Service injection fails in tests for ember-ajax

Testing
1

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?

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!
