How to avoid caching of entites in Spring Repository during a Transaction for tests

Question

I have a Test like this:

@Transactional
@Test
public void addRemoveTest() {
    MyEntitiy entity = new MyEntitiy ();

    entity = textureRepository.saveAndFlush(entity );
    TestTransaction.flagForCommit();
    TestTransaction.end();
    TestTransaction.start();
    final MyEntitiy loadedTexture = myEntityRepository.findOne(entity .getId());
}

This works perfectly fine. But when I remove the Committing code for the transaction, the repository will not call the database when calling findOne(). Can I somehow force it to make the database call for my tests?

I prefer my test to not commit any transaction.

I'm not able to get the Session to clear the cache. And I'm not even sure if clearing the session would help.

The only way I know is to call entityManager.clear() before calling the finder. I think you can autowire the EntityManager into your test:

@Autowired
private EntityManager entityManager;

Your test would then look like this:

@Transactional
@Test
public void addRemoveTest() {
    MyEntitiy entity = new MyEntitiy ();

    entity = textureRepository.saveAndFlush(entity );
    entityManager.clear();
    final MyEntitiy loadedTexture = myEntityRepository.findOne(entity .getId());
}
