This Mockito JUnit Runner implementation ignores unused stubs
(e.g. it remains 'silent' even if unused stubs are present).
This was the behavior of Mockito JUnit runner in versions 1.*.
Using this implementation of the runner is not recommended.
Engineers should care for removing unused stubbings because they are dead code,
they add unnecessary details, potentially making the test code harder to comprehend.
If you have good reasons to use the silent runner, let us know at the mailing list
or raise an issue in our issue tracker.
