Inspired by jMock, EasyMock, and Hamcrest, and designed with C++'s specifics in mind, Google C++ Mocking Framework (or Google Mock for short) is a library for writing and using C++ mock classes. Google Mock: o lets you create mock classes trivially using simple macros, o supports a rich set of matchers and actions, o handles unordered, partially ordered, or completely ordered expectations, o is extensible by users, and o works on Linux, Mac OS X, Windows, Windows Mobile, minGW, and Symbian.
