Chris Shiflett has a new post over on his blog today with his looking into a method of unit testing for PHP using various Apache testing products, including SimpleTest or Apache-Test.

I've been answering questions lately on the SitePoint forums - PHP, Advanced PHP Programming, and Web Security.

One topic really caught my attention - How many actually use unit testing?. No, it wasn't the grammatical error that caught my eye but rather the fact that unit testing was being discussed on a PHP forum.

While reading the topic, I realized that there were many PHP developers using SimpleTest. Feeling like the black sheep, I mentioned my admiration for Apache-Test.

He then points us to some research and a demo that he and Geoff Young (of modperlcookbook.org) created to use the Apache-Test functionality to beat on PHP applications as well...
