Vous ne voulez pas exécuter la dépendance originale (ni ses éventuelles sous‑dépendances).

À la place, vous souhaitez fournir une dépendance différente, utilisée uniquement pendant les tests (éventuellement seulement pour certains tests), et qui fournira une valeur utilisable partout où l’on utilisait celle de la dépendance originale.
