How can I run Ember integration tests using Testem?

I’m playing around with the new integration testing and the ember-testing package. I’ve also been using lineman for a development environment with Ember that I can completely separate from Rails.

I’d really like to know how to run my integration tests in Testem though… I keep gettting the following error and can’t for the life of me figure it out.

Unable to add "ember-application" class to rootElement. Make sure you set rootElement to the body or an element in the body.


Were you able to make it work? I’m thinking about trying testem after some time using karma and I would be interested in your findings, if you could share them.

Nah I gave up :slight_smile:

Just swapping to use rails-qunit.

I got this working today. Config below…

window.App = Ember.Application.create({rootElement:'.js-new-desktop-experience'})

testem.json (I use lineman, so this would be my “config/spec.json” instead):

  "framework" : "qunit",
  "launch_in_dev" : ["PhantomJS"],
  "launch_in_ci" : ["PhantomJS"],
  "test_page" : "spec/testem.html"
