testing nodejs configurations with CircleCI

current issues

1. can't figure out why the test failures aren't consistent (not failing locally on OSX)
2. test failures doesn't cause the build to fail

[thescientist13]

One thing I noticed while debugging locally on master was that it looks like mocha is swallowing exceptions, not sure if that is an issue or not
mochajs/mocha#2797

which might explains why I couldn't find the issue of the CSS comment "breaking" the build so evidently before.

Anyway , as for the current issue here, based on the build logs, it looks like it has something to do with mocha / timeouts / exception swallowing warnings.

I might also give ava a chance, which I've had some luck with for testing webpack plugins before.
