Is there any way to create an XML file that contains entities to be used to load the EntityManager with and run unit tests.  We want to create a "mock" situation where we can run unit tests without have a DB present.  We want to create an XML file that contains the data for the tests, load it into a disconnected EntityManager, run our tests and check the results.

Some additonal data on this.
 
I have been able to serialize OUT to XML an instance of one of my Entity based classes.  But the Deserialization fails with a Null Object Reference.  Below is the exception. It looks like it is failing trying to find the EntityGroup for the object being created.  Yet where was no group when it was serialized.  It was created in code without an entity manager or group
