Question

我正在使用Ember-cli和qunit进行测试。

项目模型

import DS from 'ember-data';
var attr = DS.attr,
    belongsTo = DS.belongsTo;

export default DS.Model.extend({
  offer: belongsTo('offer'),
});

这里添加了关于item和Offer模型之间关系的测试。

项目测试

import Ember from "ember";
import DS from "ember-data";
import { test, moduleForModel } from 'ember-qunit';

moduleForModel('item', 'Item Model', {
  needs: ['model:item']
});

test('offer relationship', function() {
  var relationships = Ember.get(App.Item, 'relationships');
  deepEqual(relationships.get(App.Offer), [
    { name: 'offer', kind: 'belongsTo' }
  ]);
});

错误追踪：

我错过了什么吗？

我现在正处于将旧的Ember应用程序转换为新的ember-cli并遇到类似情况的过程中。由于Ember CLI使用ES6模块语法，因此无法直接在App对象上访问任何内容。

您需要从各自的模型文件中导入对象。

import Item from "<modulePrefix>/models/item";
import Offer from "<modulePrefix>/models/offer";

其次，你的moduleForModel（'item'）应该有：['model：offer']。

这是使用提供的文件传递测试。（我用过：ember new stackoverflow）

import Ember from "ember";
import { test, moduleForModel } from 'ember-qunit';
/* Import Models */
import Item from "stackoverflow/models/item";
import Offer from "stackoverflow/models/offer";

moduleForModel('item', 'Item', {
  // Item needs the offer model.
  needs: ['model:offer']
});

test('offer relationship', function() {
  /* For some reason this was necessary to prime the store. */
  /* Without this line I get the error:  
     'undefined' is not an object (evaluating 'store.modelFor') */
  var model = this.subject();

  /* App.Item -> Item, App.Offer -> Offer */
  var relationships = Ember.get(Item, 'relationships');
  deepEqual(relationships.get(Offer), [
    { name: 'offer', kind: 'belongsTo' }
  ]);
});
