更新到Angular 2后,无法在Firefox上通过Protractor运行Selenium

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

Chrome和Internet Explorer运行正常.

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(package.json):

{
  "name": "...",
  "version": "1.0.0",
  "description": "",
  "main": "Gruntfile.js",
  "dependencies": {
    "jasmine-reporters": "^2.0.7",
    "protractor-video-recorder": "^0.1.0"
  },
  "devDependencies": {
    "grunt-protractor-runner": "^3.0.0",
    "jasmine-spec-reporter": "^2.4.0",
    "lodash": "^3.10.1",
    "protractor-console": "^2.0.0"
  },
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

Selenium测试中没有代码部分,可以将其本地化以产生错误.该错误仅在加载AngularJS时出现.

为了找出问题,我安装了带有量角器的Angular 2 Go样品!并得到了完全相同的错误(在我的第一个评论)后,我改变了browserName: 'chrome'对firefox.

因此我在Protractors github页面上创建了一个新问题.
