Test EJB & JPA avec Arquillian & Testg / Wildfly

Question

Je suis en difficulté avec une analyse de test assez simple à l'aide d'Arquillian - il utilise une classe EJB dans l'ordre d'insérer une entité (utilisateur) à la DB à l'aide de JPA (hibernate), mais une exception est lancée.J'utilise Testng comme cadre de test.

Structure de dossier

MyProject  
   ear
   domain - all jpa entities  
   ejb - holds NewUser ejb  
   war - currently empty

test

public class NewUserTest extends Arquillian
{
    @EJB
    private NewUser newUser;

    @Deployment
    public static JavaArchive createDeployment()
    {
        JavaArchive arc = ShrinkWrap
                .create(JavaArchive.class)
                .addClasses(User.class, Gender.class, PersonalData.class,
                        NewUser.class, NewUserTest.class)
                .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml")
                .addAsResource("META-INF/test-persistence.xml",
                        "META-INF/persistence.xml");
        return arc;
    }

    @Test
    public void checkDBInsert()
    {
        newUser.registerUser();
    }
}

ejb

@Stateless
public class NewUser
{
    @PersistenceContext(name = "testPU")
    EntityManager em;

    public void registerUser()
    {
        Calendar cal = Calendar.getInstance();
        cal.set(1111, 2, 3);
        User user = new User("Bugs", "Bunny", Gender.MALE, cal.getTime());
        em.persist(user);
    }
}

entité

@Entity
@TableGenerator(name = "UserIdGenerator", initialValue = 0, allocationSize = 1)
@NamedQueries({
        @NamedQuery(name = "User.findAll", query = "SELECT u FROM User u")})
public class User implements Serializable
{
    private static final long serialVersionUID = -5675781058185805901L;

    @Id
    @GeneratedValue(strategy = GenerationType.TABLE, generator = "UserIdGenerator")
    private Long id;

    @Embedded
    PersonalData personalData;

    public User()
    {
    }

    public User(String name, String familyName, Gender gender, Date birthdate)
    {
        this.init(name, familyName, gender, birthdate);
    }

    public Long getId()
    {
        return this.id;
    }

    public void setId(Long id)
    {
        this.id = id;
    }

    public PersonalData getPersonalData()
    {
        return this.personalData;
    }

    public void setPersonalData(PersonalData personalData)
    {
        this.personalData = personalData;
    }

    private void init(String name, String familyName, Gender gender,
            Date birthdate)
    {
        PersonalData personalDataToAdd = new PersonalData(name, familyName,
                gender, birthdate);
        this.init(personalDataToAdd);
    }

    private void init(PersonalData personalData)
    {
        this.personalData = personalData;
    }

    @Override
    public boolean equals(Object other)
    {
        boolean toReturn = false;

        if (other instanceof User)
        {
            User castOther = (User) other;
            toReturn = this.personalData.equals(castOther.getPersonalData());
        }

        return toReturn;
    }

    @Override
    public String toString()
    {
        return "Id: " + this.id + "\n" + this.personalData;

Peu importe ce que je change, je reçois une autre exception ...

Answer 1

Apparemment, j'ai eu deux test-persistance.xml: un dans les ressources de domaine (le bon) et l'autre dans les ressources de l'EJB (une mauvaise).Lorsque vous avez déplacé le test-persistant de domaine .xml aux ressources de l'EJB tout a fonctionné.
