Title: TestCase with TestBean inner-class
The use of an inner-class annotated as an EJB can get you all the resources
you may need to run your test case such as a UserTransaction,
EntityManager, JMS Topic or Queue, DataSource, references to other EJBs,
etc.  

Simply add a *META-INF/ejb-jar.xml* to your *test* *sources* and start
annotating your inner class as needed. 

The test logic can be placed inside the inner-class EJB or you can setup
the EJB to pass the required resources to the outer class.
