A good testing framework for CI

[eluser]panos konstantinides[/eluser]
Hello all, for the past few days I've been looking for a good testing framework for CI. I am interested in testing all of the MVC components, although the main effort will concentrate on Models and Controllers. Basically I am looking for something like JUnit for CI, for those familiar with Java.

I have tried a few of them (I especially like TOAST: http://jensroland.com/projects/toast/) and all of them have their pros and cons. I would appreciate any suggestions for a testing framework that I could use to test CI (please do not suggest CI's Unit Testing Class, I find it poor for what I'm trying to do). I wouldn't mind even a commercial solution.

Regards

Panos
