javascript - Ember.js＆QUnit: “TypeError: Object #<Object> has no method ' getHandler'”调用访问时

在测试中使用访问时出现错误:

TypeError:对象＃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);
  });
});

产生的错误跟踪为:

我已经确保按照this answer的建议在运行测试之前加载了Ember。 QUnit也可以正常运行，因为灯具的基本测试正在运行。

我现在已经在这个问题上花费了数小时，而且我不知道为什么会这样。

编辑(跟随丹尼尔的评论)
路线非常简单，看起来像这样:

App.IndexRoute = Ember.Route.extend({
  redirect: function(){
    this.transitionTo('about');
  }
});
App.Router.map(function(){
  this.route('about');
});

最佳答案

你应该去读http://emberjs.com/guides/testing/integration/

使用最新的Ember，您不需要运行App.advanceReadiness，只需运行App.reset中的teardown，并且在定义任何测试套件之前，您需要调用:

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

一切都应该正常工作。

Lemme知道遵循此方法是否不起作用，如果可以，请给我一个jsbin； ;-)

我也不确定这会改变什么，但是在他们的例子中，他们使用的是andThen而不是then:

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