Mike Lively has taken a big step in his PHP development process, a move to using unit tests for his resulting code. In this new blog post he describes the experience - mainly how much he's enjoying it.
I have spent alot of time in testing using SimpleTest and I have also given some time to test-more.php. However, up until just recently I had honestly never used PHPUnit before. The big motivational factor for me (other than to try something new) was to see how the code coverage feature was coming along.
I would have to say that after a few weeks of tinkering with it I am impressed.
He mentions some of the notable features he's used as well as some of his surprisng finds along the way:
Using the framework is an absolute breeze and there is excellent documentation [...]. The most impressive part of this experience in my mind was how runnable the software is straight out of CVS.
