BDD style tests with Mocha + Chai

[nathanboktae]

I'm finding it a bit hard to read the tests - are you interested in having them rewritten with Mocha + chai? they should be alot more readable and mocha-as-promised may help here too.

Also, Grunt isn't doing much either, but that's a bit different.

er, by "are you interested" i mean I'll do it and submit a PR if you are 🍺

I like mocha and chai too. but i'm not good at chai now. :'(
And I love grunt and I'm using it for most of my projects but this is too small to grunt.
your pull request would be welcomed anytime.
let me close this issue :)
