Could you maybe provide a full example of that? I tried to get this working in my own repo and in yours, using the Squid model, but got an error in both cases: Nest could not find Squid element (this provider does not exist in the current context). Much appreciated!

You can check my Colonie repo. The pvp-shield module have the in memory db, collection deletion between it and the way to get the model from the testing module.

Thanks a lot, I managed to do it! For others who might struggle: I wasn't aware of the convention for the model name to use in module.get(). It's the name property that gets passed into MongooseModule.forFeature() + the suffix 'Model' (SquidModel in this example). Apologies if this obvious, but this string is never explicitly defined as a constant or class name etc.

Oh, that's really not obvious...
I found this trick by mimicking the underlying metod of InjectModel from the nest/mongoose repo.
