Running Spring/StrutsAssistant unit tests

I'm trying to run IDEA unit tests for the Spring and Struts plugins provided
by JetBrains.
Is there any description available on how to setup classpath/command line
arguments to run IDEA in test mode?

I can run the plugins in sandbox mode without problems, I'm looking for information
on using IdeaTestFixtureFactory/UsefulTestCase/
BasicSpringTestCase/etc.
