Testing

[eluser]parrots[/eluser]
I have a fairly large application in CI right now, and I'm looking to improve our test procedures. And by "improve" I mean "put some in place". Looking to see how some other developers out there go about it.

I was thinking of leveraging the Unit Testing framework within CI for some of the more basic stuff -- making sure models do what they are supposed to, etc. But this only takes care of at best half(?) of what really needs to be tested since a lot of logic always resides in the controller. I was considering an automated web test suite (to record my actions through the site and be able to play them back and check conditions) but the products out there seem very lacking.

Aside from a massive set of test procedures that someone has to manually go through, how do you guys deal with regression testing and the likes on a large site?
