Sample Persistence Test in Spring

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = DatabaseConfig.class, loader = AnnotationConfigContextLoader.class)
public class RegistrationStatusPersistenceTests
{
    @PersistenceContext
    private EntityManager entityManager;

    @Autowired
    private RegistrationStatusRepository registrationStatusRepository;

    @Test
    @Transactional
    public void should_save_and_load() throws IOException
    {
        RegistrationStatus registrationStatus = new RegistrationStatus("New Status");

        registrationStatusRepository.saveAndFlush(registrationStatus); //Persists to database
        ((Session)entityManager.getDelegate()).evict(registrationStatus); //Evicts from cache

        //Will load from database since entity is no longer in cache
        RegistrationStatus newRegistrationStatus = registrationStatusRepository.findOne(registrationStatus.getId());

        assertThat(newRegistrationStatus.getId()).isEqualTo(registrationStatus.getId());
        assertThat(newRegistrationStatus.getName()).isEqualTo(registrationStatus.getName());
    }
}
