// A simple JS unit test to demonstrate the system.
//
// Note that you can run this test simply by running
//
//   ./node_modules/.bin/grunt test
//
// But if you want to have Karma run continuously and rerun
// tests when it sees file change then you can run Karma
// directly and pass in the --no-single-run flag:
//
//  ./node_modules/.bin/karma start --no-single-run
