Je suis en train d'essayer de développer un service web, le service web fonctionne et je suis en train d'implémenter des tests arquillian.

Mon installation semble être fonctionnelle, avec des tests sur des classes sans @Inject je n'ai pas de difficultés, toutefois sur cet example j'ai l'erreur suivante qui arrive.
