Why isn't an exception being thrown in my JUnit test?

[Dave Alvarado]

Hi,

I'm using Spring 3.1.1.RELEASE, Hibernate 4.1.0.Final, JUnit 4.8, and JPA 2.0 (hibernate-jpa-2.0-api). I'm trying to write a service test that will intentionally throw an exception, but no exception is getting thrown. I have this entity class

@Entity
@Table(name = "cb_country")
public class Country implements Serializable
{
    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    @Id
    @NotNull
    @Column(name = "id")
    /* the database id of the Country */
    private String id;

    @Column(name = "name")
    @NotNull
    /* the name of the Country */
    private String name;
	...

And I'm writing a service test where I set the name to null. But this test passes, when it should throw an exception …

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:test-context.xml" })
public class CountryServiceTest extends AbstractTransactionalJUnit4SpringContextTests
{

    @Autowired
    private CountryService m_countrySvc;
 
	…

    @Test
    public void testSaveNullName()
    {
        final Country country = new Country();
        final String id = m_testProps.getProperty("test.new.country.id");
        country.setId(id);
        country.setName(null);
        m_countrySvc.save(country);
    }   // testSaveNullName

I intentionally set the name to null, but the test goes through without throwing any errors on the save. Why isn't an exception being thrown? Here is my service class

@Service
@Transactional
public class CountryServiceImpl implements CountryService
{
   
    @Autowired
    private CountryDao countryDao;
    
    @Override
    public void save(Country country)
    {
        countryDao.save(country);
    }
	...

and here is my DAO class …

@Repository
public class CountryDaoImpl implements CountryDao
{
    @Autowired
    private EntityManager entityManager;

    @Override
    public Country save(Country country)
    {
        if(StringUtils.isEmpty(country.getId()))
        {
            entityManager.persist(country);
        }
        else
        {
            country = entityManager.merge(country);
        }
        
        return country;
    }
	...

Thanks for any advice, - Dave
