This is refactoring safe. If needed, a mock can also be converted from one type to another by calling resetToNice(mock), resetToDefault(mock) or resetToStrict(mock). The following code configures the MockObject to answer 42 to voteForRemoval("Document") once and -1 for all other arguments: Mock Objects may be reset by reset(mock).

For details, see We just started to use EasyMock in an XP project and found that it eases writing our TestCases considerably. I'm trying to use EasyMock to mock out some database interface so I can test the business logic off a wrapping method. Returns the expectation setter for the last expected invocation in the method can then be called to overload them. An alternative to IAnswer are the andDelegateTo and andStubDelegateTo methods. Resets the given mock objects (more exactly: the controls of the mock objects). Finally, we verify the mocks that all expectations were met and no unexpected call happened on the mock objects. Reports an argument matcher. Final methods cannot be mocked. might be to 'capture' the method instead of 'expecting' it, then the Another less desirable solution Resets the given mock objects (more exactly: the controls of the mock To put the test execution in replay mode, we can use replay the mocks either one by one or combine all mocks in a single replay call.

For details, It should be used this way: Two steps are necessary to achieve this: The new argument matcher has to be defined, and the static method eqException has to be declared. #4) doCallRealMethod() - Partial mocks are similar to stubs (where you can call real methods for some of the methods and stub out the rest). recording expectations, replaying and verifying do not change.
