@edsilv are there some specific targeted pieces that you think should be tested?

[edsilv]

I think the ideal thing could be to have an actual nodejs implementation of an auth server, and to make requests against that locally when running the test suite to test the auth utils.

We could potentially use something like passport.js to create access tokens and simulate a successful user interaction login via twitter/whatever?

It sounds great to have that entire functionality tested. Would it be ok to start from a simpler place though for the manifesto test suite that gets us closer to a release?

#58 Just adds some basic tests around Utils. I look at a more comprehensive approach also.

Sure, sounds good.
