需要Model的Ember测试初始化器

Question

我有一个初始化器，它从页面上的脚本标记中的JSON对象向应用程序注册一些模块。在应用程序中工作正常，但测试失败，因为它无法找到预期的模型。

initialzers/bootstrap-payload.js

export function initialize(container, application) {
  var store = container.lookup('service:store'),
    payloadKeys = Object.keys(BOOTSTRAP_DATA);
  payloadKeys.forEach((key) => {
    var registryKey = `bootstrap-payload:${key}`,
        model;
    model = store.createRecord(key, BOOTSTRAP_DATA[key]);
    application.register(registryKey, model, {instantiate:false});
  });
}
export default {
  name: 'bootstrap-payload',
  after: 'ember-data',
  initialize: initialize
};

测试/初始化/bootstrap-payload-test.js

import Ember from 'ember';
import { initialize } from '../../../initializers/bootstrap-payload';
import { module, test } from 'qunit';
var registry, application;
module('Unit | Initializer | bootstrap payload', {
  needs: ['model:channel'],
  beforeEach: function() {
    Ember.run(function() {
      application = Ember.Application.create();
      registry = application.registry;
      application.deferReadiness();
    });
  }
});
// Replace this with your real tests.
test('it works', function(assert) {
  initialize(registry, application);
  // you would normally confirm the results of the initializer here
  assert.ok(true);
});

tests/index.html中包含一个示例BOOTSTRAP_DATA变量，其中包含一个始终期望存在的模型，称为channel。当运行ember test时，我得到以下错误:

at http://localhost:7357/assets/test-support.js:5604: No model was found for 'channel'

我如何注入这个依赖，needs字段似乎不工作在这种情况下。或者有什么方法可以让初始化器更易于测试?

感谢https://github.com/taras。

与其为这个初始化式创建一个单元测试，不如创建一个验收测试来断言这些属性已经被正确地注入到容器中。

import Ember from 'ember';
import { module, test } from 'qunit';
import startApp from 'test-models-in-initializer/tests/helpers/start-app';
import Channel from 'test-models-in-initializer/models/channel';
var application;
module('Acceptance | index', {
  beforeEach: function() {
    window.BOOTSTRAP_DATA = {
      'channel': {
        'id': 0,
        'name': 'Test Channel',
        'internalName': 'test-channel',
        'logoUrl': '//somecdn.net/test-channel/logo.png'
      }
    };
    application = startApp();
  },
  afterEach: function() {
    Ember.run(application, 'destroy');
  }
});
test('channel type', function(assert) {
  let channel = application.registry.lookup('bootstrap-payload:channel');
  assert.ok(channel, "is registered");
  assert.ok(channel instanceof Channel);
});
