How can I unit test Flex applications from within the IDE or a build script? | I'm currently working on an application with a frontend written in Adobe Flex 3. I'm aware of [FlexUnit](http://code.google.com/p/as3flexunitlib/) but what I'd really like is a unit test runner for Ant/NAnt and a runner that integrates with the Flex Builder IDE (AKA Eclipse). Does one exist? 


Also, are there any other resources on how to do Flex development "the right way" besides the [Cairngorm microarchitecture](http://labs.adobe.com/wiki/index.php/Cairngorm) example?
