MEX (Octave/Matlab) interface also needs to have unit testing.

I have very little experience with Matlab -- is there a good unit testing framework that I could use?

Bonus points if it works in Octave as well, so I can run it on travis-ci.

The whole MEX interface more or less needs a complete rewrite, anyway. I would like to do all of those at once.
