Introductory guide to get PHP devs down the road to building their applications in such a way that they are easier to test using testing frameworks like PHPUnit
I've been doing php for 12 years, and I still learned a lot. This book pointed out a number of areas in which I can improve my own code & processes. Well worth reading.<p>Disclosure: I know the author, but I didn't know he was this smart ;)
It's an easy read - not something you can always say about technical books.<p>I thought it did a good job filling the gap between 'how to write automated tests' and actually writing tests for real world code.
