A coupla weeks back I was tasked with giving a presentation to the new PHP troops: an introduction to TDD. I'm not on the PHP team now, but they might need to be doing some TDD shortly, so I figured I'd at least expose them to the presentation slides if not actually take them through it. And I figured I might as well put it up for everyone to have a look at, in case it's of any use to anyone.
It's very bare bones, and I dunno how useful it'll be if I'm not there discussing each slide, but... oh well. It's here: "TDD".
If nothing else, it might solicit some questions from people, which will be a good thing.
