Right on the heels of Derick Rethans' post of the first release candidate for Xdebug 2, Sebastian Bergmann has announced a beta release of his unit testing package - PHPUnit 3.

A list of features is available as well as a list of changes. You can install PHPUnit using the PEAR Installer. Note that previous installations of the PHPUnit and PHPUnit2 packages from the pear.php.net channel have to be uninstalled.

Sebastian also mentions the PHPUnit Pocket Guide published a little while back, acting as the official documentation for the project.
