# 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](https://easymock.org/)
* [Hamcrest](https://code.google.com/p/hamcrest/)
It is 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.
- Is easy to learn and use.
Details and examples can be found here:
* [gMock for Dummies](https://google.github.io/googletest/gmock_for_dummies.html)
* [Legacy gMock FAQ](https://google.github.io/googletest/gmock_faq.html)
* [gMock Cookbook](https://google.github.io/googletest/gmock_cook_book.html)
* [gMock Cheat Sheet](https://google.github.io/googletest/gmock_cheat_sheet.html)
GoogleMock is a part of
[GoogleTest C++ testing framework](https://github.com/google/googletest/) and a
subject to the same requirements.

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

// made the Action<U()> conversion operator eagerly convert the R value to

// in the documentation for Return, making reference-like types such as
// std::string_view not safe to use as U where the input type R is a
// value-like type such as std::string.
//
// The example the commit gave was not very clear, nor was the issue
// thread (https://github.com/google/googlemock/issues/86), but it seems
// the worry was about reference-like input types R that flatten to a
// value-like type U when being implicitly converted. An example of this
// is std::vector<bool>::reference, which is often a proxy type with an
// reference to the underlying vector:
//
// // Helper method: have the mock function return bools according
// // to the supplied script.
// void SetActions(MockFunction<bool(size_t)>& mock,
// const std::vector<bool>& script) {
// for (size_t i = 0; i < script.size(); ++i) {
// EXPECT_CALL(mock, Call(i)).WillOnce(Return(script[i]));
// }
// }
//
// TEST(Foo, Bar) {
// // Set actions using a temporary vector, whose operator[]
// // returns proxy objects that references that will be
// // dangling once the call to SetActions finishes and the
// // vector is destroyed.
// MockFunction<bool(size_t)> mock;
// SetActions(mock, {false, true});
//
// EXPECT_FALSE(mock.AsStdFunction()(0));
// EXPECT_TRUE(mock.AsStdFunction()(1));
// }
//
// This eager conversion helps with a simple case like this, but doesn't
// fully make these types work in general. For example the following still
// uses a dangling reference:
//
// TEST(Foo, Baz) {
// MockFunction<std::vector<std::string>()> mock;
//
// // Return the same vector twice, and then the empty vector
// // thereafter.
// auto action = Return(std::initializer_list<std::string>{
// "taco", "burrito",

// There are two quirks here:
//
// * Unlike most forwarding functions, we pass scalars through by value.
// This isn't strictly necessary because an lvalue reference would work
// fine too and be consistent with other non-reference types, but it's
// perhaps less surprising.
//
// For example if the mocked function has signature void(int), then it
// might seem surprising for the user's initial action to need to be
// convertible to Action<void(const int&)>. This is perhaps less
// surprising for a non-scalar type where there may be a performance
// impact, or it might even be impossible, to pass by value.
//
// * More surprisingly, `const T&` is often not a const reference type.
// By the reference collapsing rules in C++17 [dcl.ref]/6, if T refers to
// U& or U&& for some non-scalar type U, then InitialActionArgType<T> is
// U&. In other words, we may hand over a non-const reference.
//
// So for example, given some non-scalar type Obj we have the following
// mappings:
//
// T InitialActionArgType<T>
// ------- -----------------------
// Obj const Obj&
// Obj& Obj&
// Obj&& Obj&
// const Obj const Obj&
// const Obj& const Obj&
// const Obj&& const Obj&
//
// In other words, the initial actions get a mutable view of an non-scalar
// argument if and only if the mock function itself accepts a non-const
// reference type. They are never given an rvalue reference to an
// non-scalar type.
//
// This situation makes sense if you imagine use with a matcher that is
// designed to write through a reference. For example, if the caller wants
// to fill in a reference argument and then return a canned value:
//
// EXPECT_CALL(mock, Call)
// .WillOnce(DoAll(SetArgReferee<0>(17), Return(19)));

// 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.

// (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 std::ref(). For
// example,
//
// InvokeArgument<1>(5, string("Hello"), std::ref(foo))
//
// passes 5 and string("Hello") by value, and passes foo by
// reference.
//
// 2. If the callable takes an argument by reference but std::ref() 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.

// 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.

// A MockFunction<F> type has one mock method whose type is
// internal::SignatureOfT<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<internal::SignatureOfT<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());
// }
//
// The internal::SignatureOfT<F> indirection allows to use other types
// than just function signature type. This is typically useful when
// providing a mock for a predefined std::function type. Example:
//
// using FilterPredicate = std::function<bool(string)>;
// void MyFilterAlgorithm(FilterPredicate predicate);
//
// TEST(FooTest, FilterPredicateAlwaysAccepts) {
// MockFunction<FilterPredicate> predicateMock;
// EXPECT_CALL(predicateMock, Call(_)).WillRepeatedly(Return(true));
// MyFilterAlgorithm(predicateMock.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.
