Unit Tests throw error: "Uncaught Error: Assertion Failed: BUG: Render node exists without concomitant env"

[cgrayADC]

I recently upgraded from ember 1.13.1 to ember 1.13.4 and am now getting this error on my unit tests: "Uncaught Error: Assertion Failed: BUG: Render node exists without concomitant env".

The only place I have seen any error messaging like this is here: https://github.com/emberjs/ember.js/blob/master/packages/ember-views/tests/views/view/class_name_bindings_test.js where in the final test the view's renderNode is set to null to prevent this issue.

The error is thrown for me on a component test. I have tried setting the render node to null on the component, along with messing around with the app on set up and tear down. Moving back to Ember 1.13.3 fixes the issue but I would like to be up to date if possible. Anyone know what is going on here?

I've been having a similar issue, but haven't had any luck in resolving it yet.

Here's a stack trace I have for this exact error:

Using Ember 1.13.5 and Ember-QUnit 0.4.2 this is now working for me

Had the exact same error and using Ember 1.13.5 and ember-qunit 0.4.2 also solves it for me

Closing issue because it has been fixed in qunit 0.4.2
