使用Ember 2.7.0在验收测试中模拟服务

对于旧版本的ember,this is the accepted answer for mocking a service in an acceptance test

使用Ember 2.7.0,我无法按照上面的答案调用startApp。 但是,经过一些快速测试,这似乎在注入服务时效果很好。

import Ember from 'ember';
import { module, test } from 'qunit';

let speakerMock = Ember.Service.extend({
  speak: function() {
    console.log("Acceptance Mock!");
  }
});

module('Acceptance | acceptance demo', {
  beforeEach: function() {
    // the key here is that the registered service:name IS NOT the same as the real service you're trying to mock
    // if you inject it as the same service:name, then the real one will take precedence and be loaded
    this.application.register('service:mockSpeaker', speakerMock);

    // this should look like your non-test injection, but with the service:name being that of the mock.
    // this will make speakerService use your mock
    this.application.inject('controller', 'speakerService', 'service:mockSpeaker');
  }
});

test('visit a route that will trigger usage of the mock service' , function(assert) {
  visit('/');

  andThen(function() {
    assert.equal(currentURL(), '/');
  });
});

我错过了什么吗?我怀疑:

a)为什么没有记录?余烬docs provide excellent documentation on stubbing services in components

b)是否因为在验收测试中模拟服务而不鼓励?为什么呢?

验收测试用于测试用户交互和应用程序   流。测试以与a相同的方式与应用程序交互   用户可以通过填写表单字段和单击来执行操作   纽扣。验收测试确保项目中的功能   基本上是功能性的,并且在确保核心方面很有价值   一个项目的功能没有退化,并且该项目的目标   正在接受。

没有“明确”提及,但我理解“验收测试与实际应用程序的行为相同”。所以你不应该嘲笑某事。
