37// Implements class templates NiceMock and StrictMock.
38//
39// Given a mock class MockFoo that is created using Google Mock,
40// NiceMock<MockFoo> is a subclass of MockFoo that allows
41// uninteresting calls (i.e. calls to mock methods that have no
42// EXPECT_CALL specs), and StrictMock<MockFoo> is a subclass of
43// MockFoo that treats all uninteresting calls as errors.
44//
45// NiceMock and StrictMock "inherits" the constructors of their
46// respective base class, with up-to $n arguments.  Therefore you can
47// write NiceMock<MockFoo>(5, "a") to construct a nice mock where
48// MockFoo has a constructor that accepts (int, const char*), for
49// example.
50//
51// A known limitation is that NiceMock<MockFoo> and
52// StrictMock<MockFoo> only works for mock methods defined using the
53// MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.  If a
54// mock method is defined in a base class of MockFoo, the "nice" or
55// "strict" modifier may not affect it, depending on the compiler.  In
56// particular, nesting NiceMock and StrictMock is NOT supported.
57//
58// Another known limitation is that the constructors of the base mock
59// cannot have arguments passed by non-const reference, which are
60// banned by the Google C++ style guide anyway.
