Protractor 使用带有Aurelia的量角器会产生误差

我正在尝试为aurelia项目使用量角器进行e2e测试。

这是我的proactor.conf.js

exports.config = {
  directConnect: true,

  // Capabilities to be passed to the webdriver instance.
  capabilities: {
    'browserName': 'chrome'
  },

  //seleniumAddress: 'http://0.0.0.0:4444',
  // add proper version number
  seleniumServerJar: './node_modules/gulp-protractor/node_modules/protractor/selenium/selenium-server-standalone-2.44.0.jar',
  specs: ['test/e2e/dist/**/*.ts'],

  plugins: [{
    path: 'aurelia.protractor.js'
  }],


  // Options to be passed to Jasmine-node.
  jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 30000
  }
};

这是demo.spec.ts

import {PageObject_Welcome} from './welcome.po';
import {PageObject_Skeleton} from './skeleton.po';

describe('aurelia skeleton app', function() {
  let po_welcome: PageObject_Welcome;
  let po_skeleton: PageObject_Skeleton;

  beforeEach( () => {
    po_skeleton = new PageObject_Skeleton();
    po_welcome = new PageObject_Welcome();

    browser.loadAndWaitForAureliaPage("http://localhost:9000");
  });

  it('should load the page and display the initial page title', () => {
    expect(po_skeleton.getCurrentPageTitle()).toBe('Welcome | Aurelia');
  });

  it('should display greeting', () => {
    expect(po_welcome.getGreeting()).toBe('Welcome to the Aurelia Navigation App!');
  });

  it('should automatically write down the fullname', () => {
    po_welcome.setFirstname('Rob');
    po_welcome.setLastname('Eisenberg');

    // For now there is a timing issue with the binding.
    // Until resolved we will use a short sleep to overcome the issue.
    browser.sleep(200);
    expect(po_welcome.getFullname()).toBe('ROB EISENBERG');
  });

  it('should show alert message when clicking submit button', () => {
    expect(po_welcome.openAlertDialog()).toBe(true);
  });

  it('should navigate to users page', () => {
    po_skeleton.navigateTo('#/users');
    expect(po_skeleton.getCurrentPageTitle()).toBe('Github Users | Aurelia');
  });
});

当我运行gulp watch时，它会在浏览器中运行项目，当我运行gulp e2e时， 它给出了以下错误

events.js:160 投掷者；//未处理的“错误”事件 ^

---

有人能帮我解决这个问题吗？

我已经找到了原因，它与aurelia、node或npm无关。我错误地更新了环境变量“comSpec”，而不是PATH

---

这个变量“comSpec”只能保存一条路径，这是所有量角器错误的真正问题

您得到的错误是文件

C:\Automated\u Testing\Vetserve.Web\src\Vetserve.Web.Appts\node\u modu es\.bin\dragrator.cmd不存在。它存在吗？是的，它存在there@thebluefox我删除了一些at标记，因为如果存在“%~dp0\node.exe”（“%~dp0\node.exe”“%~dp0\..\dragrator\bin\dragrator”%*）或其他（SETLOCAL SET pathText=%pathText:；.JS；=；%node“%~dp0\..\dragrator\bin\dragrator”%*）则不允许发布注释
