How to run unit tests

• Run the ember test server: ember test --server
  • This will monitor for changes to the source or the test and run them automatically.
• Hint: Add &nocontainer=hidden to testem results viewer to get rid of nasty white div: http://localhost:7357/8986/tests/index.html?module=NavMenuComponent&nojshint=true&nocontainer=hidden

Troubleshooting

• in order to troubleshoot some strange failures use recommendations from the Ember debugging page. Particularly, for promises add the following in the test-helper.js

import { assert } from '@ember/debug';
import RSVP from 'rsvp';

RSVP.on('error', function(error) {
  assert(error, false);
});
