Test-infected? Kind of

I've been spending increasing amounts of time recently getting to grips with Unit Testing and the Test-Driven "way". It can be hugely satisfying, but more often than not I'm finding it painfully frustrating. Don't get me wrong, I know it's the right way to go about things, I don't need any convincing. I did some growing up in public thanks to the lovely Advanced-PHP folks at Sitepoint, but I'm not there yet.

The best fully Test-Driven code I've managed so far is PHPTuring, and I'm trying to rewrite Briolette using TDD, but it's slow going. (If anyone of any talent is interested in helping develop a TDD MVC framework in PHP5, I'd be interested to hear from you).
