Apparently PHP has quality assurance. That is to say, there are a team of contributers dedicated to QA for PHP. One of the members, Zoe Slattery from IBM gave a talk here today with the superb name “test||die”.

Anyone who has compiled PHP from source should be aware that there is a test suite for PHP, but fewer are likley to know that it is actively maintained.

All the tests use standard PHP, so if you know PHP, you can contribute tests. Check out qa.php.net for more information. (I didn’t even know that website existed).
