Service injection fails in tests for ember-ajax


So I recently migrated my code from using ember-cli-ic-ajax to using ember-ajax. However, I can no longer get my tests with mocked ajax calls to work anymore. The tests are reporting at the ajax service is undefined. Anyone have any ideas?

TypeError: Cannot read property 'request' of undefined

  _favoriteRequest(resource, method) {
    return this.get('ajax').request(resource.get('links.favorite'), {
      dataType: 'json'
  ajax: Ember.inject.service(),
test('click | when resource.favorited == false', function(assert) {
  let favoriteUrl = 'http://path/to/favorite';
  let resource = Ember.Object.create({
    favorited: false,
    links: {
      favorite: favoriteUrl
  let session = {
    authorize() {
  let notify = {
    success() {
      assert.ok(true, 'notify.success was called');
  let component = this.subject({
    type: 'PUT',
    url: favoriteUrl,
    status: 204,
    dataType: 'json',
    responseTime: 1,
    responseText: []


Is this a unit test? If so, services are not injected by default. You will have to use the needs api.


Yep, it’s a unit test.


Awesome, adding needs: [ ‘service:ajax’ ] did the trick. Thanks!
