This is some minimal boilerplate to get started with test-driven development using Karma, Mocha, and Chai. It uses Grunt to watch for file changes and re-run tests automatically.
Clone this project, then run npm install to install dependencies.
Then run grunt test. This will begin watching files within the app/ and test/ directories for changes. When there are file changes to any of the js files inside either directory, the tests inside the test/ directory will be run.
The boilerplate is set up to only run tests in Chrome. If you'd like to add more browsers, that option is available in karma.conf.js.
