Here is a simplified version of the method I'm trying to test: Ok so using EasyMock I've mocked the service.getObj(myObj) call and that works fine.

Suppressing a method using Powermock results in AssertionError - Coderanch While we believe that this content benefits our community, we have not yet thoroughly reviewed it.

Find centralized, trusted content and collaborate around the technologies you use most. (testServletRequest.getAttribute(AuthConfig.DRUID_AUTHENTICATION_RESULT)). Let us write a second test.

Expects a byte argument greater than or equal to the given value. Finally, we learned to write a complete test with an example. For that you should do something like. Since EasyMock 2.2, the object returned by expectLastCall() and expect(T value) provides the method andAnswer(IAnswer answer) which allows to specify an implementation of the interface IAnswer that is used to create the return value or exception. By default, a mock is thread safe (unless. possible". Have a question about this project? It would look something like: Also, PowerMock has the ability to expect an object to be constructed, so you could look into that if you wanted. recording expectations, replaying and verifying do not change. If we are not using these annotations, then we can skip using the following solutions. Expects a byte array that is equal to the given array, i.e. multithreaded environment. Suppose MathApplication should call the CalculatorService.serviceUsed () method only once, then it should not be able to call CalculatorService.serviceUsed () more than once. Easymock expects the registerReceiver method to be called with exact parameter with which it is told to expect, So to avoid this ,while expecting any method and writing its behaviour, use anyObject() method like this:-, by this, easymock understands that it has to mock all the calls to expected method, when any object of IntentFilter is passed as a parameter.
