I am a maintainer of PouchDB - https://github.com/pouchdb/pouchdb/ https://github.com/pouchdb/pouchdb/, I probably spend more time working on the tests than any other part of PouchDB. We have a large test suite but still plenty of room to work on improving. If you were looking to work on testing then would be happy to give some guidance.
