Integration test module my composite stats show

class Test.MyCompositeStatsShowTest extends IntegrationTestSuite
  # URL to load for ALL our tests
  url: '/'
  # Ajax mock groups to be used
  ajaxMockGroupNames: ['basic']


  # simple test with only one Ember run loop
  test_show_basic: ->
    @assertSame find('#some-element').length, 1, "the my composite stats show element should be present"


  # Advanced test with many Ember run loop. Each run loop will wait that the bindings are resolved and that there is no
  # more stuff waiting or running
  # The first argument of each run loop (called here `mb`) is a message bus object which you can use to pass stuff from
  # one run loop to another. Here are its predefined properties:
  # - `mb.arguments` contains the arguments the test has received
  # - `mb.previousResult` contains the result of the previous run loop
  # - `mb.merge(object1, object@, ...)` can be used to add multiple property to the message bus object at once
  # - `mb.extract('prop1 prop2 prop3')` (or `mb.extract('prop1', 'prop2', 'prop3')`) can be used to extract some
  #   properties of the message bus object as another object
  # If a string is given instead of a function, it'll be interpreted as an URL to visit. The string can also begin with '@'
  # in which case the URL will be read from the given property of this test suite
  test_show_advanced: [
    # first run loop
    (mb) ->
      mb.controller = controller('myController')
      mb.controller.send 'someAction'

    # second run loop
    (mb) ->
      @assertTrue find('#some-element').hasClass('someClass'), "the element should have the correct class"
      @assertSame mb.controller.get('length'), 10, "there should be 10 items after someAction"
