Google's framework for writing and using C++ mock classes. It can help you
|
|
|
|
|
derive better designs of your system and write better tests.

gMock:
|
|
|
|
|
|
|
|
|
|
- provides a declarative syntax for defining mocks,
|
|
|
|
|
- can define partial (hybrid) mocks, which are a cross of real and mock
|
|
|
|
|
objects,
|
|
|
|
|
- handles functions of arbitrary types and overloaded functions,
|
|
|
|
|
- comes with a rich set of matchers for validating function arguments,
|
|
|
|
|
- uses an intuitive syntax for controlling the behavior of a mock,
|
|
|
|
|
- does automatic verification of expectations (no record-and-replay needed),
|
|
|
|
|
- allows arbitrary (partial) ordering constraints on function calls to be
|
|
|
|
|
expressed,
|
|
|
|
|
- lets a user extend it by defining new matchers and actions.
|
|
|
|
|
- does not use exceptions, and
|
|
|
|
|
- is easy to learn and use.

Google Mock is a part of

[Google Test C++ testing framework](http://github.com/google/googletest/) and a
|
|
|
|
|
subject to the same requirements.
