We suggest to avoid them
-in new code; they hide a lot of logic behind the macro, potentially leading to
-harder-to-understand compiler errors. Nevertheless, we cover them here for
-completeness.
-
-By writing
-
-```cpp
-ACTION(name) { statements; }
-```
-
-in a namespace scope (i.e. not inside a class or function), you will define an
-action with the given name that executes the statements. The value returned by
-`statements` will be used as the return value of the action. Inside the
-statements, you can refer to the K-th (0-based) argument of the mock function as
-`argK`. For example:
-
-```cpp
-ACTION(IncrementArg1) { return ++(*arg1); }
-```
-
-allows you to write
-
-```cpp
-... WillOnce(IncrementArg1());
-```
-
-Note that you don't need to specify the types of the mock function arguments.
-Rest assured that your code is type-safe though: you'll get a compiler error if
-`*arg1` doesn't support the `++` operator, or if the type of `++(*arg1)` isn't
-compatible with the mock function's return type.
-
-Another example:
-
-```cpp
-ACTION(Foo) {
-  (*arg2)(5);
-  Blah();
-  *arg1 = 0;
-  return arg0;
-}
-```
-
-defines an action `Foo()` that invokes argument #2 (a function pointer) with 5,
-calls function `Blah()`, sets the value pointed to by argument #1 to 0, and
-returns argument #0.
-
-For more convenience and flexibility, you can also use the following pre-defined
-symbols in the body of `ACTION`:
-
-`argK_type`     | The type of the K-th (0-based) argument of the mock function
-:-------------- | :-----------------------------------------------------------
-`args`          | All arguments of the mock function as a tuple
-`args_type`     | The type of all arguments of the mock function as a tuple
-`return_type`   | The return type of the mock function
-`function_type` | The type of the mock function
-
-For example, when using an `ACTION` as a stub action for mock function:
-
-```cpp
-int DoSomething(bool flag, int* ptr);
-```
-
-we have:
-
-Pre-defined Symbol | Is Bound To
------------------- | ---------------------------------
-`arg0`             | the value of `flag`
-`arg0_type`        | the type `bool`
-`arg1`             | the value of `ptr`
-`arg1_type`        | the type `int*`
-`args`             | the tuple `(flag, ptr)`
-`args_type`        | the type `std::tuple<bool, int*>`
-`return_type`      | the type `int`
-`function_type`    | the type `int(bool, int*)`
-
-#### Legacy macro-based parameterized Actions
-
-Sometimes you'll want to parameterize an action you define. For that we have
-another macro
-
-```cpp
-ACTION_P(name, param) { statements; }
-```
-
-For example,
-
-```cpp
-ACTION_P(Add, n) { return arg0 + n; }
-```
-
-will allow you to write
-
-```cpp
-// Returns argument #0 + 5.
-... WillOnce(Add(5));
-```
-
-For convenience, we use the term *arguments* for the values used to invoke the
-mock function, and the term *parameters* for the values used to instantiate an
-action.
-
-Note that you don't need to provide the type of the parameter either. Suppose
-the parameter is named `param`, you can also use the gMock-defined symbol
-`param_type` to refer to the type of the parameter as inferred by the compiler.
-For example, in the body of `ACTION_P(Add, n)` above, you can write `n_type` for
-the type of `n`.
-
-gMock also provides `ACTION_P2`, `ACTION_P3`, and etc to support multi-parameter
-actions. For example,
-
-```cpp
-ACTION_P2(ReturnDistanceTo, x, y) {
-  double dx = arg0 - x;
-  double dy = arg1 - y;
-  return sqrt(dx*dx + dy*dy);
-}
-```
-
-lets you write
-
-```cpp
-... WillOnce(ReturnDistanceTo(5.0, 26.5));
-```
-
-You can view `ACTION` as a degenerated parameterized action where the number of
-parameters is 0.
-
-You can also easily define actions overloaded on the number of parameters:
-
-```cpp
-ACTION_P(Plus, a) { ... }
-ACTION_P2(Plus, a, b) { ... }
-```
-
-### Restricting the Type of an Argument or Parameter in an ACTION
-
-For maximum brevity and reusability, the `ACTION*` macros don't ask you to
-provide the types of the mock function arguments and the action parameters.
-Instead, we let the compiler infer the types for us.
-
-Sometimes, however, we may want to be more explicit about the types. There are
-several tricks to do that. For example:
-
-```cpp
-ACTION(Foo) {
-  // Makes sure arg0 can be converted to int.
-  int n = arg0;
-  ... use n instead of arg0 here ...
-}
-
-ACTION_P(Bar, param) {
-  // Makes sure the type of arg1 is const char*.
-  ::testing::StaticAssertTypeEq<const char*, arg1_type>();
-
-  // Makes sure param can be converted to bool.
-  bool flag = param;
-}
-```
-
-where `StaticAssertTypeEq` is a compile-time assertion in googletest that
-verifies two types are the same.
-
-### Writing New Action Templates Quickly
-
-Sometimes you want to give an action explicit template parameters that cannot be
-inferred from its value parameters. `ACTION_TEMPLATE()` supports that and can be
-viewed as an extension to `ACTION()` and `ACTION_P*()`.
-
-The syntax:
-
-```cpp
-ACTION_TEMPLATE(ActionName,
-                HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
-                AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
-```
-
-defines an action template that takes *m* explicit template parameters and *n*
-value parameters, where *m* is in [1, 10] and *n* is in [0, 10]. `name_i` is the
-name of the *i*-th template parameter, and `kind_i` specifies whether it's a
-`typename`, an integral constant, or a template. `p_i` is the name of the *i*-th
-value parameter.
-
-Example:
-
-```cpp
-// DuplicateArg<k, T>(output) converts the k-th argument of the mock
-// function to type T and copies it to *output.
-ACTION_TEMPLATE(DuplicateArg,
-                // Note the comma between int and k:
-                HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
-                AND_1_VALUE_PARAMS(output)) {
-  *output = T(::std::get<k>(args));
-}
-```
-
-To create an instance of an action template, write:
-
-```cpp
-ActionName<t1, ..., t_m>(v1, ..., v_n)
-```
-
-where the `t`s are the template arguments and the `v`s are the value arguments.
-The value argument types are inferred by the compiler. For example:
-
-```cpp
-using ::testing::_;
-...
-  int n;
-  EXPECT_CALL(mock, Foo).WillOnce(DuplicateArg<1, unsigned char>(&n));
-```
-
-If you want to explicitly specify the value argument types, you can provide
-additional template arguments:
-
-```cpp
-ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
-```
-
-where `u_i` is the desired type of `v_i`.
-
-`ACTION_TEMPLATE` and `ACTION`/`ACTION_P*` can be overloaded on the number of
-value parameters, but not on the number of template parameters. Without the
-restriction, the meaning of the following is unclear:
-
-```cpp
-  OverloadedAction<int, bool>(x);
-```
-
-Are we using a single-template-parameter action where `bool` refers to the type
-of `x`, or a two-template-parameter action where the compiler is asked to infer
-the type of `x`?
-
-### Using the ACTION Object's Type
-
-If you are writing a function that returns an `ACTION` object, you'll need to
-know its type. The type depends on the macro used to define the action and the
-parameter types. The rule is relatively simple:
-
-| Given Definition              | Expression          | Has Type              |
-| ----------------------------- | ------------------- | --------------------- |
-| `ACTION(Foo)`                 | `Foo()`             | `FooAction`           |
-| `ACTION_TEMPLATE(Foo,`        | `Foo<t1, ...,       | `FooAction<t1, ...,   |

-: `AND_0_VALUE_PARAMS())`       :                     :                       :
-| `ACTION_P(Bar, param)`        | `Bar(int_value)`    | `BarActionP<int>`     |
-| `ACTION_TEMPLATE(Bar,`        | `Bar<t1, ..., t_m>` | `FooActionP<t1, ...,  |

-: `AND_1_VALUE_PARAMS(p1))`     :                     :                       :
-| `ACTION_P2(Baz, p1, p2)`      | `Baz(bool_value,`   | `BazActionP2<bool,    |
-:                               : `int_value)`        : int>`                 :
-| `ACTION_TEMPLATE(Baz,`        | `Baz<t1, ..., t_m>` | `FooActionP2<t1, ..., |
-: `HAS_m_TEMPLATE_PARAMS(...),` : `(bool_value,`      : t_m,` `bool, int>`    :
-: `AND_2_VALUE_PARAMS(p1, p2))` : `int_value)`        :                       :
-| ...                           | ...                 | ...                   |
-
-Note that we have to pick different suffixes (`Action`, `ActionP`, `ActionP2`,
-and etc) for actions with different numbers of value parameters, or the action
-definitions cannot be overloaded on the number of them.

-### Writing New Monomorphic Actions {#NewMonoActions}
-
-While the `ACTION*` macros are very convenient, sometimes they are
-inappropriate. For example, despite the tricks shown in the previous recipes,
-they don't let you directly specify the types of the mock function arguments and
-the action parameters, which in general leads to unoptimized compiler error
-messages that can baffle unfamiliar users. They also don't allow overloading
-actions based on parameter types without jumping through some hoops.
-
-An alternative to the `ACTION*` macros is to implement
-`::testing::ActionInterface<F>`, where `F` is the type of the mock function in
-which the action will be used. For example:
-
-```cpp
-template <typename F>
-class ActionInterface {
- public:
-  virtual ~ActionInterface();
-
-  // Performs the action.  Result is the return type of function type
-  // F, and ArgumentTuple is the tuple of arguments of F.
-  //
-
-  // For example, if F is int(bool, const string&), then Result would
-  // be int, and ArgumentTuple would be ::std::tuple<bool, const string&>.
-  virtual Result Perform(const ArgumentTuple& args) = 0;
-};
-```
-
-```cpp
-using ::testing::_;
-using ::testing::Action;
-using ::testing::ActionInterface;
-using ::testing::MakeAction;
-
-typedef int IncrementMethod(int*);
-
-class IncrementArgumentAction : public ActionInterface<IncrementMethod> {
- public:
-  int Perform(const ::std::tuple<int*>& args) override {
-    int* p = ::std::get<0>(args);  // Grabs the first argument.
-    return *p++;
-  }
-};
-
-Action<IncrementMethod> IncrementArgument() {
-  return MakeAction(new IncrementArgumentAction);
-}
-
-...
-  EXPECT_CALL(foo, Baz(_))
-      .WillOnce(IncrementArgument());
-
-  int n = 5;
-  foo.Baz(&n);  // Should return 5 and change n to 6.
-```
-
-### Writing New Polymorphic Actions {#NewPolyActions}
-
-The previous recipe showed you how to define your own action. This is all good,
-except that you need to know the type of the function in which the action will
-be used. Sometimes that can be a problem. For example, if you want to use the
-action in functions with *different* types (e.g. like `Return()` and
-`SetArgPointee()`).
-
-If an action can be used in several types of mock functions, we say it's
-*polymorphic*. The `MakePolymorphicAction()` function template makes it easy to
-define such an action:
-
-```cpp
-namespace testing {
-template <typename Impl>
-PolymorphicAction<Impl> MakePolymorphicAction(const Impl& impl);
-}  // namespace testing
-```
-
-As an example, let's define an action that returns the second argument in the
-mock function's argument list. The first step is to define an implementation
-class:
-
-```cpp
-class ReturnSecondArgumentAction {
- public:
-  template <typename Result, typename ArgumentTuple>
-  Result Perform(const ArgumentTuple& args) const {
-    // To get the i-th (0-based) argument, use ::std::get(args).
-    return ::std::get<1>(args);
-  }
-};
-```
-
-This implementation class does *not* need to inherit from any particular class.
-What matters is that it must have a `Perform()` method template. This method
-template takes the mock function's arguments as a tuple in a **single**
-argument, and returns the result of the action. It can be either `const` or not,
-but must be invokable with exactly one template argument, which is the result
-type. In other words, you must be able to call `Perform<R>(args)` where `R` is
-the mock function's return type and `args` is its arguments in a tuple.
-
-Next, we use `MakePolymorphicAction()` to turn an instance of the implementation
-class into the polymorphic action we need. It will be convenient to have a
-wrapper for this:
-
-```cpp
-using ::testing::MakePolymorphicAction;
-using ::testing::PolymorphicAction;
-
-PolymorphicAction<ReturnSecondArgumentAction> ReturnSecondArgument() {
-  return MakePolymorphicAction(ReturnSecondArgumentAction());
-}
-```
-
-Now, you can use this polymorphic action the same way you use the built-in ones:
-
-```cpp
-using ::testing::_;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD(int, DoThis, (bool flag, int n), (override));
-  MOCK_METHOD(string, DoThat, (int x, const char* str1, const char* str2),
-              (override));
-};
-
-  ...
-  MockFoo foo;
-  EXPECT_CALL(foo, DoThis).WillOnce(ReturnSecondArgument());
-  EXPECT_CALL(foo, DoThat).WillOnce(ReturnSecondArgument());
-  ...
-  foo.DoThis(true, 5);  // Will return 5.
-  foo.DoThat(1, "Hi", "Bye");  // Will return "Hi".
-```
-
-### Teaching gMock How to Print Your Values
-
-When an uninteresting or unexpected call occurs, gMock prints the argument
-values and the stack trace to help you debug. Assertion macros like
-`EXPECT_THAT` and `EXPECT_EQ` also print the values in question when the
-assertion fails. gMock and googletest do this using googletest's user-extensible
-value printer.
-
-This printer knows how to print built-in C++ types, native arrays, STL
-containers, and any type that supports the `<<` operator. For other types, it
-prints the raw bytes in the value and hopes that you the user can figure it out.
-[googletest's advanced guide](../../googletest/docs/advanced.md#teaching-googletest-how-to-print-your-values)
-explains how to extend the printer to do a better job at printing your
-particular type than to dump the bytes.

-
-### Mock std::function {#MockFunction}
-
-`std::function` is a general function type introduced in C++11. It is a
-preferred way of passing callbacks to new interfaces. Functions are copiable,
-and are not usually passed around by pointer, which makes them tricky to mock.
-But fear not - `MockFunction` can help you with that.
-
-`MockFunction<R(T1, ..., Tn)>` has a mock method `Call()` with the signature:
-
-```cpp
-  R Call(T1, ..., Tn);
-```
-
-It also has a `AsStdFunction()` method, which creates a `std::function` proxy
-forwarding to Call:
-
-```cpp
-  std::function<R(T1, ..., Tn)> AsStdFunction();
-```
-
-To use `MockFunction`, first create `MockFunction` object and set up
-expectations on its `Call` method. Then pass proxy obtained from
-`AsStdFunction()` to the code you are testing. For example:
-
-```cpp
-TEST(FooTest, RunsCallbackWithBarArgument) {
-  // 1. Create a mock object.
-  MockFunction<int(string)> mock_function;
-
-  // 2. Set expectations on Call() method.
-  EXPECT_CALL(mock_function, Call("bar")).WillOnce(Return(1));
-
-  // 3. Exercise code that uses std::function.
-  Foo(mock_function.AsStdFunction());
-  // Foo's signature can be either of:
-  // void Foo(const std::function<int(string)>& fun);
-  // void Foo(std::function<int(string)> fun);
-
-  // 4. All expectations will be verified when mock_function
-  //     goes out of scope and is destroyed.
-}
-```
-
-Remember that function objects created with `AsStdFunction()` are just
-forwarders. If you create multiple of them, they will share the same set of
-expectations.
-
-Although `std::function` supports unlimited number of arguments, `MockFunction`
-implementation is limited to ten. If you ever hit that limit... well, your
-callback has bigger problems than being mockable. :-)

-## gMock for Dummies {#GMockForDummies}
-
-<!-- GOOGLETEST_CM0013 DO NOT DELETE -->
-
-### What Is gMock?
-
-When you write a prototype or test, often it's not feasible or wise to rely on
-real objects entirely. A **mock object** implements the same interface as a real
-object (so it can be used as one), but lets you specify at run time how it will
-be used and what it should do (which methods will be called? in which order? how
-many times? with what arguments? what will they return? etc).
-
-**Note:** It is easy to confuse the term *fake objects* with mock objects. Fakes
-and mocks actually mean very different things in the Test-Driven Development
-(TDD) community:
-
-*   **Fake** objects have working implementations, but usually take some
-    shortcut (perhaps to make the operations less expensive), which makes them
-    not suitable for production. An in-memory file system would be an example of
-    a fake.
-*   **Mocks** are objects pre-programmed with *expectations*, which form a
-    specification of the calls they are expected to receive.
-
-If all this seems too abstract for you, don't worry - the most important thing
-to remember is that a mock allows you to check the *interaction* between itself
-and code that uses it. The difference between fakes and mocks shall become much
-clearer once you start to use mocks.
-
-**gMock** is a library (sometimes we also call it a "framework" to make it sound
-cool) for creating mock classes and using them. It does to C++ what
-jMock/EasyMock does to Java (well, more or less).
-
-When using gMock,
-
-1.  first, you use some simple macros to describe the interface you want to
-    mock, and they will expand to the implementation of your mock class;
-2.  next, you create some mock objects and specify its expectations and behavior
-    using an intuitive syntax;
-3.  then you exercise code that uses the mock objects. gMock will catch any
-    violation to the expectations as soon as it arises.
-
-### Why gMock?
-
-While mock objects help you remove unnecessary dependencies in tests and make
-them fast and reliable, using mocks manually in C++ is *hard*:
-
-*   Someone has to implement the mocks. The job is usually tedious and
-    error-prone. No wonder people go great distance to avoid it.
-*   The quality of those manually written mocks is a bit, uh, unpredictable. You
-    may see some really polished ones, but you may also see some that were
-    hacked up in a hurry and have all sorts of ad hoc restrictions.
-*   The knowledge you gained from using one mock doesn't transfer to the next
-    one.
-
-In contrast, Java and Python programmers have some fine mock frameworks (jMock,
-EasyMock, [Mox](http://wtf/mox), etc), which automate the creation of mocks. As
-a result, mocking is a proven effective technique and widely adopted practice in
-those communities. Having the right tool absolutely makes the difference.
-
-gMock was built to help C++ programmers. It was inspired by jMock and EasyMock,
-but designed with C++'s specifics in mind. It is your friend if any of the
-following problems is bothering you:
-
-*   You are stuck with a sub-optimal design and wish you had done more
-    prototyping before it was too late, but prototyping in C++ is by no means
-    "rapid".
-*   Your tests are slow as they depend on too many libraries or use expensive
-    resources (e.g. a database).
-*   Your tests are brittle as some resources they use are unreliable (e.g. the
-    network).
-*   You want to test how your code handles a failure (e.g. a file checksum
-    error), but it's not easy to cause one.
-*   You need to make sure that your module interacts with other modules in the
-    right way, but it's hard to observe the interaction; therefore you resort to
-    observing the side effects at the end of the action, but it's awkward at
-    best.
-*   You want to "mock out" your dependencies, except that they don't have mock
-    implementations yet; and, frankly, you aren't thrilled by some of those
-    hand-written mocks.
-
-We encourage you to use gMock as
-
-*   a *design* tool, for it lets you experiment with your interface design early
-    and often. More iterations lead to better designs!
-*   a *testing* tool to cut your tests' outbound dependencies and probe the
-    interaction between your module and its collaborators.
-
-### Getting Started
-
-gMock is bundled with googletest.
-
-### A Case for Mock Turtles
-
-Let's look at an example. Suppose you are developing a graphics program that
-relies on a [LOGO](http://en.wikipedia.org/wiki/Logo_programming_language)-like
-API for drawing. How would you test that it does the right thing? Well, you can
-run it and compare the screen with a golden screen snapshot, but let's admit it:
-tests like this are expensive to run and fragile (What if you just upgraded to a
-shiny new graphics card that has better anti-aliasing? Suddenly you have to
-update all your golden images.). It would be too painful if all your tests are
-like this. Fortunately, you learned about
-[Dependency Injection](http://en.wikipedia.org/wiki/Dependency_injection) and know the right thing
-to do: instead of having your application talk to the system API directly, wrap
-the API in an interface (say, `Turtle`) and code to that interface:
-
-```cpp
-class Turtle {
-  ...
-  virtual ~Turtle() {};
-  virtual void PenUp() = 0;
-  virtual void PenDown() = 0;
-  virtual void Forward(int distance) = 0;
-  virtual void Turn(int degrees) = 0;
-  virtual void GoTo(int x, int y) = 0;
-  virtual int GetX() const = 0;
-  virtual int GetY() const = 0;
-};
-```
-
-(Note that the destructor of `Turtle` **must** be virtual, as is the case for
-**all** classes you intend to inherit from - otherwise the destructor of the
-derived class will not be called when you delete an object through a base
-pointer, and you'll get corrupted program states like memory leaks.)
-
-You can control whether the turtle's movement will leave a trace using `PenUp()`
-and `PenDown()`, and control its movement using `Forward()`, `Turn()`, and
-`GoTo()`. Finally, `GetX()` and `GetY()` tell you the current position of the
-turtle.
-
-Your program will normally use a real implementation of this interface. In
-tests, you can use a mock implementation instead. This allows you to easily
-check what drawing primitives your program is calling, with what arguments, and
-in which order. Tests written this way are much more robust (they won't break
-because your new machine does anti-aliasing differently), easier to read and
-maintain (the intent of a test is expressed in the code, not in some binary
-images), and run *much, much faster*.
-
-### Writing the Mock Class
-
-If you are lucky, the mocks you need to use have already been implemented by
-some nice people. If, however, you find yourself in the position to write a mock
-class, relax - gMock turns this task into a fun game! (Well, almost.)
-
-#### How to Define It
-
-Using the `Turtle` interface as example, here are the simple steps you need to
-follow:
-
-*   Derive a class `MockTurtle` from `Turtle`.
-*   Take a *virtual* function of `Turtle` (while it's possible to
-    [mock non-virtual methods using templates](cook_book.md#MockingNonVirtualMethods),
-    it's much more involved).
-*   In the `public:` section of the child class, write `MOCK_METHOD();`
-*   Now comes the fun part: you take the function signature, cut-and-paste it
-    into the macro, and add two commas - one between the return type and the
-    name, another between the name and the argument list.
-*   If you're mocking a const method, add a 4th parameter containing `(const)`
-    (the parentheses are required).
-*   Since you're overriding a virtual method, we suggest adding the `override`
-    keyword. For const methods the 4th parameter becomes `(const, override)`,
-    for non-const methods just `(override)`. This isn't mandatory.
-*   Repeat until all virtual functions you want to mock are done. (It goes
-    without saying that *all* pure virtual methods in your abstract class must
-    be either mocked or overridden.)
-
-After the process, you should have something like:
-
-```cpp
-#include "gmock/gmock.h"  // Brings in gMock.
-
-class MockTurtle : public Turtle {
- public:
-  ...
-  MOCK_METHOD(void, PenUp, (), (override));
-  MOCK_METHOD(void, PenDown, (), (override));
-  MOCK_METHOD(void, Forward, (int distance), (override));
-  MOCK_METHOD(void, Turn, (int degrees), (override));
-  MOCK_METHOD(void, GoTo, (int x, int y), (override));
-  MOCK_METHOD(int, GetX, (), (const, override));
-  MOCK_METHOD(int, GetY, (), (const, override));
-};
-```
-
-You don't need to define these mock methods somewhere else - the `MOCK_METHOD`
-macro will generate the definitions for you. It's that simple!
-
-#### Where to Put It
-
-When you define a mock class, you need to decide where to put its definition.
-Some people put it in a `_test.cc`. This is fine when the interface being mocked
-(say, `Foo`) is owned by the same person or team. Otherwise, when the owner of
-`Foo` changes it, your test could break. (You can't really expect `Foo`'s
-maintainer to fix every test that uses `Foo`, can you?)
-
-So, the rule of thumb is: if you need to mock `Foo` and it's owned by others,
-define the mock class in `Foo`'s package (better, in a `testing` sub-package
-such that you can clearly separate production code and testing utilities), put
-it in a `.h` and a `cc_library`. Then everyone can reference them from their
-tests. If `Foo` ever changes, there is only one copy of `MockFoo` to change, and
-only tests that depend on the changed methods need to be fixed.
-
-Another way to do it: you can introduce a thin layer `FooAdaptor` on top of
-`Foo` and code to this new interface. Since you own `FooAdaptor`, you can absorb
-changes in `Foo` much more easily. While this is more work initially, carefully
-choosing the adaptor interface can make your code easier to write and more
-readable (a net win in the long run), as you can choose `FooAdaptor` to fit your
-specific domain much better than `Foo` does.
-

-
-### Using Mocks in Tests
-
-Once you have a mock class, using it is easy. The typical work flow is:
-
-1.  Import the gMock names from the `testing` namespace such that you can use
-    them unqualified (You only have to do it once per file. Remember that
-    namespaces are a good idea.
-2.  Create some mock objects.
-3.  Specify your expectations on them (How many times will a method be called?
-    With what arguments? What should it do? etc.).
-4.  Exercise some code that uses the mocks; optionally, check the result using
-    googletest assertions. If a mock method is called more than expected or with
-    wrong arguments, you'll get an error immediately.
-5.  When a mock is destructed, gMock will automatically check whether all
-    expectations on it have been satisfied.
-
-Here's an example:
-
-```cpp
-#include "path/to/mock-turtle.h"
-#include "gmock/gmock.h"
-#include "gtest/gtest.h"
-
-using ::testing::AtLeast;                         // #1
-
-TEST(PainterTest, CanDrawSomething) {
-  MockTurtle turtle;                              // #2
-  EXPECT_CALL(turtle, PenDown())                  // #3
-      .Times(AtLeast(1));
-
-  Painter painter(&turtle);                       // #4
-
-  EXPECT_TRUE(painter.DrawCircle(0, 0, 10));      // #5
-}
-```
-
-As you might have guessed, this test checks that `PenDown()` is called at least
-once. If the `painter` object didn't call this method, your test will fail with
-a message like this:
-
-```text
-path/to/my_test.cc:119: Failure
-Actual function call count doesn't match this expectation:
-Actually: never called;
-Expected: called at least once.
-Stack trace:
-...
-```
-
-**Tip 1:** If you run the test from an Emacs buffer, you can hit <Enter> on the
-line number to jump right to the failed expectation.
-
-**Tip 2:** If your mock objects are never deleted, the final verification won't
-happen. Therefore it's a good idea to turn on the heap checker in your tests
-when you allocate mocks on the heap. You get that automatically if you use the
-`gtest_main` library already.
-
-**Important note:** gMock requires expectations to be set **before** the mock
-functions are called, otherwise the behavior is **undefined**. In particular,
-you mustn't interleave `EXPECT_CALL()s` and calls to the mock functions.
-
-This means `EXPECT_CALL()` should be read as expecting that a call will occur
-*in the future*, not that a call has occurred. Why does gMock work like that?
-Well, specifying the expectation beforehand allows gMock to report a violation
-as soon as it rises, when the context (stack trace, etc) is still available.
-This makes debugging much easier.
-
-Admittedly, this test is contrived and doesn't do much. You can easily achieve
-the same effect without using gMock. However, as we shall reveal soon, gMock
-allows you to do *so much more* with the mocks.
-
-### Setting Expectations
-
-The key to using a mock object successfully is to set the *right expectations*
-on it. If you set the expectations too strict, your test will fail as the result
-of unrelated changes. If you set them too loose, bugs can slip through. You want
-to do it just right such that your test can catch exactly the kind of bugs you
-intend it to catch. gMock provides the necessary means for you to do it "just
-right."
-
-#### General Syntax
-
-In gMock we use the `EXPECT_CALL()` macro to set an expectation on a mock
-method. The general syntax is:
-
-```cpp
-EXPECT_CALL(mock_object, method(matchers))
-    .Times(cardinality)
-    .WillOnce(action)
-    .WillRepeatedly(action);
-```
-
-The macro has two arguments: first the mock object, and then the method and its
-arguments. Note that the two are separated by a comma (`,`), not a period (`.`).
-(Why using a comma? The answer is that it was necessary for technical reasons.)
-If the method is not overloaded, the macro can also be called without matchers:
-
-```cpp
-EXPECT_CALL(mock_object, non-overloaded-method)
-    .Times(cardinality)
-    .WillOnce(action)
-    .WillRepeatedly(action);
-```
-
-This syntax allows the test writer to specify "called with any arguments"
-without explicitly specifying the number or types of arguments. To avoid
-unintended ambiguity, this syntax may only be used for methods which are not
-overloaded
-
-Either form of the macro can be followed by some optional *clauses* that provide
-more information about the expectation. We'll discuss how each clause works in
-the coming sections.
-
-This syntax is designed to make an expectation read like English. For example,
-you can probably guess that
-
-```cpp
-using ::testing::Return;
-...
-EXPECT_CALL(turtle, GetX())
-    .Times(5)
-    .WillOnce(Return(100))
-    .WillOnce(Return(150))
-    .WillRepeatedly(Return(200));
-```
-
-says that the `turtle` object's `GetX()` method will be called five times, it
-will return 100 the first time, 150 the second time, and then 200 every time.
-Some people like to call this style of syntax a Domain-Specific Language (DSL).
-
-**Note:** Why do we use a macro to do this? Well it serves two purposes: first
-it makes expectations easily identifiable (either by `gsearch` or by a human
-reader), and second it allows gMock to include the source file location of a
-failed expectation in messages, making debugging easier.
-
-#### Matchers: What Arguments Do We Expect?
-
-When a mock function takes arguments, we may specify what arguments we are
-expecting, for example:
-
-```cpp
-// Expects the turtle to move forward by 100 units.
-EXPECT_CALL(turtle, Forward(100));
-```
-
-Oftentimes you do not want to be too specific. Remember that talk about tests
-being too rigid? Over specification leads to brittle tests and obscures the
-intent of tests. Therefore we encourage you to specify only what's necessary—no
-more, no less. If you aren't interested in the value of an argument, write `_`
-as the argument, which means "anything goes":
-
-```cpp
-using ::testing::_;
-...
-// Expects that the turtle jumps to somewhere on the x=50 line.
-EXPECT_CALL(turtle, GoTo(50, _));
-```
-
-`_` is an instance of what we call **matchers**. A matcher is like a predicate
-and can test whether an argument is what we'd expect. You can use a matcher
-inside `EXPECT_CALL()` wherever a function argument is expected. `_` is a
-convenient way of saying "any value".
-
-In the above examples, `100` and `50` are also matchers; implicitly, they are
-the same as `Eq(100)` and `Eq(50)`, which specify that the argument must be
-equal (using `operator==`) to the matcher argument. There are many
-[built-in matchers](#MatcherList) for common types (as well as
-[custom matchers](cook_book.md#NewMatchers)); for example:
-
-```cpp
-using ::testing::Ge;
-...
-// Expects the turtle moves forward by at least 100.
-EXPECT_CALL(turtle, Forward(Ge(100)));
-```
-
-If you don't care about *any* arguments, rather than specify `_` for each of
-them you may instead omit the parameter list:
-
-```cpp
-// Expects the turtle to move forward.
-EXPECT_CALL(turtle, Forward);
-// Expects the turtle to jump somewhere.
-EXPECT_CALL(turtle, GoTo);
-```
-
-This works for all non-overloaded methods; if a method is overloaded, you need
-to help gMock resolve which overload is expected by specifying the number of
-arguments and possibly also the
-[types of the arguments](cook_book.md#SelectOverload).
-
-#### Cardinalities: How Many Times Will It Be Called?
-
-The first clause we can specify following an `EXPECT_CALL()` is `Times()`. We
-call its argument a **cardinality** as it tells *how many times* the call should
-occur. It allows us to repeat an expectation many times without actually writing
-it as many times. More importantly, a cardinality can be "fuzzy", just like a
-matcher can be. This allows a user to express the intent of a test exactly.
-
-An interesting special case is when we say `Times(0)`. You may have guessed - it
-means that the function shouldn't be called with the given arguments at all, and
-gMock will report a googletest failure whenever the function is (wrongfully)
-called.
-
-We've seen `AtLeast(n)` as an example of fuzzy cardinalities earlier. For the
-list of built-in cardinalities you can use, see
-[here](cheat_sheet.md#CardinalityList).
-
-The `Times()` clause can be omitted. **If you omit `Times()`, gMock will infer
-the cardinality for you.** The rules are easy to remember:
-
-*   If **neither** `WillOnce()` **nor** `WillRepeatedly()` is in the
-    `EXPECT_CALL()`, the inferred cardinality is `Times(1)`.
-*   If there are *n* `WillOnce()`'s but **no** `WillRepeatedly()`, where *n* >=
-    1, the cardinality is `Times(n)`.
-*   If there are *n* `WillOnce()`'s and **one** `WillRepeatedly()`, where *n* >=
-    0, the cardinality is `Times(AtLeast(n))`.
-
-**Quick quiz:** what do you think will happen if a function is expected to be
-called twice but actually called four times?
-
-#### Actions: What Should It Do?
-
-Remember that a mock object doesn't really have a working implementation? We as
-users have to tell it what to do when a method is invoked. This is easy in
-gMock.
-
-First, if the return type of a mock function is a built-in type or a pointer,
-the function has a **default action** (a `void` function will just return, a
-`bool` function will return `false`, and other functions will return 0). In
-addition, in C++ 11 and above, a mock function whose return type is
-default-constructible (i.e. has a default constructor) has a default action of
-returning a default-constructed value. If you don't say anything, this behavior
-will be used.
-
-Second, if a mock function doesn't have a default action, or the default action
-doesn't suit you, you can specify the action to be taken each time the
-expectation matches using a series of `WillOnce()` clauses followed by an
-optional `WillRepeatedly()`. For example,
-
-```cpp
-using ::testing::Return;
-...
-EXPECT_CALL(turtle, GetX())
-     .WillOnce(Return(100))
-     .WillOnce(Return(200))
-     .WillOnce(Return(300));
-```
-
-says that `turtle.GetX()` will be called *exactly three times* (gMock inferred
-this from how many `WillOnce()` clauses we've written, since we didn't
-explicitly write `Times()`), and will return 100, 200, and 300 respectively.
-
-```cpp
-using ::testing::Return;
-...
-EXPECT_CALL(turtle, GetY())
-     .WillOnce(Return(100))
-     .WillOnce(Return(200))
-     .WillRepeatedly(Return(300));
-```
-
-says that `turtle.GetY()` will be called *at least twice* (gMock knows this as
-we've written two `WillOnce()` clauses and a `WillRepeatedly()` while having no
-explicit `Times()`), will return 100 and 200 respectively the first two times,
-and 300 from the third time on.
-
-Of course, if you explicitly write a `Times()`, gMock will not try to infer the
-cardinality itself. What if the number you specified is larger than there are
-`WillOnce()` clauses? Well, after all `WillOnce()`s are used up, gMock will do
-the *default* action for the function every time (unless, of course, you have a
-`WillRepeatedly()`.).
-
-What can we do inside `WillOnce()` besides `Return()`? You can return a
-reference using `ReturnRef(*variable*)`, or invoke a pre-defined function, among
-[others](cook_book.md#using-actions).
-
-**Important note:** The `EXPECT_CALL()` statement evaluates the action clause
-only once, even though the action may be performed many times. Therefore you
-must be careful about side effects. The following may not do what you want:
-
-```cpp
-using ::testing::Return;
-...
-int n = 100;
-EXPECT_CALL(turtle, GetX())
-    .Times(4)
-    .WillRepeatedly(Return(n++));
-```
-
-Instead of returning 100, 101, 102, ..., consecutively, this mock function will
-always return 100 as `n++` is only evaluated once. Similarly, `Return(new Foo)`
-will create a new `Foo` object when the `EXPECT_CALL()` is executed, and will
-return the same pointer every time. If you want the side effect to happen every
-time, you need to define a custom action, which we'll teach in the
-[cook book](http://<!-- GOOGLETEST_CM0012 DO NOT DELETE -->).
-
-Time for another quiz! What do you think the following means?
-
-```cpp
-using ::testing::Return;
-...
-EXPECT_CALL(turtle, GetY())
-    .Times(4)
-    .WillOnce(Return(100));
-```
-
-Obviously `turtle.GetY()` is expected to be called four times. But if you think
-it will return 100 every time, think twice! Remember that one `WillOnce()`
-clause will be consumed each time the function is invoked and the default action
-will be taken afterwards. So the right answer is that `turtle.GetY()` will
-return 100 the first time, but **return 0 from the second time on**, as
-returning 0 is the default action for `int` functions.
-
-#### Using Multiple Expectations {#MultiExpectations}
-
-So far we've only shown examples where you have a single expectation. More
-realistically, you'll specify expectations on multiple mock methods which may be
-from multiple mock objects.
-
-By default, when a mock method is invoked, gMock will search the expectations in
-the **reverse order** they are defined, and stop when an active expectation that
-matches the arguments is found (you can think of it as "newer rules override
-older ones."). If the matching expectation cannot take any more calls, you will
-get an upper-bound-violated failure. Here's an example:
-
-```cpp
-using ::testing::_;
-...
-EXPECT_CALL(turtle, Forward(_));  // #1
-EXPECT_CALL(turtle, Forward(10))  // #2
-    .Times(2);
-```
-
-If `Forward(10)` is called three times in a row, the third time it will be an
-error, as the last matching expectation (#2) has been saturated. If, however,
-the third `Forward(10)` call is replaced by `Forward(20)`, then it would be OK,
-as now #1 will be the matching expectation.
-
-**Note:** Why does gMock search for a match in the *reverse* order of the
-expectations? The reason is that this allows a user to set up the default
-expectations in a mock object's constructor or the test fixture's set-up phase
-and then customize the mock by writing more specific expectations in the test
-body. So, if you have two expectations on the same method, you want to put the
-one with more specific matchers **after** the other, or the more specific rule
-would be shadowed by the more general one that comes after it.
-
-**Tip:** It is very common to start with a catch-all expectation for a method
-and `Times(AnyNumber())` (omitting arguments, or with `_` for all arguments, if
-overloaded). This makes any calls to the method expected. This is not necessary
-for methods that are not mentioned at all (these are "uninteresting"), but is
-useful for methods that have some expectations, but for which other calls are
-ok. See
-[Understanding Uninteresting vs Unexpected Calls](cook_book.md#uninteresting-vs-unexpected).
-
-#### Ordered vs Unordered Calls {#OrderedCalls}
-
-By default, an expectation can match a call even though an earlier expectation
-hasn't been satisfied. In other words, the calls don't have to occur in the
-order the expectations are specified.
-
-Sometimes, you may want all the expected calls to occur in a strict order. To
-say this in gMock is easy:
-
-```cpp
-using ::testing::InSequence;
-...
-TEST(FooTest, DrawsLineSegment) {
-  ...
-  {
-    InSequence seq;
-
-    EXPECT_CALL(turtle, PenDown());
-    EXPECT_CALL(turtle, Forward(100));
-    EXPECT_CALL(turtle, PenUp());
-  }
-  Foo();
-}
-```
-
-By creating an object of type `InSequence`, all expectations in its scope are
-put into a *sequence* and have to occur *sequentially*. Since we are just
-relying on the constructor and destructor of this object to do the actual work,
-its name is really irrelevant.
-
-In this example, we test that `Foo()` calls the three expected functions in the
-order as written. If a call is made out-of-order, it will be an error.
-
-(What if you care about the relative order of some of the calls, but not all of
-them? Can you specify an arbitrary partial order? The answer is ... yes! The
-details can be found [here](cook_book.md#OrderedCalls).)
-
-#### All Expectations Are Sticky (Unless Said Otherwise) {#StickyExpectations}
-
-Now let's do a quick quiz to see how well you can use this mock stuff already.
-How would you test that the turtle is asked to go to the origin *exactly twice*
-(you want to ignore any other instructions it receives)?
-
-After you've come up with your answer, take a look at ours and compare notes
-(solve it yourself first - don't cheat!):
-
-```cpp
-using ::testing::_;
-using ::testing::AnyNumber;
-...
-EXPECT_CALL(turtle, GoTo(_, _))  // #1
-     .Times(AnyNumber());
-EXPECT_CALL(turtle, GoTo(0, 0))  // #2
-     .Times(2);
-```
-
-Suppose `turtle.GoTo(0, 0)` is called three times. In the third time, gMock will
-see that the arguments match expectation #2 (remember that we always pick the
-last matching expectation). Now, since we said that there should be only two
-such calls, gMock will report an error immediately. This is basically what we've
-told you in the [Using Multiple Expectations](#MultiExpectations) section above.
-
-This example shows that **expectations in gMock are "sticky" by default**, in
-the sense that they remain active even after we have reached their invocation
-upper bounds. This is an important rule to remember, as it affects the meaning
-of the spec, and is **different** to how it's done in many other mocking
-frameworks (Why'd we do that? Because we think our rule makes the common cases
-easier to express and understand.).
-
-Simple? Let's see if you've really understood it: what does the following code
-say?
-
-```cpp
-using ::testing::Return;
-...
-for (int i = n; i > 0; i--) {
-  EXPECT_CALL(turtle, GetX())
-      .WillOnce(Return(10*i));
-}
-```
-
-If you think it says that `turtle.GetX()` will be called `n` times and will
-return 10, 20, 30, ..., consecutively, think twice! The problem is that, as we
-said, expectations are sticky. So, the second time `turtle.GetX()` is called,
-the last (latest) `EXPECT_CALL()` statement will match, and will immediately
-lead to an "upper bound violated" error - this piece of code is not very useful!
-
-One correct way of saying that `turtle.GetX()` will return 10, 20, 30, ..., is
-to explicitly say that the expectations are *not* sticky. In other words, they
-should *retire* as soon as they are saturated:
-
-```cpp
-using ::testing::Return;
-...
-for (int i = n; i > 0; i--) {
-  EXPECT_CALL(turtle, GetX())
-      .WillOnce(Return(10*i))
-      .RetiresOnSaturation();
-}
-```
-
-And, there's a better way to do it: in this case, we expect the calls to occur
-in a specific order, and we line up the actions to match the order. Since the
-order is important here, we should make it explicit using a sequence:
-
-```cpp
-using ::testing::InSequence;
-using ::testing::Return;
-...
-{
-  InSequence s;
-
-  for (int i = 1; i <= n; i++) {
-    EXPECT_CALL(turtle, GetX())
-        .WillOnce(Return(10*i))
-        .RetiresOnSaturation();
-  }
-}
-```
-
-By the way, the other situation where an expectation may *not* be sticky is when
-it's in a sequence - as soon as another expectation that comes after it in the
-sequence has been used, it automatically retires (and will never be used to
-match any call).
-
-#### Uninteresting Calls
-
-A mock object may have many methods, and not all of them are that interesting.
-For example, in some tests we may not care about how many times `GetX()` and
-`GetY()` get called.
-
-In gMock, if you are not interested in a method, just don't say anything about
-it. If a call to this method occurs, you'll see a warning in the test output,
-but it won't be a failure. This is called "naggy" behavior; to change, see
-[The Nice, the Strict, and the Naggy](cook_book.md#NiceStrictNaggy).

