App.reset() 在 ember-qunit 拆解时失败

Question

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();
  }
});

其中一个正在抛出错误： Uncaught TypeError: Cannot read property 'length' of null

这可以追溯到我的marketplace_search_spec.js 文件中的App.reset() 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在控制器init 中调用_super 引起的，我覆盖了我的ArrayController。

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