I have a java application with Hibernate as ORM. Now is time to test the application. I want to use Junit (I used time ago and I thought I knew how its works :s). The first problem I find is creating an instance of a DaoImpl class where the method which retrieve data is (and I want to test this method). The error I got doing "new" is: java.Lang.ExceptionInitializerError. I think its come because of the class of the instance has Hibernate classes, try to connect to the DataBase and so on... and probaly I cannot create a instance of this class as easy because of hibernate in back.

If this, can annyone give a reference to configure for junit works with Hibernate. I find Hiberante with Spring. Is not valid to me because spring is not implemented in my application.

thanks all!!

More in detail the exactly problem is:

@Test
public void testBuscaTramitesPorAgrupacion(){
// dao = new EstadisticasDAOImpl();

Session session = HibernateUtil.getSessionFactory().openSession(); "Line throw exception"
Criteria criteria = session.createCriteria(UsuarioLogin.class);
List<UsuarioLogin> listaUsuarios = null;

When test reach the line where session is created its thrown this exception:
java.lang.ExceptionInInitializerError

Its compile fine. Its in runtime when fails.

The test folder is within the project with hibernate libraries are and DaoImpl classes to make query does.

It was my fail ^_^

The connection to the DB was looking for the hibernate.properties which is in the Apache project. Just copying this file to the test folder of the propel project it works fine.

You can close the thread.

Thanks anyway!!
