How can i get class instance from plugin?

Hello, i am trying to build plugin for IntelliJ, my plugin is working with JUnit. Plugin need execute tests in runtime, but for running test i need to get access into project .class files, because JUnit requeries .class file for running and PSIClass is not supported. Can you help me with my problem? 

How can i get .class files from open IDE?
