Marcus Baker has released SimpleTest version 1.0! Download the files here and view the API documentation here. Congratulations Marcus, this is a fine work and an outstanding contribution to the PHP community.
For anyone who has not caught testing fever, try it out. There has been no other programming practice which has positively affected my programming practices the way unit testing and test driven development have.
I alluded to my in progress book in an earlier post. Each of the examples in the book was developed with unit testing coverage using SimpleTest, and all of these tests will be available in the source code download for the book. I hope the book shows good coding practices as well as demonstrating design patterns in PHP.
