Subject Re: Writing unit tests against HBase

Why don't you spin up a mini cluster for your tests (there is a MiniHBaseCluster which brings
up an in-memory cluster for testing and you can tear it down at the end of your test)? 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.

I figured I'd take a look as I was about to try using Mockito
(https://code.google.com/p/mockito/) to try to implement unit testing of
some of our code that accesses HBase.  The example tests in there are
all Scala, and I'm not having much success using them in Java.  Do you
know if there's any example Java tests that make use of fake-hbase?
