Ember CLI 生成的单元测试因它存在而失败

Question

我在 controllers/order.js

中有一个订单控制器

import Ember from 'ember';

export default Ember.Controller.extend({
  needs: "orders"
});

这在/tests/unit/controllers/order-test.js

中有一个测试

import { moduleFor, test } from 'ember-qunit';

moduleFor('controller:order', {
// Specify the other units that are required for this test.
// needs: ['controller:foo']
});

// Replace this with your real tests.
test('it exists', function(assert) {
var controller = this.subject();
assert.ok(controller);
});

router.js 看起来像这样

this.resource('orders', function() {
  this.resource('order', { path: ":order_id"} , function() {
  });
  this.route('create');
});

我的想法是我有一条 /orders/ 路线，有人在 table 中点击一个订单，然后在 table 下方显示订单的更多详细信息，路线现在是 /orders/1 例如。

单元测试失败：

我需要在设置或测试中更改什么才能使单元测试通过此处？

Answer 1

您需要通知控制器依赖项的测试。为此，请将您的 moduleFor 方法更改为以下内容：

moduleFor('controller:order', {
  needs: ['controller:orders']});
