Hi
I came from the Spring camp , I don't want to use Spring , and am migrating to JavaEE6 ,
But I have problem testing DAO + JPA , here is my simplified sample :
public interface PersonDao
{
public Person get(long id);
}
This is a very basic DAO , because I came from Spring , I believe DAO still have it value , so I decided to add a DAO layer .
public class PersonDaoImpl implements PersonDao , Serializable
{
@PersistenceContext(unitName = "test", type = PersistenceContextType.EXTENDED)
EntityManager entityManager ;
public PersonDaoImpl()
{
}
@Override
public Person get(long id)
{
return entityManager .find(Person.class , id);
}
}
This is a JPA-implemented DAO , I hope the EE container or the test container able to inject the EntityManager.
public class PersonDaoImplTest extends TestCase
{
@Inject
protected PersonDao personDao;
@Override
protected void setUp() throws Exception
{
//personDao = new PersonDaoImpl();
}
public void testGet()
{
System.out.println("personDao = " + personDao); // NULL !
Person p = personDao.get(1L);
System.out.println("p = " + p);
}
}
This is my test file .
OK , here comes the problem :
Because JUnit doesn't understand @javax.inject.Inject , the PersonDao will not be able to injected , the test will fail.
How do I find a test framework that able to inject the EntityManager to the PersonDaoImpl , and @Inject the PersonDaoImpl to the PersonDao of TestCase ?
I tried unitils.org , but cannot find a sample like this , it just directly inject the EntityManagerFactory to the TestCast , not what I want ...
