// 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
// DoAll
// DoDefault
// IgnoreResult
// Throw
// ACTION()-generated
// ACTION_P()-generated
// ACTION_P2()-generated
// Matchers:
// _
// A
// An
// Eq
// Gt, Lt, Ge, Le, Ne
// NotNull
// Ref
// TypedEq
// DoubleEq
// FloatEq
// NanSensitiveDoubleEq
// NanSensitiveFloatEq
// ContainsRegex
// MatchesRegex
// EndsWith
// HasSubstr
// StartsWith
// StrCaseEq
// StrCaseNe
// StrEq
// StrNe
// ElementsAre
// ElementsAreArray
// ContainerEq
// Field
// Property
// ResultOf(function)
// Pointee
// Truly(predicate)
// 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.
