There is basically nothing in the way of unit tests which I am aware
of.  We rely on code review and functional testing primarily.

I have some plans to introduce some functional tests from a guests
perspective.  I hope to have these ready in the 4.7 timeframe, but there
is nothing similar which I am aware of.
