VoodooMock is a mock object framework that fully automates the repetitive tasks associated with writing mock objects for C++ unit tests. Similar to other frameworks, VoodooMock provides an expectation storage and verification engine. But unlike other frameworks, VoodooMock also automates the generation of stubs, and rerouting calls to the stubs, without requiring any macros or unnecessary interfaces. VoodooMock is available under the GPL, and is successfully deployed in at least three production projects.
