Basically what you're talking about is a unit testing and continuous
integration framework. VASSAL is using JUnit for unit testing, but we're
right at the beginning of writing tests. We're writing tests for all new
code, but we have heaps of old code which is in desperate need of tests.
If you'd like to help us write tests, that would be quite welcome.

If you look at the trunk, our tests are under the test/ directory. Right
now, Ken Stevens is heading up writing tests for old code. Hopefully this
will get his attention, and he'll comment on where you might start.

(BTW, have you registered at SF yet? I can't add you as a developer until
you do that.)
