As of Ember 2.17 the Ember.Test.adapter is not required to have an exception method, and the method essentially has no purpose. The default implementation (in the Ember.Test.QUnitAdapter) is to re-throw, but that is exactly what happens by default.

This removes "yet another magical testing thing", and relies on both Ember and QUnit's default behaviors to ensure that tests properly fail when unhandled RSVP rejections occur.

Cross linking (again) emberjs/ember.js#15871.

Should probably wait for the tests added around unhandled rejections in #306.

Its effectively public, its basically in the same state as wait was before. Lots of folks use it, but we haven't officially said its "public".

I'll open a PR to export it from the entry point...

// method When `exception` is not present, the unhandled rejection is
// automatically re-thrown and will therefore hit QUnit's own global error
// handler (therefore appropriately causing test failure)

this condition sounds like it would only work for 2.17, but I'm assuming the same is true for 2.18?

hasEmberVersion is basically like semver.gte for the provided major + minor.
