Ember.js Integration tests never ends

I’m just migrating to ember 1.11 from ember 1.10 and to ember-data 1.0.0-beta19.1, but all my integration tests aren’t finishing, they keep running and never ends, that happens when a transitionTo occurs inside my route actions, but in ember 1.10 they were working. although all my unit and acceptance test to that route and action are passing, what I'm doing wrong? http://ift.tt/1GKAIej thanks
