ERHMAGERRRD testing frameworks are so the best. Removed all our custom code for ensuring test exclusivity and doneness and isolating callbacks and everything. mocha does it all for us, and makes it pretty. Also rather than return a long chain of promises that eventually resolve to truthiness, we now use chai to make assertions about what is good and right in the world.
