We use mocha and chai and sinon and sinon-chai for testing our EmberJS applications.
If you have functionality that needs to be tested by changing form elements directly (e.g. $(".class").val('hello')) but requires asynchronous behaviour, such as updating the underlying Ember model, you can use andThen(function) to chain these asynchronous events:
describe 'interface', ->
it 'can change the underlying model', (done) ->
@timeout 5e3 # set timeout to 5s
# visit the application root
visit '/'
Ember.run ->
expect(find(".date-input")).not.to.be.empty
expect(find(".time-type")).not.to.be.empty
# defaults
expect(find(".time-type").val()).to.equal("")
expect(find(".date-input").val()).to.equal('original')
# now change
$(".time-type").val('change')
$(".time-type").change() # trigger on('change'), this will update model.date-input
andThen ->
# should now have changed
expect(find(".date-input").val()).to.equal('updated')
done()
