@matthewringer why is the return not necessary anymore?

[codydaig]

@ilanbiala According to #254, it's returning a promise and calling .done() in which they claim causes issues with Mocha. I have not yet experienced this, but can see what might be happening.

@ilanbiala as @codydaig mentioned returning the promise and calling .done() which raises an exception with Mocha. There is a more extensive description of the problem in the original issue, and here is an instance of the same issue from Mocha's repo.

Let me know if you have any other questions.

@codydaig LGTY?