-## Legacy gMock FAQ {#GMockFaq}
-
-<!-- GOOGLETEST_CM0021 DO NOT DELETE -->
-
-### When I call a method on my mock object, the method for the real object is invoked instead. What's the problem?
-
-In order for a method to be mocked, it must be *virtual*, unless you use the
-[high-perf dependency injection technique](#MockingNonVirtualMethods).
-
-### Can I mock a variadic function?
-
-You cannot mock a variadic function (i.e. a function taking ellipsis (`...`)
-arguments) directly in gMock.
-
-The problem is that in general, there is *no way* for a mock object to know how
-many arguments are passed to the variadic method, and what the arguments' types
-are. Only the *author of the base class* knows the protocol, and we cannot look
-into his or her head.
-
-Therefore, to mock such a function, the *user* must teach the mock object how to
-figure out the number of arguments and their types. One way to do it is to
-provide overloaded versions of the function.
-
-Ellipsis arguments are inherited from C and not really a C++ feature. They are
-unsafe to use and don't work with arguments that have constructors or
-destructors. Therefore we recommend to avoid them in C++ as much as possible.
-
-### MSVC gives me warning C4301 or C4373 when I define a mock method with a const parameter. Why?
-
-If you compile this using Microsoft Visual C++ 2005 SP1:
-
-```cpp
-class Foo {
-  ...
-  virtual void Bar(const int i) = 0;
-};
-
-class MockFoo : public Foo {
-  ...
-  MOCK_METHOD(void, Bar, (const int i), (override));
-};
-```
-
-You may get the following warning:
-
-```shell
-warning C4301: 'MockFoo::Bar': overriding virtual function only differs from 'Foo::Bar' by const/volatile qualifier
-```
-
-This is a MSVC bug. The same code compiles fine with gcc, for example. If you
-use Visual C++ 2008 SP1, you would get the warning:
-
-```shell
-warning C4373: 'MockFoo::Bar': virtual function overrides 'Foo::Bar', previous versions of the compiler did not override when parameters only differed by const/volatile qualifiers
-```
-
-In C++, if you *declare* a function with a `const` parameter, the `const`
-modifier is ignored. Therefore, the `Foo` base class above is equivalent to:
-
-```cpp
-class Foo {
-  ...
-  virtual void Bar(int i) = 0;  // int or const int?  Makes no difference.
-};
-```
-
-In fact, you can *declare* `Bar()` with an `int` parameter, and define it with a
-`const int` parameter. The compiler will still match them up.
-
-Since making a parameter `const` is meaningless in the method declaration, we
-recommend to remove it in both `Foo` and `MockFoo`. That should workaround the
-VC bug.
-
-Note that we are talking about the *top-level* `const` modifier here. If the
-function parameter is passed by pointer or reference, declaring the pointee or
-referee as `const` is still meaningful. For example, the following two
-declarations are *not* equivalent:
-
-```cpp
-void Bar(int* p);         // Neither p nor *p is const.
-void Bar(const int* p);  // p is not const, but *p is.
-```
-

-
-### I can't figure out why gMock thinks my expectations are not satisfied. What should I do?
-
-You might want to run your test with `--gmock_verbose=info`. This flag lets
-gMock print a trace of every mock function call it receives. By studying the
-trace, you'll gain insights on why the expectations you set are not met.
-
-If you see the message "The mock function has no default action set, and its
-return type has no default value set.", then try
-[adding a default action](for_dummies.md#DefaultValue). Due to a known issue,
-unexpected calls on mocks without default actions don't print out a detailed
-comparison between the actual arguments and the expected arguments.
-
-### My program crashed and `ScopedMockLog` spit out tons of messages. Is it a gMock bug?
-
-gMock and `ScopedMockLog` are likely doing the right thing here.
-
-When a test crashes, the failure signal handler will try to log a lot of
-information (the stack trace, and the address map, for example). The messages
-are compounded if you have many threads with depth stacks. When `ScopedMockLog`
-intercepts these messages and finds that they don't match any expectations, it
-prints an error for each of them.
-
-You can learn to ignore the errors, or you can rewrite your expectations to make
-your test more robust, for example, by adding something like:
-
-```cpp
-using ::testing::AnyNumber;
-using ::testing::Not;
-...
-  // Ignores any log not done by us.
-  EXPECT_CALL(log, Log(_, Not(EndsWith("/my_file.cc")), _))
-      .Times(AnyNumber());
-```
-
-### How can I assert that a function is NEVER called?
-
-```cpp
-using ::testing::_;
-...
-  EXPECT_CALL(foo, Bar(_))
-      .Times(0);
-```
-
-<!-- GOOGLETEST_CM0031 DO NOT DELETE -->
-
-### I have a failed test where gMock tells me TWICE that a particular expectation is not satisfied. Isn't this redundant?
-
-When gMock detects a failure, it prints relevant information (the mock function
-arguments, the state of relevant expectations, and etc) to help the user debug.
-If another failure is detected, gMock will do the same, including printing the
-state of relevant expectations.
-
-Sometimes an expectation's state didn't change between two failures, and you'll
-see the same description of the state twice. They are however *not* redundant,
-as they refer to *different points in time*. The fact they are the same *is*
-interesting information.
-
-### I get a heapcheck failure when using a mock object, but using a real object is fine. What can be wrong?
-
-Does the class (hopefully a pure interface) you are mocking have a virtual
-destructor?
-
-Whenever you derive from a base class, make sure its destructor is virtual.
-Otherwise Bad Things will happen. Consider the following code:
-
-```cpp
-class Base {
- public:
-  // Not virtual, but should be.
-  ~Base() { ... }
-  ...
-};
-
-class Derived : public Base {
- public:
-  ...
- private:
-  std::string value_;
-};
-
-...
-  Base* p = new Derived;
-  ...
-  delete p;  // Surprise! ~Base() will be called, but ~Derived() will not
-                 // - value_ is leaked.
-```
-
-By changing `~Base()` to virtual, `~Derived()` will be correctly called when
-`delete p` is executed, and the heap checker will be happy.
-
-### The "newer expectations override older ones" rule makes writing expectations awkward. Why does gMock do that?
-
-When people complain about this, often they are referring to code like:
-
-```cpp
-using ::testing::Return;
-...
-  // foo.Bar() should be called twice, return 1 the first time, and return
-  // 2 the second time.  However, I have to write the expectations in the
-  // reverse order.  This sucks big time!!!
-  EXPECT_CALL(foo, Bar())
-      .WillOnce(Return(2))
-      .RetiresOnSaturation();
-  EXPECT_CALL(foo, Bar())
-      .WillOnce(Return(1))
-      .RetiresOnSaturation();
-```
-
-The problem, is that they didn't pick the **best** way to express the test's
-intent.
-
-By default, expectations don't have to be matched in *any* particular order. If
-you want them to match in a certain order, you need to be explicit. This is
-gMock's (and jMock's) fundamental philosophy: it's easy to accidentally
-over-specify your tests, and we want to make it harder to do so.
-
-There are two better ways to write the test spec. You could either put the
-expectations in sequence:
-
-```cpp
-using ::testing::Return;
-...
-  // foo.Bar() should be called twice, return 1 the first time, and return
-  // 2 the second time.  Using a sequence, we can write the expectations
-  // in their natural order.
-  {
-    InSequence s;
-    EXPECT_CALL(foo, Bar())
-        .WillOnce(Return(1))
-        .RetiresOnSaturation();
-    EXPECT_CALL(foo, Bar())
-        .WillOnce(Return(2))
-        .RetiresOnSaturation();
-  }
-```
-
-or you can put the sequence of actions in the same expectation:
-
-```cpp
-using ::testing::Return;
-...
-  // foo.Bar() should be called twice, return 1 the first time, and return
-  // 2 the second time.
-  EXPECT_CALL(foo, Bar())
-      .WillOnce(Return(1))
-      .WillOnce(Return(2))
-      .RetiresOnSaturation();
-```
-
-Back to the original questions: why does gMock search the expectations (and
-`ON_CALL`s) from back to front? Because this allows a user to set up a mock's
-behavior for the common case early (e.g. in the mock's constructor or the test
-fixture's set-up phase) and customize it with more specific rules later. If
-gMock searches from front to back, this very useful pattern won't be possible.
-
-### gMock prints a warning when a function without EXPECT_CALL is called, even if I have set its behavior using ON_CALL. Would it be reasonable not to show the warning in this case?
-
-When choosing between being neat and being safe, we lean toward the latter. So
-the answer is that we think it's better to show the warning.
-
-Often people write `ON_CALL`s in the mock object's constructor or `SetUp()`, as
-the default behavior rarely changes from test to test. Then in the test body
-they set the expectations, which are often different for each test. Having an
-`ON_CALL` in the set-up part of a test doesn't mean that the calls are expected.
-If there's no `EXPECT_CALL` and the method is called, it's possibly an error. If
-we quietly let the call go through without notifying the user, bugs may creep in
-unnoticed.
-
-If, however, you are sure that the calls are OK, you can write
-
-```cpp
-using ::testing::_;
-...
-  EXPECT_CALL(foo, Bar(_))
-      .WillRepeatedly(...);
-```
-
-instead of
-
-```cpp
-using ::testing::_;
-...
-  ON_CALL(foo, Bar(_))
-      .WillByDefault(...);
-```
-
-This tells gMock that you do expect the calls and no warning should be printed.
-
-Also, you can control the verbosity by specifying `--gmock_verbose=error`. Other
-values are `info` and `warning`. If you find the output too noisy when
-debugging, just choose a less verbose level.
-
-### How can I delete the mock function's argument in an action?
-
-If your mock function takes a pointer argument and you want to delete that
-argument, you can use testing::DeleteArg<N>() to delete the N'th (zero-indexed)
-argument:
-
-```cpp
-using ::testing::_;
-  ...
-  MOCK_METHOD(void, Bar, (X* x, const Y& y));
-  ...

-
-### How can I perform an arbitrary action on a mock function's argument?
-
-If you find yourself needing to perform some action that's not supported by
-gMock directly, remember that you can define your own actions using
-[`MakeAction()`](#NewMonoActions) or
-[`MakePolymorphicAction()`](#NewPolyActions), or you can write a stub function
-and invoke it using [`Invoke()`](#FunctionsAsActions).
-
-```cpp
-using ::testing::_;
-using ::testing::Invoke;
-  ...
-  MOCK_METHOD(void, Bar, (X* p));
-  ...
-  EXPECT_CALL(mock_foo_, Bar(_))
-      .WillOnce(Invoke(MyAction(...)));
-```
-
-### My code calls a static/global function. Can I mock it?
-
-You can, but you need to make some changes.
-
-In general, if you find yourself needing to mock a static function, it's a sign
-that your modules are too tightly coupled (and less flexible, less reusable,
-less testable, etc). You are probably better off defining a small interface and
-call the function through that interface, which then can be easily mocked. It's
-a bit of work initially, but usually pays for itself quickly.
-
-This Google Testing Blog
-[post](https://testing.googleblog.com/2008/06/defeat-static-cling.html) says it
-excellently. Check it out.
-
-### My mock object needs to do complex stuff. It's a lot of pain to specify the actions. gMock sucks!
-
-I know it's not a question, but you get an answer for free any way. :-)
-
-With gMock, you can create mocks in C++ easily. And people might be tempted to
-use them everywhere. Sometimes they work great, and sometimes you may find them,
-well, a pain to use. So, what's wrong in the latter case?
-
-When you write a test without using mocks, you exercise the code and assert that
-it returns the correct value or that the system is in an expected state. This is
-sometimes called "state-based testing".
-
-Mocks are great for what some call "interaction-based" testing: instead of
-checking the system state at the very end, mock objects verify that they are
-invoked the right way and report an error as soon as it arises, giving you a
-handle on the precise context in which the error was triggered. This is often
-more effective and economical to do than state-based testing.
-
-If you are doing state-based testing and using a test double just to simulate
-the real object, you are probably better off using a fake. Using a mock in this
-case causes pain, as it's not a strong point for mocks to perform complex
-actions. If you experience this and think that mocks suck, you are just not
-using the right tool for your problem. Or, you might be trying to solve the
-wrong problem. :-)
-
-### I got a warning "Uninteresting function call encountered - default action taken.." Should I panic?
-
-By all means, NO! It's just an FYI. :-)
-
-What it means is that you have a mock function, you haven't set any expectations
-on it (by gMock's rule this means that you are not interested in calls to this
-function and therefore it can be called any number of times), and it is called.
-That's OK - you didn't say it's not OK to call the function!
-
-What if you actually meant to disallow this function to be called, but forgot to
-write `EXPECT_CALL(foo, Bar()).Times(0)`? While one can argue that it's the
-user's fault, gMock tries to be nice and prints you a note.
-
-So, when you see the message and believe that there shouldn't be any
-uninteresting calls, you should investigate what's going on. To make your life
-easier, gMock dumps the stack trace when an uninteresting call is encountered.
-From that you can figure out which mock function it is, and how it is called.
-
-### I want to define a custom action. Should I use Invoke() or implement the ActionInterface interface?
-
-Either way is fine - you want to choose the one that's more convenient for your
-circumstance.
-
-Usually, if your action is for a particular function type, defining it using
-`Invoke()` should be easier; if your action can be used in functions of
-different types (e.g. if you are defining `Return(*value*)`),
-`MakePolymorphicAction()` is easiest. Sometimes you want precise control on what
-types of functions the action can be used in, and implementing `ActionInterface`
-is the way to go here. See the implementation of `Return()` in
-`testing/base/public/gmock-actions.h` for an example.
-
-### I use SetArgPointee() in WillOnce(), but gcc complains about "conflicting return type specified". What does it mean?
-
-You got this error as gMock has no idea what value it should return when the
-mock method is called. `SetArgPointee()` says what the side effect is, but
-doesn't say what the return value should be. You need `DoAll()` to chain a
-`SetArgPointee()` with a `Return()` that provides a value appropriate to the API
-being mocked.
-
-See this [recipe](cook_book.md#mocking-side-effects) for more details and an
-example.
-
-### I have a huge mock class, and Microsoft Visual C++ runs out of memory when compiling it. What can I do?
-
-We've noticed that when the `/clr` compiler flag is used, Visual C++ uses 5~6
-times as much memory when compiling a mock class. We suggest to avoid `/clr`
-when compiling native C++ mocks.

-// The ACTION* family of macros can be used in a namespace scope to
-// define custom actions easily.  The syntax:
-//
-//   ACTION(name) { statements; }
-//
-// will define an action with the given name that executes the
-// statements.  The value returned by the statements will be used as
-// the return value of the action.  Inside the statements, you can
-// refer to the K-th (0-based) argument of the mock function by
-// 'argK', and refer to its type by 'argK_type'.  For example:
-//
-//   ACTION(IncrementArg1) {
-//     arg1_type temp = arg1;
-//     return ++(*temp);
-//   }
-//
-// allows you to write
-//
-//   ...WillOnce(IncrementArg1());
-//
-// You can also refer to the entire argument tuple and its type by
-// 'args' and 'args_type', and refer to the mock function type and its
-// return type by 'function_type' and 'return_type'.
-//
-// Note that you don't need to specify the types of the mock function
-// arguments.  However rest assured that your code is still type-safe:
-// you'll get a compiler error if *arg1 doesn't support the ++
-// operator, or if the type of ++(*arg1) isn't compatible with the
-// mock function's return type, for example.
-//
-// Sometimes you'll want to parameterize the action.   For that you can use
-// another macro:
-//
-//   ACTION_P(name, param_name) { statements; }
-//
-// For example:
-//
-//   ACTION_P(Add, n) { return arg0 + n; }
-//
-// will allow you to write:
-//
-//   ...WillOnce(Add(5));
-//
-// Note that you don't need to provide the type of the parameter
-// either.  If you need to reference the type of a parameter named
-// 'foo', you can write 'foo_type'.  For example, in the body of
-// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
-// of 'n'.
-//
-// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P10 to support
-// multi-parameter actions.
-//
-// For the purpose of typing, you can view
-//
-//   ACTION_Pk(Foo, p1, ..., pk) { ... }
-//
-// as shorthand for
-//
-//   template <typename p1_type, ..., typename pk_type>
-//   FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
-//
-// In particular, you can provide the template type arguments
-// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
-// although usually you can rely on the compiler to infer the types
-// for you automatically.  You can assign the result of expression
-// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
-// pk_type>.  This can be useful when composing actions.
-//
-// You can also overload actions with different numbers of parameters:
-//
-//   ACTION_P(Plus, a) { ... }
-//   ACTION_P2(Plus, a, b) { ... }
-//
-// While it's tempting to always use the ACTION* macros when defining
-// a new action, you should also consider implementing ActionInterface
-// or using MakePolymorphicAction() instead, especially if you need to
-// use the action a lot.  While these approaches require more work,
-// they give you more control on the types of the mock function
-// arguments and the action parameters, which in general leads to
-// better compiler error messages that pay off in the long run.  They
-// also allow overloading actions based on parameter types (as opposed
-// to just based on the number of parameters).
-//
-// CAVEAT:
-//
-// ACTION*() can only be used in a namespace scope as templates cannot be
-// declared inside of a local class.
-// Users can, however, define any local functors (e.g. a lambda) that
-// can be used as actions.

-// Sometimes you want to give an action explicit template parameters
-// that cannot be inferred from its value parameters.  ACTION() and
-// ACTION_P*() don't support that.  ACTION_TEMPLATE() remedies that
-// and can be viewed as an extension to ACTION() and ACTION_P*().
-//
-// The syntax:
-//
-//   ACTION_TEMPLATE(ActionName,
-//                   HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
-//                   AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
-//
-// defines an action template that takes m explicit template
-// parameters and n value parameters.  name_i is the name of the i-th
-// template parameter, and kind_i specifies whether it's a typename,
-// an integral constant, or a template.  p_i is the name of the i-th
-// value parameter.
-//
-// Example:
-//
-//   // DuplicateArg<k, T>(output) converts the k-th argument of the mock
-//   // function to type T and copies it to *output.
-//   ACTION_TEMPLATE(DuplicateArg,
-//                   HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
-//                   AND_1_VALUE_PARAMS(output)) {
-//     *output = T(::std::get<k>(args));
-//   }
-//   ...
-//     int n;
-//     EXPECT_CALL(mock, Foo(_, _))
-//         .WillOnce(DuplicateArg<1, unsigned char>(&n));
-//
-// To create an instance of an action template, write:
-//
-//   ActionName<t1, ..., t_m>(v1, ..., v_n)
-//
-// where the ts are the template arguments and the vs are the value
-// arguments.  The value argument types are inferred by the compiler.
-// If you want to explicitly specify the value argument types, you can
-// provide additional template arguments:
-//
-//   ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
-//
-// where u_i is the desired type of v_i.
-//
-// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
-// number of value parameters, but not on the number of template
-// parameters.  Without the restriction, the meaning of the following
-// is unclear:
-//
-//   OverloadedAction<int, bool>(x);
-//
-// Are we using a single-template-parameter action where 'bool' refers
-// to the type of x, or are we using a two-template-parameter action
-// where the compiler is asked to infer the type of x?
-//
-// Implementation notes:
-//
-// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
-// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
-// implementing ACTION_TEMPLATE.  The main trick we use is to create
-// new macro invocations when expanding a macro.  For example, we have
-//
-//   #define ACTION_TEMPLATE(name, template_params, value_params)
-//       ... GMOCK_INTERNAL_DECL_##template_params ...
-//
-// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
-// to expand to
-//
-//       ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
-//
-// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
-// preprocessor will continue to expand it to
-//
-//       ... typename T ...
-//
-// This technique conforms to the C++ standard and is portable.  It
-// allows us to implement action templates using O(N) code, where N is
-// the maximum number of template/value parameters supported.  Without
-// using it, we'd have to devote O(N^2) amount of code to implement all
-// combinations of m and n.

-// Declares the template parameters.

-// Various overloads for InvokeArgument<N>().
-//
-// The InvokeArgument<N>(a1, a2, ..., a_k) action invokes the N-th
-// (0-based) argument, which must be a k-ary callable, of the mock
-// function, with arguments a1, a2, ..., a_k.
-//
-// Notes:
-//
-//   1. The arguments are passed by value by default.  If you need to
-//   pass an argument by reference, wrap it inside ByRef().  For
-//   example,
-//
-//     InvokeArgument<1>(5, string("Hello"), ByRef(foo))
-//
-//   passes 5 and string("Hello") by value, and passes foo by
-//   reference.
-//
-//   2. If the callable takes an argument by reference but ByRef() is
-//   not used, it will receive the reference to a copy of the value,
-//   instead of the original value.  For example, when the 0-th
-//   argument of the mock function takes a const string&, the action
-//
-//     InvokeArgument<0>(string("Hello"))
-//
-//   makes a copy of the temporary string("Hello") object and passes a
-//   reference of the copy, instead of the original temporary object,
-//   to the callable.  This makes it easy for a user to define an
-//   InvokeArgument action from temporary values and have it performed
-//   later.

-// The ACTION* family of macros can be used in a namespace scope to
-// define custom actions easily.  The syntax:
-//
-//   ACTION(name) { statements; }
-//
-// will define an action with the given name that executes the
-// statements.  The value returned by the statements will be used as
-// the return value of the action.  Inside the statements, you can
-// refer to the K-th (0-based) argument of the mock function by
-// 'argK', and refer to its type by 'argK_type'.  For example:
-//
-//   ACTION(IncrementArg1) {
-//     arg1_type temp = arg1;
-//     return ++(*temp);
-//   }
-//
-// allows you to write
-//
-//   ...WillOnce(IncrementArg1());
-//
-// You can also refer to the entire argument tuple and its type by
-// 'args' and 'args_type', and refer to the mock function type and its
-// return type by 'function_type' and 'return_type'.
-//
-// Note that you don't need to specify the types of the mock function
-// arguments.  However rest assured that your code is still type-safe:
-// you'll get a compiler error if *arg1 doesn't support the ++
-// operator, or if the type of ++(*arg1) isn't compatible with the
-// mock function's return type, for example.
-//
-// Sometimes you'll want to parameterize the action.   For that you can use
-// another macro:
-//
-//   ACTION_P(name, param_name) { statements; }
-//
-// For example:
-//
-//   ACTION_P(Add, n) { return arg0 + n; }
-//
-// will allow you to write:
-//
-//   ...WillOnce(Add(5));
-//
-// Note that you don't need to provide the type of the parameter
-// either.  If you need to reference the type of a parameter named
-// 'foo', you can write 'foo_type'.  For example, in the body of
-// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
-// of 'n'.
-//
-// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P$n to support
-// multi-parameter actions.
-//
-// For the purpose of typing, you can view
-//
-//   ACTION_Pk(Foo, p1, ..., pk) { ... }
-//
-// as shorthand for
-//
-//   template <typename p1_type, ..., typename pk_type>
-//   FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
-//
-// In particular, you can provide the template type arguments
-// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
-// although usually you can rely on the compiler to infer the types
-// for you automatically.  You can assign the result of expression
-// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
-// pk_type>.  This can be useful when composing actions.
-//
-// You can also overload actions with different numbers of parameters:
-//
-//   ACTION_P(Plus, a) { ... }
-//   ACTION_P2(Plus, a, b) { ... }
-//
-// While it's tempting to always use the ACTION* macros when defining
-// a new action, you should also consider implementing ActionInterface
-// or using MakePolymorphicAction() instead, especially if you need to
-// use the action a lot.  While these approaches require more work,
-// they give you more control on the types of the mock function
-// arguments and the action parameters, which in general leads to
-// better compiler error messages that pay off in the long run.  They
-// also allow overloading actions based on parameter types (as opposed
-// to just based on the number of parameters).
-//
-// CAVEAT:
-//
-// ACTION*() can only be used in a namespace scope as templates cannot be
-// declared inside of a local class.
-// Users can, however, define any local functors (e.g. a lambda) that
-// can be used as actions.
-//
-// MORE INFORMATION:

-// Sometimes you want to give an action explicit template parameters
-// that cannot be inferred from its value parameters.  ACTION() and
-// ACTION_P*() don't support that.  ACTION_TEMPLATE() remedies that
-// and can be viewed as an extension to ACTION() and ACTION_P*().
-//
-// The syntax:
-//
-//   ACTION_TEMPLATE(ActionName,
-//                   HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
-//                   AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
-//
-// defines an action template that takes m explicit template
-// parameters and n value parameters.  name_i is the name of the i-th
-// template parameter, and kind_i specifies whether it's a typename,
-// an integral constant, or a template.  p_i is the name of the i-th
-// value parameter.
-//
-// Example:
-//
-//   // DuplicateArg<k, T>(output) converts the k-th argument of the mock
-//   // function to type T and copies it to *output.
-//   ACTION_TEMPLATE(DuplicateArg,
-//                   HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
-//                   AND_1_VALUE_PARAMS(output)) {
-//     *output = T(::std::get<k>(args));
-//   }
-//   ...
-//     int n;
-//     EXPECT_CALL(mock, Foo(_, _))
-//         .WillOnce(DuplicateArg<1, unsigned char>(&n));
-//
-// To create an instance of an action template, write:
-//
-//   ActionName<t1, ..., t_m>(v1, ..., v_n)
-//
-// where the ts are the template arguments and the vs are the value
-// arguments.  The value argument types are inferred by the compiler.
-// If you want to explicitly specify the value argument types, you can
-// provide additional template arguments:
-//
-//   ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
-//
-// where u_i is the desired type of v_i.
-//
-// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
-// number of value parameters, but not on the number of template
-// parameters.  Without the restriction, the meaning of the following
-// is unclear:
-//
-//   OverloadedAction<int, bool>(x);
-//
-// Are we using a single-template-parameter action where 'bool' refers
-// to the type of x, or are we using a two-template-parameter action
-// where the compiler is asked to infer the type of x?
-//
-// Implementation notes:
-//
-// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
-// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
-// implementing ACTION_TEMPLATE.  The main trick we use is to create
-// new macro invocations when expanding a macro.  For example, we have
-//
-//   #define ACTION_TEMPLATE(name, template_params, value_params)
-//       ... GMOCK_INTERNAL_DECL_##template_params ...
-//
-// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
-// to expand to
-//
-//       ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
-//
-// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
-// preprocessor will continue to expand it to
-//
-//       ... typename T ...
-//
-// This technique conforms to the C++ standard and is portable.  It
-// allows us to implement action templates using O(N) code, where N is
-// the maximum number of template/value parameters supported.  Without
-// using it, we'd have to devote O(N^2) amount of code to implement all
-// combinations of m and n.

-// The InvokeArgument<N>(a1, a2, ..., a_k) action invokes the N-th
-// (0-based) argument, which must be a k-ary callable, of the mock
-// function, with arguments a1, a2, ..., a_k.
-//
-// Notes:
-//
-//   1. The arguments are passed by value by default.  If you need to
-//   pass an argument by reference, wrap it inside ByRef().  For
-//   example,
-//
-//     InvokeArgument<1>(5, string("Hello"), ByRef(foo))
-//
-//   passes 5 and string("Hello") by value, and passes foo by
-//   reference.
-//
-//   2. If the callable takes an argument by reference but ByRef() is
-//   not used, it will receive the reference to a copy of the value,
-//   instead of the original value.  For example, when the 0-th
-//   argument of the mock function takes a const string&, the action
-//
-//     InvokeArgument<0>(string("Hello"))
-//
-//   makes a copy of the temporary string("Hello") object and passes a
-//   reference of the copy, instead of the original temporary object,
-//   to the callable.  This makes it easy for a user to define an
-//   InvokeArgument action from temporary values and have it performed
-//   later.

-// The MATCHER* family of macros can be used in a namespace scope to
-// define custom matchers easily.
-//
-// Basic Usage
-// ===========
-//
-// The syntax
-//
-//   MATCHER(name, description_string) { statements; }
-//
-// defines a matcher with the given name that executes the statements,
-// which must return a bool to indicate if the match succeeds.  Inside
-// the statements, you can refer to the value being matched by 'arg',
-// and refer to its type by 'arg_type'.
-//
-// The description string documents what the matcher does, and is used
-// to generate the failure message when the match fails.  Since a
-// MATCHER() is usually defined in a header file shared by multiple
-// C++ source files, we require the description to be a C-string
-// literal to avoid possible side effects.  It can be empty, in which
-// case we'll use the sequence of words in the matcher name as the
-// description.
-//
-// For example:
-//
-//   MATCHER(IsEven, "") { return (arg % 2) == 0; }
-//
-// allows you to write
-//
-//   // Expects mock_foo.Bar(n) to be called where n is even.
-//   EXPECT_CALL(mock_foo, Bar(IsEven()));
-//
-// or,
-//
-//   // Verifies that the value of some_expression is even.
-//   EXPECT_THAT(some_expression, IsEven());
-//
-// If the above assertion fails, it will print something like:
-//
-//   Value of: some_expression
-//   Expected: is even
-//     Actual: 7
-//
-// where the description "is even" is automatically calculated from the
-// matcher name IsEven.
-//
-// Argument Type
-// =============
-//
-// Note that the type of the value being matched (arg_type) is
-// determined by the context in which you use the matcher and is
-// supplied to you by the compiler, so you don't need to worry about
-// declaring it (nor can you).  This allows the matcher to be
-// polymorphic.  For example, IsEven() can be used to match any type
-// where the value of "(arg % 2) == 0" can be implicitly converted to
-// a bool.  In the "Bar(IsEven())" example above, if method Bar()
-// takes an int, 'arg_type' will be int; if it takes an unsigned long,
-// 'arg_type' will be unsigned long; and so on.
-//
-// Parameterizing Matchers
-// =======================
-//
-// Sometimes you'll want to parameterize the matcher.  For that you
-// can use another macro:
-//
-//   MATCHER_P(name, param_name, description_string) { statements; }
-//
-// For example:
-//
-//   MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
-//
-// will allow you to write:
-//
-//   EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
-//
-// which may lead to this message (assuming n is 10):
-//
-//   Value of: Blah("a")
-//   Expected: has absolute value 10
-//     Actual: -9
-//
-// Note that both the matcher description and its parameter are
-// printed, making the message human-friendly.
-//
-// In the matcher definition body, you can write 'foo_type' to
-// reference the type of a parameter named 'foo'.  For example, in the
-// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
-// 'value_type' to refer to the type of 'value'.
-//
-// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P10 to
-// support multi-parameter matchers.
-//
-// Describing Parameterized Matchers
-// =================================
-//
-// The last argument to MATCHER*() is a string-typed expression.  The
-// expression can reference all of the matcher's parameters and a
-// special bool-typed variable named 'negation'.  When 'negation' is
-// false, the expression should evaluate to the matcher's description;
-// otherwise it should evaluate to the description of the negation of
-// the matcher.  For example,
-//
-//   using testing::PrintToString;
-//
-//   MATCHER_P2(InClosedRange, low, hi,
-//       std::string(negation ? "is not" : "is") + " in range [" +
-//       PrintToString(low) + ", " + PrintToString(hi) + "]") {
-//     return low <= arg && arg <= hi;
-//   }
-//   ...
-//   EXPECT_THAT(3, InClosedRange(4, 6));
-//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));
-//
-// would generate two failures that contain the text:
-//
-//   Expected: is in range [4, 6]
-//   ...
-//   Expected: is not in range [2, 4]
-//
-// If you specify "" as the description, the failure message will
-// contain the sequence of words in the matcher name followed by the
-// parameter values printed as a tuple.  For example,
-//
-//   MATCHER_P2(InClosedRange, low, hi, "") { ... }
-//   ...
-//   EXPECT_THAT(3, InClosedRange(4, 6));
-//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));
-//
-// would generate two failures that contain the text:
-//
-//   Expected: in closed range (4, 6)
-//   ...
-//   Expected: not (in closed range (2, 4))
-//
-// Types of Matcher Parameters
-// ===========================
-//
-// For the purpose of typing, you can view
-//
-//   MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
-//
-// as shorthand for
-//
-//   template <typename p1_type, ..., typename pk_type>
-//   FooMatcherPk<p1_type, ..., pk_type>
-//   Foo(p1_type p1, ..., pk_type pk) { ... }
-//
-// When you write Foo(v1, ..., vk), the compiler infers the types of
-// the parameters v1, ..., and vk for you.  If you are not happy with
-// the result of the type inference, you can specify the types by
-// explicitly instantiating the template, as in Foo<long, bool>(5,
-// false).  As said earlier, you don't get to (or need to) specify
-// 'arg_type' as that's determined by the context in which the matcher
-// is used.  You can assign the result of expression Foo(p1, ..., pk)
-// to a variable of type FooMatcherPk<p1_type, ..., pk_type>.  This
-// can be useful when composing matchers.
-//
-// While you can instantiate a matcher template with reference types,
-// passing the parameters by pointer usually makes your code more
-// readable.  If, however, you still want to pass a parameter by
-// reference, be aware that in the failure message generated by the
-// matcher you will see the value of the referenced object but not its
-// address.
-//
-// Explaining Match Results
-// ========================
-//
-// Sometimes the matcher description alone isn't enough to explain why
-// the match has failed or succeeded.  For example, when expecting a
-// long string, it can be very helpful to also print the diff between
-// the expected string and the actual one.  To achieve that, you can
-// optionally stream additional information to a special variable
-// named result_listener, whose type is a pointer to class
-// MatchResultListener:
-//
-//   MATCHER_P(EqualsLongString, str, "") {
-//     if (arg == str) return true;
-//
-//     *result_listener << "the difference: "
-///                     << DiffStrings(str, arg);
-//     return false;
-//   }
-//
-// Overloading Matchers
-// ====================
-//
-// You can overload matchers with different numbers of parameters:
-//
-//   MATCHER_P(Blah, a, description_string1) { ... }
-//   MATCHER_P2(Blah, a, b, description_string2) { ... }
-//
-// Caveats
-// =======
-//
-// When defining a new matcher, you should also consider implementing
-// MatcherInterface or using MakePolymorphicMatcher().  These
-// approaches require more work than the MATCHER* macros, but also
-// give you more control on the types of the value being matched and
-// the matcher parameters, which may leads to better compiler error
-// messages when the matcher is used wrong.  They also allow
-// overloading matchers based on parameter types (as opposed to just
-// based on the number of parameters).
-//
-// MATCHER*() can only be used in a namespace scope as templates cannot be
-// declared inside of a local class.
-//

