I’m trying some code.
It is an architecture Hibernate – JPA – Spring. For now, I will wish to run it in a JUnit test.
For moment, i have some exception :
GRAVE: Caught exception while allowing TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@6295eb] to prepare test instance [test.service.UserAccountServiceTest@609959]

Any idea ?
Thanks a lot !!
I didn’t find the solution.
In Maven, it is not working.
In dynamic web project, i succeed to execute my test if i change the @PersistenceContext to an EXTENDED.
