端到端测试期间的错误 1

Question

我正在做一个角度练习，我必须进行 e2e 测试，当我运行量角器 protractor.conf.js 时出现以下错误：

[launcher] Running 1 instances of WebDriver
(node:3032) [DEP0022] DeprecationWarning: os.tmpDir() is deprecated. Use os.tmpdir() instead.

谁能帮我找出问题所在？

我附上了 protractor.conf.js 文件和包含我在应用程序上执行的所有 e2e 测试的文件：

exports.config = {
  allScriptsTimeout: 11000,
  specs: [
    'e2e/*.js'
  ],
  capabilities: {
    'browserName': 'chrome'
  },

  baseUrl: 'http://localhost:3001/',

  framework: 'jasmine',
  directConnect: true,

  jasmineNodeOpts: {
    defaultTimeoutInterval: 30000
  }
};

'use strict';

describe('conFusion App E2E Testing', function() {
  //Introduce the tests into this file
  it('should automatically redirect to / when location hash/fragment is empty', function() {
    browser.get('index.html');
    expect(browser.getLocationAbsUrl()).toMatch("/");
  });

  //Set up a simple test for the index file to check if the page title is set correctly
  describe('index', function() {
    beforeEach(function() {
      browser.get('index.html#/');
    });

    it('should have a title', function() {
      expect(browser.getTitle()).
      toEqual('Ristorante Con Fusion');
    });
  });

  //We will navigate to the first menu item, and test a few properties there
  describe('menu 0 item', function() {
    beforeEach(function() {
      browser.get('index.html#/menu/0');
    });

    it('should have a name', function() {
      var name = element(by.binding('dish.name'));
      expect(name.getText()).
      toEqual('Uthapizza Hot $4.99');
    });

    it('should show the number of comments as', function() {
      expect(element.all(by.repeater('comment in dish.comments'))
        .count()).toEqual(7);

    });

    it('should show the first comment author as', function() {
      element(by.model('critiria')).sendKeys('author');
      expect(element.all(by.repeater('comment in dish.comments'))
        .count()).toEqual(7);
      var author = element.all(by.repeater('comment in dish.comments'))
        .first().element(by.binding('comment.author'));

      expect(author.getText()).toContain('25 Cent');

    });
  });



});

出于以下原因，我再次添加并安装了 Chromedriver Web 版本 2.19 Chrome 44版，总是报错：

您正在使用：

• Chrome 驱动程序 2.19 版
• Chrome 版本 59

这两个不兼容 - 你需要ChromeDriver 2.30 to work with Chrome 59:

最新版本：ChromeDriver 2.30

支持 Chrome v58-60

更新您的 ChromeDriver。 通常通过以下方式完成：

webdriver-manager update
