Yup I hear ya. MiniHBaseCluster adds an extra minute to the tests which kind of sucks. It gives
me peace of mind though

Subject: Re: Writing unit tests against HBase

What I'm currently looking for is a method of adding quick unit tests
(ie preferably run time of a few seconds) to test some algorithms that
read hbase data and perform some operations on it.  Mocking seems a much
better way to handle this, though I'm open to other suggestions.  I'll
try out MiniHBaseCluster anyway since I can't seem to get FakeHBase to work.

The benefit you get is that you no longer need to mock HBase responses and you will be talking
to an actual cluster running similar code to the one you will have running in prod, so will
be more reliable. Obviously the downside is that instead of mocking responses, you will have
to populate data in HBase tables but I still feel this is more intuitive and reliable.
