php|tropics Test Driven Development Presentation
Here is the Test Driven Development in PHP presentation from php|tropics. You can download either the zip or tarball flavors. In each is the PowerPoint presentation and the code files with unit tests I used when writing the presentation.
This presentation also went well. I went out on a bit of a limb and did some TDD live for about 45 minutes near the end of the session. We all decided to work on a MySQL driven Guestbook. Since there were about 30 or so people who were willing to hang around for 20 extra minutes while we finished the example up, I think that is a pretty good testament to the presentation, particularly considering the beautiful Cancun sun which was minutes away from all the dedicated attendees.
