如何在Browserstack中使用Nightwatch.js运行并行测试

Question

使用Browserstack的Nightwatch.js的文档非常稀疏。我目前有一个用Javascript自动设置的测试，测试设置为在Browserstack上运行。它在浏览器中循环，并在不同的浏览器上重复运行测试，每次一个。如何使用Nightwatch.js在Browserstack中运行并行测试？

我想我已经正确设置了下面的settings.json，但请让我知道需要进行的更改。

此外，由于在webdriver或Browserstack的多个实例上运行测试的方法是从命令行运行：

nightwatch –e default,chrome

这是否意味着浏览器的选择仅限于浏览器名称？如果我的settings.json包含多个Firefox浏览器，每个浏览器都是不同的版本，并且在不同的操作系统上运行，该怎么办？

感谢您的帮助。谢谢

这是我的settings.json文件：

{
  "src_folders" : ["tests/"],
  "selenium" : {
    "start_process" : false,
    "host" : "hub.browserstack.com",
    "port" : 80
  },
  "test_settings" : {
    "default" : {
      "launch_url" : "http://hub.browserstack.com",
      "selenium_port"  : 80,
      "selenium_host"  : "hub.browserstack.com",
      "silent": true,
      "screenshots" : {
        "enabled" : true,
        "path" : ""
    },
"desiredCapabilities": {
  "browserName": "Firefox",
  "browser_version": "42.0",
  "os": "Windows",
  "os_version": "8.1",
  "javascriptEnabled": true,
  "acceptSslCerts": true,
  "browserstack.user": "<username>",
  "browserstack.key": "<access key>"
 }
},
  "chrome" : {
    "desiredCapabilities": {
      "browserName": "Chrome",
      "browser_version": "46",
      "os": "Windows",
      "os_version": "10",
      "javascriptEnabled": true,
      "acceptSslCerts": true,
      "browserstack.user": "<username>",
      "browserstack.key": "<access key>"
    }
},
  "ie" : {
    "desiredCapabilities" : { 
      "browserName": "internet explorer",
      "browser_version": "10",
      "os": "Windows",
      "os_version": "8",
      "javascriptEnabled": true,
      "acceptSslCerts": true,
      "browserstack.user": "<username>",
      "browserstack.key": "<access key>"
    }
  }
}

它只需要与"testrongettings"链接即可。每次实例化新浏览器时，都需要传递Browserstack的设置。

{
  "src_folders" : ["tests/"],
  "selenium" : {
    "start_process" : false,
    "host" : "hub.browserstack.com",
    "port" : 80
  },
  "test_settings" : {
    "firefox" : {
      "launch_url" : "http://hub.browserstack.com",
      "selenium_port"  : 80,
      "selenium_host"  : "hub.browserstack.com",
      "silent": true,

        "javascriptEnabled": true,
        "acceptSslCerts": true,

        "browserstack.key": "<access key>"
