我所有的 ember-qunit 测试都有类似的设置：

moduleFor('route:marketplace-search', 'Marketplace Search route', {
  setup: function() {
    setFixtures();
  },
  teardown: function() {
    App.reset();
  }
});

其中之一是抛出一个错误： Uncaught TypeError: Cannot read property 'length' of null

这可以追溯到App.reset()我的marketplace_search_spec.js文件中的行：

任何想法为什么我看到这个失败？

正如@AmielMartin 指出的那样，我的问题是由于没有调用我_super在.initArrayController

App.MarketplaceSearchController = Ember.ArrayController.extend({
  init: function() {
    this._super();
    // Do stuff here
  }
});
