=================================================================================

Works fine on 6.0.1. This broke our app on upgrading to 6.1.0 and a colleague (@jeffhertzler) and I reproduced it in minimal format.

[ndekeister-us]

It looks like that a change is needed on this line -> https://github.com/ember-cli/ember-exam/blob/master/index.js#L23

Tested on your project which is using mocha

let options = {
  exclude: ['ember-mocha', 'mocha', 'ember-qunit', 'qunit']
};

Works fine (your app build, test run correctly), tested same code on a project using ember-qunit > 5 and it is working fine

I guess that an additional check need to be done here

• if project is using ember-mocha then options.exclude should be set to ['ember-mocha', 'mocha', 'ember-qunit', 'qunit']
• if project is using ember-qunit < 5.0.0-beta.1, then options.exclude should be set to ['ember-mocha', 'mocha', 'ember-qunit']
• if project is using ember-qunit > 5.0.0-beta.1, then options.exclude should be set to ['ember-mocha', 'mocha', 'ember-qunit', 'qunit']

Not sure about the why, will try to take some times to better understand it and, in that case, suggest a PR

ping @robertpbaxter if you wanna try #699

this PR fixes the issue on the codebase @robertpbaxter was referring to
