Unable to embed EntityManager in JPA integration testing with Arquillian and WildFly

I am trying to do integration testing with the following stack:

App server: Embedded WildFly
CDI container: Weld
Database: In-memory H2
ORM: Hibernate/JPA
Platform: Java 8
OS: Mac OS X 10.10

I installed basic integration testing with Arquillian (as done here ), and I can embed dependencies, but injection EntityManagerproves to be a problem. When dereferencing a field, the object manager always appears NullPointerException.

I have seen many articles (including this and this ), but I still cannot get this seemingly simple thing to work.

Please see below my pom.xml

Test version

@RunWith(Arquillian.class)

  @PersistenceContext
  private EntityManager em; // Null pointer.

  public GreeterTest() {
  }

  @Deployment

  }

  @Test
  public void testPersistence() {
    DummyEntity de = new DummyEntity();
    de.setId(1l);
    de.setName("Petr Cech");
    de.setAge(10);
    em.persist(de);

    Query q = em.createQuery("SELECT d.age FROM DummyEntity d");
    assertEquals(10, q.getResultList().get(0));
  }
}

The full Maven project is available on GitHub .

Please, what am I doing wrong?
