Destructuring of Ember.testing will not work.

[rwjblue]

Ember.testing is a getter/setter in Ember, and destructuring like this will only read its value at the time the module is evaluated. In this case, Ember.testing will most likely be false when the module is evaluated, then change to true during the test. This behavior somewhat recently changed in emberjs/ember-test-helpers#227 (which is included in [email protected] / [email protected]).

I believe the fix here would be to remove the destructuring, and use Ember.testing directly inline.

const { testing } = Ember;
