ember-sinon-qunit is incompatible with ember-qunit 8.0.1

[lozjackson]

after upgrading ember-qunit to 8.0.1 I get the following error when trying to run the tests for our app

Uncaught Error: QUnit has already been defined.

I've tried reproducing this in a fresh ember app - ember-qunit 8.0.1 works until I installed ember-sinon-qunit (7.1.4).

@lozjackson @elwayman02 I bet this is caused by #891

[ndekeister-us]

Had same error when migrating to Ember 5, which install ember-qunit v8

Created #914 which solved the issue on my side, didn't investigated deeper on why we have this error now

[elwayman02]

#908 and #905 appear to have fixed the problem, but we'll keep this ticket open until the next release so we can confirm the issue is resolved.

can't wait!! thanks for the hard work

[elwayman02]

Please test 7.4.0 and let me know if the issue is resolved!

[ndekeister-us]

7.4.0 fixed the issue on my side, tests are running when we use it with ember-qunit@8

Thanks 🎉

[elwayman02]

That's fantastic! Great work, everyone.

[lozjackson]

can confirm the issue is fixed for me after upgrading to 7.4.0.

Thanks

Just in case anyone else stumbled upon this issue from Google search: I was still seeing this issue after upgrading to 7.4.0.

After a long search, it turns out there was one test file located inside of the app folder. This caused qunit to be imported by ember-auto-import. Moving that to the test folder fixed the issue.
