Java SE (Java Platform, Standard Edition)

Hello everyone!
I'm doing a PoC using JavaFX 2. I believe it is very important to run tests against the application logic. So I set out to do JUnit tests. I have an application using JFX Flow and need to test the presenters. I have stumbled upon a problem with the javafx.concurrent.Task. How will I be able to test my Controllers if they use the Task object?

Maven Surefire plugin gives me the following nice stacktrace:

java.lang.IllegalStateException: Task must only be used from the FX Application Thread