-// The MATCHER* family of macros can be used in a namespace scope to
-// define custom matchers easily.
-//
-// Basic Usage
-// ===========
-//
-// The syntax
-//
-//   MATCHER(name, description_string) { statements; }
-//
-// defines a matcher with the given name that executes the statements,
-// which must return a bool to indicate if the match succeeds.  Inside
-// the statements, you can refer to the value being matched by 'arg',
-// and refer to its type by 'arg_type'.
-//
-// The description string documents what the matcher does, and is used
-// to generate the failure message when the match fails.  Since a
-// MATCHER() is usually defined in a header file shared by multiple
-// C++ source files, we require the description to be a C-string
-// literal to avoid possible side effects.  It can be empty, in which
-// case we'll use the sequence of words in the matcher name as the
-// description.
-//
-// For example:
-//
-//   MATCHER(IsEven, "") { return (arg % 2) == 0; }
-//
-// allows you to write
-//
-//   // Expects mock_foo.Bar(n) to be called where n is even.
-//   EXPECT_CALL(mock_foo, Bar(IsEven()));
-//
-// or,
-//
-//   // Verifies that the value of some_expression is even.
-//   EXPECT_THAT(some_expression, IsEven());
-//
-// If the above assertion fails, it will print something like:
-//
-//   Value of: some_expression
-//   Expected: is even
-//     Actual: 7
-//
-// where the description "is even" is automatically calculated from the
-// matcher name IsEven.
-//
-// Argument Type
-// =============
-//
-// Note that the type of the value being matched (arg_type) is
-// determined by the context in which you use the matcher and is
-// supplied to you by the compiler, so you don't need to worry about
-// declaring it (nor can you).  This allows the matcher to be
-// polymorphic.  For example, IsEven() can be used to match any type
-// where the value of "(arg % 2) == 0" can be implicitly converted to
-// a bool.  In the "Bar(IsEven())" example above, if method Bar()
-// takes an int, 'arg_type' will be int; if it takes an unsigned long,
-// 'arg_type' will be unsigned long; and so on.
-//
-// Parameterizing Matchers
-// =======================
-//
-// Sometimes you'll want to parameterize the matcher.  For that you
-// can use another macro:
-//
-//   MATCHER_P(name, param_name, description_string) { statements; }
-//
-// For example:
-//
-//   MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
-//
-// will allow you to write:
-//
-//   EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
-//
-// which may lead to this message (assuming n is 10):
-//
-//   Value of: Blah("a")
-//   Expected: has absolute value 10
-//     Actual: -9
-//
-// Note that both the matcher description and its parameter are
-// printed, making the message human-friendly.
-//
-// In the matcher definition body, you can write 'foo_type' to
-// reference the type of a parameter named 'foo'.  For example, in the
-// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
-// 'value_type' to refer to the type of 'value'.
-//
-// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P$n to
-// support multi-parameter matchers.
-//
-// Describing Parameterized Matchers
-// =================================
-//
-// The last argument to MATCHER*() is a string-typed expression.  The
-// expression can reference all of the matcher's parameters and a
-// special bool-typed variable named 'negation'.  When 'negation' is
-// false, the expression should evaluate to the matcher's description;
-// otherwise it should evaluate to the description of the negation of
-// the matcher.  For example,
-//
-//   using testing::PrintToString;
-//
-//   MATCHER_P2(InClosedRange, low, hi,

-//   Expected: not (in closed range (2, 4))
-//
-// Types of Matcher Parameters
-// ===========================
-//
-// For the purpose of typing, you can view
-//
-//   MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
-//
-// as shorthand for
-//
-//   template <typename p1_type, ..., typename pk_type>
-//   FooMatcherPk<p1_type, ..., pk_type>
-//   Foo(p1_type p1, ..., pk_type pk) { ... }
-//
-// When you write Foo(v1, ..., vk), the compiler infers the types of
-// the parameters v1, ..., and vk for you.  If you are not happy with
-// the result of the type inference, you can specify the types by
-// explicitly instantiating the template, as in Foo<long, bool>(5,
-// false).  As said earlier, you don't get to (or need to) specify
-// 'arg_type' as that's determined by the context in which the matcher
-// is used.  You can assign the result of expression Foo(p1, ..., pk)
-// to a variable of type FooMatcherPk<p1_type, ..., pk_type>.  This
-// can be useful when composing matchers.
-//
-// While you can instantiate a matcher template with reference types,
-// passing the parameters by pointer usually makes your code more
-// readable.  If, however, you still want to pass a parameter by
-// reference, be aware that in the failure message generated by the
-// matcher you will see the value of the referenced object but not its
-// address.
-//
-// Explaining Match Results
-// ========================
-//
-// Sometimes the matcher description alone isn't enough to explain why
-// the match has failed or succeeded.  For example, when expecting a
-// long string, it can be very helpful to also print the diff between
-// the expected string and the actual one.  To achieve that, you can
-// optionally stream additional information to a special variable
-// named result_listener, whose type is a pointer to class
-// MatchResultListener:
-//
-//   MATCHER_P(EqualsLongString, str, "") {
-//     if (arg == str) return true;
-//
-//     *result_listener << "the difference: "
-///                     << DiffStrings(str, arg);
-//     return false;
-//   }
-//
-// Overloading Matchers
-// ====================
-//
-// You can overload matchers with different numbers of parameters:
-//
-//   MATCHER_P(Blah, a, description_string1) { ... }
-//   MATCHER_P2(Blah, a, b, description_string2) { ... }
-//
-// Caveats
-// =======
-//
-// When defining a new matcher, you should also consider implementing
-// MatcherInterface or using MakePolymorphicMatcher().  These
-// approaches require more work than the MATCHER* macros, but also
-// give you more control on the types of the value being matched and
-// the matcher parameters, which may leads to better compiler error
-// messages when the matcher is used wrong.  They also allow
-// overloading matchers based on parameter types (as opposed to just
-// based on the number of parameters).
-//
-// MATCHER*() can only be used in a namespace scope as templates cannot be
-// declared inside of a local class.
-//
-// More Information
-// ================

-// Implements class templates NiceMock, NaggyMock, and StrictMock.
-//
-// Given a mock class MockFoo that is created using Google Mock,
-// NiceMock<MockFoo> is a subclass of MockFoo that allows
-// uninteresting calls (i.e. calls to mock methods that have no
-// EXPECT_CALL specs), NaggyMock<MockFoo> is a subclass of MockFoo
-// that prints a warning when an uninteresting call occurs, and
-// StrictMock<MockFoo> is a subclass of MockFoo that treats all
-// uninteresting calls as errors.
-//
-// Currently a mock is naggy by default, so MockFoo and
-// NaggyMock<MockFoo> behave like the same.  However, we will soon
-// switch the default behavior of mocks to be nice, as that in general
-// leads to more maintainable tests.  When that happens, MockFoo will
-// stop behaving like NaggyMock<MockFoo> and start behaving like
-// NiceMock<MockFoo>.
-//
-// NiceMock, NaggyMock, and StrictMock "inherit" the constructors of
-// their respective base class.  Therefore you can write
-// NiceMock<MockFoo>(5, "a") to construct a nice mock where MockFoo
-// has a constructor that accepts (int, const char*), for example.
-//
-// A known limitation is that NiceMock<MockFoo>, NaggyMock<MockFoo>,
-// and StrictMock<MockFoo> only works for mock methods defined using
-// the MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.
-// If a mock method is defined in a base class of MockFoo, the "nice"
-// or "strict" modifier may not affect it, depending on the compiler.
-// In particular, nesting NiceMock, NaggyMock, and StrictMock is NOT
-// supported.

-// Google Mock - a framework for writing C++ mock classes.

-// This file implements the ON_CALL() and EXPECT_CALL() macros.
-//
-// A user can use the ON_CALL() macro to specify the default action of
-// a mock method.  The syntax is:
-//
-//   ON_CALL(mock_object, Method(argument-matchers))
-//       .With(multi-argument-matcher)
-//       .WillByDefault(action);
-//
-//  where the .With() clause is optional.
-//
-// A user can use the EXPECT_CALL() macro to specify an expectation on
-// a mock method.  The syntax is:
-//
-//   EXPECT_CALL(mock_object, Method(argument-matchers))
-//       .With(multi-argument-matchers)
-//       .Times(cardinality)
-//       .InSequence(sequences)
-//       .After(expectations)
-//       .WillOnce(action)
-//       .WillRepeatedly(action)
-//       .RetiresOnSaturation();
-//
-// where all clauses are optional, and .InSequence()/.After()/
-// .WillOnce() can appear any number of times.

-// A MockFunction<F> class has one mock method whose type is F.  It is
-// useful when you just want your test code to emit some messages and
-// have Google Mock verify the right messages are sent (and perhaps at
-// the right times).  For example, if you are exercising code:
-//
-//   Foo(1);
-//   Foo(2);
-//   Foo(3);
-//
-// and want to verify that Foo(1) and Foo(3) both invoke
-// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
-//
-// TEST(FooTest, InvokesBarCorrectly) {
-//   MyMock mock;
-//   MockFunction<void(string check_point_name)> check;
-//   {
-//     InSequence s;
-//
-//     EXPECT_CALL(mock, Bar("a"));
-//     EXPECT_CALL(check, Call("1"));
-//     EXPECT_CALL(check, Call("2"));
-//     EXPECT_CALL(mock, Bar("a"));
-//   }
-//   Foo(1);
-//   check.Call("1");
-//   Foo(2);
-//   check.Call("2");
-//   Foo(3);
-// }
-//
-// The expectation spec says that the first Bar("a") must happen
-// before check point "1", the second Bar("a") must happen after check
-// point "2", and nothing should happen between the two check
-// points. The explicit check points make it easy to tell which
-// Bar("a") is called by which call to Foo().
-//
-// MockFunction<F> can also be used to exercise code that accepts
-// std::function<F> callbacks. To do so, use AsStdFunction() method
-// to create std::function proxy forwarding to original object's Call.
-// Example:
-//
-// TEST(FooTest, RunsCallbackWithBarArgument) {
-//   MockFunction<int(string)> callback;
-//   EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
-//   Foo(callback.AsStdFunction());

-// Implementation for ON_CALL and EXPECT_CALL macros. A separate macro is
-// required to avoid compile errors when the name of the method used in call is
-// a result of macro expansion. See CompilesWithMethodNameExpandedFromMacro
-// tests in internal/gmock-spec-builders_test.cc for more details.
-//
-// This macro supports statements both with and without parameter matchers. If
-// the parameter list is omitted, gMock will accept any parameters, which allows
-// tests to be written that don't need to encode the number of method
-// parameter. This technique may only be used for non-overloaded methods.
-//
-//   // These are the same:
-//   ON_CALL(mock, NoArgsMethod()).WillByDefault(...);
-//   ON_CALL(mock, NoArgsMethod).WillByDefault(...);
-//
-//   // As are these:
-//   ON_CALL(mock, TwoArgsMethod(_, _)).WillByDefault(...);
-//   ON_CALL(mock, TwoArgsMethod).WillByDefault(...);
-//
-//   // Can also specify args if you want, of course:
-//   ON_CALL(mock, TwoArgsMethod(_, 45)).WillByDefault(...);
-//
-//   // Overloads work as long as you specify parameters:
-//   ON_CALL(mock, OverloadedMethod(_)).WillByDefault(...);
-//   ON_CALL(mock, OverloadedMethod(_, _)).WillByDefault(...);
-//
-//   // Oops! Which overload did you want?
-//   ON_CALL(mock, OverloadedMethod).WillByDefault(...);
-//     => ERROR: call to member function 'gmock_OverloadedMethod' is ambiguous
-//
-// How this works: The mock class uses two overloads of the gmock_Method
-// expectation setter method plus an operator() overload on the MockSpec object.
-// In the matcher list form, the macro expands to:
-//
-//   // This statement:
-//   ON_CALL(mock, TwoArgsMethod(_, 45))...
-//
-//   // ...expands to:
-//   mock.gmock_TwoArgsMethod(_, 45)(WithoutMatchers(), nullptr)...
-//   |-------------v---------------||------------v-------------|
-//       invokes first overload        swallowed by operator()
-//
-//   // ...which is essentially:
-//   mock.gmock_TwoArgsMethod(_, 45)...
-//
-// Whereas the form without a matcher list:
-//
-//   // This statement:
-//   ON_CALL(mock, TwoArgsMethod)...
-//
-//   // ...expands to:
-//   mock.gmock_TwoArgsMethod(WithoutMatchers(), nullptr)...
-//   |-----------------------v--------------------------|
-//                 invokes second overload
-//
-//   // ...which is essentially:
-//   mock.gmock_TwoArgsMethod(_, _)...
-//
-// The WithoutMatchers() argument is used to disambiguate overloads and to
-// block the caller from accidentally invoking the second overload directly. The
-// second argument is an internal type derived from the method signature. The
-// failure to disambiguate two overloads of this method in the ON_CALL statement
-// is how we block callers from setting expectations on overloaded methods.

-"""fuse_gmock_files.py v0.1.0
-Fuses Google Mock and Google Test source code into two .h files and a .cc file.
-
-SYNOPSIS
-       fuse_gmock_files.py [GMOCK_ROOT_DIR] OUTPUT_DIR
-
-       Scans GMOCK_ROOT_DIR for Google Mock and Google Test source
-       code, assuming Google Test is in the GMOCK_ROOT_DIR/../googletest
-       directory, and generates three files:
-       OUTPUT_DIR/gtest/gtest.h, OUTPUT_DIR/gmock/gmock.h, and
-       OUTPUT_DIR/gmock-gtest-all.cc.  Then you can build your tests
-       by adding OUTPUT_DIR to the include search path and linking
-       with OUTPUT_DIR/gmock-gtest-all.cc.  These three files contain
-       everything you need to use Google Mock.  Hence you can
-       "install" Google Mock by copying them to wherever you want.
-
-       GMOCK_ROOT_DIR can be omitted and defaults to the parent
-       directory of the directory holding this script.
-
-EXAMPLES
-       ./fuse_gmock_files.py fused_gmock
-       ./fuse_gmock_files.py path/to/unpacked/gmock fused_gmock
-
-This tool is experimental.  In particular, it assumes that there is no
-conditional inclusion of Google Mock or Google Test headers.  Please
-report any problems to googlemock@googlegroups.com.  You can read
-https://github.com/google/googletest/blob/master/googlemock/docs/cook_book.md for more
-information.

-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing

-
-The Google Mock class generator is an application that is part of cppclean.
-For more information about cppclean, visit http://code.google.com/p/cppclean/
-
-The mock generator requires Python 2.3.5 or later.  If you don't have Python
-installed on your system, you will also need to install it.  You can download
-Python from:  http://www.python.org/download/releases/
-
-To use the Google Mock class generator, you need to call it
-on the command line passing the header file and class for which you want
-to generate a Google Mock class.
-
-Make sure to install the scripts somewhere in your path.  Then you can
-run the program.
-
-  gmock_gen.py header-file.h [ClassName]...
-
-If no ClassNames are specified, all classes in the file are emitted.
-
-To change the indentation from the default of 2, set INDENT in
-the environment.  For example to use an indent of 4 spaces:
-
-INDENT=4 gmock_gen.py header-file.h ClassName
-
-This version was made from SVN revision 281 in the cppclean repository.
-
-Known Limitations
------------------
-Not all code will be generated properly.  For example, when mocking templated
-classes, the template information is lost.  You will need to add the template
-information manually.
-
-Not all permutations of using multiple pointers/references will be rendered
-properly.  These will also have to be fixed manually.

-Goal:
------
-  CppClean attempts to find problems in C++ source that slow development
-  in large code bases, for example various forms of unused code.
-  Unused code can be unused functions, methods, data members, types, etc
-  to unnecessary #include directives.  Unnecessary #includes can cause
-  considerable extra compiles increasing the edit-compile-run cycle.
-
-  The project home page is:   http://code.google.com/p/cppclean/
-
-
-Features:
----------
- * Find and print C++ language constructs: classes, methods, functions, etc.
- * Find classes with virtual methods, no virtual destructor, and no bases
- * Find global/static data that are potential problems when using threads
- * Unnecessary forward class declarations
- * Unnecessary function declarations
- * Undeclared function definitions
- * (planned) Find unnecessary header files #included
-   - No direct reference to anything in the header
-   - Header is unnecessary if classes were forward declared instead
- * (planned) Source files that reference headers not directly #included,
-   ie, files that rely on a transitive #include from another header
- * (planned) Unused members (private, protected, & public) methods and data
- * (planned) Store AST in a SQL database so relationships can be queried
-
-AST is Abstract Syntax Tree, a representation of parsed source code.
-http://en.wikipedia.org/wiki/Abstract_syntax_tree
-
-
-System Requirements:
---------------------
- * Python 2.4 or later (2.3 probably works too)
- * Works on Windows (untested), Mac OS X, and Unix
-
-
-How to Run:
------------
-  For all examples, it is assumed that cppclean resides in a directory called
-  /cppclean.
-
-  To print warnings for classes with virtual methods, no virtual destructor and
-  no base classes:
-
-      /cppclean/run.sh nonvirtual_dtors.py file1.h file2.h file3.cc ...
-
-  To print all the functions defined in header file(s):
-
-      /cppclean/run.sh functions.py file1.h file2.h ...
-
-  All the commands take multiple files on the command line.  Other programs
-  include: find_warnings, headers, methods, and types.  Some other programs
-  are available, but used primarily for debugging.
-
-  run.sh is a simple wrapper that sets PYTHONPATH to /cppclean and then
-  runs the program in /cppclean/cpp/PROGRAM.py.  There is currently
-  no equivalent for Windows.  Contributions for a run.bat file
-  would be greatly appreciated.
-
-
-How to Configure:
------------------
-  You can add a siteheaders.py file in /cppclean/cpp to configure where
-  to look for other headers (typically -I options passed to a compiler).
-  Currently two values are supported:  _TRANSITIVE and GetIncludeDirs.
-  _TRANSITIVE should be set to a boolean value (True or False) indicating
-  whether to transitively process all header files.  The default is False.
-
-  GetIncludeDirs is a function that takes a single argument and returns
-  a sequence of directories to include.  This can be a generator or
-  return a static list.
-
-      def GetIncludeDirs(filename):
-          return ['/some/path/with/other/headers']
-
-      # Here is a more complicated example.
-      def GetIncludeDirs(filename):
-          yield '/path1'
-          yield os.path.join('/path2', os.path.dirname(filename))
-          yield '/path3'
-
-
-How to Test:
-------------
-  For all examples, it is assumed that cppclean resides in a directory called
-  /cppclean.  The tests require
-
-  cd /cppclean
-  make test
-  # To generate expected results after a change:
-  make expected
-
-
-Current Status:
----------------
-  The parser works pretty well for header files, parsing about 99% of Google's
-  header files.  Anything which inspects structure of C++ source files should
-  work reasonably well.  Function bodies are not transformed to an AST,
-  but left as tokens.  Much work is still needed on finding unused header files
-  and storing an AST in a database.
-
-
-Non-goals:
-----------
- * Parsing all valid C++ source
- * Handling invalid C++ source gracefully
- * Compiling to machine code (or anything beyond an AST)
-

-The `gmock-config' script provides access to the necessary compile and linking
-flags to connect with Google C++ Mocking Framework, both in a build prior to
-installation, and on the system proper after installation. The installation
-overrides may be issued in combination with any other queries, but will only
-affect installation queries if called on a built but not installed gmock. The
-installation queries may not be issued with any other types of queries, and
-only one installation query may be made at a time. The version queries and
-compiler flag queries may be combined as desired but not mixed. Different
-version queries are always combined with logical "and" semantics, and only the
-last of any particular query is used while all previous ones ignored. All
-versions must be specified as a sequence of numbers separated by periods.
-Compiler flag queries output the union of the sets of flags when combined.
-
- Examples:
-  gmock-config --min-version=1.0 || echo "Insufficient Google Mock version."
-
-  g++ $(gmock-config --cppflags --cxxflags) -o foo.o -c foo.cpp
-  g++ $(gmock-config --ldflags --libs) -o foo foo.o
-
-  # When using a built but not installed Google Mock:
-  g++ $(../../my_gmock_build/scripts/gmock-config ...) ...
-
-  # When using an installed Google Mock, but with installation overrides:
-  export GMOCK_PREFIX="/opt"
-  g++ $(gmock-config --libdir="/opt/lib64" ...) ...
-
- Help:
-  --usage                    brief usage information
-  --help                     display this help message
-
- Installation Overrides:
-  --prefix=<dir>             overrides the installation prefix
-  --exec-prefix=<dir>        overrides the executable installation prefix
-  --libdir=<dir>             overrides the library installation prefix
-  --includedir=<dir>         overrides the header file installation prefix
-
- Installation Queries:
-  --prefix                   installation prefix
-  --exec-prefix              executable installation prefix
-  --libdir                   library installation directory
-  --includedir               header file installation directory
-  --version                  the version of the Google Mock installation
-
- Version Queries:
-  --min-version=VERSION      return 0 if the version is at least VERSION
-  --exact-version=VERSION    return 0 if the version is exactly VERSION
-  --max-version=VERSION      return 0 if the version is at most VERSION
-
- Compilation Flag Queries:
-  --cppflags                 compile flags specific to the C-like preprocessors
-  --cxxflags                 compile flags appropriate for C++ programs

-// FindMaxBipartiteMatching and its helper class.
-//
-// Uses the well-known Ford-Fulkerson max flow method to find a maximum
-// bipartite matching. Flow is considered to be from left to right.
-// There is an implicit source node that is connected to all of the left
-// nodes, and an implicit sink node that is connected to all of the
-// right nodes. All edges have unit capacity.
-//
-// Neither the flow graph nor the residual flow graph are represented
-// explicitly. Instead, they are implied by the information in 'graph' and
-// a vector<int> called 'left_' whose elements are initialized to the
-// value kUnused. This represents the initial state of the algorithm,
-// where the flow graph is empty, and the residual flow graph has the
-// following edges:
-//   - An edge from source to each left_ node
-//   - An edge from each right_ node to sink
-//   - An edge from each left_ node to each right_ node, if the
-//     corresponding edge exists in 'graph'.
-//
-// When the TryAugment() method adds a flow, it sets left_[l] = r for some
-// nodes l and r. This induces the following changes:
-//   - The edges (source, l), (l, r), and (r, sink) are added to the
-//     flow graph.
-//   - The same three edges are removed from the residual flow graph.
-//   - The reverse edges (l, source), (r, l), and (sink, r) are added
-//     to the residual flow graph, which is a directional graph
-//     representing unused flow capacity.
-//
-// When the method augments a flow (moving left_[l] from some r1 to some
-// other r2), this can be thought of as "undoing" the above steps with
-// respect to r1 and "redoing" them with respect to r2.

-// Google Mock - a framework for writing C++ mock classes.

-// This file tests that:
-// a. A header file defining a mock class can be included in multiple
-//    translation units without causing a link error.
-// b. Actions and matchers can be instantiated with identical template
-//    arguments in different translation units without causing link
-//    errors.
-//    The following constructs are currently tested:
-//    Actions:
-//      Return()
-//      Return(value)
-//      ReturnNull
-//      ReturnRef
-//      Assign
-//      SetArgPointee
-//      SetArrayArgument
-//      SetErrnoAndReturn
-//      Invoke(function)
-//      Invoke(object, method)
-//      InvokeWithoutArgs(function)
-//      InvokeWithoutArgs(object, method)
-//      InvokeArgument
-//      WithArg
-//      WithArgs
-//      WithoutArgs

-//      Eq
-//      Gt, Lt, Ge, Le, Ne

-//      AllOf
-//      AnyOf
-//      Not
-//      MatcherCast<T>
-//
-//  Please note: this test does not verify the functioning of these
-//  constructs, only that the programs using them will link successfully.
-//
-// Implementation note:
-// This test requires identical definitions of Interface and Mock to be
-// included in different translation units.  We achieve this by writing
-// them in this header and #including it in gmock_link_test.cc and
-// gmock_link2_test.cc.  Because the symbols generated by the compiler for
-// those constructs must be identical in both translation units,
-// definitions of Interface and Mock tests MUST be kept in the SAME
-// NON-ANONYMOUS namespace in this file.  The test fixture class LinkTest
-// is defined as LinkTest1 in gmock_link_test.cc and as LinkTest2 in
-// gmock_link2_test.cc to avoid producing linker errors.

-ERROR: 3 leaked mock objects found at program exit. Expectations on a mock object is verified when the object is destructed. Leaking a mock means that its expectations aren't verified, which is usually a test bug. If you really intend to leak a mock, you can suppress this error using testing::Mock::AllowLeak(mock_object), or you may use a fake or stub instead of a mock.

-### Generic Build Instructions
-
-#### Setup
-
-To build Google Test and your tests that use it, you need to tell your build
-system where to find its headers and source files. The exact way to do it
-depends on which build system you use, and is usually straightforward.
-
-### Build with CMake
-
-Google Test comes with a CMake build script (
-[CMakeLists.txt](https://github.com/google/googletest/blob/master/CMakeLists.txt))
-that can be used on a wide range of platforms ("C" stands for cross-platform.).
-If you don't have CMake installed already, you can download it for free from
-<http://www.cmake.org/>.
-
-CMake works by generating native makefiles or build projects that can be used in
-the compiler environment of your choice. You can either build Google Test as a
-standalone project or it can be incorporated into an existing CMake build for
-another project.
-
-#### Standalone CMake Project
-
-When building Google Test as a standalone project, the typical workflow starts
-with:
-
-    mkdir mybuild       # Create a directory to hold the build output.
-    cd mybuild
-    cmake ${GTEST_DIR}  # Generate native build scripts.
-
-If you want to build Google Test's samples, you should replace the last command
-with
-
-    cmake -Dgtest_build_samples=ON ${GTEST_DIR}
-
-If you are on a \*nix system, you should now see a Makefile in the current
-directory. Just type 'make' to build gtest.
-
-If you use Windows and have Visual Studio installed, a `gtest.sln` file and
-several `.vcproj` files will be created. You can then build them using Visual
-Studio.
-
-On Mac OS X with Xcode installed, a `.xcodeproj` file will be generated.
-
-#### Incorporating Into An Existing CMake Project
-
-If you want to use gtest in a project which already uses CMake, then a more
-robust and flexible approach is to build gtest as part of that project directly.
-This is done by making the GoogleTest source code available to the main build
-and adding it using CMake's `add_subdirectory()` command. This has the
-significant advantage that the same compiler and linker settings are used
-between gtest and the rest of your project, so issues associated with using
-incompatible libraries (eg debug/release), etc. are avoided. This is
-particularly useful on Windows. Making GoogleTest's source code available to the
-main build can be done a few different ways:
-
-*   Download the GoogleTest source code manually and place it at a known
-    location. This is the least flexible approach and can make it more difficult
-    to use with continuous integration systems, etc.
-*   Embed the GoogleTest source code as a direct copy in the main project's
-    source tree. This is often the simplest approach, but is also the hardest to
-    keep up to date. Some organizations may not permit this method.
-*   Add GoogleTest as a git submodule or equivalent. This may not always be
-    possible or appropriate. Git submodules, for example, have their own set of
-    advantages and drawbacks.
-*   Use CMake to download GoogleTest as part of the build's configure step. This
-    is just a little more complex, but doesn't have the limitations of the other
-    methods.
-
-The last of the above methods is implemented with a small piece of CMake code in
-a separate file (e.g. `CMakeLists.txt.in`) which is copied to the build area and
-then invoked as a sub-build _during the CMake stage_. That directory is then
-pulled into the main build with `add_subdirectory()`. For example:
-
-New file `CMakeLists.txt.in`:
-
-```cmake
-cmake_minimum_required(VERSION 2.8.2)
-
-project(googletest-download NONE)
-
-include(ExternalProject)
-ExternalProject_Add(googletest
-  GIT_REPOSITORY    https://github.com/google/googletest.git
-  GIT_TAG           master
-  SOURCE_DIR        "${CMAKE_CURRENT_BINARY_DIR}/googletest-src"
-  BINARY_DIR        "${CMAKE_CURRENT_BINARY_DIR}/googletest-build"
-  CONFIGURE_COMMAND ""
-  BUILD_COMMAND     ""
-  INSTALL_COMMAND   ""
-  TEST_COMMAND      ""
-)
-```
-
-Existing build's `CMakeLists.txt`:
-
-```cmake
-# Download and unpack googletest at configure time
-configure_file(CMakeLists.txt.in googletest-download/CMakeLists.txt)
-execute_process(COMMAND ${CMAKE_COMMAND} -G "${CMAKE_GENERATOR}" .
-  RESULT_VARIABLE result
-  WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/googletest-download )
-if(result)
-  message(FATAL_ERROR "CMake step for googletest failed: ${result}")
-endif()
-execute_process(COMMAND ${CMAKE_COMMAND} --build .
-  RESULT_VARIABLE result
-  WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/googletest-download )
-if(result)
-  message(FATAL_ERROR "Build step for googletest failed: ${result}")
-endif()
-
-# Prevent overriding the parent project's compiler/linker
-# settings on Windows
-set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
-
-# Add googletest directly to our build. This defines
-# the gtest and gtest_main targets.
-add_subdirectory(${CMAKE_CURRENT_BINARY_DIR}/googletest-src
-                 ${CMAKE_CURRENT_BINARY_DIR}/googletest-build
-                 EXCLUDE_FROM_ALL)
-
-# The gtest/gtest_main targets carry header search path
-# dependencies automatically when using CMake 2.8.11 or
-# later. Otherwise we have to add them here ourselves.
-if (CMAKE_VERSION VERSION_LESS 2.8.11)
-  include_directories("${gtest_SOURCE_DIR}/include")
-endif()
-
-# Now simply link against gtest or gtest_main as needed. Eg
-add_executable(example example.cpp)
-target_link_libraries(example gtest_main)
-add_test(NAME example_test COMMAND example)
-```
-
-Note that this approach requires CMake 2.8.2 or later due to its use of the
-`ExternalProject_Add()` command. The above technique is discussed in more detail
-in [this separate article](http://crascit.com/2015/07/25/cmake-gtest/) which
-also contains a link to a fully generalized implementation of the technique.
-
-##### Visual Studio Dynamic vs Static Runtimes
-
-By default, new Visual Studio projects link the C runtimes dynamically but
-Google Test links them statically. This will generate an error that looks
-something like the following: gtest.lib(gtest-all.obj) : error LNK2038: mismatch
-detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value
-'MDd_DynamicDebug' in main.obj
-
-Google Test already has a CMake option for this: `gtest_force_shared_crt`
-
-Enabling this option will make gtest link the runtimes dynamically too, and
-match the project in which it is included.
-
-#### C++ Standard Version
-
-An environment that supports C++11 is required in order to successfully build
-Google Test. One way to ensure this is to specify the standard in the top-level
-project, for example by using the `set(CMAKE_CXX_STANDARD 11)` command. If this
-is not feasible, for example in a C project using Google Test for validation,
-then it can be specified by adding it to the options for cmake via the
-`DCMAKE_CXX_FLAGS` option.
-
-### Tweaking Google Test
-
-Google Test can be used in diverse environments. The default configuration may
-not work (or may not work well) out of the box in some environments. However,
-you can easily tweak Google Test by defining control macros on the compiler
-command line. Generally, these macros are named like `GTEST_XYZ` and you define
-them to either 1 or 0 to enable or disable a certain feature.
-
-We list the most frequently used macros below. For a complete list, see file
-[include/gtest/internal/gtest-port.h](https://github.com/google/googletest/blob/master/googletest/include/gtest/internal/gtest-port.h).
-
-### Multi-threaded Tests
-
-Google Test is thread-safe where the pthread library is available. After
-`#include "gtest/gtest.h"`, you can check the
-`GTEST_IS_THREADSAFE` macro to see whether this is the case (yes if the macro is
-`#defined` to 1, no if it's undefined.).
-
-If Google Test doesn't correctly detect whether pthread is available in your
-environment, you can force it with
-
-    -DGTEST_HAS_PTHREAD=1
-
-or
-
-    -DGTEST_HAS_PTHREAD=0
-
-When Google Test uses pthread, you may need to add flags to your compiler and/or
-linker to select the pthread library, or you'll get link errors. If you use the
-CMake script or the deprecated Autotools script, this is taken care of for you.
-If you use your own build script, you'll need to read your compiler and linker's
-manual to figure out what flags to add.
-
-### As a Shared Library (DLL)
-
-Google Test is compact, so most users can build and link it as a static library
-for the simplicity. You can choose to use Google Test as a shared library (known
-as a DLL on Windows) if you prefer.
-
-To compile *gtest* as a shared library, add
-
-    -DGTEST_CREATE_SHARED_LIBRARY=1
-
-to the compiler flags. You'll also need to tell the linker to produce a shared
-library instead - consult your linker's manual for how to do it.
-
-To compile your *tests* that use the gtest shared library, add
-
-    -DGTEST_LINKED_AS_SHARED_LIBRARY=1
-
-to the compiler flags.
-
-Note: while the above steps aren't technically necessary today when using some
-compilers (e.g. GCC), they may become necessary in the future, if we decide to
-improve the speed of loading the library (see
-<http://gcc.gnu.org/wiki/Visibility> for details). Therefore you are recommended
-to always add the above flags when using Google Test as a shared library.
-Otherwise a future release of Google Test may break your build script.
-
-### Avoiding Macro Name Clashes
-
-In C++, macros don't obey namespaces. Therefore two libraries that both define a
-macro of the same name will clash if you `#include` both definitions. In case a
-Google Test macro clashes with another library, you can force Google Test to
-rename its macro to avoid the conflict.
-
-Specifically, if both Google Test and some other code define macro FOO, you can
-add
-
-    -DGTEST_DONT_DEFINE_FOO=1
-
-to the compiler flags to tell Google Test to change the macro's name from `FOO`
-to `GTEST_FOO`. Currently `FOO` can be `FAIL`, `SUCCEED`, or `TEST`. For
-example, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll need to write
-
-    GTEST_TEST(SomeTest, DoesThis) { ... }
-
-instead of
-
-    TEST(SomeTest, DoesThis) { ... }
-
-in order to define a test.

