save_and_open_page with ember-cli?

I have a background in developing applications with Ruby on Rails, where I use Capybara and Rspec to render the output of what Poltergeist "sees".

I'm just starting out with Ember and was writing my first acceptance test when I really started to miss that feature. Is there a way to render the html generated at a certain point in the acceptance test with ember-cli? What would I have to do to set it up?
