Chris Hartjes (aka "The Grumpy Programmer") has made a name for himself in the PHP community as a big proponent of testing of all sorts in web applications. He's taking things to the next level with his own "Grumpy Learning" grouping.

As I also create more products I need a place for them all to live. I have books, and now a course I can teach and I am planning on producing screencasts for sale as well. With that in mind, I am happy to announce I have created Grumpy Learning, an umbrella site for all my training and teaching efforts to hang from.

His first book covered writing testable application, his second book looks more specifically at using PHPUnit. His latest offering is a PHP Testing Bootcamp - a three-session guided look at some of the concepts he shares not only in his books but also from his own experience (January 3rd, 10th & 17th).
