sfBasePhpunitSelenium2TestCase is missing

[coding-angel]

Hi there,
First i want to thanks for your efforts to make the PHP-Developers happy with your plug-in.
I just tried to use it, but there are some issues:

1. the plug-in interferes with this one from Dan Chan. After installing yours, the format providers PHP (Testing_Selenium) and PHP (PHPUnit) disappear.
   Here i suppose that adjustments in format-loader.xul are needed.

2. the parent class sfBasePhpunitSelenium2TestCase is missing?
   Would you share this class as well?
