Have Geek Brain

Testing task

I am new to Java EE 6 and I am trying to develop a very simple JAX-RS application. RESTfull webservice is working fine. However, when I ran the test application, I got the following. What have I done wrong? Or will I forget any configuration? Of course I am creating JNDI and I am using Netbeans 6.8 IDE. In conclusion, thank you for your consultation.

My essence:


@Entity
@Table(name = "BOOK")
@NamedQueries({
    @NamedQuery(name = "Book.findAll", query = "SELECT b FROM Book b"),
    @NamedQuery(name = "Book.findById", query = "SELECT b FROM Book b WHERE b.id = :id"),
    @NamedQuery(name = "Book.findByTitle", query = "SELECT b FROM Book b WHERE b.title = :title"),
    @NamedQuery(name = "Book.findByDescription", query = "SELECT b FROM Book b WHERE b.description = :description"),
    @NamedQuery(name = "Book.findByPrice", query = "SELECT b FROM Book b WHERE b.price = :price"),
    @NamedQuery(name = "Book.findByNumberofpage", query = "SELECT b FROM Book b WHERE b.numberofpage = :numberofpage")})
public class Book implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @Basic(optional = false)
    @Column(name = "ID")
    private Integer id;
    @Basic(optional = false)
    @Column(name = "TITLE")
    private String title;
    @Basic(optional = false)
    @Column(name = "DESCRIPTION")
    private String description;
    @Basic(optional = false)
    @Column(name = "PRICE")
    private double price;
    @Basic(optional = false)
    @Column(name = "NUMBEROFPAGE")
    private int numberofpage;

    public Book()
    {
    }

    public Book(Integer id)
    {
        this.id = id;
    }

    public Book(Integer id, String title, String description, double price, int numberofpage)
    {
        this.id = id;
        this.title = title;
        this.description = description;
        this.price = price;
        this.numberofpage = numberofpage;
    }

    public Integer getId()
    {
        return id;
    }

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

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public int getNumberofpage() {
        return numberofpage;
    }

    public void setNumberofpage(int numberofpage) {
        this.numberofpage = numberofpage;
    }

    @Override
    public int hashCode() {
        int hash = 0;
        hash += (id != null ? id.hashCode() : 0);
        return hash;
    }

    @Override
    public boolean equals(Object object) {
        // TODO: Warning - this method won't work in the case the id fields are not set
        if (!(object instanceof Book)) {
            return false;
        }
        Book other = (Book) object;
        if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
            return false;
        }
        return true;
    }

    @Override
    public String toString() {
        return "com.entity.Book[id=" + id + "]";
    }
}

My Junit testing class:


public class BookTest
{

    private static EntityManager em;
    private static EntityManagerFactory emf;

    public BookTest()
    {

    }

    @BeforeClass
    public static void setUpClass() throws Exception
    {
        emf = Persistence.createEntityManagerFactory("E01R01PU");
        em = emf.createEntityManager();
    }

    @AfterClass
    public static void tearDownClass() throws Exception
    {
        em.close();
        emf.close();
    }

    @Test
    public void createBook()
    {
        Book book = new Book();
        book.setId(1);
        book.setDescription("Mastering the Behavior Driven Development with Ruby on Rails");
        book.setTitle("Mastering the BDD");
        book.setPrice(25.9f);
        book.setNumberofpage(1029);

        em.persist(book);

        assertNotNull("ID should not be null", book.getId());
    }
}

My persistence.xml 


<persistence>
  <persistence-unit name="E01R01PU" transaction-type="JTA">
    <jta-data-source>BookstoreJNDI</jta-data-source>
    <properties />
  </persistence-unit>
</persistence>

And the exception:

First, you are missing some JARs in your classpath and my suggestion is to add $GF_HOME/modules/gf-client.jar

(don't copy the JAR into your project, don't point directly to it).

Second, your test will not pass in its current state, it will skip some parts:

  • persist

    needs to be called inside a transaction
  • you need flush

    to make changes to get the assigned id.

Here is an improved version that will run each test method with its own EntityManager

and inside a transaction (which is rolled back at the end of the test method):



public class BookTest {
    private static EntityManager em;
    private static EntityManagerFactory emf;

    @BeforeClass
    public static void createEntityManagerFactory() {
        emf = Persistence.createEntityManagerFactory("E01R01PU");
    }

    @AfterClass
    public static void closeEntityManagerFactory() throws Exception {
        emf.close();
    }

    @Before
    public void beginTransaction() {
        em = emf.createEntityManager();
        em.getTransaction().begin();
    }

    @After
    public void rollbackTransaction() {
        if (em.getTransaction().isActive()) {
            em.getTransaction().rollback();
        }

        if (em.isOpen()) {
            em.close();
        }
    }

    @Test
    public void createBook() {
        Book book = new Book();
        book.setId(1);
        book.setDescription("Mastering the Behavior Driven Development with " +
                            "Ruby on Rails");
        book.setTitle("Mastering the BDD");
        book.setPrice(25.9f);
        book.setNumberofpage(1029);

        em.persist(book);
        em.flush(); // sync the in-memory changes with the db
        // now this will pass
        assertNotNull("ID should not be null", book.getId()); 
    }
}

Bonus: this test will pass :)

Please note that people generally prefer to be able to run tests without having to run the container, i.e. without using JNDI. Here is an example persistence.xml

showing how to set up EclipseLink to connect to a server-mode Derby database that you can use in a testing context:

You first have a "Caused by: java.lang.ClassNotFoundException: com.sun.gjc.spi.ResourceAdapter" error in your output. This should be the first thing you should fix (something is missing). On the other hand, I see so many annotations in you that are unnecessary in most cases. Specifically for column names. BTW: Why are you commenting out attributes instead of getters? You have overwritten equals () but haven't actually implemented it (only for the Id field, but what about other fields?). And if you need to overwrite equals, you have to overwrite hashCode Let the IDE create them much easier.
