Ive only played with PHPUnit for a week now, but I have found out that…
PHPUnit3 (to be released) supports code coverage, also using Xdebug. PHPUnit2 might, but it doesnt show up when typing, "phpunit –help" at the command line. So far, this tool has been great for creating unit tests. The reporting abilities, and compatibility with Phing looks very impressive.
