将量角器与Aurelia一起使用会产生错误

Question

我正在尝试使用Aurelia项目的量角器进行E2E测试。 this is my protactor.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观看时，它会在浏览器中运行该项目，当我Fyn Gulp E2e时，它给出以下错误

events.js：160 投掷er;//未经处理的"错误"事件 ^

Error: spawn C:Automated_TestingVetserve.WebsrcVetserve.Web.Apptsnode_modu

有人可以帮助我这个

Answer 1

我找到了原因，它与aurelia，node或npm无关。我错误地更新了环境变量" comspec"，而不是路径这个变量" comspec"只能保持一条路径，这是所有量角错误的真实问题
