Yesterday I gave a presentation on unit testing to the local PHP user-group. It went over pretty well although I had to jump around a little bit more than I would have liked. Presentation and assets are dowloadable here, or check it out locally (I did it using S5 preso framework).
The discussion afterwards was good (as always), and if you’re in the area, don’t forget that they do an informal thing at NerdBooks the Saturday after meetings. So be there and be square. :^)
