++++ on getting some automated testing into the tree.  The lack of that
right now is mostly based on rapid turnover in the current code, and
lack of time, not lack of interest.

Patches that start to integrate automated testing into the tree are
welcomed as long as they can be executed on both MS.NET and Mono using
nant (we're very strongly bi-platform).

My suggestion is to start small on one area of the code and get that
well tested, then extend througout.  I think you'll get a lot of support
from everyone in the dev team if you jump in and start contributing
here.

More work on test engineering is one of my new years resolutions.

There is no silver bullet.  Plus, werewolves make better neighbors
than zombies, and they tend to keep the vampire population down.