-
-## Introduction
-
-Now that you have read the [googletest Primer](primer.md) and learned how to
-write tests using googletest, it's time to learn some new tricks. This document
-will show you more assertions as well as how to construct complex failure
-messages, propagate fatal failures, reuse and speed up your test fixtures, and
-use various flags with your tests.
-
-## More Assertions
-
-This section covers some less frequently used, but still significant,
-assertions.
-
-### Explicit Success and Failure
-
-These three assertions do not actually test a value or expression. Instead, they
-generate a success or failure directly. Like the macros that actually perform a
-test, you may stream a custom failure message into them.
-
-```c++
-SUCCEED();
-```
-
-Generates a success. This does **NOT** make the overall test succeed. A test is
-considered successful only if none of its assertions fail during its execution.
-
-NOTE: `SUCCEED()` is purely documentary and currently doesn't generate any
-user-visible output. However, we may add `SUCCEED()` messages to googletest's
-output in the future.
-
-```c++
-FAIL();
-ADD_FAILURE();
-ADD_FAILURE_AT("file_path", line_number);
-```
-
-`FAIL()` generates a fatal failure, while `ADD_FAILURE()` and `ADD_FAILURE_AT()`
-generate a nonfatal failure. These are useful when control flow, rather than a
-Boolean expression, determines the test's success or failure. For example, you
-might want to write something like:
-
-```c++
-switch(expression) {
-  case 1:
-     ... some checks ...
-  case 2:
-     ... some other checks ...
-  default:
-     FAIL() << "We shouldn't get here.";
-}
-```
-
-NOTE: you can only use `FAIL()` in functions that return `void`. See the
-[Assertion Placement section](#assertion-placement) for more information.
-
-### Exception Assertions
-
-These are for verifying that a piece of code throws (or does not throw) an
-exception of the given type:
-
-Fatal assertion                            | Nonfatal assertion                         | Verifies
------------------------------------------- | ------------------------------------------ | --------
-`ASSERT_THROW(statement, exception_type);` | `EXPECT_THROW(statement, exception_type);` | `statement` throws an exception of the given type
-`ASSERT_ANY_THROW(statement);`             | `EXPECT_ANY_THROW(statement);`             | `statement` throws an exception of any type
-`ASSERT_NO_THROW(statement);`              | `EXPECT_NO_THROW(statement);`              | `statement` doesn't throw any exception
-
-Examples:
-
-```c++
-ASSERT_THROW(Foo(5), bar_exception);
-
-EXPECT_NO_THROW({
-  int n = 5;
-  Bar(&n);
-});
-```
-
-**Availability**: requires exceptions to be enabled in the build environment
-
-### Predicate Assertions for Better Error Messages
-
-Even though googletest has a rich set of assertions, they can never be complete,
-as it's impossible (nor a good idea) to anticipate all scenarios a user might
-run into. Therefore, sometimes a user has to use `EXPECT_TRUE()` to check a
-complex expression, for lack of a better macro. This has the problem of not
-showing you the values of the parts of the expression, making it hard to
-understand what went wrong. As a workaround, some users choose to construct the
-failure message by themselves, streaming it into `EXPECT_TRUE()`. However, this
-is awkward especially when the expression has side-effects or is expensive to
-evaluate.
-
-googletest gives you three different options to solve this problem:
-
-#### Using an Existing Boolean Function
-
-If you already have a function or functor that returns `bool` (or a type that
-can be implicitly converted to `bool`), you can use it in a *predicate
-assertion* to get the function arguments printed for free:
-
-<!-- mdformat off(github rendering does not support multiline tables) -->
-
-| Fatal assertion                   | Nonfatal assertion                | Verifies                    |
-| --------------------------------- | --------------------------------- | --------------------------- |
-| `ASSERT_PRED1(pred1, val1)`       | `EXPECT_PRED1(pred1, val1)`       | `pred1(val1)` is true       |
-| `ASSERT_PRED2(pred2, val1, val2)` | `EXPECT_PRED2(pred2, val1, val2)` | `pred1(val1, val2)` is true |
-| `...`                             | `...`                             | `...`                       |
-
-<!-- mdformat on-->
-In the above, `predn` is an `n`-ary predicate function or functor, where `val1`,
-`val2`, ..., and `valn` are its arguments. The assertion succeeds if the
-predicate returns `true` when applied to the given arguments, and fails
-otherwise. When the assertion fails, it prints the value of each argument. In
-either case, the arguments are evaluated exactly once.
-
-Here's an example. Given
-
-```c++
-// Returns true if m and n have no common divisors except 1.
-bool MutuallyPrime(int m, int n) { ... }
-
-const int a = 3;
-const int b = 4;
-const int c = 10;
-```
-
-the assertion
-
-```c++
-  EXPECT_PRED2(MutuallyPrime, a, b);
-```
-
-will succeed, while the assertion
-
-```c++
-  EXPECT_PRED2(MutuallyPrime, b, c);
-```
-
-will fail with the message
-
-```none
-MutuallyPrime(b, c) is false, where
-b is 4
-c is 10
-```
-
-> NOTE:
->
-> 1.  If you see a compiler error "no matching function to call" when using
->     `ASSERT_PRED*` or `EXPECT_PRED*`, please see
->     [this](faq.md#the-compiler-complains-no-matching-function-to-call-when-i-use-assert-pred-how-do-i-fix-it)
->     for how to resolve it.
-
-#### Using a Function That Returns an AssertionResult
-
-While `EXPECT_PRED*()` and friends are handy for a quick job, the syntax is not
-satisfactory: you have to use different macros for different arities, and it
-feels more like Lisp than C++. The `::testing::AssertionResult` class solves
-this problem.
-
-An `AssertionResult` object represents the result of an assertion (whether it's
-a success or a failure, and an associated message). You can create an
-`AssertionResult` using one of these factory functions:
-
-```c++
-namespace testing {
-
-// Returns an AssertionResult object to indicate that an assertion has
-// succeeded.
-AssertionResult AssertionSuccess();
-
-// Returns an AssertionResult object to indicate that an assertion has
-// failed.
-AssertionResult AssertionFailure();
-
-}
-```
-
-You can then use the `<<` operator to stream messages to the `AssertionResult`
-object.
-
-To provide more readable messages in Boolean assertions (e.g. `EXPECT_TRUE()`),
-write a predicate function that returns `AssertionResult` instead of `bool`. For
-example, if you define `IsEven()` as:
-
-```c++
-::testing::AssertionResult IsEven(int n) {
-  if ((n % 2) == 0)
-     return ::testing::AssertionSuccess();
-  else
-     return ::testing::AssertionFailure() << n << " is odd";
-}
-```
-
-instead of:
-
-```c++
-bool IsEven(int n) {
-  return (n % 2) == 0;
-}
-```
-
-the failed assertion `EXPECT_TRUE(IsEven(Fib(4)))` will print:
-
-```none
-Value of: IsEven(Fib(4))
-  Actual: false (3 is odd)
-Expected: true
-```
-
-instead of a more opaque
-
-```none
-Value of: IsEven(Fib(4))
-  Actual: false
-Expected: true
-```
-
-If you want informative messages in `EXPECT_FALSE` and `ASSERT_FALSE` as well
-(one third of Boolean assertions in the Google code base are negative ones), and
-are fine with making the predicate slower in the success case, you can supply a
-success message:
-
-```c++
-::testing::AssertionResult IsEven(int n) {
-  if ((n % 2) == 0)
-     return ::testing::AssertionSuccess() << n << " is even";
-  else
-     return ::testing::AssertionFailure() << n << " is odd";
-}
-```
-
-Then the statement `EXPECT_FALSE(IsEven(Fib(6)))` will print
-
-```none
-  Value of: IsEven(Fib(6))
-     Actual: true (8 is even)
-  Expected: false
-```
-
-#### Using a Predicate-Formatter
-
-If you find the default message generated by `(ASSERT|EXPECT)_PRED*` and
-`(ASSERT|EXPECT)_(TRUE|FALSE)` unsatisfactory, or some arguments to your
-predicate do not support streaming to `ostream`, you can instead use the
-following *predicate-formatter assertions* to *fully* customize how the message
-is formatted:
-
-Fatal assertion                                  | Nonfatal assertion                               | Verifies
------------------------------------------------- | ------------------------------------------------ | --------
-`ASSERT_PRED_FORMAT1(pred_format1, val1);`       | `EXPECT_PRED_FORMAT1(pred_format1, val1);`       | `pred_format1(val1)` is successful
-`ASSERT_PRED_FORMAT2(pred_format2, val1, val2);` | `EXPECT_PRED_FORMAT2(pred_format2, val1, val2);` | `pred_format2(val1, val2)` is successful
-`...`                                            | `...`                                            | ...
-
-The difference between this and the previous group of macros is that instead of
-a predicate, `(ASSERT|EXPECT)_PRED_FORMAT*` take a *predicate-formatter*
-(`pred_formatn`), which is a function or functor with the signature:
-
-```c++
-::testing::AssertionResult PredicateFormattern(const char* expr1,
-                                               const char* expr2,
-                                               ...
-                                               const char* exprn,
-                                               T1 val1,
-                                               T2 val2,
-                                               ...
-                                               Tn valn);
-```
-
-where `val1`, `val2`, ..., and `valn` are the values of the predicate arguments,
-and `expr1`, `expr2`, ..., and `exprn` are the corresponding expressions as they
-appear in the source code. The types `T1`, `T2`, ..., and `Tn` can be either
-value types or reference types. For example, if an argument has type `Foo`, you
-can declare it as either `Foo` or `const Foo&`, whichever is appropriate.
-
-As an example, let's improve the failure message in `MutuallyPrime()`, which was
-used with `EXPECT_PRED2()`:
-
-```c++
-// Returns the smallest prime common divisor of m and n,
-// or 1 when m and n are mutually prime.
-int SmallestPrimeCommonDivisor(int m, int n) { ... }
-
-// A predicate-formatter for asserting that two integers are mutually prime.
-::testing::AssertionResult AssertMutuallyPrime(const char* m_expr,
-                                               const char* n_expr,
-                                               int m,
-                                               int n) {
-  if (MutuallyPrime(m, n)) return ::testing::AssertionSuccess();
-
-  return ::testing::AssertionFailure() << m_expr << " and " << n_expr
-      << " (" << m << " and " << n << ") are not mutually prime, "
-      << "as they have a common divisor " << SmallestPrimeCommonDivisor(m, n);
-}
-```
-
-With this predicate-formatter, we can use
-
-```c++
-  EXPECT_PRED_FORMAT2(AssertMutuallyPrime, b, c);
-```
-
-to generate the message
-
-```none
-b and c (4 and 10) are not mutually prime, as they have a common divisor 2.
-```
-
-As you may have realized, many of the built-in assertions we introduced earlier
-are special cases of `(EXPECT|ASSERT)_PRED_FORMAT*`. In fact, most of them are
-indeed defined using `(EXPECT|ASSERT)_PRED_FORMAT*`.
-
-### Floating-Point Comparison
-
-Comparing floating-point numbers is tricky. Due to round-off errors, it is very
-unlikely that two floating-points will match exactly. Therefore, `ASSERT_EQ` 's
-naive comparison usually doesn't work. And since floating-points can have a wide
-value range, no single fixed error bound works. It's better to compare by a
-fixed relative error bound, except for values close to 0 due to the loss of
-precision there.
-
-In general, for floating-point comparison to make sense, the user needs to
-carefully choose the error bound. If they don't want or care to, comparing in
-terms of Units in the Last Place (ULPs) is a good default, and googletest
-provides assertions to do this. Full details about ULPs are quite long; if you
-want to learn more, see
-[here](https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/).

-#### Floating-Point Macros
-
-<!-- mdformat off(github rendering does not support multiline tables) -->
-
-| Fatal assertion                 | Nonfatal assertion              | Verifies                                 |
-| ------------------------------- | ------------------------------- | ---------------------------------------- |
-| `ASSERT_FLOAT_EQ(val1, val2);`  | `EXPECT_FLOAT_EQ(val1, val2);`  | the two `float` values are almost equal  |
-| `ASSERT_DOUBLE_EQ(val1, val2);` | `EXPECT_DOUBLE_EQ(val1, val2);` | the two `double` values are almost equal |
-
-<!-- mdformat on-->
-
-By "almost equal" we mean the values are within 4 ULP's from each other.
-
-The following assertions allow you to choose the acceptable error bound:
-
-<!-- mdformat off(github rendering does not support multiline tables) -->
-
-| Fatal assertion                       | Nonfatal assertion                    | Verifies                                                                         |
-| ------------------------------------- | ------------------------------------- | -------------------------------------------------------------------------------- |
-| `ASSERT_NEAR(val1, val2, abs_error);` | `EXPECT_NEAR(val1, val2, abs_error);` | the difference between `val1` and `val2` doesn't exceed the given absolute error |
-
-<!-- mdformat on-->
-
-#### Floating-Point Predicate-Format Functions
-
-Some floating-point operations are useful, but not that often used. In order to
-avoid an explosion of new macros, we provide them as predicate-format functions
-that can be used in predicate assertion macros (e.g. `EXPECT_PRED_FORMAT2`,
-etc).
-
-```c++
-EXPECT_PRED_FORMAT2(::testing::FloatLE, val1, val2);
-EXPECT_PRED_FORMAT2(::testing::DoubleLE, val1, val2);
-```
-
-Verifies that `val1` is less than, or almost equal to, `val2`. You can replace
-`EXPECT_PRED_FORMAT2` in the above table with `ASSERT_PRED_FORMAT2`.
-
-### Asserting Using gMock Matchers
-
-[gMock](../../googlemock) comes with a library of matchers for validating
-arguments passed to mock objects. A gMock *matcher* is basically a predicate
-that knows how to describe itself. It can be used in these assertion macros:
-
-<!-- mdformat off(github rendering does not support multiline tables) -->
-
-| Fatal assertion                | Nonfatal assertion             | Verifies              |
-| ------------------------------ | ------------------------------ | --------------------- |
-| `ASSERT_THAT(value, matcher);` | `EXPECT_THAT(value, matcher);` | value matches matcher |
-
-<!-- mdformat on-->
-
-For example, `StartsWith(prefix)` is a matcher that matches a string starting
-with `prefix`, and you can write:
-
-```c++
-using ::testing::StartsWith;
-...
-    // Verifies that Foo() returns a string starting with "Hello".
-    EXPECT_THAT(Foo(), StartsWith("Hello"));
-```
-
-Read this
-[recipe](../../googlemock/docs/cook_book.md#using-matchers-in-googletest-assertions)
-in the gMock Cookbook for more details.
-
-gMock has a rich set of matchers. You can do many things googletest cannot do
-alone with them. For a list of matchers gMock provides, read
-[this](../../googlemock/docs/cook_book.md##using-matchers). It's easy to write
-your [own matchers](../../googlemock/docs/cook_book.md#NewMatchers) too.
-
-gMock is bundled with googletest, so you don't need to add any build dependency
-in order to take advantage of this. Just include `"testing/base/public/gmock.h"`
-and you're ready to go.
-
-### More String Assertions
-
-(Please read the [previous](#asserting-using-gmock-matchers) section first if
-you haven't.)
-
-You can use the gMock
-[string matchers](../../googlemock/docs/cheat_sheet.md#string-matchers) with
-`EXPECT_THAT()` or `ASSERT_THAT()` to do more string comparison tricks
-(sub-string, prefix, suffix, regular expression, and etc). For example,
-
-```c++
-using ::testing::HasSubstr;
-using ::testing::MatchesRegex;
-...
-  ASSERT_THAT(foo_string, HasSubstr("needle"));
-  EXPECT_THAT(bar_string, MatchesRegex("\\w*\\d+"));
-```
-
-If the string contains a well-formed HTML or XML document, you can check whether
-its DOM tree matches an
-[XPath expression](http://www.w3.org/TR/xpath/#contents):
-
-```c++
-// Currently still in //template/prototemplate/testing:xpath_matcher
-#include "template/prototemplate/testing/xpath_matcher.h"
-using prototemplate::testing::MatchesXPath;
-EXPECT_THAT(html_string, MatchesXPath("//a[text()='click here']"));
-```
-
-### Windows HRESULT assertions
-
-These assertions test for `HRESULT` success or failure.
-
-Fatal assertion                        | Nonfatal assertion                     | Verifies
--------------------------------------- | -------------------------------------- | --------
-`ASSERT_HRESULT_SUCCEEDED(expression)` | `EXPECT_HRESULT_SUCCEEDED(expression)` | `expression` is a success `HRESULT`
-`ASSERT_HRESULT_FAILED(expression)`    | `EXPECT_HRESULT_FAILED(expression)`    | `expression` is a failure `HRESULT`
-
-The generated output contains the human-readable error message associated with
-the `HRESULT` code returned by `expression`.
-
-You might use them like this:
-
-```c++
-CComPtr<IShellDispatch2> shell;
-ASSERT_HRESULT_SUCCEEDED(shell.CoCreateInstance(L"Shell.Application"));
-CComVariant empty;
-ASSERT_HRESULT_SUCCEEDED(shell->ShellExecute(CComBSTR(url), empty, empty, empty, empty));
-```
-
-### Type Assertions
-
-You can call the function
-
-```c++
-::testing::StaticAssertTypeEq<T1, T2>();
-```
-
-to assert that types `T1` and `T2` are the same. The function does nothing if
-the assertion is satisfied. If the types are different, the function call will
-fail to compile, the compiler error message will say that
-`type1 and type2 are not the same type` and most likely (depending on the compiler)
-show you the actual values of `T1` and `T2`. This is mainly useful inside
-template code.
-
-**Caveat**: When used inside a member function of a class template or a function
-template, `StaticAssertTypeEq<T1, T2>()` is effective only if the function is
-instantiated. For example, given:
-
-```c++
-template <typename T> class Foo {
- public:
-  void Bar() { ::testing::StaticAssertTypeEq<int, T>(); }
-};
-```
-
-the code:
-
-```c++
-void Test1() { Foo<bool> foo; }
-```
-
-will not generate a compiler error, as `Foo<bool>::Bar()` is never actually
-instantiated. Instead, you need:
-
-```c++
-void Test2() { Foo<bool> foo; foo.Bar(); }
-```
-
-to cause a compiler error.
-
-### Assertion Placement
-
-You can use assertions in any C++ function. In particular, it doesn't have to be
-a method of the test fixture class. The one constraint is that assertions that
-generate a fatal failure (`FAIL*` and `ASSERT_*`) can only be used in
-void-returning functions. This is a consequence of Google's not using
-exceptions. By placing it in a non-void function you'll get a confusing compile
-error like `"error: void value not ignored as it ought to be"` or `"cannot
-initialize return object of type 'bool' with an rvalue of type 'void'"` or
-`"error: no viable conversion from 'void' to 'string'"`.
-
-If you need to use fatal assertions in a function that returns non-void, one
-option is to make the function return the value in an out parameter instead. For
-example, you can rewrite `T2 Foo(T1 x)` to `void Foo(T1 x, T2* result)`. You
-need to make sure that `*result` contains some sensible value even when the
-function returns prematurely. As the function now returns `void`, you can use
-any assertion inside of it.
-
-If changing the function's type is not an option, you should just use assertions
-that generate non-fatal failures, such as `ADD_FAILURE*` and `EXPECT_*`.
-
-NOTE: Constructors and destructors are not considered void-returning functions,
-according to the C++ language specification, and so you may not use fatal
-assertions in them; you'll get a compilation error if you try. Instead, either
-call `abort` and crash the entire test executable, or put the fatal assertion in
-a `SetUp`/`TearDown` function; see
-[constructor/destructor vs. `SetUp`/`TearDown`](faq.md#CtorVsSetUp)
-
-WARNING: A fatal assertion in a helper function (private void-returning method)
-called from a constructor or destructor does not does not terminate the current
-test, as your intuition might suggest: it merely returns from the constructor or
-destructor early, possibly leaving your object in a partially-constructed or
-partially-destructed state! You almost certainly want to `abort` or use
-`SetUp`/`TearDown` instead.
-
-## Teaching googletest How to Print Your Values
-
-When a test assertion such as `EXPECT_EQ` fails, googletest prints the argument
-values to help you debug. It does this using a user-extensible value printer.
-
-This printer knows how to print built-in C++ types, native arrays, STL
-containers, and any type that supports the `<<` operator. For other types, it
-prints the raw bytes in the value and hopes that you the user can figure it out.
-
-As mentioned earlier, the printer is *extensible*. That means you can teach it
-to do a better job at printing your particular type than to dump the bytes. To
-do that, define `<<` for your type:
-
-```c++
-#include <ostream>
-
-namespace foo {
-
-class Bar {  // We want googletest to be able to print instances of this.
-...
-  // Create a free inline friend function.
-  friend std::ostream& operator<<(std::ostream& os, const Bar& bar) {
-    return os << bar.DebugString();  // whatever needed to print bar to os
-  }
-};
-
-// If you can't declare the function in the class it's important that the
-// << operator is defined in the SAME namespace that defines Bar.  C++'s look-up
-// rules rely on that.
-std::ostream& operator<<(std::ostream& os, const Bar& bar) {
-  return os << bar.DebugString();  // whatever needed to print bar to os
-}
-
-}  // namespace foo
-```
-
-Sometimes, this might not be an option: your team may consider it bad style to
-have a `<<` operator for `Bar`, or `Bar` may already have a `<<` operator that
-doesn't do what you want (and you cannot change it). If so, you can instead
-define a `PrintTo()` function like this:
-
-```c++
-#include <ostream>
-
-namespace foo {
-
-class Bar {
-  ...
-  friend void PrintTo(const Bar& bar, std::ostream* os) {
-    *os << bar.DebugString();  // whatever needed to print bar to os
-  }
-};
-
-// If you can't declare the function in the class it's important that PrintTo()
-// is defined in the SAME namespace that defines Bar.  C++'s look-up rules rely
-// on that.
-void PrintTo(const Bar& bar, std::ostream* os) {
-  *os << bar.DebugString();  // whatever needed to print bar to os
-}
-
-}  // namespace foo
-```
-
-If you have defined both `<<` and `PrintTo()`, the latter will be used when
-googletest is concerned. This allows you to customize how the value appears in
-googletest's output without affecting code that relies on the behavior of its
-`<<` operator.
-
-If you want to print a value `x` using googletest's value printer yourself, just
-call `::testing::PrintToString(x)`, which returns an `std::string`:
-
-```c++
-vector<pair<Bar, int> > bar_ints = GetBarIntVector();
-
-EXPECT_TRUE(IsCorrectBarIntVector(bar_ints))
-    << "bar_ints = " << ::testing::PrintToString(bar_ints);
-```
-
-## Death Tests
-
-In many applications, there are assertions that can cause application failure if
-a condition is not met. These sanity checks, which ensure that the program is in
-a known good state, are there to fail at the earliest possible time after some
-program state is corrupted. If the assertion checks the wrong condition, then
-the program may proceed in an erroneous state, which could lead to memory
-corruption, security holes, or worse. Hence it is vitally important to test that
-such assertion statements work as expected.
-
-Since these precondition checks cause the processes to die, we call such tests
-_death tests_. More generally, any test that checks that a program terminates
-(except by throwing an exception) in an expected fashion is also a death test.
-
-Note that if a piece of code throws an exception, we don't consider it "death"
-for the purpose of death tests, as the caller of the code could catch the
-exception and avoid the crash. If you want to verify exceptions thrown by your
-code, see [Exception Assertions](#ExceptionAssertions).
-
-If you want to test `EXPECT_*()/ASSERT_*()` failures in your test code, see
-Catching Failures
-
-### How to Write a Death Test
-
-googletest has the following macros to support death tests:
-
-Fatal assertion                                  | Nonfatal assertion                               | Verifies
------------------------------------------------- | ------------------------------------------------ | --------
-`ASSERT_DEATH(statement, matcher);`              | `EXPECT_DEATH(statement, matcher);`              | `statement` crashes with the given error
-`ASSERT_DEATH_IF_SUPPORTED(statement, matcher);` | `EXPECT_DEATH_IF_SUPPORTED(statement, matcher);` | if death tests are supported, verifies that `statement` crashes with the given error; otherwise verifies nothing
-`ASSERT_EXIT(statement, predicate, matcher);`    | `EXPECT_EXIT(statement, predicate, matcher);`    | `statement` exits with the given error, and its exit code matches `predicate`
-
-where `statement` is a statement that is expected to cause the process to die,
-`predicate` is a function or function object that evaluates an integer exit
-status, and `matcher` is either a GMock matcher matching a `const std::string&`
-or a (Perl) regular expression - either of which is matched against the stderr
-output of `statement`. For legacy reasons, a bare string (i.e. with no matcher)
-is interpreted as `ContainsRegex(str)`, **not** `Eq(str)`. Note that `statement`
-can be *any valid statement* (including *compound statement*) and doesn't have
-to be an expression.
-
-As usual, the `ASSERT` variants abort the current test function, while the
-`EXPECT` variants do not.
-
-> NOTE: We use the word "crash" here to mean that the process terminates with a
-> *non-zero* exit status code. There are two possibilities: either the process
-> has called `exit()` or `_exit()` with a non-zero value, or it may be killed by
-> a signal.
->
-> This means that if `*statement*` terminates the process with a 0 exit code, it
-> is *not* considered a crash by `EXPECT_DEATH`. Use `EXPECT_EXIT` instead if
-> this is the case, or if you want to restrict the exit code more precisely.
-
-A predicate here must accept an `int` and return a `bool`. The death test
-succeeds only if the predicate returns `true`. googletest defines a few
-predicates that handle the most common cases:
-
-```c++
-::testing::ExitedWithCode(exit_code)
-```
-
-This expression is `true` if the program exited normally with the given exit
-code.
-
-```c++
-::testing::KilledBySignal(signal_number)  // Not available on Windows.
-```
-
-This expression is `true` if the program was killed by the given signal.
-
-The `*_DEATH` macros are convenient wrappers for `*_EXIT` that use a predicate
-that verifies the process' exit code is non-zero.
-
-Note that a death test only cares about three things:
-
-1.  does `statement` abort or exit the process?
-2.  (in the case of `ASSERT_EXIT` and `EXPECT_EXIT`) does the exit status
-    satisfy `predicate`? Or (in the case of `ASSERT_DEATH` and `EXPECT_DEATH`)
-    is the exit status non-zero? And
-3.  does the stderr output match `regex`?
-
-In particular, if `statement` generates an `ASSERT_*` or `EXPECT_*` failure, it
-will **not** cause the death test to fail, as googletest assertions don't abort
-the process.
-
-To write a death test, simply use one of the above macros inside your test
-function. For example,
-
-```c++
-TEST(MyDeathTest, Foo) {
-  // This death test uses a compound statement.
-  ASSERT_DEATH({
-    int n = 5;
-    Foo(&n);
-  }, "Error on line .* of Foo()");
-}
-
-TEST(MyDeathTest, NormalExit) {
-  EXPECT_EXIT(NormalExit(), ::testing::ExitedWithCode(0), "Success");
-}
-
-TEST(MyDeathTest, KillMyself) {
-  EXPECT_EXIT(KillMyself(), ::testing::KilledBySignal(SIGKILL),
-              "Sending myself unblockable signal");
-}
-```
-
-verifies that:
-
-*   calling `Foo(5)` causes the process to die with the given error message,
-*   calling `NormalExit()` causes the process to print `"Success"` to stderr and
-    exit with exit code 0, and
-*   calling `KillMyself()` kills the process with signal `SIGKILL`.
-
-The test function body may contain other assertions and statements as well, if
-necessary.
-
-### Death Test Naming
-
-IMPORTANT: We strongly recommend you to follow the convention of naming your
-**test suite** (not test) `*DeathTest` when it contains a death test, as
-demonstrated in the above example. The
-[Death Tests And Threads](#death-tests-and-threads) section below explains why.
-
-If a test fixture class is shared by normal tests and death tests, you can use
-`using` or `typedef` to introduce an alias for the fixture class and avoid
-duplicating its code:
-
-```c++
-class FooTest : public ::testing::Test { ... };
-
-using FooDeathTest = FooTest;
-
-TEST_F(FooTest, DoesThis) {
-  // normal test
-}
-
-TEST_F(FooDeathTest, DoesThat) {
-  // death test
-}
-```
-
-### Regular Expression Syntax
-
-On POSIX systems (e.g. Linux, Cygwin, and Mac), googletest uses the
-[POSIX extended regular expression](http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap09.html#tag_09_04)
-syntax. To learn about this syntax, you may want to read this
-[Wikipedia entry](http://en.wikipedia.org/wiki/Regular_expression#POSIX_Extended_Regular_Expressions).
-
-On Windows, googletest uses its own simple regular expression implementation. It
-lacks many features. For example, we don't support union (`"x|y"`), grouping
-(`"(xy)"`), brackets (`"[xy]"`), and repetition count (`"x{5,7}"`), among
-others. Below is what we do support (`A` denotes a literal character, period
-(`.`), or a single `\\ ` escape sequence; `x` and `y` denote regular
-expressions.):
-
-Expression | Meaning
----------- | --------------------------------------------------------------
-`c`        | matches any literal character `c`
-`\\d`      | matches any decimal digit
-`\\D`      | matches any character that's not a decimal digit
-`\\f`      | matches `\f`
-`\\n`      | matches `\n`
-`\\r`      | matches `\r`
-`\\s`      | matches any ASCII whitespace, including `\n`
-`\\S`      | matches any character that's not a whitespace
-`\\t`      | matches `\t`
-`\\v`      | matches `\v`
-`\\w`      | matches any letter, `_`, or decimal digit
-`\\W`      | matches any character that `\\w` doesn't match
-`\\c`      | matches any literal character `c`, which must be a punctuation
-`.`        | matches any single character except `\n`
-`A?`       | matches 0 or 1 occurrences of `A`
-`A*`       | matches 0 or many occurrences of `A`
-`A+`       | matches 1 or many occurrences of `A`
-`^`        | matches the beginning of a string (not that of each line)
-`$`        | matches the end of a string (not that of each line)
-`xy`       | matches `x` followed by `y`
-
-To help you determine which capability is available on your system, googletest
-defines macros to govern which regular expression it is using. The macros are:
-`GTEST_USES_SIMPLE_RE=1` or `GTEST_USES_POSIX_RE=1`. If you want your death
-tests to work in all cases, you can either `#if` on these macros or use the more
-limited syntax only.
-
-### How It Works
-
-Under the hood, `ASSERT_EXIT()` spawns a new process and executes the death test
-statement in that process. The details of how precisely that happens depend on
-the platform and the variable ::testing::GTEST_FLAG(death_test_style) (which is
-initialized from the command-line flag `--gtest_death_test_style`).
-
-*   On POSIX systems, `fork()` (or `clone()` on Linux) is used to spawn the
-    child, after which:
-    *   If the variable's value is `"fast"`, the death test statement is
-        immediately executed.
-    *   If the variable's value is `"threadsafe"`, the child process re-executes
-        the unit test binary just as it was originally invoked, but with some
-        extra flags to cause just the single death test under consideration to
-        be run.
-*   On Windows, the child is spawned using the `CreateProcess()` API, and
-    re-executes the binary to cause just the single death test under
-    consideration to be run - much like the `threadsafe` mode on POSIX.
-
-Other values for the variable are illegal and will cause the death test to fail.
-Currently, the flag's default value is **"fast"**
-
-1.  the child's exit status satisfies the predicate, and
-2.  the child's stderr matches the regular expression.
-
-If the death test statement runs to completion without dying, the child process
-will nonetheless terminate, and the assertion fails.
-
-### Death Tests And Threads
-
-The reason for the two death test styles has to do with thread safety. Due to
-well-known problems with forking in the presence of threads, death tests should
-be run in a single-threaded context. Sometimes, however, it isn't feasible to
-arrange that kind of environment. For example, statically-initialized modules
-may start threads before main is ever reached. Once threads have been created,
-it may be difficult or impossible to clean them up.
-
-googletest has three features intended to raise awareness of threading issues.
-
-1.  A warning is emitted if multiple threads are running when a death test is
-    encountered.
-2.  Test suites with a name ending in "DeathTest" are run before all other
-    tests.
-3.  It uses `clone()` instead of `fork()` to spawn the child process on Linux
-    (`clone()` is not available on Cygwin and Mac), as `fork()` is more likely
-    to cause the child to hang when the parent process has multiple threads.
-
-It's perfectly fine to create threads inside a death test statement; they are
-executed in a separate process and cannot affect the parent.
-
-### Death Test Styles
-
-The "threadsafe" death test style was introduced in order to help mitigate the
-risks of testing in a possibly multithreaded environment. It trades increased
-test execution time (potentially dramatically so) for improved thread safety.
-
-The automated testing framework does not set the style flag. You can choose a
-particular style of death tests by setting the flag programmatically:
-
-```c++
-testing::FLAGS_gtest_death_test_style="threadsafe"
-```
-
-You can do this in `main()` to set the style for all death tests in the binary,
-or in individual tests. Recall that flags are saved before running each test and
-restored afterwards, so you need not do that yourself. For example:
-
-```c++
-int main(int argc, char** argv) {
-  InitGoogle(argv[0], &argc, &argv, true);
-  ::testing::FLAGS_gtest_death_test_style = "fast";
-  return RUN_ALL_TESTS();
-}
-
-TEST(MyDeathTest, TestOne) {
-  ::testing::FLAGS_gtest_death_test_style = "threadsafe";
-  // This test is run in the "threadsafe" style:
-  ASSERT_DEATH(ThisShouldDie(), "");
-}
-
-TEST(MyDeathTest, TestTwo) {
-  // This test is run in the "fast" style:
-  ASSERT_DEATH(ThisShouldDie(), "");
-}
-```
-
-### Caveats
-
-The `statement` argument of `ASSERT_EXIT()` can be any valid C++ statement. If
-it leaves the current function via a `return` statement or by throwing an
-exception, the death test is considered to have failed. Some googletest macros
-may return from the current function (e.g. `ASSERT_TRUE()`), so be sure to avoid
-them in `statement`.
-
-Since `statement` runs in the child process, any in-memory side effect (e.g.
-modifying a variable, releasing memory, etc) it causes will *not* be observable
-in the parent process. In particular, if you release memory in a death test,
-your program will fail the heap check as the parent process will never see the
-memory reclaimed. To solve this problem, you can
-
-1.  try not to free memory in a death test;
-2.  free the memory again in the parent process; or
-3.  do not use the heap checker in your program.
-
-Due to an implementation detail, you cannot place multiple death test assertions
-on the same line; otherwise, compilation will fail with an unobvious error
-message.
-
-Despite the improved thread safety afforded by the "threadsafe" style of death
-test, thread problems such as deadlock are still possible in the presence of
-handlers registered with `pthread_atfork(3)`.
-
-
-## Using Assertions in Sub-routines
-
-### Adding Traces to Assertions
-
-If a test sub-routine is called from several places, when an assertion inside it
-fails, it can be hard to tell which invocation of the sub-routine the failure is
-from. You can alleviate this problem using extra logging or custom failure
-messages, but that usually clutters up your tests. A better solution is to use
-the `SCOPED_TRACE` macro or the `ScopedTrace` utility:
-
-```c++
-SCOPED_TRACE(message);
-ScopedTrace trace("file_path", line_number, message);
-```
-
-where `message` can be anything streamable to `std::ostream`. `SCOPED_TRACE`
-macro will cause the current file name, line number, and the given message to be
-added in every failure message. `ScopedTrace` accepts explicit file name and
-line number in arguments, which is useful for writing test helpers. The effect
-will be undone when the control leaves the current lexical scope.
-
-For example,
-
-```c++
-10: void Sub1(int n) {
-11:   EXPECT_EQ(Bar(n), 1);
-12:   EXPECT_EQ(Bar(n + 1), 2);
-13: }
-14:
-15: TEST(FooTest, Bar) {
-16:   {
-17:     SCOPED_TRACE("A");  // This trace point will be included in
-18:                         // every failure in this scope.
-19:     Sub1(1);
-20:   }
-21:   // Now it won't.
-22:   Sub1(9);
-23: }
-```
-
-could result in messages like these:
-
-```none
-path/to/foo_test.cc:11: Failure
-Value of: Bar(n)
-Expected: 1
-  Actual: 2
-   Trace:
-path/to/foo_test.cc:17: A
-
-path/to/foo_test.cc:12: Failure
-Value of: Bar(n + 1)
-Expected: 2
-  Actual: 3
-```
-
-Without the trace, it would've been difficult to know which invocation of
-`Sub1()` the two failures come from respectively. (You could add an extra
-message to each assertion in `Sub1()` to indicate the value of `n`, but that's
-tedious.)
-
-Some tips on using `SCOPED_TRACE`:
-
-1.  With a suitable message, it's often enough to use `SCOPED_TRACE` at the
-    beginning of a sub-routine, instead of at each call site.
-2.  When calling sub-routines inside a loop, make the loop iterator part of the
-    message in `SCOPED_TRACE` such that you can know which iteration the failure
-    is from.
-3.  Sometimes the line number of the trace point is enough for identifying the
-    particular invocation of a sub-routine. In this case, you don't have to
-    choose a unique message for `SCOPED_TRACE`. You can simply use `""`.
-4.  You can use `SCOPED_TRACE` in an inner scope when there is one in the outer
-    scope. In this case, all active trace points will be included in the failure
-    messages, in reverse order they are encountered.
-5.  The trace dump is clickable in Emacs - hit `return` on a line number and
-    you'll be taken to that line in the source file!
-
-### Propagating Fatal Failures
-
-A common pitfall when using `ASSERT_*` and `FAIL*` is not understanding that
-when they fail they only abort the _current function_, not the entire test. For
-example, the following test will segfault:
-
-```c++
-void Subroutine() {
-  // Generates a fatal failure and aborts the current function.
-  ASSERT_EQ(1, 2);
-
-  // The following won't be executed.
-  ...
-}
-
-TEST(FooTest, Bar) {
-  Subroutine();  // The intended behavior is for the fatal failure
-                 // in Subroutine() to abort the entire test.
-
-  // The actual behavior: the function goes on after Subroutine() returns.
-  int* p = NULL;
-  *p = 3;  // Segfault!
-}
-```
-
-To alleviate this, googletest provides three different solutions. You could use
-either exceptions, the `(ASSERT|EXPECT)_NO_FATAL_FAILURE` assertions or the
-`HasFatalFailure()` function. They are described in the following two
-subsections.
-
-#### Asserting on Subroutines with an exception
-
-The following code can turn ASSERT-failure into an exception:
-
-```c++
-class ThrowListener : public testing::EmptyTestEventListener {
-  void OnTestPartResult(const testing::TestPartResult& result) override {
-    if (result.type() == testing::TestPartResult::kFatalFailure) {
-      throw testing::AssertionException(result);
-    }
-  }
-};
-int main(int argc, char** argv) {
-  ...
-  testing::UnitTest::GetInstance()->listeners().Append(new ThrowListener);
-  return RUN_ALL_TESTS();
-}
-```
-
-This listener should be added after other listeners if you have any, otherwise
-they won't see failed `OnTestPartResult`.
-
-#### Asserting on Subroutines
-
-As shown above, if your test calls a subroutine that has an `ASSERT_*` failure
-in it, the test will continue after the subroutine returns. This may not be what
-you want.
-
-Often people want fatal failures to propagate like exceptions. For that
-googletest offers the following macros:
-
-Fatal assertion                       | Nonfatal assertion                    | Verifies
-------------------------------------- | ------------------------------------- | --------
-`ASSERT_NO_FATAL_FAILURE(statement);` | `EXPECT_NO_FATAL_FAILURE(statement);` | `statement` doesn't generate any new fatal failures in the current thread.
-
-Only failures in the thread that executes the assertion are checked to determine
-the result of this type of assertions. If `statement` creates new threads,
-failures in these threads are ignored.
-
-Examples:
-
-```c++
-ASSERT_NO_FATAL_FAILURE(Foo());
-
-int i;
-EXPECT_NO_FATAL_FAILURE({
-  i = Bar();
-});
-```
-
-Assertions from multiple threads are currently not supported on Windows.
-
-#### Checking for Failures in the Current Test
-
-`HasFatalFailure()` in the `::testing::Test` class returns `true` if an
-assertion in the current test has suffered a fatal failure. This allows
-functions to catch fatal failures in a sub-routine and return early.
-
-```c++
-class Test {
- public:
-  ...
-  static bool HasFatalFailure();
-};
-```
-
-The typical usage, which basically simulates the behavior of a thrown exception,
-is:
-
-```c++
-TEST(FooTest, Bar) {
-  Subroutine();
-  // Aborts if Subroutine() had a fatal failure.
-  if (HasFatalFailure()) return;
-
-  // The following won't be executed.
-  ...
-}
-```
-
-If `HasFatalFailure()` is used outside of `TEST()` , `TEST_F()` , or a test
-fixture, you must add the `::testing::Test::` prefix, as in:
-
-```c++
-if (::testing::Test::HasFatalFailure()) return;
-```
-
-Similarly, `HasNonfatalFailure()` returns `true` if the current test has at
-least one non-fatal failure, and `HasFailure()` returns `true` if the current
-test has at least one failure of either kind.
-
-## Logging Additional Information
-
-In your test code, you can call `RecordProperty("key", value)` to log additional
-information, where `value` can be either a string or an `int`. The *last* value
-recorded for a key will be emitted to the
-[XML output](#generating-an-xml-report) if you specify one. For example, the
-test
-
-```c++
-TEST_F(WidgetUsageTest, MinAndMaxWidgets) {
-  RecordProperty("MaximumWidgets", ComputeMaxUsage());
-  RecordProperty("MinimumWidgets", ComputeMinUsage());
-}
-```
-
-will output XML like this:
-
-```xml
-  ...
-    <testcase name="MinAndMaxWidgets" status="run" time="0.006" classname="WidgetUsageTest" MaximumWidgets="12" MinimumWidgets="9" />
-  ...
-```
-
-> NOTE:
->
-> *   `RecordProperty()` is a static member of the `Test` class. Therefore it
->     needs to be prefixed with `::testing::Test::` if used outside of the
->     `TEST` body and the test fixture class.
-> *   `*key*` must be a valid XML attribute name, and cannot conflict with the
->     ones already used by googletest (`name`, `status`, `time`, `classname`,
->     `type_param`, and `value_param`).
-> *   Calling `RecordProperty()` outside of the lifespan of a test is allowed.
->     If it's called outside of a test but between a test suite's
->     `SetUpTestSuite()` and `TearDownTestSuite()` methods, it will be
->     attributed to the XML element for the test suite. If it's called outside
->     of all test suites (e.g. in a test environment), it will be attributed to
->     the top-level XML element.
-
-## Sharing Resources Between Tests in the Same Test Suite
-
-googletest creates a new test fixture object for each test in order to make
-tests independent and easier to debug. However, sometimes tests use resources
-that are expensive to set up, making the one-copy-per-test model prohibitively
-expensive.
-
-If the tests don't change the resource, there's no harm in their sharing a
-single resource copy. So, in addition to per-test set-up/tear-down, googletest
-also supports per-test-suite set-up/tear-down. To use it:
-
-1.  In your test fixture class (say `FooTest` ), declare as `static` some member
-    variables to hold the shared resources.
-2.  Outside your test fixture class (typically just below it), define those
-    member variables, optionally giving them initial values.
-3.  In the same test fixture class, define a `static void SetUpTestSuite()`
-    function (remember not to spell it as **`SetupTestSuite`** with a small
-    `u`!) to set up the shared resources and a `static void TearDownTestSuite()`
-    function to tear them down.
-
-That's it! googletest automatically calls `SetUpTestSuite()` before running the
-*first test* in the `FooTest` test suite (i.e. before creating the first
-`FooTest` object), and calls `TearDownTestSuite()` after running the *last test*
-in it (i.e. after deleting the last `FooTest` object). In between, the tests can
-use the shared resources.
-
-Remember that the test order is undefined, so your code can't depend on a test
-preceding or following another. Also, the tests must either not modify the state
-of any shared resource, or, if they do modify the state, they must restore the
-state to its original value before passing control to the next test.
-
-Here's an example of per-test-suite set-up and tear-down:
-
-```c++
-class FooTest : public ::testing::Test {
- protected:
-  // Per-test-suite set-up.
-  // Called before the first test in this test suite.
-  // Can be omitted if not needed.
-  static void SetUpTestSuite() {
-    shared_resource_ = new ...;
-  }
-
-  // Per-test-suite tear-down.
-  // Called after the last test in this test suite.
-  // Can be omitted if not needed.
-  static void TearDownTestSuite() {
-    delete shared_resource_;
-    shared_resource_ = NULL;
-  }
-
-  // You can define per-test set-up logic as usual.
-  virtual void SetUp() { ... }
-
-  // You can define per-test tear-down logic as usual.
-  virtual void TearDown() { ... }
-
-  // Some expensive resource shared by all tests.
-  static T* shared_resource_;
-};
-
-T* FooTest::shared_resource_ = NULL;
-
-TEST_F(FooTest, Test1) {
-  ... you can refer to shared_resource_ here ...
-}
-
-TEST_F(FooTest, Test2) {
-  ... you can refer to shared_resource_ here ...
-}
-```
-
-NOTE: Though the above code declares `SetUpTestSuite()` protected, it may
-sometimes be necessary to declare it public, such as when using it with
-`TEST_P`.
-
-## Global Set-Up and Tear-Down
-
-Just as you can do set-up and tear-down at the test level and the test suite
-level, you can also do it at the test program level. Here's how.
-
-First, you subclass the `::testing::Environment` class to define a test
-environment, which knows how to set-up and tear-down:
-
-```c++
-class Environment : public ::testing::Environment {
- public:
-  virtual ~Environment() {}
-
-  // Override this to define how to set up the environment.
-  void SetUp() override {}
-
-  // Override this to define how to tear down the environment.
-  void TearDown() override {}
-};
-```
-
-Then, you register an instance of your environment class with googletest by
-calling the `::testing::AddGlobalTestEnvironment()` function:
-
-```c++
-Environment* AddGlobalTestEnvironment(Environment* env);
-```
-
-Now, when `RUN_ALL_TESTS()` is called, it first calls the `SetUp()` method of
-each environment object, then runs the tests if none of the environments
-reported fatal failures and `GTEST_SKIP()` was not called. `RUN_ALL_TESTS()`
-always calls `TearDown()` with each environment object, regardless of whether or
-not the tests were run.
-
-It's OK to register multiple environment objects. In this suite, their `SetUp()`
-will be called in the order they are registered, and their `TearDown()` will be
-called in the reverse order.
-
-Note that googletest takes ownership of the registered environment objects.
-Therefore **do not delete them** by yourself.
-
-You should call `AddGlobalTestEnvironment()` before `RUN_ALL_TESTS()` is called,
-probably in `main()`. If you use `gtest_main`, you need to call this before
-`main()` starts for it to take effect. One way to do this is to define a global
-variable like this:
-
-```c++
-::testing::Environment* const foo_env =
-    ::testing::AddGlobalTestEnvironment(new FooEnvironment);
-```
-
-However, we strongly recommend you to write your own `main()` and call
-`AddGlobalTestEnvironment()` there, as relying on initialization of global
-variables makes the code harder to read and may cause problems when you register
-multiple environments from different translation units and the environments have
-dependencies among them (remember that the compiler doesn't guarantee the order
-in which global variables from different translation units are initialized).
-
-## Value-Parameterized Tests
-
-*Value-parameterized tests* allow you to test your code with different
-parameters without writing multiple copies of the same test. This is useful in a
-number of situations, for example:
-
-*   You have a piece of code whose behavior is affected by one or more
-    command-line flags. You want to make sure your code performs correctly for
-    various values of those flags.
-*   You want to test different implementations of an OO interface.
-*   You want to test your code over various inputs (a.k.a. data-driven testing).
-    This feature is easy to abuse, so please exercise your good sense when doing
-    it!
-
-### How to Write Value-Parameterized Tests
-
-To write value-parameterized tests, first you should define a fixture class. It
-must be derived from both `testing::Test` and `testing::WithParamInterface<T>`
-(the latter is a pure interface), where `T` is the type of your parameter
-values. For convenience, you can just derive the fixture class from
-`testing::TestWithParam<T>`, which itself is derived from both `testing::Test`
-and `testing::WithParamInterface<T>`. `T` can be any copyable type. If it's a
-raw pointer, you are responsible for managing the lifespan of the pointed
-values.
-
-NOTE: If your test fixture defines `SetUpTestSuite()` or `TearDownTestSuite()`
-they must be declared **public** rather than **protected** in order to use
-`TEST_P`.
-
-```c++
-class FooTest :
-    public testing::TestWithParam<const char*> {
-  // You can implement all the usual fixture class members here.
-  // To access the test parameter, call GetParam() from class
-  // TestWithParam<T>.
-};
-
-// Or, when you want to add parameters to a pre-existing fixture class:
-class BaseTest : public testing::Test {
-  ...
-};
-class BarTest : public BaseTest,
-                public testing::WithParamInterface<const char*> {
-  ...
-};
-```
-
-Then, use the `TEST_P` macro to define as many test patterns using this fixture
-as you want. The `_P` suffix is for "parameterized" or "pattern", whichever you
-prefer to think.
-
-```c++
-TEST_P(FooTest, DoesBlah) {
-  // Inside a test, access the test parameter with the GetParam() method
-  // of the TestWithParam<T> class:
-  EXPECT_TRUE(foo.Blah(GetParam()));
-  ...
-}
-
-TEST_P(FooTest, HasBlahBlah) {
-  ...
-}
-```
-
-Finally, you can use `INSTANTIATE_TEST_SUITE_P` to instantiate the test suite
-with any set of parameters you want. googletest defines a number of functions
-for generating test parameters. They return what we call (surprise!) *parameter
-generators*. Here is a summary of them, which are all in the `testing`
-namespace:

