// 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.
