Tests unitaire sous springboot avec mockito

Version imprimable

Hello,

Je débute dans le dev Java et je tente sans succès de réaliser un test.
J'ai des erreurs sur les méthodes "when" et "thenreturn " qui me disent :

Citation:

The method "when" and "thenReturn"(Player) is undefined for the type PlayerPronoTest

sachant que " PlayerPronoTest " est le nom de la classe de mes tests unitaires

Voici mon code

d'ailleurs c'est mieux pour cet exemple de supprimer l'implémentation du repository ( PlayerRepositoryImpl.java ) car ça illustre la force de Mockito qui instancie un Mock a partir de l'interface.