-
-The following statement will instantiate tests from the `FooTest` test suite
-each with parameter values `"meeny"`, `"miny"`, and `"moe"`.
-
-```c++
-INSTANTIATE_TEST_SUITE_P(InstantiationName,
-                         FooTest,
-                         testing::Values("meeny", "miny", "moe"));
-```
-
-NOTE: The code above must be placed at global or namespace scope, not at
-function scope.
-
-NOTE: Don't forget this step! If you do your test will silently pass, but none
-of its suites will ever run!
-
-To distinguish different instances of the pattern (yes, you can instantiate it
-more than once), the first argument to `INSTANTIATE_TEST_SUITE_P` is a prefix
-that will be added to the actual test suite name. Remember to pick unique
-prefixes for different instantiations. The tests from the instantiation above
-will have these names:
-
-*   `InstantiationName/FooTest.DoesBlah/0` for `"meeny"`
-*   `InstantiationName/FooTest.DoesBlah/1` for `"miny"`
-*   `InstantiationName/FooTest.DoesBlah/2` for `"moe"`
-*   `InstantiationName/FooTest.HasBlahBlah/0` for `"meeny"`
-*   `InstantiationName/FooTest.HasBlahBlah/1` for `"miny"`
-*   `InstantiationName/FooTest.HasBlahBlah/2` for `"moe"`
-
-You can use these names in [`--gtest_filter`](#running-a-subset-of-the-tests).
-
-This statement will instantiate all tests from `FooTest` again, each with
-parameter values `"cat"` and `"dog"`:
-
-```c++
-const char* pets[] = {"cat", "dog"};
-INSTANTIATE_TEST_SUITE_P(AnotherInstantiationName, FooTest,
-                         testing::ValuesIn(pets));

-
-The tests from the instantiation above will have these names:
-
-*   `AnotherInstantiationName/FooTest.DoesBlah/0` for `"cat"`
-*   `AnotherInstantiationName/FooTest.DoesBlah/1` for `"dog"`
-*   `AnotherInstantiationName/FooTest.HasBlahBlah/0` for `"cat"`
-*   `AnotherInstantiationName/FooTest.HasBlahBlah/1` for `"dog"`
-
-Please note that `INSTANTIATE_TEST_SUITE_P` will instantiate *all* tests in the
-given test suite, whether their definitions come before or *after* the
-`INSTANTIATE_TEST_SUITE_P` statement.

-### Creating Value-Parameterized Abstract Tests
-
-In the above, we define and instantiate `FooTest` in the *same* source file.
-Sometimes you may want to define value-parameterized tests in a library and let
-other people instantiate them later. This pattern is known as *abstract tests*.
-As an example of its application, when you are designing an interface you can
-write a standard suite of abstract tests (perhaps using a factory function as
-the test parameter) that all implementations of the interface are expected to
-pass. When someone implements the interface, they can instantiate your suite to
-get all the interface-conformance tests for free.
-
-To define abstract tests, you should organize your code like this:
-
-1.  Put the definition of the parameterized test fixture class (e.g. `FooTest`)
-    in a header file, say `foo_param_test.h`. Think of this as *declaring* your
-    abstract tests.
-2.  Put the `TEST_P` definitions in `foo_param_test.cc`, which includes
-    `foo_param_test.h`. Think of this as *implementing* your abstract tests.
-
-Once they are defined, you can instantiate them by including `foo_param_test.h`,
-invoking `INSTANTIATE_TEST_SUITE_P()`, and depending on the library target that
-contains `foo_param_test.cc`. You can instantiate the same abstract test suite
-multiple times, possibly in different source files.
-
-### Specifying Names for Value-Parameterized Test Parameters
-
-The optional last argument to `INSTANTIATE_TEST_SUITE_P()` allows the user to
-specify a function or functor that generates custom test name suffixes based on
-the test parameters. The function should accept one argument of type
-`testing::TestParamInfo<class ParamType>`, and return `std::string`.
-
-`testing::PrintToStringParamName` is a builtin test suffix generator that
-returns the value of `testing::PrintToString(GetParam())`. It does not work for
-`std::string` or C strings.
-
-NOTE: test names must be non-empty, unique, and may only contain ASCII
-alphanumeric characters. In particular, they
-[should not contain underscores](faq.md#why-should-test-suite-names-and-test-names-not-contain-underscore)
-
-```c++
-class MyTestSuite : public testing::TestWithParam<int> {};
-
-TEST_P(MyTestSuite, MyTest)
-{
-  std::cout << "Example Test Param: " << GetParam() << std::endl;
-}
-
-INSTANTIATE_TEST_SUITE_P(MyGroup, MyTestSuite, testing::Range(0, 10),
-                         testing::PrintToStringParamName());
-```
-
-Providing a custom functor allows for more control over test parameter name
-generation, especially for types where the automatic conversion does not
-generate helpful parameter names (e.g. strings as demonstrated above). The
-following example illustrates this for multiple parameters, an enumeration type
-and a string, and also demonstrates how to combine generators. It uses a lambda
-for conciseness:
-
-```c++
-enum class MyType { MY_FOO = 0, MY_BAR = 1 };
-
-class MyTestSuite : public testing::TestWithParam<std::tuple<MyType, string>> {
-};
-
-INSTANTIATE_TEST_SUITE_P(
-    MyGroup, MyTestSuite,
-    testing::Combine(
-        testing::Values(MyType::VALUE_0, MyType::VALUE_1),
-        testing::ValuesIn("", "")),
-    [](const testing::TestParamInfo<MyTestSuite::ParamType>& info) {
-      string name = absl::StrCat(
-          std::get<0>(info.param) == MY_FOO ? "Foo" : "Bar", "_",
-          std::get<1>(info.param));
-      absl::c_replace_if(name, [](char c) { return !std::isalnum(c); }, '_');
-      return name;
-    });
-```
-
-## Typed Tests
-
-Suppose you have multiple implementations of the same interface and want to make
-sure that all of them satisfy some common requirements. Or, you may have defined
-several types that are supposed to conform to the same "concept" and you want to
-verify it. In both cases, you want the same test logic repeated for different
-types.
-
-While you can write one `TEST` or `TEST_F` for each type you want to test (and
-you may even factor the test logic into a function template that you invoke from
-the `TEST`), it's tedious and doesn't scale: if you want `m` tests over `n`
-types, you'll end up writing `m*n` `TEST`s.
-
-*Typed tests* allow you to repeat the same test logic over a list of types. You
-only need to write the test logic once, although you must know the type list
-when writing typed tests. Here's how you do it:
-
-First, define a fixture class template. It should be parameterized by a type.
-Remember to derive it from `::testing::Test`:
-
-```c++
-template <typename T>
-class FooTest : public ::testing::Test {
- public:
-  ...
-  typedef std::list<T> List;
-  static T shared_;
-  T value_;
-};
-```
-
-Next, associate a list of types with the test suite, which will be repeated for
-each type in the list:
-
-```c++
-using MyTypes = ::testing::Types<char, int, unsigned int>;
-TYPED_TEST_SUITE(FooTest, MyTypes);
-```
-
-The type alias (`using` or `typedef`) is necessary for the `TYPED_TEST_SUITE`
-macro to parse correctly. Otherwise the compiler will think that each comma in
-the type list introduces a new macro argument.
-
-Then, use `TYPED_TEST()` instead of `TEST_F()` to define a typed test for this
-test suite. You can repeat this as many times as you want:
-
-```c++
-TYPED_TEST(FooTest, DoesBlah) {
-  // Inside a test, refer to the special name TypeParam to get the type
-  // parameter.  Since we are inside a derived class template, C++ requires
-  // us to visit the members of FooTest via 'this'.
-  TypeParam n = this->value_;
-
-  // To visit static members of the fixture, add the 'TestFixture::'
-  // prefix.
-  n += TestFixture::shared_;
-
-  // To refer to typedefs in the fixture, add the 'typename TestFixture::'
-  // prefix.  The 'typename' is required to satisfy the compiler.
-  typename TestFixture::List values;
-
-  values.push_back(n);
-  ...
-}
-
-TYPED_TEST(FooTest, HasPropertyA) { ... }
-```
-
-You can see [sample6_unittest.cc] for a complete example.
-
-[sample6_unittest.cc]: ../samples/sample6_unittest.cc "Typed Test example"
-
-## Type-Parameterized Tests
-
-*Type-parameterized tests* are like typed tests, except that they don't require
-you to know the list of types ahead of time. Instead, you can define the test
-logic first and instantiate it with different type lists later. You can even
-instantiate it more than once in the same program.
-
-If you are designing an interface or concept, you can define a suite of
-type-parameterized tests to verify properties that any valid implementation of
-the interface/concept should have. Then, the author of each implementation can
-just instantiate the test suite with their type to verify that it conforms to
-the requirements, without having to write similar tests repeatedly. Here's an
-example:
-
-First, define a fixture class template, as we did with typed tests:
-
-```c++
-template <typename T>
-class FooTest : public ::testing::Test {
-  ...
-};
-```
-
-Next, declare that you will define a type-parameterized test suite:
-
-```c++
-TYPED_TEST_SUITE_P(FooTest);
-```
-
-Then, use `TYPED_TEST_P()` to define a type-parameterized test. You can repeat
-this as many times as you want:
-
-```c++
-TYPED_TEST_P(FooTest, DoesBlah) {
-  // Inside a test, refer to TypeParam to get the type parameter.
-  TypeParam n = 0;
-  ...
-}
-
-TYPED_TEST_P(FooTest, HasPropertyA) { ... }
-```
-
-Now the tricky part: you need to register all test patterns using the
-`REGISTER_TYPED_TEST_SUITE_P` macro before you can instantiate them. The first
-argument of the macro is the test suite name; the rest are the names of the
-tests in this test suite:
-
-```c++
-REGISTER_TYPED_TEST_SUITE_P(FooTest,
-                            DoesBlah, HasPropertyA);
-```
-
-Finally, you are free to instantiate the pattern with the types you want. If you
-put the above code in a header file, you can `#include` it in multiple C++
-source files and instantiate it multiple times.
-
-```c++
-typedef ::testing::Types<char, int, unsigned int> MyTypes;
-INSTANTIATE_TYPED_TEST_SUITE_P(My, FooTest, MyTypes);
-```
-
-To distinguish different instances of the pattern, the first argument to the
-`INSTANTIATE_TYPED_TEST_SUITE_P` macro is a prefix that will be added to the
-actual test suite name. Remember to pick unique prefixes for different
-instances.
-
-In the special case where the type list contains only one type, you can write
-that type directly without `::testing::Types<...>`, like this:
-
-```c++
-INSTANTIATE_TYPED_TEST_SUITE_P(My, FooTest, int);
-```
-
-You can see [sample6_unittest.cc] for a complete example.
-
-## Testing Private Code
-
-If you change your software's internal implementation, your tests should not
-break as long as the change is not observable by users. Therefore, **per the
-black-box testing principle, most of the time you should test your code through
-its public interfaces.**
-
-**If you still find yourself needing to test internal implementation code,
-consider if there's a better design.** The desire to test internal
-implementation is often a sign that the class is doing too much. Consider
-extracting an implementation class, and testing it. Then use that implementation
-class in the original class.
-
-If you absolutely have to test non-public interface code though, you can. There
-are two cases to consider:
-
-*   Static functions ( *not* the same as static member functions!) or unnamed
-    namespaces, and
-*   Private or protected class members
-
-To test them, we use the following special techniques:
-
-*   Both static functions and definitions/declarations in an unnamed namespace
-    are only visible within the same translation unit. To test them, you can
-    `#include` the entire `.cc` file being tested in your `*_test.cc` file.
-    (#including `.cc` files is not a good way to reuse code - you should not do
-    this in production code!)
-
-    However, a better approach is to move the private code into the
-    `foo::internal` namespace, where `foo` is the namespace your project
-    normally uses, and put the private declarations in a `*-internal.h` file.
-    Your production `.cc` files and your tests are allowed to include this
-    internal header, but your clients are not. This way, you can fully test your
-    internal implementation without leaking it to your clients.
-
-*   Private class members are only accessible from within the class or by
-    friends. To access a class' private members, you can declare your test
-    fixture as a friend to the class and define accessors in your fixture. Tests
-    using the fixture can then access the private members of your production
-    class via the accessors in the fixture. Note that even though your fixture
-    is a friend to your production class, your tests are not automatically
-    friends to it, as they are technically defined in sub-classes of the
-    fixture.
-
-    Another way to test private members is to refactor them into an
-    implementation class, which is then declared in a `*-internal.h` file. Your
-    clients aren't allowed to include this header but your tests can. Such is
-    called the
-    [Pimpl](https://www.gamedev.net/articles/programming/general-and-gameplay-programming/the-c-pimpl-r1794/)
-    (Private Implementation) idiom.
-
-    Or, you can declare an individual test as a friend of your class by adding
-    this line in the class body:
-
-    ```c++
-        FRIEND_TEST(TestSuiteName, TestName);
-    ```
-
-    For example,
-
-    ```c++
-    // foo.h
-    class Foo {
-      ...
-     private:
-      FRIEND_TEST(FooTest, BarReturnsZeroOnNull);
-
-      int Bar(void* x);
-    };
-
-    // foo_test.cc
-    ...
-    TEST(FooTest, BarReturnsZeroOnNull) {
-      Foo foo;
-      EXPECT_EQ(foo.Bar(NULL), 0);  // Uses Foo's private member Bar().
-    }
-    ```
-
-    Pay special attention when your class is defined in a namespace, as you
-    should define your test fixtures and tests in the same namespace if you want
-    them to be friends of your class. For example, if the code to be tested
-    looks like:
-
-    ```c++
-    namespace my_namespace {
-
-    class Foo {
-      friend class FooTest;
-      FRIEND_TEST(FooTest, Bar);
-      FRIEND_TEST(FooTest, Baz);
-      ... definition of the class Foo ...
-    };
-
-    }  // namespace my_namespace
-    ```
-
-    Your test code should be something like:
-
-    ```c++
-    namespace my_namespace {
-
-    class FooTest : public ::testing::Test {
-     protected:
-      ...
-    };
-
-    TEST_F(FooTest, Bar) { ... }
-    TEST_F(FooTest, Baz) { ... }
-
-    }  // namespace my_namespace
-    ```
-
-## "Catching" Failures
-
-If you are building a testing utility on top of googletest, you'll want to test
-your utility. What framework would you use to test it? googletest, of course.
-
-The challenge is to verify that your testing utility reports failures correctly.
-In frameworks that report a failure by throwing an exception, you could catch
-the exception and assert on it. But googletest doesn't use exceptions, so how do
-we test that a piece of code generates an expected failure?
-
-gunit-spi.h contains some constructs to do this. After #including this header,
-you can use
-
-```c++
-  EXPECT_FATAL_FAILURE(statement, substring);
-```
-
-to assert that `statement` generates a fatal (e.g. `ASSERT_*`) failure in the
-current thread whose message contains the given `substring`, or use
-
-```c++
-  EXPECT_NONFATAL_FAILURE(statement, substring);
-```
-
-if you are expecting a non-fatal (e.g. `EXPECT_*`) failure.
-
-Only failures in the current thread are checked to determine the result of this
-type of expectations. If `statement` creates new threads, failures in these
-threads are also ignored. If you want to catch failures in other threads as
-well, use one of the following macros instead:
-
-```c++
-  EXPECT_FATAL_FAILURE_ON_ALL_THREADS(statement, substring);
-  EXPECT_NONFATAL_FAILURE_ON_ALL_THREADS(statement, substring);
-```
-
-NOTE: Assertions from multiple threads are currently not supported on Windows.
-
-For technical reasons, there are some caveats:
-
-1.  You cannot stream a failure message to either macro.
-
-2.  `statement` in `EXPECT_FATAL_FAILURE{_ON_ALL_THREADS}()` cannot reference
-    local non-static variables or non-static members of `this` object.
-
-3.  `statement` in `EXPECT_FATAL_FAILURE{_ON_ALL_THREADS}()` cannot return a
-    value.
-
-## Registering tests programmatically
-
-The `TEST` macros handle the vast majority of all use cases, but there are few
-were runtime registration logic is required. For those cases, the framework
-provides the `::testing::RegisterTest` that allows callers to register arbitrary
-tests dynamically.
-
-This is an advanced API only to be used when the `TEST` macros are insufficient.
-The macros should be preferred when possible, as they avoid most of the
-complexity of calling this function.
-
-It provides the following signature:
-
-```c++
-template <typename Factory>
-TestInfo* RegisterTest(const char* test_suite_name, const char* test_name,
-                       const char* type_param, const char* value_param,
-                       const char* file, int line, Factory factory);
-```
-
-The `factory` argument is a factory callable (move-constructible) object or
-function pointer that creates a new instance of the Test object. It handles
-ownership to the caller. The signature of the callable is `Fixture*()`, where
-`Fixture` is the test fixture class for the test. All tests registered with the
-same `test_suite_name` must return the same fixture type. This is checked at
-runtime.
-
-The framework will infer the fixture class from the factory and will call the
-`SetUpTestSuite` and `TearDownTestSuite` for it.
-
-Must be called before `RUN_ALL_TESTS()` is invoked, otherwise behavior is
-undefined.
-
-Use case example:
-
-```c++
-class MyFixture : public ::testing::Test {
- public:
-  // All of these optional, just like in regular macro usage.
-  static void SetUpTestSuite() { ... }
-  static void TearDownTestSuite() { ... }
-  void SetUp() override { ... }
-  void TearDown() override { ... }
-};
-
-class MyTest : public MyFixture {
- public:
-  explicit MyTest(int data) : data_(data) {}
-  void TestBody() override { ... }
-
- private:
-  int data_;
-};
-
-void RegisterMyTests(const std::vector<int>& values) {
-  for (int v : values) {
-    ::testing::RegisterTest(
-        "MyFixture", ("Test" + std::to_string(v)).c_str(), nullptr,
-        std::to_string(v).c_str(),
-        __FILE__, __LINE__,
-        // Important to use the fixture type as the return type here.
-        [=]() -> MyFixture* { return new MyTest(v); });
-  }
-}
-...
-int main(int argc, char** argv) {
-  std::vector<int> values_to_test = LoadValuesFromConfig();
-  RegisterMyTests(values_to_test);
-  ...
-  return RUN_ALL_TESTS();
-}
-```
-## Getting the Current Test's Name
-
-Sometimes a function may need to know the name of the currently running test.
-For example, you may be using the `SetUp()` method of your test fixture to set
-the golden file name based on which test is running. The `::testing::TestInfo`
-class has this information:
-
-```c++
-namespace testing {
-
-class TestInfo {
- public:
-  // Returns the test suite name and the test name, respectively.
-  //
-  // Do NOT delete or free the return value - it's managed by the
-  // TestInfo class.
-  const char* test_suite_name() const;
-  const char* name() const;
-};
-
-}
-```
-
-To obtain a `TestInfo` object for the currently running test, call
-`current_test_info()` on the `UnitTest` singleton object:
-
-```c++
-  // Gets information about the currently running test.
-  // Do NOT delete the returned object - it's managed by the UnitTest class.
-  const ::testing::TestInfo* const test_info =
-    ::testing::UnitTest::GetInstance()->current_test_info();
-
-
-
-  printf("We are in test %s of test suite %s.\n",
-         test_info->name(),
-         test_info->test_suite_name());
-```
-
-`current_test_info()` returns a null pointer if no test is running. In
-particular, you cannot find the test suite name in `TestSuiteSetUp()`,
-`TestSuiteTearDown()` (where you know the test suite name implicitly), or
-functions called from them.
-
-## Extending googletest by Handling Test Events
-
-googletest provides an **event listener API** to let you receive notifications
-about the progress of a test program and test failures. The events you can
-listen to include the start and end of the test program, a test suite, or a test
-method, among others. You may use this API to augment or replace the standard
-console output, replace the XML output, or provide a completely different form
-of output, such as a GUI or a database. You can also use test events as
-checkpoints to implement a resource leak checker, for example.
-
-### Defining Event Listeners
-
-To define a event listener, you subclass either testing::TestEventListener or
-testing::EmptyTestEventListener The former is an (abstract) interface, where
-*each pure virtual method can be overridden to handle a test event* (For
-example, when a test starts, the `OnTestStart()` method will be called.). The
-latter provides an empty implementation of all methods in the interface, such
-that a subclass only needs to override the methods it cares about.
-
-When an event is fired, its context is passed to the handler function as an
-argument. The following argument types are used:
-
-*   UnitTest reflects the state of the entire test program,
-*   TestSuite has information about a test suite, which can contain one or more
-    tests,
-*   TestInfo contains the state of a test, and
-*   TestPartResult represents the result of a test assertion.
-
-An event handler function can examine the argument it receives to find out
-interesting information about the event and the test program's state.
-
-Here's an example:
-
-```c++
-  class MinimalistPrinter : public ::testing::EmptyTestEventListener {
-    // Called before a test starts.
-    virtual void OnTestStart(const ::testing::TestInfo& test_info) {
-      printf("*** Test %s.%s starting.\n",
-             test_info.test_suite_name(), test_info.name());
-    }
-
-    // Called after a failed assertion or a SUCCESS().
-    virtual void OnTestPartResult(const ::testing::TestPartResult& test_part_result) {
-      printf("%s in %s:%d\n%s\n",
-             test_part_result.failed() ? "*** Failure" : "Success",
-             test_part_result.file_name(),
-             test_part_result.line_number(),
-             test_part_result.summary());
-    }
-
-    // Called after a test ends.
-    virtual void OnTestEnd(const ::testing::TestInfo& test_info) {
-      printf("*** Test %s.%s ending.\n",
-             test_info.test_suite_name(), test_info.name());
-    }
-  };
-```
-
-### Using Event Listeners
-
-To use the event listener you have defined, add an instance of it to the
-googletest event listener list (represented by class TestEventListeners - note
-the "s" at the end of the name) in your `main()` function, before calling
-`RUN_ALL_TESTS()`:
-
-```c++
-int main(int argc, char** argv) {
-  ::testing::InitGoogleTest(&argc, argv);
-  // Gets hold of the event listener list.
-  ::testing::TestEventListeners& listeners =
-        ::testing::UnitTest::GetInstance()->listeners();
-  // Adds a listener to the end.  googletest takes the ownership.
-  listeners.Append(new MinimalistPrinter);
-  return RUN_ALL_TESTS();
-}
-```
-
-There's only one problem: the default test result printer is still in effect, so
-its output will mingle with the output from your minimalist printer. To suppress
-the default printer, just release it from the event listener list and delete it.
-You can do so by adding one line:
-
-```c++
-  ...
-  delete listeners.Release(listeners.default_result_printer());
-  listeners.Append(new MinimalistPrinter);
-  return RUN_ALL_TESTS();
-```
-
-Now, sit back and enjoy a completely different output from your tests. For more
-details, see [sample9_unittest.cc].
-
-[sample9_unittest.cc]: ../samples/sample9_unittest.cc "Event listener example"
-
-You may append more than one listener to the list. When an `On*Start()` or
-`OnTestPartResult()` event is fired, the listeners will receive it in the order
-they appear in the list (since new listeners are added to the end of the list,
-the default text printer and the default XML generator will receive the event
-first). An `On*End()` event will be received by the listeners in the *reverse*
-order. This allows output by listeners added later to be framed by output from
-listeners added earlier.
-
-### Generating Failures in Listeners
-
-You may use failure-raising macros (`EXPECT_*()`, `ASSERT_*()`, `FAIL()`, etc)
-when processing an event. There are some restrictions:
-
-1.  You cannot generate any failure in `OnTestPartResult()` (otherwise it will
-    cause `OnTestPartResult()` to be called recursively).
-2.  A listener that handles `OnTestPartResult()` is not allowed to generate any
-    failure.
-
-When you add listeners to the listener list, you should put listeners that
-handle `OnTestPartResult()` *before* listeners that can generate failures. This
-ensures that failures generated by the latter are attributed to the right test
-by the former.
-
-See [sample10_unittest.cc] for an example of a failure-raising listener.
-
-[sample10_unittest.cc]: ../samples/sample10_unittest.cc "Failure-raising listener example"
-
-## Running Test Programs: Advanced Options
-
-googletest test programs are ordinary executables. Once built, you can run them
-directly and affect their behavior via the following environment variables
-and/or command line flags. For the flags to work, your programs must call
-`::testing::InitGoogleTest()` before calling `RUN_ALL_TESTS()`.
-
-To see a list of supported flags and their usage, please run your test program
-with the `--help` flag. You can also use `-h`, `-?`, or `/?` for short.
-
-If an option is specified both by an environment variable and by a flag, the
-latter takes precedence.
-
-### Selecting Tests
-
-#### Listing Test Names
-
-Sometimes it is necessary to list the available tests in a program before
-running them so that a filter may be applied if needed. Including the flag
-`--gtest_list_tests` overrides all other flags and lists tests in the following
-format:
-
-```none
-TestSuite1.
-  TestName1
-  TestName2
-TestSuite2.
-  TestName
-```
-
-None of the tests listed are actually run if the flag is provided. There is no
-corresponding environment variable for this flag.
-
-#### Running a Subset of the Tests
-
-By default, a googletest program runs all tests the user has defined. Sometimes,
-you want to run only a subset of the tests (e.g. for debugging or quickly
-verifying a change). If you set the `GTEST_FILTER` environment variable or the
-`--gtest_filter` flag to a filter string, googletest will only run the tests
-whose full names (in the form of `TestSuiteName.TestName`) match the filter.
-
-The format of a filter is a '`:`'-separated list of wildcard patterns (called
-the *positive patterns*) optionally followed by a '`-`' and another
-'`:`'-separated pattern list (called the *negative patterns*). A test matches
-the filter if and only if it matches any of the positive patterns but does not
-match any of the negative patterns.
-
-A pattern may contain `'*'` (matches any string) or `'?'` (matches any single
-character). For convenience, the filter `'*-NegativePatterns'` can be also
-written as `'-NegativePatterns'`.
-
-For example:
-
-*   `./foo_test` Has no flag, and thus runs all its tests.
-*   `./foo_test --gtest_filter=*` Also runs everything, due to the single
-    match-everything `*` value.
-*   `./foo_test --gtest_filter=FooTest.*` Runs everything in test suite
-    `FooTest` .
-*   `./foo_test --gtest_filter=*Null*:*Constructor*` Runs any test whose full
-    name contains either `"Null"` or `"Constructor"` .
-*   `./foo_test --gtest_filter=-*DeathTest.*` Runs all non-death tests.
-*   `./foo_test --gtest_filter=FooTest.*-FooTest.Bar` Runs everything in test
-    suite `FooTest` except `FooTest.Bar`.
-*   `./foo_test --gtest_filter=FooTest.*:BarTest.*-FooTest.Bar:BarTest.Foo` Runs
-    everything in test suite `FooTest` except `FooTest.Bar` and everything in
-    test suite `BarTest` except `BarTest.Foo`.
-
-#### Temporarily Disabling Tests
-
-If you have a broken test that you cannot fix right away, you can add the
-`DISABLED_` prefix to its name. This will exclude it from execution. This is
-better than commenting out the code or using `#if 0`, as disabled tests are
-still compiled (and thus won't rot).
-
-If you need to disable all tests in a test suite, you can either add `DISABLED_`
-to the front of the name of each test, or alternatively add it to the front of
-the test suite name.
-
-For example, the following tests won't be run by googletest, even though they
-will still be compiled:
-
-```c++
-// Tests that Foo does Abc.
-TEST(FooTest, DISABLED_DoesAbc) { ... }
-
-class DISABLED_BarTest : public ::testing::Test { ... };
-
-// Tests that Bar does Xyz.
-TEST_F(DISABLED_BarTest, DoesXyz) { ... }
-```
-
-NOTE: This feature should only be used for temporary pain-relief. You still have
-to fix the disabled tests at a later date. As a reminder, googletest will print
-a banner warning you if a test program contains any disabled tests.
-
-TIP: You can easily count the number of disabled tests you have using `gsearch`
-and/or `grep`. This number can be used as a metric for improving your test
-quality.
-
-#### Temporarily Enabling Disabled Tests
-
-To include disabled tests in test execution, just invoke the test program with
-the `--gtest_also_run_disabled_tests` flag or set the
-`GTEST_ALSO_RUN_DISABLED_TESTS` environment variable to a value other than `0`.
-You can combine this with the `--gtest_filter` flag to further select which
-disabled tests to run.
-
-### Repeating the Tests
-
-Once in a while you'll run into a test whose result is hit-or-miss. Perhaps it
-will fail only 1% of the time, making it rather hard to reproduce the bug under
-a debugger. This can be a major source of frustration.
-
-The `--gtest_repeat` flag allows you to repeat all (or selected) test methods in
-a program many times. Hopefully, a flaky test will eventually fail and give you
-a chance to debug. Here's how to use it:
-
-```none
-$ foo_test --gtest_repeat=1000
-Repeat foo_test 1000 times and don't stop at failures.
-
-$ foo_test --gtest_repeat=-1
-A negative count means repeating forever.
-
-$ foo_test --gtest_repeat=1000 --gtest_break_on_failure
-Repeat foo_test 1000 times, stopping at the first failure.  This
-is especially useful when running under a debugger: when the test
-fails, it will drop into the debugger and you can then inspect
-variables and stacks.
-
-$ foo_test --gtest_repeat=1000 --gtest_filter=FooBar.*
-Repeat the tests whose name matches the filter 1000 times.
-```
-
-If your test program contains
-[global set-up/tear-down](#global-set-up-and-tear-down) code, it will be
-repeated in each iteration as well, as the flakiness may be in it. You can also
-specify the repeat count by setting the `GTEST_REPEAT` environment variable.
-
-### Shuffling the Tests
-
-You can specify the `--gtest_shuffle` flag (or set the `GTEST_SHUFFLE`
-environment variable to `1`) to run the tests in a program in a random order.
-This helps to reveal bad dependencies between tests.
-
-By default, googletest uses a random seed calculated from the current time.
-Therefore you'll get a different order every time. The console output includes
-the random seed value, such that you can reproduce an order-related test failure
-later. To specify the random seed explicitly, use the `--gtest_random_seed=SEED`
-flag (or set the `GTEST_RANDOM_SEED` environment variable), where `SEED` is an
-integer in the range [0, 99999]. The seed value 0 is special: it tells
-googletest to do the default behavior of calculating the seed from the current
-time.
-
-If you combine this with `--gtest_repeat=N`, googletest will pick a different
-random seed and re-shuffle the tests in each iteration.
-
-### Controlling Test Output
-
-#### Colored Terminal Output
-
-googletest can use colors in its terminal output to make it easier to spot the
-important information:
-
-<code>
-...<br/>
-  <font color="green">[----------]</font><font color="black"> 1 test from
-  FooTest</font><br/>
-  <font color="green">[ RUN &nbsp; &nbsp; &nbsp;]</font><font color="black">
-  FooTest.DoesAbc</font><br/>
-  <font color="green">[ &nbsp; &nbsp; &nbsp; OK ]</font><font color="black">
-  FooTest.DoesAbc </font><br/>
-  <font color="green">[----------]</font><font color="black">
-  2 tests from BarTest</font><br/>
-  <font color="green">[ RUN &nbsp; &nbsp; &nbsp;]</font><font color="black">
-  BarTest.HasXyzProperty </font><br/>
-  <font color="green">[ &nbsp; &nbsp; &nbsp; OK ]</font><font color="black">
-  BarTest.HasXyzProperty</font><br/>
-  <font color="green">[ RUN &nbsp; &nbsp; &nbsp;]</font><font color="black">
-  BarTest.ReturnsTrueOnSuccess ... some error messages ...</font><br/>
-  <font color="red">[ &nbsp; FAILED ]</font><font color="black">
-  BarTest.ReturnsTrueOnSuccess ...</font><br/>
-  <font color="green">[==========]</font><font color="black">
-  30 tests from 14 test suites ran.</font><br/>
-  <font color="green">[ &nbsp; PASSED ]</font><font color="black">
-  28 tests.</font><br/>
-  <font color="red">[ &nbsp; FAILED ]</font><font color="black">
-  2 tests, listed below:</font><br/>
-  <font color="red">[ &nbsp; FAILED ]</font><font color="black">
-  BarTest.ReturnsTrueOnSuccess</font><br/>
-  <font color="red">[ &nbsp; FAILED ]</font><font color="black">
-  AnotherTest.DoesXyz<br/>
-<br/>
-  2 FAILED TESTS
-  </font>
-</code>
-
-You can set the `GTEST_COLOR` environment variable or the `--gtest_color`
-command line flag to `yes`, `no`, or `auto` (the default) to enable colors,
-disable colors, or let googletest decide. When the value is `auto`, googletest
-will use colors if and only if the output goes to a terminal and (on non-Windows
-platforms) the `TERM` environment variable is set to `xterm` or `xterm-color`.
-
-#### Suppressing the Elapsed Time
-
-By default, googletest prints the time it takes to run each test. To disable
-that, run the test program with the `--gtest_print_time=0` command line flag, or
-set the GTEST_PRINT_TIME environment variable to `0`.
-
-#### Suppressing UTF-8 Text Output
-
-In case of assertion failures, googletest prints expected and actual values of
-type `string` both as hex-encoded strings as well as in readable UTF-8 text if
-they contain valid non-ASCII UTF-8 characters. If you want to suppress the UTF-8
-text because, for example, you don't have an UTF-8 compatible output medium, run
-the test program with `--gtest_print_utf8=0` or set the `GTEST_PRINT_UTF8`
-environment variable to `0`.
-
-
-
-#### Generating an XML Report
-
-googletest can emit a detailed XML report to a file in addition to its normal
-textual output. The report contains the duration of each test, and thus can help
-you identify slow tests. The report is also used by the http://unittest
-dashboard to show per-test-method error messages.
-
-To generate the XML report, set the `GTEST_OUTPUT` environment variable or the
-`--gtest_output` flag to the string `"xml:path_to_output_file"`, which will
-create the file at the given location. You can also just use the string `"xml"`,
-in which case the output can be found in the `test_detail.xml` file in the
-current directory.
-
-If you specify a directory (for example, `"xml:output/directory/"` on Linux or
-`"xml:output\directory\"` on Windows), googletest will create the XML file in
-that directory, named after the test executable (e.g. `foo_test.xml` for test
-program `foo_test` or `foo_test.exe`). If the file already exists (perhaps left
-over from a previous run), googletest will pick a different name (e.g.
-`foo_test_1.xml`) to avoid overwriting it.
-
-The report is based on the `junitreport` Ant task. Since that format was
-originally intended for Java, a little interpretation is required to make it
-apply to googletest tests, as shown here:
-
-```xml
-<testsuites name="AllTests" ...>
-  <testsuite name="test_case_name" ...>
-    <testcase    name="test_name" ...>
-      <failure message="..."/>
-      <failure message="..."/>
-      <failure message="..."/>
-    </testcase>
-  </testsuite>
-</testsuites>
-```
-
-*   The root `<testsuites>` element corresponds to the entire test program.
-*   `<testsuite>` elements correspond to googletest test suites.
-*   `<testcase>` elements correspond to googletest test functions.
-
-For instance, the following program
-
-```c++
-TEST(MathTest, Addition) { ... }
-TEST(MathTest, Subtraction) { ... }
-TEST(LogicTest, NonContradiction) { ... }
-```
-
-could generate this report:
-
-```xml
-<?xml version="1.0" encoding="UTF-8"?>
-<testsuites tests="3" failures="1" errors="0" time="0.035" timestamp="2011-10-31T18:52:42" name="AllTests">
-  <testsuite name="MathTest" tests="2" failures="1" errors="0" time="0.015">
-    <testcase name="Addition" status="run" time="0.007" classname="">
-      <failure message="Value of: add(1, 1)&#x0A;  Actual: 3&#x0A;Expected: 2" type="">...</failure>
-      <failure message="Value of: add(1, -1)&#x0A;  Actual: 1&#x0A;Expected: 0" type="">...</failure>
-    </testcase>
-    <testcase name="Subtraction" status="run" time="0.005" classname="">
-    </testcase>
-  </testsuite>
-  <testsuite name="LogicTest" tests="1" failures="0" errors="0" time="0.005">
-    <testcase name="NonContradiction" status="run" time="0.005" classname="">
-    </testcase>
-  </testsuite>
-</testsuites>
-```
-
-Things to note:
-
-*   The `tests` attribute of a `<testsuites>` or `<testsuite>` element tells how
-    many test functions the googletest program or test suite contains, while the
-    `failures` attribute tells how many of them failed.
-
-*   The `time` attribute expresses the duration of the test, test suite, or
-    entire test program in seconds.
-
-*   The `timestamp` attribute records the local date and time of the test
-    execution.
-
-*   Each `<failure>` element corresponds to a single failed googletest
-    assertion.
-
-#### Generating a JSON Report
-
-googletest can also emit a JSON report as an alternative format to XML. To
-generate the JSON report, set the `GTEST_OUTPUT` environment variable or the
-`--gtest_output` flag to the string `"json:path_to_output_file"`, which will
-create the file at the given location. You can also just use the string
-`"json"`, in which case the output can be found in the `test_detail.json` file
-in the current directory.
-
-The report format conforms to the following JSON Schema:
-
-```json
-{
-  "$schema": "http://json-schema.org/schema#",
-  "type": "object",
-  "definitions": {
-    "TestCase": {

-
-### Controlling How Failures Are Reported
-
-#### Turning Assertion Failures into Break-Points
-
-When running test programs under a debugger, it's very convenient if the
-debugger can catch an assertion failure and automatically drop into interactive
-mode. googletest's *break-on-failure* mode supports this behavior.
-
-To enable it, set the `GTEST_BREAK_ON_FAILURE` environment variable to a value
-other than `0`. Alternatively, you can use the `--gtest_break_on_failure`
-command line flag.
-
-#### Disabling Catching Test-Thrown Exceptions
-
-googletest can be used either with or without exceptions enabled. If a test
-throws a C++ exception or (on Windows) a structured exception (SEH), by default
-googletest catches it, reports it as a test failure, and continues with the next
-test method. This maximizes the coverage of a test run. Also, on Windows an
-uncaught exception will cause a pop-up window, so catching the exceptions allows
-you to run the tests automatically.
-
-When debugging the test failures, however, you may instead want the exceptions
-to be handled by the debugger, such that you can examine the call stack when an
-exception is thrown. To achieve that, set the `GTEST_CATCH_EXCEPTIONS`
-environment variable to `0`, or use the `--gtest_catch_exceptions=0` flag when
-running the tests.

-
-## Why should test suite names and test names not contain underscore?
-
-Underscore (`_`) is special, as C++ reserves the following to be used by the
-compiler and the standard library:
-
-1.  any identifier that starts with an `_` followed by an upper-case letter, and
-2.  any identifier that contains two consecutive underscores (i.e. `__`)
-    *anywhere* in its name.
-
-User code is *prohibited* from using such identifiers.
-
-Now let's look at what this means for `TEST` and `TEST_F`.
-
-Currently `TEST(TestSuiteName, TestName)` generates a class named
-`TestSuiteName_TestName_Test`. What happens if `TestSuiteName` or `TestName`
-contains `_`?
-
-1.  If `TestSuiteName` starts with an `_` followed by an upper-case letter (say,
-    `_Foo`), we end up with `_Foo_TestName_Test`, which is reserved and thus
-    invalid.
-2.  If `TestSuiteName` ends with an `_` (say, `Foo_`), we get
-    `Foo__TestName_Test`, which is invalid.
-3.  If `TestName` starts with an `_` (say, `_Bar`), we get
-    `TestSuiteName__Bar_Test`, which is invalid.
-4.  If `TestName` ends with an `_` (say, `Bar_`), we get
-    `TestSuiteName_Bar__Test`, which is invalid.
-
-So clearly `TestSuiteName` and `TestName` cannot start or end with `_`
-(Actually, `TestSuiteName` can start with `_` -- as long as the `_` isn't
-followed by an upper-case letter. But that's getting complicated. So for
-simplicity we just say that it cannot start with `_`.).
-
-It may seem fine for `TestSuiteName` and `TestName` to contain `_` in the
-middle. However, consider this:
-
-```c++
-TEST(Time, Flies_Like_An_Arrow) { ... }
-TEST(Time_Flies, Like_An_Arrow) { ... }
-```
-
-Now, the two `TEST`s will both generate the same class
-(`Time_Flies_Like_An_Arrow_Test`). That's not good.
-
-So for simplicity, we just ask the users to avoid `_` in `TestSuiteName` and
-`TestName`. The rule is more constraining than necessary, but it's simple and
-easy to remember. It also gives googletest some wiggle room in case its
-implementation needs to change in the future.
-
-If you violate the rule, there may not be immediate consequences, but your test
-may (just may) break with a new compiler (or a new version of the compiler you
-are using) or with a new version of googletest. Therefore it's best to follow
-the rule.
-
-## Why does googletest support `EXPECT_EQ(NULL, ptr)` and `ASSERT_EQ(NULL, ptr)` but not `EXPECT_NE(NULL, ptr)` and `ASSERT_NE(NULL, ptr)`?
-
-First of all you can use `EXPECT_NE(nullptr, ptr)` and `ASSERT_NE(nullptr,
-ptr)`. This is the preferred syntax in the style guide because nullptr does not
-have the type problems that NULL does. Which is why NULL does not work.
-
-Due to some peculiarity of C++, it requires some non-trivial template meta
-programming tricks to support using `NULL` as an argument of the `EXPECT_XX()`
-and `ASSERT_XX()` macros. Therefore we only do it where it's most needed
-(otherwise we make the implementation of googletest harder to maintain and more
-error-prone than necessary).
-
-The `EXPECT_EQ()` macro takes the *expected* value as its first argument and the
-*actual* value as the second. It's reasonable that someone wants to write
-`EXPECT_EQ(NULL, some_expression)`, and this indeed was requested several times.
-Therefore we implemented it.
-
-The need for `EXPECT_NE(NULL, ptr)` isn't nearly as strong. When the assertion
-fails, you already know that `ptr` must be `NULL`, so it doesn't add any
-information to print `ptr` in this case. That means `EXPECT_TRUE(ptr != NULL)`
-works just as well.
-
-If we were to support `EXPECT_NE(NULL, ptr)`, for consistency we'll have to
-support `EXPECT_NE(ptr, NULL)` as well, as unlike `EXPECT_EQ`, we don't have a
-convention on the order of the two arguments for `EXPECT_NE`. This means using
-the template meta programming tricks twice in the implementation, making it even
-harder to understand and maintain. We believe the benefit doesn't justify the
-cost.
-
-Finally, with the growth of the gMock matcher library, we are encouraging people
-to use the unified `EXPECT_THAT(value, matcher)` syntax more often in tests. One
-significant advantage of the matcher approach is that matchers can be easily
-combined to form new matchers, while the `EXPECT_NE`, etc, macros cannot be
-easily combined. Therefore we want to invest more in the matchers than in the
-`EXPECT_XX()` macros.
-
-## I need to test that different implementations of an interface satisfy some common requirements. Should I use typed tests or value-parameterized tests?

-For testing various implementations of the same interface, either typed tests or
-value-parameterized tests can get it done. It's really up to you the user to
-decide which is more convenient for you, depending on your particular case. Some
-rough guidelines:
-
-*   Typed tests can be easier to write if instances of the different
-    implementations can be created the same way, modulo the type. For example,
-    if all these implementations have a public default constructor (such that
-    you can write `new TypeParam`), or if their factory functions have the same
-    form (e.g. `CreateInstance<TypeParam>()`).
-*   Value-parameterized tests can be easier to write if you need different code
-    patterns to create different implementations' instances, e.g. `new Foo` vs
-    `new Bar(5)`. To accommodate for the differences, you can write factory
-    function wrappers and pass these function pointers to the tests as their
-    parameters.
-*   When a typed test fails, the default output includes the name of the type,
-    which can help you quickly identify which implementation is wrong.
-    Value-parameterized tests only show the number of the failed iteration by
-    default. You will need to define a function that returns the iteration name
-    and pass it as the third parameter to INSTANTIATE_TEST_SUITE_P to have more
-    useful output.
-*   When using typed tests, you need to make sure you are testing against the
-    interface type, not the concrete types (in other words, you want to make
-    sure `implicit_cast<MyInterface*>(my_concrete_impl)` works, not just that
-    `my_concrete_impl` works). It's less likely to make mistakes in this area
-    when using value-parameterized tests.
-
-I hope I didn't confuse you more. :-) If you don't mind, I'd suggest you to give
-both approaches a try. Practice is a much better way to grasp the subtle
-differences between the two tools. Once you have some concrete experience, you
-can much more easily decide which one to use the next time.

-## I got some run-time errors about invalid proto descriptors when using `ProtocolMessageEquals`. Help!
-
-**Note:** `ProtocolMessageEquals` and `ProtocolMessageEquiv` are *deprecated*
-now. Please use `EqualsProto`, etc instead.
-
-`ProtocolMessageEquals` and `ProtocolMessageEquiv` were redefined recently and
-are now less tolerant of invalid protocol buffer definitions. In particular, if
-you have a `foo.proto` that doesn't fully qualify the type of a protocol message
-it references (e.g. `message<Bar>` where it should be `message<blah.Bar>`), you
-will now get run-time errors like:
-
-```
-... descriptor.cc:...] Invalid proto descriptor for file "path/to/foo.proto":
-... descriptor.cc:...]  blah.MyMessage.my_field: ".Bar" is not defined.
-```
-
-If you see this, your `.proto` file is broken and needs to be fixed by making
-the types fully qualified. The new definition of `ProtocolMessageEquals` and
-`ProtocolMessageEquiv` just happen to reveal your bug.
-
-## My death test modifies some state, but the change seems lost after the death test finishes. Why?
-
-Death tests (`EXPECT_DEATH`, etc) are executed in a sub-process s.t. the
-expected crash won't kill the test program (i.e. the parent process). As a
-result, any in-memory side effects they incur are observable in their respective
-sub-processes, but not in the parent process. You can think of them as running
-in a parallel universe, more or less.
-
-In particular, if you use mocking and the death test statement invokes some mock
-methods, the parent process will think the calls have never occurred. Therefore,
-you may want to move your `EXPECT_CALL` statements inside the `EXPECT_DEATH`
-macro.
-
-## EXPECT_EQ(htonl(blah), blah_blah) generates weird compiler errors in opt mode. Is this a googletest bug?
-
-Actually, the bug is in `htonl()`.
-
-According to `'man htonl'`, `htonl()` is a *function*, which means it's valid to
-use `htonl` as a function pointer. However, in opt mode `htonl()` is defined as
-a *macro*, which breaks this usage.
-
-Worse, the macro definition of `htonl()` uses a `gcc` extension and is *not*
-standard C++. That hacky implementation has some ad hoc limitations. In
-particular, it prevents you from writing `Foo<sizeof(htonl(x))>()`, where `Foo`
-is a template that has an integral argument.
-
-The implementation of `EXPECT_EQ(a, b)` uses `sizeof(... a ...)` inside a
-template argument, and thus doesn't compile in opt mode when `a` contains a call
-to `htonl()`. It is difficult to make `EXPECT_EQ` bypass the `htonl()` bug, as
-the solution must work with different compilers on various platforms.
-
-`htonl()` has some other problems as described in `//util/endian/endian.h`,
-which defines `ghtonl()` to replace it. `ghtonl()` does the same thing `htonl()`
-does, only without its problems. We suggest you to use `ghtonl()` instead of
-`htonl()`, both in your tests and production code.
-
-`//util/endian/endian.h` also defines `ghtons()`, which solves similar problems
-in `htons()`.
-
-Don't forget to add `//util/endian` to the list of dependencies in the `BUILD`
-file wherever `ghtonl()` and `ghtons()` are used. The library consists of a
-single header file and will not bloat your binary.
-
-## The compiler complains about "undefined references" to some static const member variables, but I did define them in the class body. What's wrong?
-
-If your class has a static data member:
-
-```c++
-// foo.h
-class Foo {
-  ...
-  static const int kBar = 100;
-};
-```
-
-You also need to define it *outside* of the class body in `foo.cc`:
-
-```c++
-const int Foo::kBar;  // No initializer here.
-```
-
-Otherwise your code is **invalid C++**, and may break in unexpected ways. In
-particular, using it in googletest comparison assertions (`EXPECT_EQ`, etc) will
-generate an "undefined reference" linker error. The fact that "it used to work"
-doesn't mean it's valid. It just means that you were lucky. :-)
-
-## Can I derive a test fixture from another?
-
-Yes.
-
-Each test fixture has a corresponding and same named test suite. This means only
-one test suite can use a particular fixture. Sometimes, however, multiple test
-cases may want to use the same or slightly different fixtures. For example, you
-may want to make sure that all of a GUI library's test suites don't leak
-important system resources like fonts and brushes.
-
-In googletest, you share a fixture among test suites by putting the shared logic
-in a base test fixture, then deriving from that base a separate fixture for each
-test suite that wants to use this common logic. You then use `TEST_F()` to write
-tests using each derived fixture.
-
-Typically, your code looks like this:
-
-```c++
-// Defines a base test fixture.
-class BaseTest : public ::testing::Test {
- protected:
-  ...
-};
-
-// Derives a fixture FooTest from BaseTest.
-class FooTest : public BaseTest {
- protected:
-  void SetUp() override {
-    BaseTest::SetUp();  // Sets up the base fixture first.
-    ... additional set-up work ...
-  }
-
-  void TearDown() override {
-    ... clean-up work for FooTest ...
-    BaseTest::TearDown();  // Remember to tear down the base fixture
-                           // after cleaning up FooTest!
-  }
-
-  ... functions and variables for FooTest ...
-};
-
-// Tests that use the fixture FooTest.
-TEST_F(FooTest, Bar) { ... }
-TEST_F(FooTest, Baz) { ... }
-
-... additional fixtures derived from BaseTest ...
-```
-
-If necessary, you can continue to derive test fixtures from a derived fixture.
-googletest has no limit on how deep the hierarchy can be.
-
-For a complete example using derived test fixtures, see
-[sample5_unittest.cc](../samples/sample5_unittest.cc).
-
-## My compiler complains "void value not ignored as it ought to be." What does this mean?
-
-You're probably using an `ASSERT_*()` in a function that doesn't return `void`.
-`ASSERT_*()` can only be used in `void` functions, due to exceptions being
-disabled by our build system. Please see more details
-[here](advanced.md#assertion-placement).
-
-## My death test hangs (or seg-faults). How do I fix it?
-
-In googletest, death tests are run in a child process and the way they work is
-delicate. To write death tests you really need to understand how they work.
-Please make sure you have read [this](advanced.md#how-it-works).
-
-In particular, death tests don't like having multiple threads in the parent
-process. So the first thing you can try is to eliminate creating threads outside
-of `EXPECT_DEATH()`. For example, you may want to use mocks or fake objects
-instead of real ones in your tests.
-
-Sometimes this is impossible as some library you must use may be creating
-threads before `main()` is even reached. In this case, you can try to minimize
-the chance of conflicts by either moving as many activities as possible inside
-`EXPECT_DEATH()` (in the extreme case, you want to move everything inside), or
-leaving as few things as possible in it. Also, you can try to set the death test
-style to `"threadsafe"`, which is safer but slower, and see if it helps.
-
-If you go with thread-safe death tests, remember that they rerun the test
-program from the beginning in the child process. Therefore make sure your
-program can run side-by-side with itself and is deterministic.
-
-In the end, this boils down to good concurrent programming. You have to make
-sure that there is no race conditions or dead locks in your program. No silver
-bullet - sorry!
-
-## Should I use the constructor/destructor of the test fixture or SetUp()/TearDown()? {#CtorVsSetUp}
-
-The first thing to remember is that googletest does **not** reuse the same test
-fixture object across multiple tests. For each `TEST_F`, googletest will create
-a **fresh** test fixture object, immediately call `SetUp()`, run the test body,
-call `TearDown()`, and then delete the test fixture object.
-
-When you need to write per-test set-up and tear-down logic, you have the choice
-between using the test fixture constructor/destructor or `SetUp()/TearDown()`.
-The former is usually preferred, as it has the following benefits:
-
-*   By initializing a member variable in the constructor, we have the option to
-    make it `const`, which helps prevent accidental changes to its value and
-    makes the tests more obviously correct.
-*   In case we need to subclass the test fixture class, the subclass'
-    constructor is guaranteed to call the base class' constructor *first*, and
-    the subclass' destructor is guaranteed to call the base class' destructor
-    *afterward*. With `SetUp()/TearDown()`, a subclass may make the mistake of
-    forgetting to call the base class' `SetUp()/TearDown()` or call them at the
-    wrong time.
-
-You may still want to use `SetUp()/TearDown()` in the following cases:
-
-*   C++ does not allow virtual function calls in constructors and destructors.
-    You can call a method declared as virtual, but it will not use dynamic
-    dispatch, it will use the definition from the class the constructor of which
-    is currently executing. This is because calling a virtual method before the
-    derived class constructor has a chance to run is very dangerous - the
-    virtual method might operate on uninitialized data. Therefore, if you need
-    to call a method that will be overridden in a derived class, you have to use
-    `SetUp()/TearDown()`.
-*   In the body of a constructor (or destructor), it's not possible to use the
-    `ASSERT_xx` macros. Therefore, if the set-up operation could cause a fatal
-    test failure that should prevent the test from running, it's necessary to
-    use `abort` <!-- GOOGLETEST_CM0015 DO NOT DELETE --> and abort the whole test executable,
-    or to use `SetUp()` instead of a constructor.
-*   If the tear-down operation could throw an exception, you must use
-    `TearDown()` as opposed to the destructor, as throwing in a destructor leads
-    to undefined behavior and usually will kill your program right away. Note
-    that many standard libraries (like STL) may throw when exceptions are
-    enabled in the compiler. Therefore you should prefer `TearDown()` if you
-    want to write portable tests that work with or without exceptions.
-*   The googletest team is considering making the assertion macros throw on
-    platforms where exceptions are enabled (e.g. Windows, Mac OS, and Linux
-    client-side), which will eliminate the need for the user to propagate
-    failures from a subroutine to its caller. Therefore, you shouldn't use
-    googletest assertions in a destructor if your code could run on such a
-    platform.
-
-## The compiler complains "no matching function to call" when I use ASSERT_PRED*. How do I fix it?
-
-If the predicate function you use in `ASSERT_PRED*` or `EXPECT_PRED*` is
-overloaded or a template, the compiler will have trouble figuring out which
-overloaded version it should use. `ASSERT_PRED_FORMAT*` and
-`EXPECT_PRED_FORMAT*` don't have this problem.
-
-If you see this error, you might want to switch to
-`(ASSERT|EXPECT)_PRED_FORMAT*`, which will also give you a better failure
-message. If, however, that is not an option, you can resolve the problem by
-explicitly telling the compiler which version to pick.
-
-For example, suppose you have
-
-```c++
-bool IsPositive(int n) {
-  return n > 0;
-}
-
-bool IsPositive(double x) {
-  return x > 0;
-}
-```
-
-you will get a compiler error if you write
-
-```c++
-EXPECT_PRED1(IsPositive, 5);
-```
-
-However, this will work:
-
-```c++
-EXPECT_PRED1(static_cast<bool (*)(int)>(IsPositive), 5);
-```
-
-(The stuff inside the angled brackets for the `static_cast` operator is the type
-of the function pointer for the `int`-version of `IsPositive()`.)
-
-As another example, when you have a template function
-
-```c++
-template <typename T>
-bool IsNegative(T x) {
-  return x < 0;
-}
-```
-
-you can use it in a predicate assertion like this:
-
-```c++
-ASSERT_PRED1(IsNegative<int>, -5);
-```
-
-Things are more interesting if your template has more than one parameters. The
-following won't compile:
-
-```c++
-ASSERT_PRED2(GreaterThan<int, int>, 5, 0);
-```
-
-as the C++ pre-processor thinks you are giving `ASSERT_PRED2` 4 arguments, which
-is one more than expected. The workaround is to wrap the predicate function in
-parentheses:
-
-```c++
-ASSERT_PRED2((GreaterThan<int, int>), 5, 0);
-```
-
-## My compiler complains about "ignoring return value" when I call RUN_ALL_TESTS(). Why?
-
-Some people had been ignoring the return value of `RUN_ALL_TESTS()`. That is,
-instead of
-
-```c++
-  return RUN_ALL_TESTS();
-```
-
-they write
-
-```c++
-  RUN_ALL_TESTS();
-```
-
-This is **wrong and dangerous**. The testing services needs to see the return
-value of `RUN_ALL_TESTS()` in order to determine if a test has passed. If your
-`main()` function ignores it, your test will be considered successful even if it
-has a googletest assertion failure. Very bad.
-
-We have decided to fix this (thanks to Michael Chastain for the idea). Now, your
-code will no longer be able to ignore `RUN_ALL_TESTS()` when compiled with
-`gcc`. If you do so, you'll get a compiler error.
-
-If you see the compiler complaining about you ignoring the return value of
-`RUN_ALL_TESTS()`, the fix is simple: just make sure its value is used as the
-return value of `main()`.
-
-But how could we introduce a change that breaks existing tests? Well, in this
-case, the code was already broken in the first place, so we didn't break it. :-)
-
-## My compiler complains that a constructor (or destructor) cannot return a value. What's going on?
-
-Due to a peculiarity of C++, in order to support the syntax for streaming
-messages to an `ASSERT_*`, e.g.
-
-```c++
-  ASSERT_EQ(1, Foo()) << "blah blah" << foo;
-```
-
-we had to give up using `ASSERT*` and `FAIL*` (but not `EXPECT*` and
-`ADD_FAILURE*`) in constructors and destructors. The workaround is to move the
-content of your constructor/destructor to a private void member function, or
-switch to `EXPECT_*()` if that works. This
-[section](advanced.md#assertion-placement) in the user's guide explains it.
-
-## My SetUp() function is not called. Why?
-
-C++ is case-sensitive. Did you spell it as `Setup()`?
-
-Similarly, sometimes people spell `SetUpTestSuite()` as `SetupTestSuite()` and
-wonder why it's never called.
-
-
-## I have several test suites which share the same test fixture logic, do I have to define a new test fixture class for each of them? This seems pretty tedious.
-
-You don't have to. Instead of
-
-```c++
-class FooTest : public BaseTest {};
-
-TEST_F(FooTest, Abc) { ... }
-TEST_F(FooTest, Def) { ... }
-
-class BarTest : public BaseTest {};
-
-TEST_F(BarTest, Abc) { ... }
-TEST_F(BarTest, Def) { ... }
-```
-
-you can simply `typedef` the test fixtures:
-
-```c++
-typedef BaseTest FooTest;
-
-TEST_F(FooTest, Abc) { ... }
-TEST_F(FooTest, Def) { ... }
-
-typedef BaseTest BarTest;
-
-TEST_F(BarTest, Abc) { ... }
-TEST_F(BarTest, Def) { ... }
-```
-
-## googletest output is buried in a whole bunch of LOG messages. What do I do?
-
-The googletest output is meant to be a concise and human-friendly report. If
-your test generates textual output itself, it will mix with the googletest
-output, making it hard to read. However, there is an easy solution to this
-problem.
-
-Since `LOG` messages go to stderr, we decided to let googletest output go to
-stdout. This way, you can easily separate the two using redirection. For
-example:
-
-```shell
-$ ./my_test > gtest_output.txt
-```
-
-## Why should I prefer test fixtures over global variables?
-
-There are several good reasons:
-
-1.  It's likely your test needs to change the states of its global variables.
-    This makes it difficult to keep side effects from escaping one test and
-    contaminating others, making debugging difficult. By using fixtures, each
-    test has a fresh set of variables that's different (but with the same
-    names). Thus, tests are kept independent of each other.
-2.  Global variables pollute the global namespace.
-3.  Test fixtures can be reused via subclassing, which cannot be done easily
-    with global variables. This is useful if many test suites have something in
-    common.
-
-## What can the statement argument in ASSERT_DEATH() be?
-
-`ASSERT_DEATH(*statement*, *regex*)` (or any death assertion macro) can be used
-wherever `*statement*` is valid. So basically `*statement*` can be any C++
-statement that makes sense in the current context. In particular, it can
-reference global and/or local variables, and can be:
-
-*   a simple function call (often the case),
-*   a complex expression, or
-*   a compound statement.
-
-Some examples are shown here:
-
-```c++
-// A death test can be a simple function call.
-TEST(MyDeathTest, FunctionCall) {
-  ASSERT_DEATH(Xyz(5), "Xyz failed");
-}
-
-// Or a complex expression that references variables and functions.
-TEST(MyDeathTest, ComplexExpression) {
-  const bool c = Condition();
-  ASSERT_DEATH((c ? Func1(0) : object2.Method("test")),
-               "(Func1|Method) failed");
-}
-
-// Death assertions can be used any where in a function.  In
-// particular, they can be inside a loop.
-TEST(MyDeathTest, InsideLoop) {
-  // Verifies that Foo(0), Foo(1), ..., and Foo(4) all die.
-  for (int i = 0; i < 5; i++) {
-    EXPECT_DEATH_M(Foo(i), "Foo has \\d+ errors",
-                   ::testing::Message() << "where i is " << i);
-  }
-}
-
-// A death assertion can contain a compound statement.
-TEST(MyDeathTest, CompoundStatement) {
-  // Verifies that at lease one of Bar(0), Bar(1), ..., and
-  // Bar(4) dies.
-  ASSERT_DEATH({
-    for (int i = 0; i < 5; i++) {
-      Bar(i);
-    }
-  },
-  "Bar has \\d+ errors");
-}
-```
-
-gtest-death-test_test.cc contains more examples if you are interested.
-
-## I have a fixture class `FooTest`, but `TEST_F(FooTest, Bar)` gives me error ``"no matching function for call to `FooTest::FooTest()'"``. Why?
-
-Googletest needs to be able to create objects of your test fixture class, so it
-must have a default constructor. Normally the compiler will define one for you.
-However, there are cases where you have to define your own:
-
-*   If you explicitly declare a non-default constructor for class `FooTest`
-    (`DISALLOW_EVIL_CONSTRUCTORS()` does this), then you need to define a
-    default constructor, even if it would be empty.
-*   If `FooTest` has a const non-static data member, then you have to define the
-    default constructor *and* initialize the const member in the initializer
-    list of the constructor. (Early versions of `gcc` doesn't force you to
-    initialize the const member. It's a bug that has been fixed in `gcc 4`.)
-
-## Why does ASSERT_DEATH complain about previous threads that were already joined?
-
-With the Linux pthread library, there is no turning back once you cross the line
-from single thread to multiple threads. The first time you create a thread, a
-manager thread is created in addition, so you get 3, not 2, threads. Later when
-the thread you create joins the main thread, the thread count decrements by 1,
-but the manager thread will never be killed, so you still have 2 threads, which
-means you cannot safely run a death test.
-
-The new NPTL thread library doesn't suffer from this problem, as it doesn't
-create a manager thread. However, if you don't control which machine your test
-runs on, you shouldn't depend on this.
-
-## Why does googletest require the entire test suite, instead of individual tests, to be named *DeathTest when it uses ASSERT_DEATH?
-
-googletest does not interleave tests from different test suites. That is, it
-runs all tests in one test suite first, and then runs all tests in the next test
-suite, and so on. googletest does this because it needs to set up a test suite
-before the first test in it is run, and tear it down afterwords. Splitting up
-the test case would require multiple set-up and tear-down processes, which is
-inefficient and makes the semantics unclean.
-
-If we were to determine the order of tests based on test name instead of test
-case name, then we would have a problem with the following situation:
-
-```c++
-TEST_F(FooTest, AbcDeathTest) { ... }
-TEST_F(FooTest, Uvw) { ... }
-
-TEST_F(BarTest, DefDeathTest) { ... }
-TEST_F(BarTest, Xyz) { ... }
-```
-
-Since `FooTest.AbcDeathTest` needs to run before `BarTest.Xyz`, and we don't
-interleave tests from different test suites, we need to run all tests in the
-`FooTest` case before running any test in the `BarTest` case. This contradicts
-with the requirement to run `BarTest.DefDeathTest` before `FooTest.Uvw`.
-
-## But I don't like calling my entire test suite \*DeathTest when it contains both death tests and non-death tests. What do I do?
-
-You don't have to, but if you like, you may split up the test suite into
-`FooTest` and `FooDeathTest`, where the names make it clear that they are
-related:
-
-```c++
-class FooTest : public ::testing::Test { ... };
-
-TEST_F(FooTest, Abc) { ... }
-TEST_F(FooTest, Def) { ... }
-
-using FooDeathTest = FooTest;
-
-TEST_F(FooDeathTest, Uvw) { ... EXPECT_DEATH(...) ... }
-TEST_F(FooDeathTest, Xyz) { ... ASSERT_DEATH(...) ... }
-```
-
-## googletest prints the LOG messages in a death test's child process only when the test fails. How can I see the LOG messages when the death test succeeds?
-
-Printing the LOG messages generated by the statement inside `EXPECT_DEATH()`
-makes it harder to search for real problems in the parent's log. Therefore,
-googletest only prints them when the death test has failed.
-
-If you really need to see such LOG messages, a workaround is to temporarily
-break the death test (e.g. by changing the regex pattern it is expected to
-match). Admittedly, this is a hack. We'll consider a more permanent solution
-after the fork-and-exec-style death tests are implemented.
-
-## The compiler complains about "no match for 'operator<<'" when I use an assertion. What gives?
-
-If you use a user-defined type `FooType` in an assertion, you must make sure
-there is an `std::ostream& operator<<(std::ostream&, const FooType&)` function
-defined such that we can print a value of `FooType`.
-
-In addition, if `FooType` is declared in a name space, the `<<` operator also
-needs to be defined in the *same* name space. See https://abseil.io/tips/49 for details.
-
-## How do I suppress the memory leak messages on Windows?
-
-Since the statically initialized googletest singleton requires allocations on
-the heap, the Visual C++ memory leak detector will report memory leaks at the
-end of the program run. The easiest way to avoid this is to use the
-`_CrtMemCheckpoint` and `_CrtMemDumpAllObjectsSince` calls to not report any
-statically initialized heap objects. See MSDN for more details and additional
-heap check/debug routines.
-
-## How can my code detect if it is running in a test?
-
-If you write code that sniffs whether it's running in a test and does different
-things accordingly, you are leaking test-only logic into production code and
-there is no easy way to ensure that the test-only code paths aren't run by
-mistake in production. Such cleverness also leads to
-[Heisenbugs](https://en.wikipedia.org/wiki/Heisenbug). Therefore we strongly
-advise against the practice, and googletest doesn't provide a way to do it.
-
-In general, the recommended way to cause the code to behave differently under
-test is [Dependency Injection](https://en.wikipedia.org/wiki/Dependency_injection). You can inject
-different functionality from the test and from the production code. Since your
-production code doesn't link in the for-test logic at all (the
-[`testonly`](https://docs.bazel.build/versions/master/be/common-definitions.html#common.testonly) attribute for BUILD targets helps to ensure
-that), there is no danger in accidentally running it.
-
-However, if you *really*, *really*, *really* have no choice, and if you follow
-the rule of ending your test program names with `_test`, you can use the
-*horrible* hack of sniffing your executable name (`argv[0]` in `main()`) to know
-whether the code is under test.
-
-## How do I temporarily disable a test?
-
-If you have a broken test that you cannot fix right away, you can add the
-DISABLED_ prefix to its name. This will exclude it from execution. This is
-better than commenting out the code or using #if 0, as disabled tests are still
-compiled (and thus won't rot).
-
-To include disabled tests in test execution, just invoke the test program with
-the --gtest_also_run_disabled_tests flag.
-
-## Is it OK if I have two separate `TEST(Foo, Bar)` test methods defined in different namespaces?
-
-Yes.
-
-The rule is **all test methods in the same test suite must use the same fixture
-class.** This means that the following is **allowed** because both tests use the
-same fixture class (`::testing::Test`).
-
-```c++
-namespace foo {
-TEST(CoolTest, DoSomething) {
-  SUCCEED();
-}
-}  // namespace foo
-
-namespace bar {
-TEST(CoolTest, DoSomething) {
-  SUCCEED();
-}
-}  // namespace bar
-```
-
-However, the following code is **not allowed** and will produce a runtime error
-from googletest because the test methods are using different test fixture
-classes with the same test suite name.
-
-```c++
-namespace foo {
-class CoolTest : public ::testing::Test {};  // Fixture foo::CoolTest
-TEST_F(CoolTest, DoSomething) {
-  SUCCEED();
-}
-}  // namespace foo
-
-namespace bar {
-class CoolTest : public ::testing::Test {};  // Fixture: bar::CoolTest
-TEST_F(CoolTest, DoSomething) {
-  SUCCEED();
-}
-}  // namespace bar
-```

-## Using GoogleTest from various build systems
-
-GoogleTest comes with pkg-config files that can be used to determine all
-necessary flags for compiling and linking to GoogleTest (and GoogleMock).
-Pkg-config is a standardised plain-text format containing
-
-*   the includedir (-I) path
-*   necessary macro (-D) definitions
-*   further required flags (-pthread)
-*   the library (-L) path
-*   the library (-l) to link to
-
-All current build systems support pkg-config in one way or another. For all
-examples here we assume you want to compile the sample
-`samples/sample3_unittest.cc`.
-
-### CMake
-
-Using `pkg-config` in CMake is fairly easy:
-
-```cmake
-cmake_minimum_required(VERSION 3.0)
-
-cmake_policy(SET CMP0048 NEW)
-project(my_gtest_pkgconfig VERSION 0.0.1 LANGUAGES CXX)
-
-find_package(PkgConfig)
-pkg_search_module(GTEST REQUIRED gtest_main)
-
-add_executable(testapp samples/sample3_unittest.cc)
-target_link_libraries(testapp ${GTEST_LDFLAGS})
-target_compile_options(testapp PUBLIC ${GTEST_CFLAGS})
-
-include(CTest)
-add_test(first_and_only_test testapp)
-```
-
-It is generally recommended that you use `target_compile_options` + `_CFLAGS`
-over `target_include_directories` + `_INCLUDE_DIRS` as the former includes not
-just -I flags (GoogleTest might require a macro indicating to internal headers
-that all libraries have been compiled with threading enabled. In addition,
-GoogleTest might also require `-pthread` in the compiling step, and as such
-splitting the pkg-config `Cflags` variable into include dirs and macros for
-`target_compile_definitions()` might still miss this). The same recommendation
-goes for using `_LDFLAGS` over the more commonplace `_LIBRARIES`, which happens
-to discard `-L` flags and `-pthread`.
-
-### Autotools
-
-Finding GoogleTest in Autoconf and using it from Automake is also fairly easy:
-
-In your `configure.ac`:
-
-```
-AC_PREREQ([2.69])
-AC_INIT([my_gtest_pkgconfig], [0.0.1])
-AC_CONFIG_SRCDIR([samples/sample3_unittest.cc])
-AC_PROG_CXX
-
-PKG_CHECK_MODULES([GTEST], [gtest_main])
-
-AM_INIT_AUTOMAKE([foreign subdir-objects])
-AC_CONFIG_FILES([Makefile])
-AC_OUTPUT
-```
-
-and in your `Makefile.am`:
-
-```
-check_PROGRAMS = testapp
-TESTS = $(check_PROGRAMS)
-
-testapp_SOURCES = samples/sample3_unittest.cc
-testapp_CXXFLAGS = $(GTEST_CFLAGS)
-testapp_LDADD = $(GTEST_LIBS)
-```
-
-### Meson
-
-Meson natively uses pkgconfig to query dependencies:
-
-```
-project('my_gtest_pkgconfig', 'cpp', version : '0.0.1')
-
-gtest_dep = dependency('gtest_main')
-
-testapp = executable(
-  'testapp',
-  files(['samples/sample3_unittest.cc']),
-  dependencies : gtest_dep,
-  install : false)
-
-test('first_and_only_test', testapp)
-```
-
-### Plain Makefiles
-
-Since `pkg-config` is a small Unix command-line utility, it can be used in
-handwritten `Makefile`s too:
-
-```makefile
-GTEST_CFLAGS = `pkg-config --cflags gtest_main`
-GTEST_LIBS = `pkg-config --libs gtest_main`
-
-.PHONY: tests all
-
-tests: all
-  ./testapp
-
-all: testapp
-
-testapp: testapp.o
-  $(CXX) $(CXXFLAGS) $(LDFLAGS) $< -o $@ $(GTEST_LIBS)
-
-testapp.o: samples/sample3_unittest.cc
-  $(CXX) $(CPPFLAGS) $(CXXFLAGS) $< -c -o $@ $(GTEST_CFLAGS)
-```
-
-### Help! pkg-config can't find GoogleTest!
-
-Let's say you have a `CMakeLists.txt` along the lines of the one in this
-tutorial and you try to run `cmake`. It is very possible that you get a failure
-along the lines of:
-
-```
--- Checking for one of the modules 'gtest_main'
-CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:640 (message):
-  None of the required 'gtest_main' found
-```
-
-These failures are common if you installed GoogleTest yourself and have not
-sourced it from a distro or other package manager. If so, you need to tell
-pkg-config where it can find the `.pc` files containing the information. Say you
-installed GoogleTest to `/usr/local`, then it might be that the `.pc` files are
-installed under `/usr/local/lib64/pkgconfig`. If you set
-
-```
-export PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig
-```
-
-pkg-config will also try to look in `PKG_CONFIG_PATH` to find `gtest_main.pc`.

