Sebastian Bergmann has officially announced the creation of a new planet in the PHP community - one specifically for the PHPUnit testing suite - Planet PHPUnit.   At the moment only three feeds are aggregated on Planet PHPUnit: release announcements, articles about new features in PHPUnit written by myself, and Manuel Pichler's blog postings on phpUnderControl.   He also is requesting that anyone out there currently writing on any topics surrounding the popular unit testing framework send him an email letting him know where it's at.
