How to set unit tests using in-memory database for couchdb-nano

Looking to implement unit test coverage for nanodb functionalities for my application (with a nodejs server and couch DB) .Been doing a transition from pouchdb to nano.For the case of pouch db its possible to use 'pouchdb-adapter-memory'(Refer https://pouchdb.com/adapters.html).I was wondering if its possible to do something similar for nano where i can do unit tests but with an in memory database.Any tips/suggestions would be greatly appreciated!

No project file, test, or entry point is named. Start by reviewing Nano's testing setup and comparing the requested in-memory behavior with the referenced pouchdb-adapter-memory; done would require a clearly scoped test approach or documented limitation.
