Как запустить nightwatch.js в соуснике для локального URL

Question

Я хочу запустить проверку автоматизации Nightwatch вaucelab для локальных URL-адресов, но не хочу запускать sauceconnect в отдельном терминале.

Я попробовал это, и вот мои файлы nighwatch.json и nightwatch.config.js код:

Код файла nightwatch.json:

{
  "src_folders" : ["tests"],
  "output_folder" : "reports",
  "custom_commands_path" : "custom_commands",
  "custom_assertions_path" : "",
  "page_objects_path" : "",
  "globals_path" : "",

  "test_settings" : {
    "default" : {
      "launch_url" : "http://localhost",
      "selenium_port"  : 80,
      "selenium_host"  : "ondemand.saucelabs.com",
      "silent": true,
      "screenshots" : {
        "enabled" : false,
        "path" : ""
      },
      "username" : "${SAUCE_USERNAME}",
      "access_key" : "${SAUCE_ACCESS_KEY}",

      "skip_testcases_on_fail": false,

      "desiredCapabilities": {
        "javascriptEnabled": true,
        "acceptSslCerts": true
      }
    },

    "chrome": {
      "desiredCapabilities": {
        "platform": "Windows 7",
        "browserName": "chrome",
        "version": "latest"
      }
    },

    "firefox" : {
      "desiredCapabilities": {
        "platform": "Windows 8",
        "browserName": "firefox",
        "version": "33"
      }
    },

    "internet_explorer_edge" : {
      "desiredCapabilities": {
        "platform": "Windows 10",
        "browserName": "MicrosoftEdge",
        "version": "latest"
      }
    },

    "android_s4_emulator": {
      "desiredCapabilities": {
        "browserName": "android",
        "deviceOrientation": "portrait",
        "deviceName": "Samsung Galaxy S4 Emulator"
      }
    },

    "iphone_6_simulator": {
      "desiredCapabilities": {
        "browserName": "iPhone",
        "deviceOrientation": "portrait",
        "deviceName": "iPhone 6",
        "platform": "OSX 10.10",
        "version": "8.4"
      }
    }

  }
}

Вот моя ночная часы.config.js код файла:

const sauceConnectLauncher = require('sauce-connect-launcher');

module.exports = (function (settings) {
  let sauce;
  let launcher;


  const closeSauce = () => new Promise((resolve, reject) => {
    try {
      sauce.close(resolve);
    } catch (e) {
      console.log(e)
    }
  });

  const openSauce = () => {
    if (!launcher) {
      launcher = new Promise((resolve, reject) => {
        sauceConnectLauncher({
          "username" : "${SAUCE_USERNAME}",
          "access_key" : "${SAUCE_ACCESS_KEY}",
        }, ((err, process) => {
          console.log("Started Sauce Connect Process");
          sauce = process;
          err && reject(err);
          !err && resolve(process);
        }));
      });
    }
    return launcher.then(() => {
      return cb();
    });
  };

  const catchError = (e) => console.log(`e`, e);

  settings.test_settings.default.globals = {
    before: (done) => {
      Promise.resolve()
        .then(() => (
          openSauce()
        ))
        .then(done)
        .catch(catchError);
    },
    after: function (done) {
      Promise.resolve()
        .then(() => (
          closeSauce()
        ))
        .then(done)
        .then(() => process.exit(0))
        .catch(catchError);
    }
  };
  return settings;
})(require('./nightwatch.json'));

Но я получил ошибку ниже:

Я попробовал это в первый раз, и я не знаю точный процесс, может кто-нибудь одинукажи мне точный процесс.
