First blog. The responsibility is almost too much. Was trying to convince Sitepoint to call this “Harry’s Hot Tip of the Day” to lower expectations but they weren’t having it. See they’ve got Simon over there so I’d better shape up.
Want to know about Test Driven Development? Try here. The author is Marcus Baker, aka lastcraft and a regular on Sitepoint’s Advanced PHP forums. He’s also the brains / fingers behind Simple Test which, IMO, is the unit test framework for PHP. We’ve been using it extensively in WACT and additional upfront effort of writing tests is already paying off.
