Subject Re: testing, powermock, jmockit - from pow-wow

I've used mockito a few times, and it's great... but it can make your
tests very brittle.  It can also be hard to successfully use if the
code is complex.  For example I had a class that took an HBaseAdmin,
and i mocked out the few calls it used.  Then when I needed to access
Configuration, things went downhill fast.  I ended up abandoning
easymock even.

The issue ultimately stems from not writing your code in a certain way
with a minimal of easy to mock external interfaces.  When this isn't
true, then easymock does nothing for you.  It can save your bacon if
you are trying to unit test something deep though.

The other question I guess is integration testing... there is no
specific good reason why everything is done in 1 jvm, except 'because
we can'.  a longer lived 'minicluster' could amortize the cost of
running one.
