@T4rk1n Please review.

@T4rk1n Also do you have any idea what's going wrong with the tests? If not could we look at this together on Tuesday? I've rebased on master so I have #65 already.

Please add the decorator to the method, the default exception message is not that good. 💃 when added.

There's two call to res.json(), I would save it in a variable.

This method needs the request context since it uses flask.request, there's a decorator I made to assert that.

dash-auth/dash_auth/oauth.py

Lines 14 to 22 in 70fba0d

	def need_request_context(func):
	@functools.wraps(func)
	def _wrap(*args, **kwargs):
	if not flask.has_request_context():
	raise RuntimeError('`{0}` method needs a flask/dash request'
	' context to run. Make sure to run '
	'`{0}` from a callback.'.format(func.__name__))
	return func(*args, **kwargs)
	return _wrap

Good idea, thanks for pointing that out.

I don't understand the failure this time, there's something about selenium. Let's look at it Tuesday.
