Simulating Method Behavior As mentioned earlier, we might sometimes need to simulate the behavior of the void method. However, we can use expectLastCall() along with andAnswer() to mock void methods. Expects a string that matches the given regular expression. This method is needed to define own argument You just need to call the method on your mock before calling expectLastCall() So you expectation would look like this: userService.addUser(newUser1); EasyMock.expectLastCall(); EasyMock.replay(dbMapper); userService.addUser(newUser1); captured argument would have to have a way to call/trigger it so it can be Sometimes we would like our mock object to return a value or throw an exception that is created at the time of the actual call.
