Testabilité des EJB 3.1 (Un cas simple : Hello World !)
Bonjour,
voilà un simple EJB HelloWorldService sur le que quel je veux faire un simple test unitaire. (IDE utiliser NetBeans 7.0.)
Et Donc le test devrait consister à vérifier que la méthode sayHelloWorld() de HelloWorldService renvoie bien « Hello World ».
EJB HelloWorldService :

import javax.ejb.Local;
import javax.ejb.Stateless;
@Stateless
@Local
public class HelloWorldService implements IHelloWorldService
{
@Override
public String sayHelloWorld() {
return "Hello World";
}
} |
Pour tester uniquement cet EJB j'ai crée un test JUnit qui se charge d’instancier l’EJBContainer et de récupérer notre Bean. Le seul et unique test sera de vérifier que l’appel à la méthode sayHelloWorld retourne bien « Hello World ».

Quelqu'un pourrait-il m'expliquer ce qui ne va pas ?
j'ai aussi des doute avec les chemin "target/classes.ext" et "java:global/classes.ext/" que je comprend pas vraiment ces quoi normalement d’après ce que j'ai lu il préciser le répertoire des classes compilées. (si je doit les changer comme je doit le faire ?)
Mais sa na rien avoir avec le message d'erreur.
Merci d'avance pour votre aide.
