How do I enable Mockito debug messages?

Mockito 1.9.0 introduced listeners and now bundles a verbose logger:

So basically if you want simple and stupid logs, just do the following:

List mockWithLogger = mock(List.class, withSettings().verboseLogging());

See http://docs.mockito.googlecode.com/hg/latest/org/mockito/MockSettings.html#verboseLogging() for more information

Cheers,
