The support is very much welcomed, but Sebastian does still have one wish, though:

It would be great, though, if someone develops a free PHPUnit support for the Eclipse PHP Development Tools (PDT) project (or for vim for which there is already SimpleTest support. If you are using PHPEclipse, there is still the SimpleTest plugin for PHPEclipse that also supports PHPUnit.

You can check out the support provided for PHPUnit from these two editors by checking out these links for PHPEdit and this page for Zend Studio.
