test persistence take long time

i wish test persistence in my application, so i wrote this test using arquillian.

@RunWith(Arquillian.class)
public class FeaturesPersistenceTest {
    @Deployment
    public static Archive<?> createDeployment() {
        return ShrinkWrap.create(WebArchive.class, "test.war")
            .addPackage(Feature.class.getPackage())
            .addAsResource("test-persistence.xml", "META-INF/persistence.xml")
            .addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml");
    }

    private static final String[] FEATURE_NAME = {
        "Feature1",
        "Feature2",
        "Feature3"
    };

    @PersistenceContext(name = "testPU")
    EntityManager em;

    @Inject
    UserTransaction utx;

    @Before
    public void preparePersistenceTest() throws Exception {
        clearData();
        insertData();
        startTransaction();
    }

    @After
    public void commitTransaction() throws Exception {
        utx.commit();
    }

    private void clearData() throws Exception {
        utx.begin();
        em.joinTransaction();
        System.out.println("Dumping old records...");
        em.createQuery("delete from Feature").executeUpdate();
        utx.commit();
    }

    private void insertData() throws Exception {
        utx.begin();
        em.joinTransaction();
        System.out.println("Inserting records...");
        for (String name : FEATURE_NAME) {
            Feature feature = new Feature(name, name);
            em.persist(feature);
        }
        utx.commit();
        // clear the persistence context (first-level cache)
        em.clear();
    }

    private void startTransaction() throws Exception {
        utx.begin();
        em.joinTransaction();
    }

    @Test
    public void shouldFindAllFeaturesUsingJpqlQuery() throws Exception {

        System.out.println("Selecting (using JPQL)...");
        List<Feature> features = em.createNamedQuery("Feature.findAll", Feature.class).getResultList();

        System.out.println("Found " + features.size() + " features (using JPQL):");
        assertContainsAllFeatures(features);
    }

    /**
     * Using a separate method for assertions provides two benefits:
     *  It clearly explains what we are expecting
     *  It can be reused in other tests
     * 
     */
    private static void assertContainsAllFeatures(Collection<Feature> retrievedFeatures) {
        Assert.assertEquals(FEATURE_NAME.length, retrievedFeatures.size());
        final Set<String> retrievedFeatureTitles = new HashSet<>();
        for (Feature feature : retrievedFeatures) {
            System.out.println("* " + feature);
            retrievedFeatureTitles.add(feature.getName());
        }
        Assert.assertTrue(retrievedFeatureTitles.containsAll(Arrays.asList(FEATURE_NAME)));
    }

}

it returns greenbar, but why it write nothing in the test output nor in server output?

is it normal that it takes long time? (about 300s)
