You can see a basic version running for my personal site. It is super barebones, but it should give you an idea of what exactly is possible.
Tests are written using Twill, which allows for easy functional testing of web apps.
The mailing list for the project is located at google groups: http://groups.google.com/group/django-testing
Originally Kong was called paradigm, because it was going to change the way we thought about deployment. After much convincing from coworkers that this was too enterprisey, during the Djangocon 09 sprints, I was given the name Donkey Kong. I thought it would be a fun play on words to name a project django kong, because it sounds like Djangocon, and it plays off of Donkey Kong. Then I just needed to find a way to associate Kong with what the project actually does, because it’s a Deployment Testing Tool for King/Donkey Kong sized sites :)
