It is done using the verify () method. If classUnderTest.addDocument("New Document", new byte[0]) calls the expected method with a wrong argument, the Mock Object will complain with an AssertionError: All missed expectations are shown, as well as all fulfilled expectations for the unexpected call (none in this case).
