Javascript Ember.js&；QUnit:“；类型错误：对象#<；对象>；没有方法'；getHandler'&引用；拜访时

在测试中使用visit时出现错误：

TypeError:Object#没有方法“getHandler”

module("visit", {
  setup: function() {
    Ember.run(App, App.advanceReadiness);
  },
  teardown: function() {
    App.reset();
  }
});

test("visit works", function () {
  expect(2);

  // this gets executed
  equal(1, 1);

  return visit("/").then(function() {
    // this doesn't
    equal(1, 1);
  });
});

产生的错误跟踪是：

你应该去读书

使用最新的Ember，您无需运行

App.advanceReadiness

，只需在

teardown

中运行

App.reset

，在定义任何测试套件之前，您需要调用：

App.rootElement = '#qunit-fixtures';
App.setupForTesting();
App.injectTestHelpers();

一切都应该很好

让我知道下面的方法是否有效，如果有效，请给出一个我可以使用的jsbin；-）

编辑

我也不确定这会改变什么，但在他们的示例中，他们使用了

然后
而不是
然后
：

visit('/');
andThen(function(){ ... });

我需要补充的是，我正在使用Ajax调用加载我的Ember应用程序和测试代码。在检查新安装后，当将所有内容放入头部时，它可以正常工作，但是当使用Ajax获取它时，尽管在加载所有内容时手动加载并启动QUnit，但会发生此错误。因此，允许使用jQuery getScript加载Ember吗？advanceReadiness是什么？是否定义了位于根的路由，如果是的话，关联的路由/控制器/模型是什么样子的？根据Ember网站：“默认情况下，调用Ember.Application.create（）将通过调用Ember.Application.initialize（）方法自动初始化应用程序。如果需要延迟初始化，您可以调用应用程序的延迟准备（）方法。当您准备好初始化应用程序时，请调用其AdvanceRadiness（）方法。“
visit('/');
andThen(function(){ ... });
