Using the `wait` helper in Ember integration tests

Component integration tests are a powerful way to test your Ember components in relative isolation. They look something like this:

test('it renders', function(assert) {  
  assert.expect(2);

  this.render(hbs`{{x-foo}}`);

  assert.equal(this.$().text().trim(), '');
});

Sometimes, however, you'll want to handle a bit of asynchrony. Thanks to rwjblue that is now not too big of a deal with the wait helper:

import { moduleForComponent, test } from 'ember-test-helpers';  
import wait from 'ember-test-helpers/wait';

test('it works when async exists in an event/action', function(assert) {  
  this.render(hbs`{{my-foo}}`);

  this.$('button').click();

  return wait()
    .then(() => {
      // assertions for after async behavior
    });
});

And that's about it! You'll need to update ember-qunit to at least: v0.4.15

Cheers!
