Clicking remove button - acceptance tests

[snewcomer]

Having trouble clicking the remove button for multiple inputs in my acceptance tests. This change came after the 0.9.0 release. I guess I am trying to understand the reason why my basic css selectors of clicking the dropdown, selecting an option and removing an option don't work anymore (it seems dispatchEvent is req'd). I have to use the test helpers, which are great, but don't know the why. Maybe a bit of an explantion or thoughts on a solution to the above would be greatly appreciated. Maybe some insight could help me in perhaps getting a new test helper in there as well! Thanks!

This is an issue with ember 2.4 that is fixed in ember 2.5+.

The problem is that Ember's acceptance helpers fired jquery events (not native events) until this PR.
This is fundamentally wrong, since jquery event's do not trigger events added with addEventListener.
Events added as element properties onclick={{action "foo"}} are also busted since, unless you call preventDefault on them, they are considered unhandled and will fire twice.

Using Ember 2.5-beta should also be fine. If you are using the helpers provided by the addon (p.e selectChoose) you're fine because I already take care of the details of how events are fired, although there is no test-helper for removing events in multiple selects.

I'd accept one test helper for that tho.

In integration tests I use a couple helpers to fire native. I don't advertise them because I don't think most people need them, but if you find them useful, take a look to them: https://github.com/cibernox/ember-power-select/blob/master/test-support/helpers/ember-power-select.js#L13-L35
