Testing Python API which uses MongoDB

Im working on a Python API which uses MongoDB and Flask-PyMongo. My APP gets the MONGO_URI (also on testing).

I don't want to use the production database on software tests. I want a mongo container which i can start with python before the test starts or just a library which can mock the pymongo library.

Im on a windos platform, most existing libraries which i found doesn't work properly. I already tested mockupdb and InstantMongo.

On APIs with SQL i can use in-memory SQLite in tests and in production i can use the regular SQL server. Is there a similar approach for MongoDB? (I have to use mongodb and can't switch to sql)
