Sebastian Bergmann quickly notes the support that's been added to Parabuild for PHPUnit:

Viewtier Systems is looking for testers of their new support for PHPUnit in their Parabuild software build and release management system. I am excited that a company such as Viewtier Systems realizes that there is a market for their product in the PHP space and adapts their tool to work well with existing tools such as PHPUnit in that space.

Parabuild is a software build and release management system that helps software teams and organizations reduce risks of project failures by providing Continuous Integration and delivering practically unbreakable nightly builds.

If you would like to sign up as a beta tester, all of the information is here.
