将 Angular JS 1.4.x 更新到 Angular 2 后，Selenium 测试无法再通过 Firefox 上的 grunt-protractor-runner 运行。一旦加载 AngularJS，就会发生以下错误：

Chrome 和 Internet Explorer 工作正常。

问题出现在以下组件中：

Firefox 版本 38 和 42 grunt-protractor-runner 2.1.0 和 3.0.0（使用 selenium-server-standalone-2.48.2.jar）量角器 2.5.1 和 3.0.0

以下节点模块正在使用中（package.json）：


  "name": "...",
  "version": "1.0.0",
  "description": "",
  "main": "Gruntfile.js",
  "dependencies": 
    "jasmine-reporters": "^2.0.7",
    "protractor-video-recorder": "^0.1.0"

  ,
  "scripts": 
    "test": "echo \"Error: no test specified\" && exit 1"
  ,

Selenium 测试中没有代码部分，可以本地化产生错误。该错误仅在加载 AngularJS 时出现。

【问题讨论】：

您能在任何公共 angular2 网站上重现该问题吗？（比如说，angular.io）。谢谢。另外，你试过directConnect吗？感谢您的回答，@alecxe。我刚刚尝试过： - 针对 angular.io 进行测试可以正常工作。 - directConnect 产生完全相同的错误这是我的配置：

&gt; options:  &gt;     configFile: "....js", &gt;     args:  &gt;     	directConnect: true, &gt;         baseUrl: "...", &gt;         capabilities:  &gt;             'browserName': 'firefox', &gt;             'browser': 'Firefox' &gt;         , &gt;         specs: [ &gt;             'testFiles/....js' &gt;         ], &gt;      &gt;

感谢您的测试。因此，我们可以假设这是特定于应用程序的，并且可能与您如何引导 angular... 非常感谢！我会审查的。 【参考方案1】：