-# Googletest Primer
-
-## Introduction: Why googletest?
-
-*googletest* helps you write better C++ tests.
-
-googletest is a testing framework developed by the Testing Technology team with
-Google's specific requirements and constraints in mind. Whether you work on
-Linux, Windows, or a Mac, if you write C++ code, googletest can help you. And it
-supports *any* kind of tests, not just unit tests.
-
-So what makes a good test, and how does googletest fit in? We believe:
-
-1.  Tests should be *independent* and *repeatable*. It's a pain to debug a test
-    that succeeds or fails as a result of other tests. googletest isolates the
-    tests by running each of them on a different object. When a test fails,
-    googletest allows you to run it in isolation for quick debugging.
-2.  Tests should be well *organized* and reflect the structure of the tested
-    code. googletest groups related tests into test suites that can share data
-    and subroutines. This common pattern is easy to recognize and makes tests
-    easy to maintain. Such consistency is especially helpful when people switch
-    projects and start to work on a new code base.
-3.  Tests should be *portable* and *reusable*. Google has a lot of code that is
-    platform-neutral; its tests should also be platform-neutral. googletest
-    works on different OSes, with different compilers, with or without
-    exceptions, so googletest tests can work with a variety of configurations.
-4.  When tests fail, they should provide as much *information* about the problem
-    as possible. googletest doesn't stop at the first test failure. Instead, it
-    only stops the current test and continues with the next. You can also set up
-    tests that report non-fatal failures after which the current test continues.
-    Thus, you can detect and fix multiple bugs in a single run-edit-compile
-    cycle.
-5.  The testing framework should liberate test writers from housekeeping chores
-    and let them focus on the test *content*. googletest automatically keeps
-    track of all tests defined, and doesn't require the user to enumerate them
-    in order to run them.
-6.  Tests should be *fast*. With googletest, you can reuse shared resources
-    across tests and pay for the set-up/tear-down only once, without making
-    tests depend on each other.
-
-Since googletest is based on the popular xUnit architecture, you'll feel right
-at home if you've used JUnit or PyUnit before. If not, it will take you about 10
-minutes to learn the basics and get started. So let's go!
-
-## Beware of the nomenclature
-
-_Note:_ There might be some confusion arising from different definitions of the
-terms _Test_, _Test Case_ and _Test Suite_, so beware of misunderstanding these.
-
-Historically, googletest started to use the term _Test Case_ for grouping
-related tests, whereas current publications, including International Software
-Testing Qualifications Board ([ISTQB](http://www.istqb.org/)) materials and
-various textbooks on software quality, use the term
-_[Test Suite][istqb test suite]_ for this.
-
-The related term _Test_, as it is used in googletest, corresponds to the term
-_[Test Case][istqb test case]_ of ISTQB and others.
-
-The term _Test_ is commonly of broad enough sense, including ISTQB's definition
-of _Test Case_, so it's not much of a problem here. But the term _Test Case_ as
-was used in Google Test is of contradictory sense and thus confusing.
-
-googletest recently started replacing the term _Test Case_ with _Test Suite_.
-The preferred API is *TestSuite*. The older TestCase API is being slowly
-deprecated and refactored away.
-
-So please be aware of the different definitions of the terms:

-
-## Basic Concepts
-
-When using googletest, you start by writing *assertions*, which are statements
-that check whether a condition is true. An assertion's result can be *success*,
-*nonfatal failure*, or *fatal failure*. If a fatal failure occurs, it aborts the
-current function; otherwise the program continues normally.
-
-*Tests* use assertions to verify the tested code's behavior. If a test crashes
-or has a failed assertion, then it *fails*; otherwise it *succeeds*.
-
-A *test suite* contains one or many tests. You should group your tests into test
-suites that reflect the structure of the tested code. When multiple tests in a
-test suite need to share common objects and subroutines, you can put them into a
-*test fixture* class.
-
-A *test program* can contain multiple test suites.
-
-We'll now explain how to write a test program, starting at the individual
-assertion level and building up to tests and test suites.
-
-## Assertions
-
-googletest assertions are macros that resemble function calls. You test a class
-or function by making assertions about its behavior. When an assertion fails,
-googletest prints the assertion's source file and line number location, along
-with a failure message. You may also supply a custom failure message which will
-be appended to googletest's message.
-
-The assertions come in pairs that test the same thing but have different effects
-on the current function. `ASSERT_*` versions generate fatal failures when they
-fail, and **abort the current function**. `EXPECT_*` versions generate nonfatal
-failures, which don't abort the current function. Usually `EXPECT_*` are
-preferred, as they allow more than one failure to be reported in a test.
-However, you should use `ASSERT_*` if it doesn't make sense to continue when the
-assertion in question fails.
-
-Since a failed `ASSERT_*` returns from the current function immediately,
-possibly skipping clean-up code that comes after it, it may cause a space leak.
-Depending on the nature of the leak, it may or may not be worth fixing - so keep
-this in mind if you get a heap checker error in addition to assertion errors.
-
-To provide a custom failure message, simply stream it into the macro using the
-`<<` operator or a sequence of such operators. An example:
-
-```c++
-ASSERT_EQ(x.size(), y.size()) << "Vectors x and y are of unequal length";
-
-for (int i = 0; i < x.size(); ++i) {
-  EXPECT_EQ(x[i], y[i]) << "Vectors x and y differ at index " << i;
-}
-```
-
-Anything that can be streamed to an `ostream` can be streamed to an assertion
-macro--in particular, C strings and `string` objects. If a wide string
-(`wchar_t*`, `TCHAR*` in `UNICODE` mode on Windows, or `std::wstring`) is
-streamed to an assertion, it will be translated to UTF-8 when printed.
-
-### Basic Assertions
-
-These assertions do basic true/false condition testing.
-
-Fatal assertion            | Nonfatal assertion         | Verifies
--------------------------- | -------------------------- | --------------------
-`ASSERT_TRUE(condition);`  | `EXPECT_TRUE(condition);`  | `condition` is true
-`ASSERT_FALSE(condition);` | `EXPECT_FALSE(condition);` | `condition` is false
-
-Remember, when they fail, `ASSERT_*` yields a fatal failure and returns from the
-current function, while `EXPECT_*` yields a nonfatal failure, allowing the
-function to continue running. In either case, an assertion failure means its
-containing test fails.
-
-**Availability**: Linux, Windows, Mac.
-
-### Binary Comparison
-
-This section describes assertions that compare two values.
-
-Fatal assertion          | Nonfatal assertion       | Verifies
------------------------- | ------------------------ | --------------
-`ASSERT_EQ(val1, val2);` | `EXPECT_EQ(val1, val2);` | `val1 == val2`
-`ASSERT_NE(val1, val2);` | `EXPECT_NE(val1, val2);` | `val1 != val2`
-`ASSERT_LT(val1, val2);` | `EXPECT_LT(val1, val2);` | `val1 < val2`
-`ASSERT_LE(val1, val2);` | `EXPECT_LE(val1, val2);` | `val1 <= val2`
-`ASSERT_GT(val1, val2);` | `EXPECT_GT(val1, val2);` | `val1 > val2`
-`ASSERT_GE(val1, val2);` | `EXPECT_GE(val1, val2);` | `val1 >= val2`
-
-Value arguments must be comparable by the assertion's comparison operator or
-you'll get a compiler error. We used to require the arguments to support the
-`<<` operator for streaming to an `ostream`, but this is no longer necessary. If
-`<<` is supported, it will be called to print the arguments when the assertion
-fails; otherwise googletest will attempt to print them in the best way it can.
-For more details and how to customize the printing of the arguments, see the
-[documentation](../../googlemock/docs/cook_book.md#teaching-gmock-how-to-print-your-values).
-
-These assertions can work with a user-defined type, but only if you define the
-corresponding comparison operator (e.g., `==` or `<`). Since this is discouraged
-by the Google
-[C++ Style Guide](https://google.github.io/styleguide/cppguide.html#Operator_Overloading),
-you may need to use `ASSERT_TRUE()` or `EXPECT_TRUE()` to assert the equality of
-two objects of a user-defined type.
-
-However, when possible, `ASSERT_EQ(actual, expected)` is preferred to
-`ASSERT_TRUE(actual == expected)`, since it tells you `actual` and `expected`'s
-values on failure.
-
-Arguments are always evaluated exactly once. Therefore, it's OK for the
-arguments to have side effects. However, as with any ordinary C/C++ function,
-the arguments' evaluation order is undefined (i.e., the compiler is free to
-choose any order), and your code should not depend on any particular argument
-evaluation order.
-
-`ASSERT_EQ()` does pointer equality on pointers. If used on two C strings, it
-tests if they are in the same memory location, not if they have the same value.
-Therefore, if you want to compare C strings (e.g. `const char*`) by value, use
-`ASSERT_STREQ()`, which will be described later on. In particular, to assert
-that a C string is `NULL`, use `ASSERT_STREQ(c_string, NULL)`. Consider using
-`ASSERT_EQ(c_string, nullptr)` if c++11 is supported. To compare two `string`
-objects, you should use `ASSERT_EQ`.
-
-When doing pointer comparisons use `*_EQ(ptr, nullptr)` and `*_NE(ptr, nullptr)`
-instead of `*_EQ(ptr, NULL)` and `*_NE(ptr, NULL)`. This is because `nullptr` is
-typed, while `NULL` is not. See the [FAQ](faq.md) for more details.
-
-If you're working with floating point numbers, you may want to use the floating
-point variations of some of these macros in order to avoid problems caused by
-rounding. See [Advanced googletest Topics](advanced.md) for details.
-
-Macros in this section work with both narrow and wide string objects (`string`
-and `wstring`).
-
-**Availability**: Linux, Windows, Mac.
-
-**Historical note**: Before February 2016 `*_EQ` had a convention of calling it
-as `ASSERT_EQ(expected, actual)`, so lots of existing code uses this order. Now
-`*_EQ` treats both parameters in the same way.
-
-### String Comparison
-
-The assertions in this group compare two **C strings**. If you want to compare
-two `string` objects, use `EXPECT_EQ`, `EXPECT_NE`, and etc instead.
-
-<!-- mdformat off(github rendering does not support multiline tables) -->
-
-| Fatal assertion                | Nonfatal assertion             | Verifies                                                 |
-| --------------------------     | ------------------------------ | -------------------------------------------------------- |
-| `ASSERT_STREQ(str1,str2);`     | `EXPECT_STREQ(str1,str2);`     | the two C strings have the same content   		     |
-| `ASSERT_STRNE(str1,str2);`     | `EXPECT_STRNE(str1,str2);`     | the two C strings have different contents 		     |
-| `ASSERT_STRCASEEQ(str1,str2);` | `EXPECT_STRCASEEQ(str1,str2);` | the two C strings have the same content, ignoring case   |
-| `ASSERT_STRCASENE(str1,str2);` | `EXPECT_STRCASENE(str1,str2);` | the two C strings have different contents, ignoring case |
-
-<!-- mdformat on-->
-
-Note that "CASE" in an assertion name means that case is ignored. A `NULL`
-pointer and an empty string are considered *different*.
-
-`*STREQ*` and `*STRNE*` also accept wide C strings (`wchar_t*`). If a comparison
-of two wide strings fails, their values will be printed as UTF-8 narrow strings.
-
-**Availability**: Linux, Windows, Mac.
-
-**See also**: For more string comparison tricks (substring, prefix, suffix, and
-regular expression matching, for example), see [this](advanced.md) in the
-Advanced googletest Guide.
-
-## Simple Tests
-
-To create a test:
-
-1.  Use the `TEST()` macro to define and name a test function. These are
-    ordinary C++ functions that don't return a value.
-2.  In this function, along with any valid C++ statements you want to include,
-    use the various googletest assertions to check values.
-3.  The test's result is determined by the assertions; if any assertion in the
-    test fails (either fatally or non-fatally), or if the test crashes, the
-    entire test fails. Otherwise, it succeeds.
-
-```c++
-TEST(TestSuiteName, TestName) {
-  ... test body ...
-}
-```
-
-`TEST()` arguments go from general to specific. The *first* argument is the name
-of the test suite, and the *second* argument is the test's name within the test
-case. Both names must be valid C++ identifiers, and they should not contain
-any underscores (`_`). A test's *full name* consists of its containing test suite and
-its individual name. Tests from different test suites can have the same
-individual name.
-
-For example, let's take a simple integer function:
-
-```c++
-int Factorial(int n);  // Returns the factorial of n
-```
-
-A test suite for this function might look like:
-
-```c++
-// Tests factorial of 0.
-TEST(FactorialTest, HandlesZeroInput) {
-  EXPECT_EQ(Factorial(0), 1);
-}
-
-// Tests factorial of positive numbers.
-TEST(FactorialTest, HandlesPositiveInput) {
-  EXPECT_EQ(Factorial(1), 1);
-  EXPECT_EQ(Factorial(2), 2);
-  EXPECT_EQ(Factorial(3), 6);
-  EXPECT_EQ(Factorial(8), 40320);
-}
-```
-
-googletest groups the test results by test suites, so logically related tests
-should be in the same test suite; in other words, the first argument to their
-`TEST()` should be the same. In the above example, we have two tests,
-`HandlesZeroInput` and `HandlesPositiveInput`, that belong to the same test
-suite `FactorialTest`.
-
-When naming your test suites and tests, you should follow the same convention as
-for
-[naming functions and classes](https://google.github.io/styleguide/cppguide.html#Function_Names).
-
-**Availability**: Linux, Windows, Mac.
-
-## Test Fixtures: Using the Same Data Configuration for Multiple Tests {#same-data-multiple-tests}
-
-If you find yourself writing two or more tests that operate on similar data, you
-can use a *test fixture*. This allows you to reuse the same configuration of
-objects for several different tests.
-
-To create a fixture:
-
-1.  Derive a class from `::testing::Test` . Start its body with `protected:`, as
-    we'll want to access fixture members from sub-classes.
-2.  Inside the class, declare any objects you plan to use.
-3.  If necessary, write a default constructor or `SetUp()` function to prepare
-    the objects for each test. A common mistake is to spell `SetUp()` as
-    **`Setup()`** with a small `u` - Use `override` in C++11 to make sure you
-    spelled it correctly.
-4.  If necessary, write a destructor or `TearDown()` function to release any
-    resources you allocated in `SetUp()` . To learn when you should use the
-    constructor/destructor and when you should use `SetUp()/TearDown()`, read
-    the [FAQ](faq.md#CtorVsSetUp).
-5.  If needed, define subroutines for your tests to share.
-
-When using a fixture, use `TEST_F()` instead of `TEST()` as it allows you to
-access objects and subroutines in the test fixture:
-
-```c++
-TEST_F(TestFixtureName, TestName) {
-  ... test body ...
-}
-```
-
-Like `TEST()`, the first argument is the test suite name, but for `TEST_F()`
-this must be the name of the test fixture class. You've probably guessed: `_F`
-is for fixture.
-
-Unfortunately, the C++ macro system does not allow us to create a single macro
-that can handle both types of tests. Using the wrong macro causes a compiler
-error.
-
-Also, you must first define a test fixture class before using it in a
-`TEST_F()`, or you'll get the compiler error "`virtual outside class
-declaration`".
-
-For each test defined with `TEST_F()`, googletest will create a *fresh* test
-fixture at runtime, immediately initialize it via `SetUp()`, run the test,
-clean up by calling `TearDown()`, and then delete the test fixture. Note that
-different tests in the same test suite have different test fixture objects, and
-googletest always deletes a test fixture before it creates the next one.
-googletest does **not** reuse the same test fixture for multiple tests. Any
-changes one test makes to the fixture do not affect other tests.
-
-As an example, let's write tests for a FIFO queue class named `Queue`, which has
-the following interface:
-
-```c++
-template <typename E>  // E is the element type.
-class Queue {
- public:
-  Queue();
-  void Enqueue(const E& element);
-  E* Dequeue();  // Returns NULL if the queue is empty.
-  size_t size() const;
-  ...
-};
-```
-
-First, define a fixture class. By convention, you should give it the name
-`FooTest` where `Foo` is the class being tested.
-
-```c++
-class QueueTest : public ::testing::Test {
- protected:
-  void SetUp() override {
-     q1_.Enqueue(1);
-     q2_.Enqueue(2);
-     q2_.Enqueue(3);
-  }
-
-  // void TearDown() override {}
-
-  Queue<int> q0_;
-  Queue<int> q1_;
-  Queue<int> q2_;
-};
-```
-
-In this case, `TearDown()` is not needed since we don't have to clean up after
-each test, other than what's already done by the destructor.
-
-Now we'll write tests using `TEST_F()` and this fixture.
-
-```c++
-TEST_F(QueueTest, IsEmptyInitially) {
-  EXPECT_EQ(q0_.size(), 0);
-}
-
-TEST_F(QueueTest, DequeueWorks) {
-  int* n = q0_.Dequeue();
-  EXPECT_EQ(n, nullptr);
-
-  n = q1_.Dequeue();
-  ASSERT_NE(n, nullptr);
-  EXPECT_EQ(*n, 1);
-  EXPECT_EQ(q1_.size(), 0);
-  delete n;
-
-  n = q2_.Dequeue();
-  ASSERT_NE(n, nullptr);
-  EXPECT_EQ(*n, 2);
-  EXPECT_EQ(q2_.size(), 1);
-  delete n;
-}
-```
-
-The above uses both `ASSERT_*` and `EXPECT_*` assertions. The rule of thumb is
-to use `EXPECT_*` when you want the test to continue to reveal more errors after
-the assertion failure, and use `ASSERT_*` when continuing after failure doesn't
-make sense. For example, the second assertion in the `Dequeue` test is
-`ASSERT_NE(nullptr, n)`, as we need to dereference the pointer `n` later, which
-would lead to a segfault when `n` is `NULL`.
-
-When these tests run, the following happens:
-
-1.  googletest constructs a `QueueTest` object (let's call it `t1`).
-2.  `t1.SetUp()` initializes `t1`.
-3.  The first test (`IsEmptyInitially`) runs on `t1`.
-4.  `t1.TearDown()` cleans up after the test finishes.
-5.  `t1` is destructed.
-6.  The above steps are repeated on another `QueueTest` object, this time
-    running the `DequeueWorks` test.
-
-**Availability**: Linux, Windows, Mac.
-
-## Invoking the Tests
-
-`TEST()` and `TEST_F()` implicitly register their tests with googletest. So,
-unlike with many other C++ testing frameworks, you don't have to re-list all
-your defined tests in order to run them.
-
-After defining your tests, you can run them with `RUN_ALL_TESTS()`, which
-returns `0` if all the tests are successful, or `1` otherwise. Note that
-`RUN_ALL_TESTS()` runs *all tests* in your link unit--they can be from
-different test suites, or even different source files.
-
-When invoked, the `RUN_ALL_TESTS()` macro:
-
-*   Saves the state of all googletest flags.
-
-*   Creates a test fixture object for the first test.
-
-*   Initializes it via `SetUp()`.
-
-*   Runs the test on the fixture object.
-
-*   Cleans up the fixture via `TearDown()`.
-
-*   Deletes the fixture.
-
-*   Restores the state of all googletest flags.
-
-*   Repeats the above steps for the next test, until all tests have run.
-
-If a fatal failure happens the subsequent steps will be skipped.
-
-> IMPORTANT: You must **not** ignore the return value of `RUN_ALL_TESTS()`, or
-> you will get a compiler error. The rationale for this design is that the
-> automated testing service determines whether a test has passed based on its
-> exit code, not on its stdout/stderr output; thus your `main()` function must
-> return the value of `RUN_ALL_TESTS()`.
->
-> Also, you should call `RUN_ALL_TESTS()` only **once**. Calling it more than
-> once conflicts with some advanced googletest features (e.g., thread-safe
-> [death tests](advanced.md#death-tests)) and thus is not supported.
-
-**Availability**: Linux, Windows, Mac.
-
-## Writing the main() Function
-
-Write your own main() function, which should return the value of
-`RUN_ALL_TESTS()`.
-
-You can start from this boilerplate:
-
-```c++
-#include "this/package/foo.h"
-#include "gtest/gtest.h"
-
-namespace {
-
-// The fixture for testing class Foo.
-class FooTest : public ::testing::Test {
- protected:
-  // You can remove any or all of the following functions if its body
-  // is empty.
-
-  FooTest() {
-     // You can do set-up work for each test here.
-  }
-
-  ~FooTest() override {
-     // You can do clean-up work that doesn't throw exceptions here.
-  }
-
-  // If the constructor and destructor are not enough for setting up
-  // and cleaning up each test, you can define the following methods:
-
-  void SetUp() override {
-     // Code here will be called immediately after the constructor (right
-     // before each test).
-  }
-
-  void TearDown() override {
-     // Code here will be called immediately after each test (right
-     // before the destructor).
-  }
-
-  // Objects declared here can be used by all tests in the test suite for Foo.
-};
-
-// Tests that the Foo::Bar() method does Abc.
-TEST_F(FooTest, MethodBarDoesAbc) {
-  const std::string input_filepath = "this/package/testdata/myinputfile.dat";
-  const std::string output_filepath = "this/package/testdata/myoutputfile.dat";
-  Foo f;
-  EXPECT_EQ(f.Bar(input_filepath, output_filepath), 0);
-}
-
-// Tests that Foo does Xyz.
-TEST_F(FooTest, DoesXyz) {
-  // Exercises the Xyz feature of Foo.
-}
-
-}  // namespace
-
-int main(int argc, char **argv) {
-  ::testing::InitGoogleTest(&argc, argv);
-  return RUN_ALL_TESTS();
-}
-```
-
-The `::testing::InitGoogleTest()` function parses the command line for
-googletest flags, and removes all recognized flags. This allows the user to
-control a test program's behavior via various flags, which we'll cover in
-the [AdvancedGuide](advanced.md). You **must** call this function before calling
-`RUN_ALL_TESTS()`, or the flags won't be properly initialized.
-
-On Windows, `InitGoogleTest()` also works with wide strings, so it can be used
-in programs compiled in `UNICODE` mode as well.
-
-But maybe you think that writing all those main() functions is too much work? We
-agree with you completely, and that's why Google Test provides a basic
-implementation of main(). If it fits your needs, then just link your test with
-gtest\_main library and you are good to go.
-
-NOTE: `ParseGUnitFlags()` is deprecated in favor of `InitGoogleTest()`.
-
-## Known Limitations
-
-*   Google Test is designed to be thread-safe. The implementation is thread-safe
-    on systems where the `pthreads` library is available. It is currently
-    _unsafe_ to use Google Test assertions from two threads concurrently on
-    other systems (e.g. Windows). In most tests this is not an issue as usually
-    the assertions are done in the main thread. If you want to help, you can
-    volunteer to implement the necessary synchronization primitives in
-    `gtest-port.h` for your platform.

-
-# The Problem
-
-Template and macro libraries often need to define many classes, functions, or
-macros that vary only (or almost only) in the number of arguments they take.
-It's a lot of repetitive, mechanical, and error-prone work.
-
-Variadic templates and variadic macros can alleviate the problem. However, while
-both are being considered by the C++ committee, neither is in the standard yet
-or widely supported by compilers. Thus they are often not a good choice,
-especially when your code needs to be portable. And their capabilities are still
-limited.
-
-As a result, authors of such libraries often have to write scripts to generate
-their implementation. However, our experience is that it's tedious to write such
-scripts, which tend to reflect the structure of the generated code poorly and
-are often hard to read and edit. For example, a small change needed in the
-generated code may require some non-intuitive, non-trivial changes in the
-script. This is especially painful when experimenting with the code.
-
-# Our Solution
-
-Pump (for Pump is Useful for Meta Programming, Pretty Useful for Meta
-Programming, or Practical Utility for Meta Programming, whichever you prefer) is
-a simple meta-programming tool for C++. The idea is that a programmer writes a
-`foo.pump` file which contains C++ code plus meta code that manipulates the C++
-code. The meta code can handle iterations over a range, nested iterations, local
-meta variable definitions, simple arithmetic, and conditional expressions. You
-can view it as a small Domain-Specific Language. The meta language is designed
-to be non-intrusive (s.t. it won't confuse Emacs' C++ mode, for example) and
-concise, making Pump code intuitive and easy to maintain.
-
-## Highlights
-
-*   The implementation is in a single Python script and thus ultra portable: no
-    build or installation is needed and it works cross platforms.
-*   Pump tries to be smart with respect to
-    [Google's style guide](https://github.com/google/styleguide): it breaks long
-    lines (easy to have when they are generated) at acceptable places to fit
-    within 80 columns and indent the continuation lines correctly.
-*   The format is human-readable and more concise than XML.
-*   The format works relatively well with Emacs' C++ mode.
-
-## Examples
-
-The following Pump code (where meta keywords start with `$`, `[[` and `]]` are
-meta brackets, and `$$` starts a meta comment that ends with the line):
-
-```
-$var n = 3     $$ Defines a meta variable n.
-$range i 0..n  $$ Declares the range of meta iterator i (inclusive).
-$for i [[
-               $$ Meta loop.
-// Foo$i does blah for $i-ary predicates.
-$range j 1..i
-template <size_t N $for j [[, typename A$j]]>
-class Foo$i {
-$if i == 0 [[
-  blah a;
-]] $elif i <= 2 [[
-  blah b;
-]] $else [[
-  blah c;
-]]
-};
-
-]]
-```
-
-will be translated by the Pump compiler to:
-
-```cpp
-// Foo0 does blah for 0-ary predicates.
-template <size_t N>
-class Foo0 {
-  blah a;
-};
-
-// Foo1 does blah for 1-ary predicates.
-template <size_t N, typename A1>
-class Foo1 {
-  blah b;
-};
-
-// Foo2 does blah for 2-ary predicates.
-template <size_t N, typename A1, typename A2>
-class Foo2 {
-  blah b;
-};
-
-// Foo3 does blah for 3-ary predicates.
-template <size_t N, typename A1, typename A2, typename A3>
-class Foo3 {
-  blah c;
-};
-```
-
-In another example,
-
-```
-$range i 1..n
-Func($for i + [[a$i]]);
-$$ The text between i and [[ is the separator between iterations.
-```
-
-will generate one of the following lines (without the comments), depending on
-the value of `n`:
-
-```cpp
-Func();              // If n is 0.
-Func(a1);            // If n is 1.
-Func(a1 + a2);       // If n is 2.
-Func(a1 + a2 + a3);  // If n is 3.
-// And so on...
-```
-
-## Constructs
-
-We support the following meta programming constructs:
-
-| `$var id = exp`                  | Defines a named constant value. `$id` is |
-:                                  : valid util the end of the current meta   :
-:                                  : lexical block.                           :
-| :------------------------------- | :--------------------------------------- |
-| `$range id exp..exp`             | Sets the range of an iteration variable, |
-:                                  : which can be reused in multiple loops    :
-:                                  : later.                                   :
-| `$for id sep [[ code ]]`         | Iteration. The range of `id` must have   |
-:                                  : been defined earlier. `$id` is valid in  :
-:                                  : `code`.                                  :
-| `$($)`                           | Generates a single `$` character.        |
-| `$id`                            | Value of the named constant or iteration |
-:                                  : variable.                                :
-| `$(exp)`                         | Value of the expression.                 |
-| `$if exp [[ code ]] else_branch` | Conditional.                             |
-| `[[ code ]]`                     | Meta lexical block.                      |
-| `cpp_code`                       | Raw C++ code.                            |
-| `$$ comment`                     | Meta comment.                            |
-
-**Note:** To give the user some freedom in formatting the Pump source code, Pump
-ignores a new-line character if it's right after `$for foo` or next to `[[` or
-`]]`. Without this rule you'll often be forced to write very long lines to get
-the desired output. Therefore sometimes you may need to insert an extra new-line
-in such places for a new-line to show up in your output.
-
-## Grammar
-
-```ebnf
-code ::= atomic_code*
-atomic_code ::= $var id = exp
-    | $var id = [[ code ]]
-    | $range id exp..exp
-    | $for id sep [[ code ]]
-    | $($)
-    | $id
-    | $(exp)
-    | $if exp [[ code ]] else_branch
-    | [[ code ]]
-    | cpp_code
-sep ::= cpp_code | empty_string
-else_branch ::= $else [[ code ]]
-    | $elif exp [[ code ]] else_branch
-    | empty_string
-exp ::= simple_expression_in_Python_syntax
-```
-
-## Code
-
-You can find the source code of Pump in [scripts/pump.py](../scripts/pump.py).
-It is still very unpolished and lacks automated tests, although it has been
-successfully used many times. If you find a chance to use it in your project,
-please let us know what you think! We also welcome help on improving Pump.
-
-## Real Examples
-
-You can find real-world applications of Pump in
-[Google Test](https://github.com/google/googletest/tree/master/googletest) and
-[Google Mock](https://github.com/google/googletest/tree/master/googlemock). The
-source file `foo.h.pump` generates `foo.h`.
-
-## Tips
-
-*   If a meta variable is followed by a letter or digit, you can separate them
-    using `[[]]`, which inserts an empty string. For example `Foo$j[[]]Helper`
-    generate `Foo1Helper` when `j` is 1.
-*   To avoid extra-long Pump source lines, you can break a line anywhere you
-    want by inserting `[[]]` followed by a new line. Since any new-line
-    character next to `[[` or `]]` is ignored, the generated code won't contain
-    this new line.

-//
-//   3. The parent process waits for the sub-process to terminate.
-//
-//   4. The parent process checks the exit code and error message of
-//   the sub-process.
-//
-// Examples:
-//
-//   ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
-//   for (int i = 0; i < 5; i++) {

-//
-// On the regular expressions used in death tests:
-//
-//   GOOGLETEST_CM0005 DO NOT DELETE
-//   On POSIX-compliant systems (*nix), we use the <regex.h> library,
-//   which uses the POSIX extended regex syntax.
-//
-//   On other platforms (e.g. Windows or Mac), we only support a simple regex
-//   syntax implemented as part of Google Test.  This limited
-//   implementation should be enough most of the time when writing
-//   death tests; though it lacks many features you can find in PCRE
-//   or POSIX extended regex syntax.  For example, we don't support
-//   union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
-//   repetition count ("x{5,7}"), among others.
-//
-//   Below is the syntax that we do support.  We chose it to be a
-//   subset of both PCRE and POSIX extended regex, so it's easy to
-//   learn wherever you come from.  In the following: 'A' denotes a
-//   literal character, period (.), or a single \\ escape sequence;
-//   'x' and 'y' denote regular expressions; 'm' and 'n' are for
-//   natural numbers.
-//
-//     c     matches any literal character c
-//     \\d   matches any decimal digit
-//     \\D   matches any character that's not a decimal digit
-//     \\f   matches \f
-//     \\n   matches \n
-//     \\r   matches \r
-//     \\s   matches any ASCII whitespace, including \n
-//     \\S   matches any character that's not a whitespace
-//     \\t   matches \t
-//     \\v   matches \v
-//     \\w   matches any letter, _, or decimal digit
-//     \\W   matches any character that \\w doesn't match
-//     \\c   matches any literal character c, which must be a punctuation
-//     .     matches any single character except \n
-//     A?    matches 0 or 1 occurrences of A
-//     A*    matches 0 or many occurrences of A
-//     A+    matches 1 or many occurrences of A
-//     ^     matches the beginning of a string (not that of each line)
-//     $     matches the end of a string (not that of each line)
-//     xy    matches x followed by y
-//
-//   If you accidentally use PCRE or POSIX extended regex features
-//   not implemented by us, you will get a run-time failure.  In that
-//   case, please try to rewrite your regular expression within the
-//   above syntax.
-//
-//   This implementation is *not* meant to be as highly tuned or robust
-//   as a compiled regex library, but should perform well enough for a
-//   death test, which already incurs significant overhead by launching
-//   a child process.
-//
-// Known caveats:
-//
-//   A "threadsafe" style death test obtains the path to the test
-//   program from argv[0] and re-executes it in the sub-process.  For
-//   simplicity, the current implementation doesn't search the PATH

-// This macro is used for implementing macros such as

-// if and only if EXPECT_DEATH and ASSERT_DEATH compile with the same parameters
-// on systems that support death tests. This allows one to write such a macro on
-// a system that does not support death tests and be sure that it will compile
-// on a death-test supporting system. It is exposed publicly so that systems
-// that have death-tests with stricter requirements than GTEST_HAS_DEATH_TEST
-// can write their own equivalent of EXPECT_DEATH_IF_SUPPORTED and
-// ASSERT_DEATH_IF_SUPPORTED.
-//
-// Parameters:
-//   statement -  A statement that a macro such as EXPECT_DEATH would test
-//                for program termination. This macro has to make sure this
-//                statement is compiled but not executed, to ensure that
-//                EXPECT_DEATH_IF_SUPPORTED compiles with a certain
-//                parameter if and only if EXPECT_DEATH compiles with it.
-//   regex     -  A regex that a macro such as EXPECT_DEATH would use to test
-//                the output of statement.  This parameter has to be
-//                compiled but not evaluated by this macro, to ensure that
-//                this macro only accepts expressions that a macro such as
-//                EXPECT_DEATH would accept.
-//   terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
-//                and a return statement for ASSERT_DEATH_IF_SUPPORTED.
-//                This ensures that ASSERT_DEATH_IF_SUPPORTED will not
-//                compile inside functions where ASSERT_DEATH doesn't
-//                compile.
-//
-//  The branch that has an always false condition is used to ensure that
-//  statement and regex are compiled (and thus syntactically correct) but
-//  never executed. The unreachable code macro protects the terminator
-//  statement from generating an 'unreachable code' warning in case
-//  statement unconditionally returns or throws. The Message constructor at
-//  the end allows the syntax of streaming additional messages into the

-//
-//  Range(begin, end [, step]) - Yields values {begin, begin+step,
-//                               begin+step+step, ...}. The values do not
-//                               include end. step defaults to 1.
-//  Values(v1, v2, ..., vN)    - Yields values {v1, v2, ..., vN}.
-//  ValuesIn(container)        - Yields values from a C-style array, an STL
-//  ValuesIn(begin,end)          container, or an iterator range [begin, end).
-//  Bool()                     - Yields sequence {false, true}.
-//  Combine(g1, g2, ..., gN)   - Yields all combinations (the Cartesian product
-//                               for the math savvy) of the values generated
-//                               by the N generators.
-//
-// For more details, see comments at the definitions of these functions below
-// in this file.
-//
-// The following statement will instantiate tests from the FooTest test suite
-// each with parameter values "meeny", "miny", and "moe".

