[FIXED] Testing Hibernate Envers

Issue

I would like to write tests about revision. In the console I see the update call of Hibernate, BUT no insertions into AUD-Table.

Test-Method:

@DataJpaTest
class JPAHistoryTest {

    @Test
    public void test() {
        def entity = // create Entity
        def entity2 = // create same Entity
        entity2.setPrice(entity2.getPrice() + 10)
        entity2.setLastUpdate(entity2.lastUpdate.plusSeconds(10))

        service.save(entity)
        service.save(entity2)
        repository.flush() // Hibernate updates changes

        assert repository.findRevisions(entity.id).content.empty == false // FAIL!
    }
}

My Entity looks like:

@Entity
@Audited
class Entity {
    @Id @GeneratedValue Long id
    @Column(nullable = false) BigDecimal price
}

Thank you very much.

Solution

As I found out I keep the @DataJpaTest and add @Transactional(propagation = NOT_SUPPORTED) to make sure, the test methods will not start a transaction. Because if they would run in a transaction, then the envers history entries will be written, when the test close the transaction.

@RunWith(SpringRunner)
@DataJpaTest
@Transactional(propagation = NOT_SUPPORTED)
class JPAHistoryTest {
    @After
    void after() {
        repository.deleteAll()
    }

    @Test
    public void testTwoInsert() {
        def entity1 = // ...
        def entity2 = // ...

        sut.save(entity1 )
        sut.save(entity2 )

        assert repository.findRevisions(entity1.id).content.size() == 1
        assert repository.findRevisions(entity2.id).content.size() == 1
    }
}
