My testing procedure is a bit different than you might expect, so here's the deal:
The game project is currently about 15% finished and will most probably be finished around January 2010 (current play time is about 5 to 6 hours). I am uploading new beta versions about once every two, maybe three weeks (testing has already begun, we're already at the third beta version). Each new version will add at least two hours of play time, and I am looking for people willing to play through each new version and give feedback on the new stuff (meaning you would have to put in about two hours once every two weeks). Ideally I am looking for people willing to stay with the project for a while, but of course I understand that not everyone will be able to stay with the project for several months. You are of course welcome to join for a shorter period of time, and you can of course always return at a later time if you have to take some time off from beta testing. Beta testing discussion is already taking place on the defaultgames forum, so you would have to register an account there to participate.
Here are a couple screenshots to show you what you're getting yourselves into:
