Webdriver无法连接到Selenium服务器

Question

我目前正在尝试同时设置Webdriver和Selenium，以便通过Docker运行自动化测试，但遇到了问题。每次尝试运行测试时，都会出现以下错误ERROR wdio-runner: Error: connect ECONNREFUSED 127.0.0.1:4444

我正在使用来自docker的selenium / standalone-chrome，可以看到服务器已正确配置并以127.0.0.1:4444的速度运行。

但是，当我尝试运行webdriver时，似乎遇到了上述问题。我认为该问题一定是我的webdriver配置中存在的问题，但是按照文档操作，我看不到有什么问题...

const chai = require('chai');
const chaiWebdriver = require('chai-webdriverio').default;
const debug = process.env.DEBUG;

    global.expect = chai.expect;
  },

    if (!test.passed) {

    }
  }
