I need help understanding why my test is failing.

I'm trying to unittest a persist method for persisting a user. The involwed classes are :

PersistenceManager (singleton for sharing a entitymanagerfactory app wide)

UserControler ( subclass of jpa entity User )

UserActions (junit testclass)

The problem I have is that when I get a entitymanager in the unittest and ask if it contain the just persisted user it returns false.

See below relevant code:

Well,

I resolved the issue, my unittest is passing when i use the find instead of contains.



So that give us a new question:

Given the following scenario:
- jpa persistence with hibernate and H2 transactions configured "resource_local"
- Class A sharing a entityManagerFactory
- Class B getting a entityManager with class A factory and persisting an object Foo

if in a class C we get a entityManager with class A factory and query for Foo:
- contains return false
- find returns object foo as expected.

Can somebody explain what i'm missing to understand here?
