    Problem writing unit tests

    M Z Newbie

      Hello all.
      I was trying to write a simple unit test for Seam hotel booking example and had some troubles. Seam 1.2.1GA

      Test was the following
      @Test
      public void test_1_COMPONENT_CreateUser () throws Exception {

      EntityManagerFactory emf = Persistence.createEntityManagerFactory("bookingDatabase");
      final EntityManager em = emf.createEntityManager();

      em.getTransaction().begin();

      User user = new User();
      user.setUsername("blabla");
      user.setName("foobar");
      user.setPassword("foobar");
      RegisterAction action = new RegisterAction();
      //action.setUser(user);
      setField (action,"user",user);
      action.setEm(em);
      action.setVerify("foobar");

      action.register();

      assert action.isRegistered()==true;

      em.getTransaction().commit();
      em.close();
      }

      And I had the following exception

      javax.persistence.PersistenceException: org.hibernate.QueryException: unexpected char: '#' [select u.username from org.jboss.seam.example.booking.User u where u.username=#{user.username}]
      at org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException(AbstractEntityManagerImpl.java:567)

      but I seems, that the main cause is the following

      Also, I've tried to initialize EntityManager, like it was showed in a manual, and I had absolutelly another exception.

      When I have tried to start ready unit tests from the examples, I had also some different kind of exceptions, but, seems, they all are caused by the same.

      To show this. Icefaces had during unit testing the following:
