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.

PowerMockito is used in addition with the Java Framework Mockito. PowerMockito's main strength is the ability to mock Static and Private Methods. A good example of PowerMocktio is the ability to mock Singletons which are generally difficult when unit testing.

Heres a great link to starting out with PowerMockito: Using PowerMock with Mockito
