I filed HBASE-3555, and I listed the following reasons; - test groups allow us to separate slow/fast tests from each other - surefire support for running specific groups would allow 'check in tests' vs 'hudson/integration tests' (ie fast/slow) - it supports all the features of junit 4, plus it is VERY similar, making for the transition easy. - they have assertEquals(byte[],byte[])
What do other people think?
