Chris Shiflett has just posted his response to this article from Nola's blog today dealing with a simple testing class.

A few years ago, Geoff Young and I gave a talk called Testing PHP with Perl. We thought we were being funny (in our defense, those who listened to the talk seemed to agree), but I think all we did is make our project seem inaccessible to PHP developers. Perl is scary. :-)

Part of our project is a pure PHP implementation of Test::More called test-more.php. If you want to really keep things dirt simple (which seems to be Nola's goal), you can use it by itself with no framework.

He also mentions her follow up post, demonstrating how she uses the framework in her examples. He compares this with his own test-more.php, accomplishing the same things. The "test-more.php" script is included as a part of the ApacheTest package or you can grab it directly from his site...
