We've been using PHPUnit at work for at least a year, and every time I try to find docs online how to do something or the other, I always find myself looking at the API docs tracing TestCase to Assert class, trying to decide whether I should use assertEquals() or equalTo(), and trying to become more fluent in PHPUnit's Mock interface.

As a result, I've been kicking around the idea of putting together a Cookbook-like set of pages to gather together examples of PHPUnit in action. So, I've started working on it, with the hope that you'll find it useful. Keep in mind that it's a work in progress.
