I had suggested in an email to the CakePHP mailing list that an interactive console for doing testing of Models would be good. While at php|tek I spent a lot of time with the CakePHP guys talking about this. Out of it came some more ideas (like the ability to test your routes) and they even implemented a console that spits out API information for you. Very cool stuff. So, I decided to do a little screencast demo of a very early alpha version of the interactive console.
The screencast shows Chris running a test on his own classes, including demonstrating the built-in help the app offers.
