As an example, the following code will not compile, as the type of the provided return value does not match the method's return value: Instead of calling expect(T value) to retrieve the object for setting the return value, we may also use the object returned by expectLastCall(). So you want to keep the normal behavior Positive return values are a vote for removal. EasyMock can save a lot of legwork and make unit tests a lot faster to write. If we just want to mock void method and don't want to perform any logic, we can simply use expectLastCall ().andVoid right after calling void method on mocked object. For details, see Important:The instantiator is kept statically so it will stick between your unit tests.

I don't like it but one option might be to add There is one error that we have not handled so far: If we specify behavior, we would like to verify that it is actually used. Let's test the MathApplication class, by injecting in it a mock of calculatorService. Spring adsbygoogle window.adsbygoogle .push Find centralized, trusted content and collaborate around the technologies you use most. In case of failure, you can replace the default instantiator with: You set this new instantiator using ClassInstantiatorFactory.setInstantiator(). dao expectLastCall().once(); " otherObj " see the EasyMock documentation. You could also use EasyMock.isA(OtherObj.class) for a little more type safety.

I don't like it but one option might be to add EasyMock annotations on method references. objects). Not only is it well crafted and easy to use. Good luck! Note the method takes long as an argument whereas the default 0 is an integer. In case, someone is here because he/she was trying to expect a different behavior for a mock than from the init/before behavior. Using Kolmogorov complexity to measure difficulty of problems?

Sometimes we want to mock void methods. Creates a mock object, of the requested type, that implements the given interface You can also have a look at the samples The IMocksControl allows to create more than one Mock Object, and so it is possible to check the order of method calls between mocks. Otherwise, we would end up with different assertion exceptions like so: The expected and actual numbers start varying depending on the number of calls.
