Testing with nestjs-firebase

[ygordanniel]

Hi folks,

I'm new to NestJS testing and I was wondering how would I go about testing my app.

When I try to run a unit test I'm getting: Nest can't resolve dependencies of the PetsService (?). Please make sure that the argument "FIREBASE_TOKEN" at index [0] is available in the RootTestModule context..

Here is my PetService constructor.

constructor(@InjectFirebaseAdmin() readonly firebaseAdmin: FirebaseAdmin) {
  this.collection = firebaseAdmin.firestore.collection(this.petsCollection);
}

Is there a way to mock that dependency injection?
