Spring roo and Unit Testing with Mock Objects

[camechis]

I am trying to figure out how to properly write unit tests with Spring roo generaged Entity classes. I understand how to handle the static methods on Entity objects by using the @MockStaticEntityMethods, however, what I don't understand is how to deal with persist(). Since your running in a JUNIT test the injection of the entitymanager does not occur and I don't see away to manually inject the entitymanager with a mock. Can anyone shed any light on to this if I am making any since?

What I have been doing is to use EasyMock to create a mock of the entity manager, something like this:

// easy mock
EntityManager entityManager = createMock(EntityManager.class)
entityManager.persist(eq(expected));
replay(entityManager);

// static mocks
MyEntity.entityManager();
expectReturn(entityManager);
playback();

I'd love for more people to chime in on this thread, I've found unit testing in Spring Roo to be harder than I expected.
