The failure occurs immediately at the first method call exceeding the limit: If there are too few calls, verify(mock) throws an AssertionError: For specifying return values, we wrap the expected call in expect(T value) and specify the return value with the method andReturn(Object returnValue) on the object returned by expect(T value). Does a summoned creature play immediately after being summoned by a ready action? @Henri Very true. 4.3.

We just started to use EasyMock in an XP project and found that it eases writing our TestCases considerably. In order to be able to test that a method throws the appropriate exceptions when required, a mock object must be able to throw an exception when called.

We were about to implement our own Mocking based on reflect.Proxy, but seems like you saved us lot of trouble. control of the mock object) the on and off. Here is the test without the definition of the Mock Object: For many tests using EasyMock, we only need a static import of methods of org.easymock.EasyMock. If you can't get a reference to the object itself in your test code, you could use EasyMock.anyObject() as the expected argument to yourinsert method. How do you assert that a certain exception is thrown in JUnit tests? 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. is less than the given delta. As an example, we check the workflow for document removal. Expects a float argument less than or equal to the given value. is disabled by default, and the mock object will return.
