Can you think of a way we can mimic having different drivers and setting them to verify that this works?
Would deep cloning the driver, modify some arbitrary property, then setting it, and asserting that getting the driver, we'll have the arbitrary property be enough testing?
Otherwise, LGTM.

nitpick: why do we need a one time variable? We could directly pass it to MongooseError

Better readability IMO. Easier to break up the long message if there's a temporary variable rather than putting it as a param.

Summary
Right now overwriting the Mongoose driver is a bit messy, because 1)
ConnectionandCollectionaren't changed when you domongoose.driver.set(), and 2) driver is always global, so no way to have 2 Mongoose instances with the same driver in the same process.Examples
You can now do
mongoose.setDriver()without any extra work to use a different driver.
