我开发了Tour of Heroes Angular教程应用程序。之后我写了组件的测试。应用程序和组件测试都很好。现在我想用Protractor开发E2E测试，但我无法让它们运行。

每次在命令行上运行ng e2e时，我都会得到以下输出：

$ ng e2e

有关我的设置的一些有用的信息：

  • 该项目是使用Anguliar CLI
    • 创建的
  • 量角器已在全球和本地安装
  • 以下文件位于node_modules/webdriver-manager/selenium目录：chromedriver_2.32.exe, chromedriver_2.32.zip, chrome-response.xml, gecko-response.json, selenium-server-standalone-3.5.3.jar, standalone-response.xml
  • 我使用代理属性
    • 运行webdriver-manager update
  • 如果我使用正在运行的Selenium Grid或directConnect: true配置
    • 运行该命令没有任何区别
  • 浏览器已设置Chrome（Firefox有同样的问题）
  • 操作系统：Windows 10，浏览器：Chrome 51.0.2704.106 m（64位）

protractor.conf.js档案：

// Protractor configuration file, see link for more information

const { SpecReporter } = require('jasmine-spec-reporter');

这是我第一次尝试使用Angular和Protractor开发E2E测试。

感谢您的支持！

更新

如果我运行webdriver-manager update，我不知道ng e2e会被执行。所以我尝试ng e2e --no-webdriver-update并使用此命令，上面的错误不再出现了。我认为出现错误是因为没有设置代理，并且webdriver-manager无法运行更新。

但是，现在我收到了一个新错误。这是完整的输出：

$ ng e2e --no-webdriver-update

4 个答案:

答案 0 :(得分：7)

好的，我能够解决问题。这就是我所做的。

ng e2e运行webdriver-manager update命令。在我的情况下，这导致ETIMEDOUT问题，因为在没有代理的环境中，它无法下载文件。相反，我必须使用ng e2e --no-webdriver-update。

现在我遇到了Could not find update-config.json错误。

使用--proxy参数更新webdriver-manager似乎没有下载所有内容和/或更正。我必须设置环境变量HTTP_PROXY和HTTPS_PROXY并运行命令webdriver-manager update --ignore_ssl。

现在量角器正在工作。

答案 1 :(得分：4)

我发现webdriver-manager update尊重HTTPS_PROXY环境变量。尝试使用您的（公司）代理服务器HTTPS_PROXY设置http://********:80环境变量重新启动您的VS代码或命令提示符（以获取更改），您应该可以毫无问题地运行e2e测试。

答案 2 :(得分：1)

如果您使用的是Webstorm或Intellij编辑器。您可以设置HTTPS_PROXY变量，也可以在Webstorm终端中

SET https_proxy=http://yourcompanydomain.com:portnumber
SET http_proxy=http://yourcompanydomain.com:portnumber

然后在终端机中运行以下命令

ng e2e

它肯定可以工作

答案 3 :(得分：0)

就我而言，问题与公司代理人有关。 webdriver-manager update命令已超时。在.npmrc中设置代理或使用如下所示的命令行均无效。

无效的解决方案： 

SET http_proxy=http://xxx.xxxxxx.xxx:8080

SET https_proxy=http://xxx.xxxxxx.xxx:8080

有效的解决方案：：为命令提供--proxy标志：

webdriver-manager update --proxy=http://xxx.xxxxxx.xxx:8080

这是来自webdriver-manager update throwing Error: connect ETIMEDOUT
