When testing Ember code, without putting expectations in a Ember.run callback, you'll get this error:

Failure/Error: Assertion Failed: You have turned on testing mode, which disabled the run-loop's autorun. You will need to wrap any code with asynchronous side-effects in an Ember.run

The error recommends wrapping expectations in Ember.run:

describe 'something', ->
  it 'does something', ->
    Ember.run ->
      expect(1).to.eql(1)

Ember.run is noisy and adds no value to test comprehension, so we can remove it by controlling the runloop manually.

In spec_helper.coffee:

Ember.testing = true
beforeEach -> Ember.run.begin()
afterEach -> Ember.run.sync()
