Questions tagged [powermockito]

Use this tag for questions about PowerMockito, a Java Framework that allows the mocking of usually un-mockable types, i.e. statics, and private methods, in conjunction with the Mockito framework. Questions about using PowerMock with EasyMock should be tagged [powermock] instead.
