错误的 wdio.webapp.conf.js 配置或 chrome 驱动程序问题 - 自动测试未启动

如何解决错误的 wdio.webapp.conf.js 配置或 chrome 驱动程序问题 - 自动测试未启动

由于某种原因，我无法开始使用 WebdriverIO 和 Mocha + Chai 测试框架编写的测试。当我运行 yarn start 命令来启动它们时，每次测试都会得到这样的输出：

这就是 wdio.webapp.conf.js 的样子：

global.downloadDir = path.join(process.cwd(),'test/data/downloads');

global.uploadPermDir = path.join(process.cwd(),'test/data/uploadsPerm');
global.baseUrl = 'https://drive.automation.com/';

        }
    },afterTest: async function (test,context,{ error,result,duration,passed,retries })  {
        if (!passed) {

        removeDirContents(global.uploadDir);

};

我已经尝试过什么？

• 在我的电脑上重新安装 Chrome 浏览器。
• 安装/重新安装各种库，如 wdio、selenium-standalone 等。
• 使用管理员模式从 CMD 运行测试。
• 将二进制值设置为 C://Program Files//Google//Chrome//Application//chromedriver.exe
• 将节点降级到 12.8.1 版本

我还能尝试什么来使它们工作？

解决方法

yarn add @wdio/selenium-standalone-service 

解决了这个问题。
