Internal CL 156157936, which was published in commit
fe402c27790ff1cc9a7e17c5d0aea4ebe7fd8a71, introduced undefined behavior
by casting a base class (internal::{Naggy,Nice,Strict}Base<MockClass>,
using the curiously recurring template pattern) pointer to a derived
class ({Naggy,Nice,Strict}Mock<MockClass>), in the base class'
constructor. At that point, the object isn't guaranteed to have taken on
the shape of the derived class, and casting is undefined behavior.
The undefined behavior was caught by Chrome's CFI build bot [1], and
prevents rolling googletest past that commit / CL.
This commit simplifies the {Naggy,Nice,Strict}Mock class hierarchy in
a way that removes the undefined behavior.

// 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.
