Should we use PowerMock?
PowerMock was a must in order to achieve our goal of 80% code coverage. For me, I’ve come to a conclusion that necessity of using PowerMock in a project is an indicator for bad code design. In later projects, PowerMock is not used at all. If something cannot be unit tested with Mockito then the class is refactored.
