UnreachableBrowserException：与远程浏览器通信时出错。它可能已死，而Command无法完全关闭。强行摧毁

Question

当我执行测试套件时，tearDown（）方法随机失败，并且它下面的所有测试都被跳过。以下是详细信息。屏幕快照已安装。

TESTNG跟踪：

Answer 1

此错误消息...

org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser. It may have died
.
INFO: Command failed to close cleanly. Destroying forcefully (v2). org.openqa.selenium.os.UnixProcess$SeleniumWatchDog@12c7a01b Oct 09, 2018 4:03:01 PM org.openqa.selenium.os.ProcessUtils killWinProcess WARNING: Process refused to die after 10 seconds, and couldn't taskkill it

...表示 ChromeDriver 无法杀死 WebBrowser ，即 RemoteWebDriver 。

您的主要问题是所使用的二进制版本之间的不兼容性：

根据讨论On Windows, RemoteWebDriver.quit() is always destroying forcefully?，此问题在 Selenium v​​2.45.0 之前的版本中很明显，其中@ timja2在其comment中提到：

  

它有望在Windows上更加强大地摧毁

此修补程序已通过commit 7a5e890进行了合并，预计可从 Selenium v​​2.53.1 开始使用。

解决方案

• 将硒升级到最低版本2.53.1 或当前的Version 3.14.0水平。
