You can use Ming which has an in-memory mongo db pymongo connection replacement.

import ming
mg = ming.create_datastore('mim://')
mg.conn # is the connection
mg.db # is a db with no name
mg.conn.somedb.somecol
# >> mim.Collection(mim.Database(somedb), somecol)
col = mg.conn.somedb.somecol
col.insert({'a': 1})
# >> ObjectId('5216ac3fe0323a1218f4e9aa')
col.find().count()
# >> 1
