Chromedriver从116升级到117后远程运行Selenium测试报错

问题描述 #

在虚拟机环境中，使用Selenium WebDriver 3.141.0配合chromedriver 117.0.5938.88执行自动化测试时出现连接强制关闭错误，切换至chromedriver 116时无此问题，且本地环境运行相同测试完全正常。

解决方案 #

• 版本兼容性适配：Selenium 3.141.0发布时间较早，对Chrome 117及对应chromedriver的支持存在适配缺陷。建议升级Selenium至4.x版本，新版对高版本ChromeDriver的兼容性更完善。
• 虚拟机网络排查：检查虚拟机的防火墙、杀毒软件是否拦截了ChromeDriver与WebDriver之间的本地端口连接，可临时关闭防护工具验证问题是否解决。
• 添加启动参数：初始化ChromeDriver时添加--no-sandbox和--disable-dev-shm-usage参数，规避虚拟机环境下的沙箱限制与内存共享问题。示例代码：

var chromeOptions = new ChromeOptions();
chromeOptions.AddArgument("--no-sandbox");
chromeOptions.AddArgument("--disable-dev-shm-usage");
IWebDriver driver = new ChromeDriver(chromeOptions);

• 版本一致性检查：确认虚拟机中Chrome浏览器版本与chromedriver 117.0.5938.88完全匹配，版本不匹配会导致通信异常。
