# Googletest Mocking (gMock) Framework
|
|
|
|
|
|
|
|
|
|
### Overview
|
|
|
|
|
|
|
|
|
|
Google's framework for writing and using C++ mock classes. It can help you
|
|
|
|
|
derive better designs of your system and write better tests.
|
|
|
|
|
|
|
|
|
|
It is inspired by:
|
|
|
|
|
|
|
|
|
|
* [jMock](http://www.jmock.org/)
|
|
|
|
|
* [EasyMock](http://www.easymock.org/)
|
|
|
|
|
* [Hamcrest](http://code.google.com/p/hamcrest/)
|
|
|
|
|
|
|
|
|
|
It is designed with C++'s specifics in mind.

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.
|
|
|
|
|
- Is easy to learn and use.
