Problème inserction des données avec JUnit

Bonjour,

Je suis en trin de réaliser une application avec spring mvc 3.
Je viens de terminer les couces dao, entites et métier (services). Maintenant, je suis en trin de faire des test unitaire pour m'assurer il n' y a pas des problème au niveau du métier avant que je passe à la couche web.

L'application génère bien les tables de la base de données mais il n'arrive pas à écrire dans la base de donnée et je ne retrouve pas l'erreur.
voici mon code:
ApplicationContext.xml:
