> We should introduce PowerMock into our unit tests so that we don't have to expose methods
intended to be used by unit tests.
> Here was Benoit's reply to a user of asynchbase about testability:
> OpenTSDB has unit tests that are mocking out HBaseClient just fine
> [1].  You can mock out pretty much anything on the JVM: final,
> private, JDK stuff, etc.  All you need is the right tools.  I've been
> very happy with PowerMock.  It supports Mockito and EasyMock.
> I've never been keen on mutilating public interfaces for the sake of
> testing.  With tools like PowerMock, we can keep the public APIs tidy
> while mocking and overriding anything, even in the most private guts
> of the classes.
