Ember.js testing focusOut

Quick note how to test focusOut in integration tests in ember.
I was writing signup form using easyForm with client side validations. Note that validations return a promise so we have async call. The feature was about displaying error when I leave field.
First I wrote this and it worked on local machine. But then on CI I started getting errors after running this again it occurs that it fails sometimes.

	test 'Signup form', ->
	click('input[name="businessName"]')
	fillIn('input[name="businessName"]', "Some name")
	click('input[name="contactName"]')
	andThen ->
	ok(find("div.businessName span.help-block.error").is(':visible'), "Should see error message on previous field")

The solution was to invoke the blur even on element instead of going to another field.  Click helper is a async helper(http://emberjs.com/guides/testing/test-helpers/#toc_asynchronous-helpers) but it's probably waiting only for click event, not the corresponding ones.

	Ember.Test.registerAsyncHelper 'leaveBusinessName',
	(app, name, context) ->
	triggerEvent('input[name="businessName"]', 'blur')
	test 'Signup form', ->
	click('input[name="businessName"]')
	fillIn('input[name="businessName"]', "Some name")
	leaveBusinessName()
	andThen ->
	ok(find("div.businessName span.help-block.error").is(':visible'), "Should see error message on previous field")
