When I do Ember.Component.Create() in an unit test for mixin i get this error. I was upgrading ember from 1.13 to 2.10, this test worked fine in 1.13 but in 2.10 I get this error. Looks like in 2.10 ember component init requires an app instance.

Few things I have tried:
To startApp() in setup and destroy, similar to integration testi ng
To override init but init always requires _super() to be called
Tried to execute in integration testing environment where application is created
I tried to do renderer: this.render or other options but nothing worked, finally based on the lead I got here
I did renderer: {} and it worked just fine.
There are other good solutions in the link too but its not needed in my scenario since I am not rendering anything.
