Test Driven Development (Conjure and Ruby. Flash?)

So. Conjure is coming along slowly. The stranger aspects of the template settings class are working now, according the the testing I have done. I have been trying to work in the test driven development workflow. I can see why it is a good idea, it just takes a bit of time to really get used to. The hard part has been forcing myself to write the test first every time. A mental shift like that is never easy.
Unit testing is easy in Ruby because of Test::Unit. I’m not sure that there is a similar system in Flash for such unit testing, and if not, I will probably develop one myself. Yes, I know that I should be working on an object information dumper for Jesse Freeman, but seriously, a unit testing system is probably better in the long run. And of course, I need to finish Conjure, because it will be awesome.
