org.openqa.selenium.remote.UnreachableBrowserException: 与远程浏览器通信时出错。它可能已经死于 ChromeDriver 和 Selenium
org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser. It may have died with ChromeDriver and Selenium
我每小时 运行 一堆测试用例使用 selenium-java 3.12.0；测试NG；硒与 docker，詹金斯。
有时（大约十分之一）我收到错误消息：

您的代码试验会对调试问题有所帮助。也许您的主要问题可能是以下之一：
- 您提到您正在使用 selenium-java 3.12.0 但您的错误跟踪日志提到了 selenium-java 3.6.0。因此可能在这个 项目 中引用了多个 selenium-java 实例。所以你需要确保你的 project 只配置了一组 selenium-java 二进制文件。
根据最佳实践：
- 将 Selenium 升级到当前级别 Version 3.14.0。
- 将Chrome驱动程序升级到当前ChromeDriver v2.41级别。
- 保持Chrome版本在Chromev66-68[=89=之间] 水平。 (as per ChromeDriver v2.41 release notes)
- (WindowsOS only) 使用CCleaner工具擦除前后的所有OS杂事执行您的测试套件。
- (LinuxOS only) Free Up and Release the Unused/Cached Memory in Ubuntu/Linux Mint 测试套件[=93]执行前后=].
- 如果您的基础 Web 客户端 版本太旧，则通过 Revo Uninstaller 卸载它并安装最新的 GA 和发布版本的 Web 客户端.
正如你所提到的运行每小时一堆测试用例可能有多个悬空实例ChromeDriver和Chrome可以通过进程列表查看（LinuxOS) 或 TaskManager (Windows OS)。您需要始终在 tearDown(){} 方法中调用 driver.quit() 以优雅地关闭和销毁 WebDriver 和 Web Client 实例。
如果 WebDriver 和 Web Browser 的悬空实例仍然存在，请考虑用蛮力杀死它们。您可以在
