Yep, could certainly do that. I wanted to be specific about the 'pruneBefore' and 'now' rather than what is in the config file, but I guess the values in the config file will also be fine (or I'll make them fine for this test). I could add a 2nd test so that we test both the stored procedure and then `db.pruneTokens()` so if either or both fail it'll be easier to see what has gone wrong.
