Mongodb – Please make sure that the argument DatabaseConnection at index [0] is available in the MongooseModule context. ShibeService Spec

I have looked the examples on Mongo testing from here:

The example tests and has mock implementations of the methods from the service but I have not got that far. I have provided the getModelToken but that does not seem to do the trick in my case.

this is the error message I receive and below are the snippets of my code:

ShibeService › should be defined

    Nest can't resolve dependencies of the ShibeModel (?). Please make sure that the argument DatabaseConnection at index [0] is available in the MongooseModule context.

    Potential solutions:
    - If DatabaseConnection is a provider, is it part of the current MongooseModule?
    - If DatabaseConnection is exported from a separate @Module, is that module imported within MongooseModule?
      @Module({
        imports: [ /* the Module containing DatabaseConnection */ ]
      })

I am only testing that the service works
