Testing plugin that depends on javascript

Hi,

I'm trying to write formatter tests for my plugin that depends on javascript library, but somehow I can't get over the following exception:

ERROR: Problems found loading plugins:
<br>Plugin "JavaScript Support" was not loaded: required plugin "com.intellij.css" not installed.<br>Plugin "Oxy template support" was not loaded: required plugin "com.intellij.css" not installed.<br><br><a href="disable">Disable not loaded plugins</a><br><a href="edit">Open plugin manager</a>

Wherher I add javascript library jars or even ultimate install dir to classpath doesn't matter and the problem persists. If I remove the

 
<depends>JavaScript</depends>
from plugin.xml, the test fails because of missing javascript lib. Any help will be greatly appreciated.
