-Tests are written in [Mocha](http://mochajs.org/) and run in Node, [PhantomJS](http://phantomjs.org/), and a variety of browsers with [Zuul](https://github.com/defunctzombie/zuul) and [Open Sauce](https://saucelabs.com/opensauce/). All PRs should be accompanied by unit tests, with ideally one feature / bugfix per PR. Code linting happens with [ESLint](http://eslint.org/) automatically post-test.

+* `$ npm run coverage` - print the coverage report of the last test run
+* `$ npm run coverage:html` - generate an html report for the last test run
 * `$ npm run lint` - lints code
-* `$ npm run test` - runs Node unit tests
 * `$ npm run test:watch` - runs unit tests and re-runs on changes
 * `$ npm run test:browser` - runs tests in a local browser
 * `$ npm run test:sauce` - runs tests in Sauce Labs on multiple browsers
