Java – hibernate JPA persistence exception

I'm trying to test my hibernate mapping based on a given set of JUnit tests However, the following tests failed

@Test
public void testEntity3Constraint() {
    expectedException.expect(PersistenceException.class);
    expectedException.expectCause(isA(ConstraintViolationException.class));

    EntityTransaction tx = em.getTransaction();
    tx.begin();
    try {
        // Entity #3
        IUplink ent3_1 = daoFactory.getUplinkDAO().findById(testData.entity3_1Id);
        ent3_1.setName(TestData.N_ENT3_2);
        em.persist(ent3_1);
        em.flush();

    } finally {
        tx.rollback();
    }
}

This is the exception I get:

Expected: (an instance of javax.persistence.PersistenceException and exception with cause is an 
     instance of org.hibernate.exception.ConstraintViolationException)
but: exception with cause is an instance of org.hibernate.exception.ConstraintViolationException cause 
     <org.hibernate.PersistentObjectException: detached entity passed to persist: dst.ass1.jpa.model.impl.UplinkImpl> 
     is a org.hibernate.PersistentObjectException

As you can see, constraint violations and persistence exceptions are exchanged in terms of instance and reason When I call entitymanager Exception thrown while persisting How can I get the expected exceptions?

I can't change the expected anomaly, and I don't want to change it I need to find a way to get the exceptions expected by the test

Thank you in advance!

Solution

You look forward to javax persistence. PersistenceException

Just change the expected exception in the test
