Unit testing Google wave robots in Java

Any tips or best practices for unit testing Google Wave robots written in Java? I'm expecting to deploy on AppEngine, if that helps. I'm a fan of TDD but new to both Wave Robots开发者_Go百科 and AppEngine, so I'm hoping to use TDD to help me explore the design space.

After a few hours of reading and tinkering, I've come up with a solution combining AppEngine, JUnit, and Wave. I describe all the details in my blog post: http://paulgestwicki.wordpress.com/2010/06/18/unit-testing-google-wave-robots/
