Testing front end code with browserify and mocha/chai

In order to test first run grunt browserify:test which will create the test-suite.js file from all of the .js files located in test/front-end/unit. After that open test.html in a browser and there should be two passing tests. To run tests on the command line run grunt test, this will build the same test-suite with browserify and run grunt-simple-mocha on that file.