-
-// To distinguish different instances of the pattern, (yes, you
-// can instantiate it more than once) the first argument to the
-// INSTANTIATE_TEST_SUITE_P macro is a prefix that will be added to the
-// actual test suite name. Remember to pick unique prefixes for different
-// instantiations. The tests from the instantiation above will have
-// these names:
-//
-//    * InstantiationName/FooTest.DoesBlah/0 for "meeny"
-//    * InstantiationName/FooTest.DoesBlah/1 for "miny"
-//    * InstantiationName/FooTest.DoesBlah/2 for "moe"

-//    * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
-//    * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
-//
-// You can use these names in --gtest_filter.
-//
-// This statement will instantiate all tests from FooTest again, each
-// with parameter values "cat" and "dog":

-//    * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
-//    * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
-//
-// Please note that INSTANTIATE_TEST_SUITE_P will instantiate all tests
-// in the given test suite, whether their definitions come before or
-// AFTER the INSTANTIATE_TEST_SUITE_P statement.
-//
-// Please also note that generator expressions (including parameters to the
-// generators) are evaluated in InitGoogleTest(), after main() has started.
-// This allows the user on one hand, to adjust generator parameters in order
-// to dynamically determine a set of tests to run and on the other hand,
-// give the user a chance to inspect the generated tests with Google Test
-// reflection API before RUN_ALL_TESTS() is executed.
-//
-// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
-// for more examples.
-//
-// In the future, we plan to publish the API for defining new parameter
-// generators. But for now this interface remains part of the internal
-// implementation and is subject to change.
-//
-//
-// A parameterized test fixture must be derived from testing::Test and from
-// testing::WithParamInterface<T>, where T is the type of the parameter
-// values. Inheriting from TestWithParam<T> satisfies that requirement because
-// TestWithParam<T> inherits from both Test and WithParamInterface. In more
-// complicated hierarchies, however, it is occasionally useful to inherit
-// separately from Test and WithParamInterface. For example:
-
-class BaseTest : public ::testing::Test {
-  // You can inherit all the usual members for a non-parameterized test
-  // fixture here.
-};
-
-class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {
-  // The usual test fixture members go here too.
-};
-
-TEST_F(BaseTest, HasFoo) {
-  // This is an ordinary non-parameterized test.
-}
-
-TEST_P(DerivedTest, DoesBlah) {
-  // GetParam works just the same here as if you inherit from TestWithParam.

-// This file implements a universal value printer that can print a
-// value of any type T:
-//
-//   void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr);
-//
-// A user can teach this function how to print a class type T by
-// defining either operator<<() or PrintTo() in the namespace that
-// defines T.  More specifically, the FIRST defined function in the
-// following list will be used (assuming T is defined in namespace
-// foo):
-//
-//   1. foo::PrintTo(const T&, ostream*)
-//   2. operator<<(ostream&, const T&) defined in either foo or the
-//      global namespace.
-//
-// However if T is an STL-style container then it is printed element-wise
-// unless foo::PrintTo(const T&, ostream*) is defined. Note that
-// operator<<() is ignored for container types.
-//
-// If none of the above is defined, it will print the debug string of
-// the value if it is a protocol buffer, or print the raw bytes in the
-// value otherwise.
-//
-// To aid debugging: when T is a reference type, the address of the
-// value is also printed; when T is a (const) char pointer, both the
-// pointer value and the NUL-terminated string it points to are
-// printed.
-//
-// We also provide some convenient wrappers:
-//
-//   // Prints a value to a string.  For a (const or not) char
-//   // pointer, the NUL-terminated string (but not the pointer) is
-//   // printed.
-//   std::string ::testing::PrintToString(const T& value);
-//
-//   // Prints a value tersely: for a reference type, the referenced
-//   // value (but not the address) is printed; for a (const or not) char
-//   // pointer, the NUL-terminated string (but not the pointer) is
-//   // printed.
-//   void ::testing::internal::UniversalTersePrint(const T& value, ostream*);
-//
-//   // Prints value using the type inferred by the compiler.  The difference
-//   // from UniversalTersePrint() is that this function prints both the
-//   // pointer and the NUL-terminated string for a (const or not) char pointer.
-//   void ::testing::internal::UniversalPrint(const T& value, ostream*);
-//
-//   // Prints the fields of a tuple tersely to a string vector, one
-//   // element for each field. Tuple support must be enabled in
-//   // gtest-port.h.
-//   std::vector<string> UniversalTersePrintTupleFieldsToStrings(
-//       const Tuple& value);
-//
-// Known limitation:
-//
-// The print primitives print the elements of an STL-style container
-// using the compiler-inferred type of *iter where iter is a
-// const_iterator of the container.  When const_iterator is an input
-// iterator but not a forward iterator, this inferred type may not
-// match value_type, and the print output may be incorrect.  In
-// practice, this is rarely a problem as for most containers
-// const_iterator is a forward iterator.  We'll fix this if there's an
-// actual need for it.  Note that this fix cannot rely on value_type
-// being defined as many user-defined container types don't have
-// value_type.

-// the macro to parse correctly.

-TYPED_TEST_SUITE(FooTest, MyTypes);

-// If the type list contains only one type, you can write that type

-  TypeParam n = this->value_;
-
-  // To visit static members of the fixture, add the TestFixture::
-  // prefix.
-  n += TestFixture::shared_;
-
-  // To refer to typedefs in the fixture, add the "typename
-  // TestFixture::" prefix.
-  typename TestFixture::List values;
-  values.push_back(n);
-  ...
-}
-
-TYPED_TEST(FooTest, HasPropertyA) { ... }
-
-// TYPED_TEST_SUITE takes an optional third argument which allows to specify a
-// class that generates custom test name suffixes based on the type. This should
-// be a class which has a static template function GetName(int index) returning
-// a string for each type. The provided integer index equals the index of the
-// type in the provided type list. In many cases the index can be ignored.
-//
-// For example:
-//   class MyTypeNames {

-// Type-parameterized tests are abstract test patterns parameterized
-// by a type.  Compared with typed tests, type-parameterized tests
-// allow you to define the test pattern without knowing what the type
-// parameters are.  The defined pattern can be instantiated with
-// different types any number of times, in any number of translation
-// units.
-//
-// If you are designing an interface or concept, you can define a
-// suite of type-parameterized tests to verify properties that any
-// valid implementation of the interface/concept should have.  Then,
-// each implementation can easily instantiate the test suite to verify
-// that it conforms to the requirements, without having to write
-// similar tests repeatedly.  Here's an example:
-
-#if 0
-
-// First, define a fixture class template.  It should be parameterized
-// by a type.  Remember to derive it from testing::Test.
-template <typename T>
-class FooTest : public testing::Test {

-// (the _P suffix is for "parameterized" or "pattern", whichever you
-// prefer):

-// Then, use TYPED_TEST_P() to define as many type-parameterized tests
-// for this type-parameterized test suite as you want.

-  // Inside a test, refer to TypeParam to get the type parameter.
-  TypeParam n = 0;

-// case.
-REGISTER_TYPED_TEST_SUITE_P(FooTest,
-                            DoesBlah, HasPropertyA);

-// Finally, you are free to instantiate the pattern with the types you
-// want.  If you put the above code in a header file, you can #include
-// it in multiple C++ source files and instantiate it multiple times.
-//
-// To distinguish different instances of the pattern, the first

-// A class for indicating whether an assertion was successful.  When
-// the assertion wasn't successful, the AssertionResult object
-// remembers a non-empty message that describes how it failed.
-//
-// To create an instance of this class, use one of the factory functions
-// (AssertionSuccess() and AssertionFailure()).
-//
-// This class is useful for two purposes:
-//   1. Defining predicate functions to be used with Boolean test assertions
-//      EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts
-//   2. Defining predicate-format functions to be
-//      used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
-//
-// For example, if you define IsEven predicate:
-//
-//   testing::AssertionResult IsEven(int n) {
-//     if ((n % 2) == 0)
-//       return testing::AssertionSuccess();
-//     else
-//       return testing::AssertionFailure() << n << " is odd";
-//   }
-//
-// Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
-// will print the message
-//
-//   Value of: IsEven(Fib(5))
-//     Actual: false (5 is odd)
-//   Expected: true
-//
-// instead of a more opaque
-//
-//   Value of: IsEven(Fib(5))
-//     Actual: false
-//   Expected: true
-//
-// in case IsEven is a simple Boolean predicate.
-//
-// If you expect your predicate to be reused and want to support informative
-// messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
-// about half as often as positive ones in our tests), supply messages for
-// both success and failure cases:
-//
-//   testing::AssertionResult IsEven(int n) {
-//     if ((n % 2) == 0)
-//       return testing::AssertionSuccess() << n << " is even";
-//     else
-//       return testing::AssertionFailure() << n << " is odd";
-//   }
-//
-// Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
-//
-//   Value of: IsEven(Fib(6))
-//     Actual: true (8 is even)
-//   Expected: false
-//
-// NB: Predicates that support negative Boolean assertions have reduced
-// performance in positive ones so be careful not to use them in tests
-// that have lots (tens of thousands) of positive Boolean assertions.
-//
-// To use this class with EXPECT_PRED_FORMAT assertions such as:
-//
-//   // Verifies that Foo() returns an even number.
-//   EXPECT_PRED_FORMAT1(IsEven, Foo());
-//
-// you need to define:
-//
-//   testing::AssertionResult IsEven(const char* expr, int n) {
-//     if ((n % 2) == 0)
-//       return testing::AssertionSuccess();
-//     else
-//       return testing::AssertionFailure()
-//         << "Expected: " << expr << " is even\n  Actual: it's " << n;
-//   }
-//
-// If Foo() returns 5, you will see the following message:
-//
-//   Expected: Foo() is even
-//     Actual: it's 5

-//   2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on
-//   pointers (in particular, C strings).  Therefore, if you use it
-//   with two C strings, you are testing how their locations in memory
-//   are related, not how their content is related.  To compare two C
-//   strings by content, use {ASSERT|EXPECT}_STR*().
-//
-//   3. {ASSERT|EXPECT}_EQ(v1, v2) is preferred to
-//   {ASSERT|EXPECT}_TRUE(v1 == v2), as the former tells you
-//   what the actual value is when it fails, and similarly for the
-//   other comparisons.
-//
-//   4. Do not depend on the order in which {ASSERT|EXPECT}_??()
-//   evaluate their arguments, which is undefined.

-//   5. These macros evaluate their arguments exactly once.

-# Customization Points
-
-The custom directory is an injection point for custom user configurations.
-
-## Header `gtest.h`
-
-### The following macros can be defined:
-
-*   `GTEST_OS_STACK_TRACE_GETTER_` - The name of an implementation of
-    `OsStackTraceGetterInterface`.
-*   `GTEST_CUSTOM_TEMPDIR_FUNCTION_` - An override for `testing::TempDir()`. See
-    `testing::TempDir` for semantics and signature.
-
-## Header `gtest-port.h`
-
-The following macros can be defined:
-
-### Flag related macros:
-
-*   `GTEST_FLAG(flag_name)`
-*   `GTEST_USE_OWN_FLAGFILE_FLAG_` - Define to 0 when the system provides its
-    own flagfile flag parsing.
-*   `GTEST_DECLARE_bool_(name)`
-*   `GTEST_DECLARE_int32_(name)`
-*   `GTEST_DECLARE_string_(name)`
-*   `GTEST_DEFINE_bool_(name, default_val, doc)`
-*   `GTEST_DEFINE_int32_(name, default_val, doc)`
-*   `GTEST_DEFINE_string_(name, default_val, doc)`
-
-### Logging:
-
-*   `GTEST_LOG_(severity)`
-*   `GTEST_CHECK_(condition)`
-*   Functions `LogToStderr()` and `FlushInfoLog()` have to be provided too.
-
-### Threading:
-
-*   `GTEST_HAS_NOTIFICATION_` - Enabled if Notification is already provided.
-*   `GTEST_HAS_MUTEX_AND_THREAD_LOCAL_` - Enabled if `Mutex` and `ThreadLocal`
-    are already provided. Must also provide `GTEST_DECLARE_STATIC_MUTEX_(mutex)`
-    and `GTEST_DEFINE_STATIC_MUTEX_(mutex)`
-*   `GTEST_EXCLUSIVE_LOCK_REQUIRED_(locks)`
-*   `GTEST_LOCK_EXCLUDED_(locks)`
-
-### Underlying library support features
-
-*   `GTEST_HAS_CXXABI_H_`
-
-### Exporting API symbols:
-
-*   `GTEST_API_` - Specifier for exported symbols.
-
-## Header `gtest-printers.h`
-
-*   See documentation at `gtest/gtest-printers.h` for details on how to define a
-    custom printer.

-// Environment-describing macros
-// -----------------------------
-//
-// Google Test can be used in many different environments.  Macros in
-// this section tell Google Test what kind of environment it is being
-// used in, such that Google Test can provide environment-specific
-// features and implementations.
-//
-// Google Test tries to automatically detect the properties of its
-// environment, so users usually don't need to worry about these
-// macros.  However, the automatic detection is not perfect.
-// Sometimes it's necessary for a user to define some of the following
-// macros in the build script to override Google Test's decisions.
-//
-// If the user doesn't define a macro in the list, Google Test will
-// provide a default definition.  After this header is #included, all
-// macros in this list will be defined to either 1 or 0.
-//
-// Notes to maintainers:
-//   - Each macro here is a user-tweakable knob; do not grow the list
-//     lightly.
-//   - Use #if to key off these macros.  Don't use #ifdef or "#if
-//     defined(...)", which will not work as these macros are ALWAYS
-//     defined.
-//
-//   GTEST_HAS_CLONE          - Define it to 1/0 to indicate that clone(2)
-//                              is/isn't available.
-//   GTEST_HAS_EXCEPTIONS     - Define it to 1/0 to indicate that exceptions
-//                              are enabled.
-//   GTEST_HAS_POSIX_RE       - Define it to 1/0 to indicate that POSIX regular
-//                              expressions are/aren't available.
-//   GTEST_HAS_PTHREAD        - Define it to 1/0 to indicate that <pthread.h>
-//                              is/isn't available.
-//   GTEST_HAS_RTTI           - Define it to 1/0 to indicate that RTTI is/isn't
-//                              enabled.
-//   GTEST_HAS_STD_WSTRING    - Define it to 1/0 to indicate that
-//                              std::wstring does/doesn't work (Google Test can
-//                              be used where std::wstring is unavailable).
-//   GTEST_HAS_SEH            - Define it to 1/0 to indicate whether the
-//                              compiler supports Microsoft's "Structured
-//                              Exception Handling".
-//   GTEST_HAS_STREAM_REDIRECTION
-//                            - Define it to 1/0 to indicate whether the
-//                              platform supports I/O stream redirection using
-//                              dup() and dup2().
-//   GTEST_LINKED_AS_SHARED_LIBRARY
-//                            - Define to 1 when compiling tests that use
-//                              Google Test as a shared library (known as
-//                              DLL on Windows).
-//   GTEST_CREATE_SHARED_LIBRARY
-//                            - Define to 1 when compiling Google Test itself
-//                              as a shared library.
-//   GTEST_DEFAULT_DEATH_TEST_STYLE
-//                            - The default value of --gtest_death_test_style.
-//                              The legacy default has been "fast" in the open
-//                              source version since 2008. The recommended value
-//                              is "threadsafe", and can be set in

-// Among the platforms, Cygwin, Linux, Mac OS X, and Windows have the

-// googletestframework@googlegroups.com (patches for fixing them are
-// even more welcome!).
-//
-// It is possible that none of the GTEST_OS_* macros are defined.
-
-// Feature-indicating macros
-// -------------------------
-//
-// Macros indicating which Google Test features are available (a macro
-// is defined to 1 if the corresponding feature is supported;
-// otherwise UNDEFINED -- it's never defined to 0.).  Google Test
-// defines these macros automatically.  Code outside Google Test MUST
-// NOT define them.
-//
-// These macros are public so that portable tests can be written.
-// Such tests typically surround code using a feature with an #if
-// which controls that code.  For example:
-//
-// #if GTEST_HAS_DEATH_TEST
-//   EXPECT_DEATH(DoSomethingDeadly());
-// #endif
-//
-//   GTEST_HAS_DEATH_TEST   - death tests
-//   GTEST_HAS_TYPED_TEST   - typed tests
-//   GTEST_HAS_TYPED_TEST_P - type-parameterized tests
-//   GTEST_IS_THREADSAFE    - Google Test is thread-safe.

-// Misc public macros
-// ------------------
-//
-//   GTEST_FLAG(flag_name)  - references the variable corresponding to
-//                            the given Google Test flag.
-
-// Internal utilities
-// ------------------
-//
-// The following macros and utilities are for Google Test's INTERNAL
-// use only.  Code outside Google Test MUST NOT USE THEM DIRECTLY.
-//
-// Macros for basic C++ coding:
-//   GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
-//   GTEST_ATTRIBUTE_UNUSED_  - declares that a class' instances or a
-//                              variable don't have to be used.
-//   GTEST_DISALLOW_ASSIGN_   - disables operator=.
-//   GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=.
-//   GTEST_MUST_USE_RESULT_   - declares that a function's result must be used.
-//   GTEST_INTENTIONAL_CONST_COND_PUSH_ - start code section where MSVC C4127 is
-//                                        suppressed (constant conditional).
-//   GTEST_INTENTIONAL_CONST_COND_POP_  - finish code section where MSVC C4127
-//                                        is suppressed.
-//
-// Synchronization:
-//   Mutex, MutexLock, ThreadLocal, GetThreadCount()
-//                            - synchronization primitives.
-//
-// Regular expressions:
-//   RE             - a simple regular expression class using the POSIX
-//                    Extended Regular Expression syntax on UNIX-like platforms
-//                    GOOGLETEST_CM0008 DO NOT DELETE
-//                    or a reduced regular exception syntax on other
-//                    platforms, including Windows.
-// Logging:
-//   GTEST_LOG_()   - logs messages at the specified severity level.
-//   LogToStderr()  - directs all log messages to stderr.
-//   FlushInfoLog() - flushes informational log messages.
-//
-// Stdout and stderr capturing:
-//   CaptureStdout()     - starts capturing stdout.
-//   GetCapturedStdout() - stops capturing stdout and returns the captured
-//                         string.
-//   CaptureStderr()     - starts capturing stderr.
-//   GetCapturedStderr() - stops capturing stderr and returns the captured
-//                         string.
-//
-// Integer types:
-//   TypeWithSize   - maps an integer to a int type.
-//   Int32, UInt32, Int64, UInt64, TimeInMillis
-//                  - integers of known sizes.
-//   BiggestInt     - the biggest signed integer type.
-//
-// Command-line utilities:
-//   GTEST_DECLARE_*()  - declares a flag.
-//   GTEST_DEFINE_*()   - defines a flag.
-//   GetInjectableArgvs() - returns the command line as a vector of strings.
-//
-// Environment variable utilities:
-//   GetEnv()             - gets the value of an environment variable.
-//   BoolFromGTestEnv()   - parses a bool environment variable.
-//   Int32FromGTestEnv()  - parses an Int32 environment variable.
-//   StringFromGTestEnv() - parses a string environment variable.
-//
-// Deprecation warnings:
-//   GTEST_INTERNAL_DEPRECATED(message) - attribute marking a function as
-//                                        deprecated; calling a marked function
-//                                        should generate a compiler warning

-// how do you know the pointer is really of type SubclassOfFoo?  It
-// could be a bare Foo, or of type DifferentSubclassOfFoo.  Thus,
-// when you downcast, you should use this macro.  In debug mode, we

-// easier to write, but generates horrible messages when there is a
-// compiler error, as gcc insists on printing out each template
-// argument, even if it has the default value (this means Types<int>
-// will appear as Types<int, None, None, ..., None> in the compiler
-// errors).
-//
-// Our solution is to combine the best part of the two approaches: a
-// user would write Types<T1, ..., TN>, and Google Test will translate
-// that to TypesN<T1, ..., TN> internally to make error messages
-// readable.  The translation is done by the 'type' member of the
-// Types template.

-// We don't want to require the users to write TemplatesN<...> directly,
-// as that would require them to count the length.  Templates<...> is much
-// easier to write, but generates horrible messages when there is a
-// compiler error, as gcc insists on printing out each template
-// argument, even if it has the default value (this means Templates<list>
-// will appear as Templates<list, NoneT, NoneT, ..., NoneT> in the compiler
-// errors).
-//
-// Our solution is to combine the best part of the two approaches: a
-// user would write Templates<T1, ..., TN>, and Google Test will translate
-// that to TemplatesN<T1, ..., TN> internally to make error messages
-// readable.  The translation is done by the 'type' member of the
-// Templates template.

-
-// A sample program demonstrating using Google C++ testing framework.
-
-// This sample shows how to write a simple unit test for a function,
-// using Google C++ testing framework.
-//
-// Writing a unit test using Google C++ testing framework is easy as 1-2-3:
-
-
-// Step 1. Include necessary header files such that the stuff your
-// test logic needs is declared.
-//
-// Don't forget gtest.h, which declares the testing framework.
-
-#include <limits.h>
-#include "sample1.h"
-#include "gtest/gtest.h"
-namespace {
-
-// Step 2. Use the TEST macro to define your tests.
-//
-// TEST has two parameters: the test case name and the test name.
-// After using the macro, you should define your test logic between a
-// pair of braces.  You can use a bunch of macros to indicate the
-// success or failure of a test.  EXPECT_TRUE and EXPECT_EQ are
-// examples of such macros.  For a complete list, see gtest.h.
-//
-// <TechnicalDetails>
-//
-// In Google Test, tests are grouped into test cases.  This is how we
-// keep test code organized.  You should put logically related tests
-// into the same test case.
-//
-// The test case name and the test name should both be valid C++
-// identifiers.  And you should not use underscore (_) in the names.
-//
-// Google Test guarantees that each test you define is run exactly
-// once, but it makes no guarantee on the order the tests are
-// executed.  Therefore, you should write your tests in such a way
-// that their results don't depend on their order.
-//
-// </TechnicalDetails>
-
-
-// Tests Factorial().
-
-// Tests factorial of negative numbers.
-TEST(FactorialTest, Negative) {
-  // This test is named "Negative", and belongs to the "FactorialTest"
-  // test case.
-  EXPECT_EQ(1, Factorial(-5));
-  EXPECT_EQ(1, Factorial(-1));
-  EXPECT_GT(Factorial(-10), 0);
-
-  // <TechnicalDetails>
-  //
-  // EXPECT_EQ(expected, actual) is the same as
-  //
-  //   EXPECT_TRUE((expected) == (actual))
-  //
-  // except that it will print both the expected value and the actual
-  // value when the assertion fails.  This is very helpful for
-  // debugging.  Therefore in this case EXPECT_EQ is preferred.
-  //
-  // On the other hand, EXPECT_TRUE accepts any Boolean expression,
-  // and is thus more general.
-  //
-  // </TechnicalDetails>
-}
-
-// Tests factorial of 0.
-TEST(FactorialTest, Zero) {
-  EXPECT_EQ(1, Factorial(0));
-}
-
-// Tests factorial of positive numbers.
-TEST(FactorialTest, Positive) {
-  EXPECT_EQ(1, Factorial(1));
-  EXPECT_EQ(2, Factorial(2));
-  EXPECT_EQ(6, Factorial(3));
-  EXPECT_EQ(40320, Factorial(8));
-}
-
-
-// Tests IsPrime()
-
-// Tests negative input.
-TEST(IsPrimeTest, Negative) {
-  // This test belongs to the IsPrimeTest test case.
-
-  EXPECT_FALSE(IsPrime(-1));
-  EXPECT_FALSE(IsPrime(-2));
-  EXPECT_FALSE(IsPrime(INT_MIN));
-}
-
-// Tests some trivial cases.
-TEST(IsPrimeTest, Trivial) {
-  EXPECT_FALSE(IsPrime(0));
-  EXPECT_FALSE(IsPrime(1));
-  EXPECT_TRUE(IsPrime(2));
-  EXPECT_TRUE(IsPrime(3));
-}
-
-// Tests positive input.
-TEST(IsPrimeTest, Positive) {
-  EXPECT_FALSE(IsPrime(4));
-  EXPECT_TRUE(IsPrime(5));
-  EXPECT_FALSE(IsPrime(6));
-  EXPECT_TRUE(IsPrime(23));
-}
-}  // namespace
-
-// Step 3. Call RUN_ALL_TESTS() in main().
-//
-// We do this by linking in src/gtest_main.cc file, which consists of
-// a main() function which calls RUN_ALL_TESTS() for us.
-//
-// This runs all the tests you've defined, prints the result, and
-// returns 0 if successful, or 1 otherwise.
-//
-// Did you notice that we didn't register the tests?  The
-// RUN_ALL_TESTS() macro magically knows about all the tests we
-// defined.  Isn't this convenient?

-// A sample program demonstrating using Google C++ testing framework.
-
-// In this example, we use a more advanced feature of Google Test called
-// test fixture.
-//
-// A test fixture is a place to hold objects and functions shared by
-// all tests in a test case.  Using a test fixture avoids duplicating
-// the test code necessary to initialize and cleanup those common
-// objects for each test.  It is also useful for defining sub-routines
-// that your tests need to invoke a lot.
-//
-// <TechnicalDetails>
-//
-// The tests share the test fixture in the sense of code sharing, not
-// data sharing.  Each test is given its own fresh copy of the
-// fixture.  You cannot expect the data modified by one test to be
-// passed on to another test, which is a bad idea.
-//
-// The reason for this design is that tests should be independent and
-// repeatable.  In particular, a test should not fail as the result of
-// another test's failure.  If one test depends on info produced by
-// another test, then the two tests should really be one big test.
-//
-// The macros for indicating the success/failure of a test
-// (EXPECT_TRUE, FAIL, etc) need to know what the current test is
-// (when Google Test prints the test result, it tells you which test
-// each failure belongs to).  Technically, these macros invoke a
-// member function of the Test class.  Therefore, you cannot use them
-// in a global function.  That's why you should put test sub-routines
-// in a test fixture.

-"""fuse_gtest_files.py v0.2.0
-Fuses Google Test source code into a .h file and a .cc file.
-
-SYNOPSIS
-       fuse_gtest_files.py [GTEST_ROOT_DIR] OUTPUT_DIR
-
-       Scans GTEST_ROOT_DIR for Google Test source code, and generates
-       two files: OUTPUT_DIR/gtest/gtest.h and OUTPUT_DIR/gtest/gtest-all.cc.
-       Then you can build your tests by adding OUTPUT_DIR to the include
-       search path and linking with OUTPUT_DIR/gtest/gtest-all.cc.  These
-       two files contain everything you need to use Google Test.  Hence
-       you can "install" Google Test by copying them to wherever you want.
-
-       GTEST_ROOT_DIR can be omitted and defaults to the parent
-       directory of the directory holding this script.
-
-EXAMPLES
-       ./fuse_gtest_files.py fused_gtest
-       ./fuse_gtest_files.py path/to/unpacked/gtest fused_gtest
-
-This tool is experimental.  In particular, it assumes that there is no
-conditional inclusion of Google Test headers.  Please report any
-problems to googletestframework@googlegroups.com.  You can read
-https://github.com/google/googletest/blob/master/googletest/docs/advanced.md for
-more information.

-The `gtest-config' script provides access to the necessary compile and linking
-flags to connect with Google C++ Testing Framework, both in a build prior to
-installation, and on the system proper after installation. The installation
-overrides may be issued in combination with any other queries, but will only
-affect installation queries if called on a built but not installed gtest. The
-installation queries may not be issued with any other types of queries, and
-only one installation query may be made at a time. The version queries and
-compiler flag queries may be combined as desired but not mixed. Different
-version queries are always combined with logical "and" semantics, and only the
-last of any particular query is used while all previous ones ignored. All
-versions must be specified as a sequence of numbers separated by periods.
-Compiler flag queries output the union of the sets of flags when combined.
-
- Examples:
-  gtest-config --min-version=1.0 || echo "Insufficient Google Test version."
-
-  g++ $(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp
-  g++ $(gtest-config --ldflags --libs) -o foo foo.o
-
-  # When using a built but not installed Google Test:
-  g++ $(../../my_gtest_build/scripts/gtest-config ...) ...
-
-  # When using an installed Google Test, but with installation overrides:
-  export GTEST_PREFIX="/opt"
-  g++ $(gtest-config --libdir="/opt/lib64" ...) ...

-"""Script for branching Google Test/Mock wiki pages for a new version.
-
-SYNOPSIS
-       release_docs.py NEW_RELEASE_VERSION
-
-       Google Test and Google Mock's external user documentation is in
-       interlinked wiki files.  When we release a new version of
-       Google Test or Google Mock, we need to branch the wiki files
-       such that users of a specific version of Google Test/Mock can
-       look up documenation relevant for that version.  This script
-       automates that process by:
-
-         - branching the current wiki pages (which document the
-           behavior of the SVN trunk head) to pages for the specified
-           version (e.g. branching FAQ.wiki to V2_6_FAQ.wiki when
-           NEW_RELEASE_VERSION is 2.6);
-         - updating the links in the branched files to point to the branched
-           version (e.g. a link in V2_6_FAQ.wiki that pointed to
-           Primer.wiki#Anchor will now point to V2_6_Primer.wiki#Anchor).
-
-       NOTE: NEW_RELEASE_VERSION must be a NEW version number for
-       which the wiki pages don't yet exist; otherwise you'll get SVN
-       errors like "svn: Path 'V1_7_PumpManual.wiki' is not a
-       directory" when running the script.
-
-EXAMPLE
-       $ cd PATH/TO/GTEST_SVN_WORKSPACE/trunk
-       $ scripts/release_docs.py 2.6  # create wiki pages for v2.6
-       $ svn status                   # verify the file list
-       $ svn diff                     # verify the file contents
-       $ svn commit -m "release wiki pages for v2.6"

-# if GTEST_OS_WINDOWS
-// WindowsDeathTest implements death tests on Windows. Due to the

-// always threadsafe, and Google Test considers the
-// --gtest_death_test_style=fast setting to be equivalent to
-// --gtest_death_test_style=threadsafe there.
-//
-// A few implementation notes:  Like the Linux version, the Windows
-// implementation uses pipes for child-to-parent communication. But due to
-// the specifics of pipes on Windows, some extra steps are required:
-//
-// 1. The parent creates a communication pipe and stores handles to both
-//    ends of it.
-// 2. The parent starts the child and provides it with the information
-//    necessary to acquire the handle to the write end of the pipe.
-// 3. The child acquires the write end of the pipe and signals the parent
-//    using a Windows event.
-// 4. Now the parent can release the write end of the pipe on its side. If
-//    this is done before step 3, the object's reference count goes down to
-//    0 and it is destroyed, preventing the child from acquiring it. The
-//    parent now has to release it, or read operations on the read end of
-//    the pipe will not return when the child terminates.
-// 5. The parent reads child's output through the pipe (outcome code and
-//    any possible error messages) from the pipe, and its stderr and then
-//    determines whether to fail the test.
-//
-// Note: to distinguish Win32 API calls from the local method and function
-// calls, the former are explicitly resolved in the global namespace.

-"""Unit test for Google Test test filters.
-
-A user can specify which test(s) in a Google Test program to run via either
-the GTEST_FILTER environment variable or the --gtest_filter flag.
-This script tests such functionality by invoking
-googletest-filter-unittest_ (a program written with Google Test) with different
-environments and command line flags.
-
-Note that test sharding may also influence which tests are filtered. Therefore,
-we test that here also.

-//
-// This file is generated by a script and quite long.  If you intend to
-// learn how Google Test works by reading its unit tests, read
-// gtest_unittest.cc instead.
-//
-// This is intended as a regression test for the Google Test predicate
-// assertions.  We compile it as part of the gtest_unittest target
-// only to keep the implementation tidy and compact, as it is quite
-// involved to set up the stage for testing Google Test using Google
-// Test itself.
-//
-// Currently, gtest_unittest takes ~11 seconds to run in the testing
-// daemon.  In the future, if it grows too large and needs much more
-// time to finish, we should consider separating this file into a
-// stand-alone regression test.

-   Flags/methods for returning states.
-
-   The SWIG conversion methods, as ConvertPtr, return an integer
-   that tells if the conversion was successful or not. And if not,
-   an error code can be returned (see swigerrors.swg for the codes).
-
-   Use the following macros/flags to set or process the returning
-   states.
-
-   In old versions of SWIG, code such as the following was usually written:
-
-     if (SWIG_ConvertPtr(obj,vptr,ty.flags) != -1) {
-       // success code
-     } else {
-       //fail code
-     }
-
-   Now you can be more explicit:
-
-    int res = SWIG_ConvertPtr(obj,vptr,ty.flags);
-    if (SWIG_IsOK(res)) {
-      // success code
-    } else {
-      // fail code
-    }
-
-   which is the same really, but now you can also do
-
-    Type *ptr;
-    int res = SWIG_ConvertPtr(obj,(void **)(&ptr),ty.flags);
-    if (SWIG_IsOK(res)) {
-      // success code
-      if (SWIG_IsNewObj(res) {
-        ...
-	delete *ptr;
-      } else {
-        ...
-      }
-    } else {
-      // fail code
-    }
-
-   I.e., now SWIG_ConvertPtr can return new objects and you can
-   identify the case and take care of the deallocation. Of course that
-   also requires SWIG_ConvertPtr to return new result values, such as
-
-      int SWIG_ConvertPtr(obj, ptr,...) {
-        if (<obj is ok>) {
-          if (<need new object>) {
-            *ptr = <ptr to new allocated object>;
-            return SWIG_NEWOBJ;
-          } else {
-            *ptr = <ptr to old object>;
-            return SWIG_OLDOBJ;
-          }
-        } else {
-          return SWIG_BADOBJ;
-        }
-      }
-
-   Of course, returning the plain '0(success)/-1(fail)' still works, but you can be
-   more explicit by returning SWIG_BADOBJ, SWIG_ERROR or any of the
-   SWIG errors code.
-
-   Finally, if the SWIG_CASTRANK_MODE is enabled, the result code
-   allows to return the 'cast rank', for example, if you have this
-
-       int food(double)
-       int fooi(int);
-
-   and you call
-
-      food(1)   // cast rank '1'  (1 -> 1.0)
-      fooi(1)   // cast rank '0'
-
-   just use the SWIG_AddCast()/SWIG_CheckState()

-/* -----------------------------------------------------------------------------
- * Type initialization:
- * This problem is tough by the requirement that no dynamic
- * memory is used. Also, since swig_type_info structures store pointers to
- * swig_cast_info structures and swig_cast_info structures store pointers back
- * to swig_type_info structures, we need some lookup code at initialization.
- * The idea is that swig generates all the structures that are needed.
- * The runtime then collects these partially filled structures.
- * The SWIG_InitializeModule function takes these initial arrays out of
- * swig_module, and does all the lookup, filling in the swig_module.types
- * array with the correct data and linking the correct swig_cast_info
- * structures together.
- *
- * The generated swig_type_info structures are assigned statically to an initial
- * array. We just loop through that array, and handle each type individually.
- * First we lookup if this type has been already loaded, and if so, use the
- * loaded structure instead of the generated one. Then we have to fill in the
- * cast linked list. The cast data is initially stored in something like a
- * two-dimensional array. Each row corresponds to a type (there are the same
- * number of rows as there are in the swig_type_initial array). Each entry in
- * a column is one of the swig_cast_info structures for that type.
- * The cast_initial array is actually an array of arrays, because each row has
- * a variable number of columns. So to actually build the cast linked list,
- * we find the array of casts associated with the type, and loop through it
- * adding the casts to the list. The one last trick we need to do is making
- * sure the type pointer in the swig_cast_info struct is correct.
- *
- * First off, we lookup the cast->type name to see if it is already loaded.
- * There are three cases to handle:
- *  1) If the cast->type has already been loaded AND the type we are adding
- *     casting info to has not been loaded (it is in this module), THEN we
- *     replace the cast->type pointer with the type pointer that has already
- *     been loaded.
- *  2) If BOTH types (the one we are adding casting info to, and the
- *     cast->type) are loaded, THEN the cast info has already been loaded by
- *     the previous module so we just ignore it.
- *  3) Finally, if cast->type has not already been loaded, then we add that
- *     swig_cast_info to the linked list (because the cast->type) pointer will
- *     be correct.
