You might need to add reset(mockObject) before expect(). Inside an IAnswer callback, the arguments passed to the mock call are available via EasyMock.getCurrentArgument(int index). We can create the mock object using EasyMock but EasyMock doesn't allow us to mock . As an example, we set up two mock objects for the interface IMyInterface, and we expect the calls mock1.a() and mock2.a() ordered, then an open number of calls to mock1.c() and mock2.c(), and finally mock2.b() and mock1.b(), in this order: To relax the expected call counts, there are additional methods that may be used instead of times(int count): If no call count is specified, one call is expected. To verify that the specified behavior has been used, we have to call verify(mock): If the method is not called on the Mock Object, we now get the following exception: The message of the exception lists all missed expectations. Expects an int argument less than or equal to the given value. Expects any long argument.

For backward Here is my current test but it's missing any real purpose because I can't figure out how to specify the correct method reference. When we use expectLastCall() and andAnswer() to mock void methods, we can use getCurrentArguments() to get the arguments passed to the method and perform some action on it.
