使用GeckoDriver和Firefox时无法联系：java.nio.channels.ClosedByInterruptException

标签： java selenium firefox selenium-webdriver geckodriver

我正在运行测试： 硒3.11 Geckodriver v0.20.1 TestNG 6.9.8 Linux OS上的Firefox 57

我有10个套房，每个套房有10-30个班级。总持续时间约为16小时。 Webdriver在beforeClass中创建，并在afterClass中退出（使用driver.quit（））。

当我使用Chrome驱动程序运行测试时，一切正常，所有套件都完全执行。

但是如果我将驱动程序切换到Firefox驱动程序，则只执行3-4或5个套件，然后我收到以下错误：

Cannot contact : java.nio.channels.ClosedByInterruptException
Can't take a screenshot: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:14191

它出现在不同的步骤和操作中，测试只是定期进行 出现此错误：

我的问题是：在哪里查找以及添加什么来调试信息以调查发生这种情况的原因？

1 个答案:

答案 0 :(得分：1)

此错误消息...... 

Cannot contact : java.nio.channels.ClosedByInterruptException
Can't take a screenshot: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:14191

...意味着当一个线程在另一个线程在通道上的I / O操作中被阻塞时中断它时，接收到已检查的异常。

ClosedByInterruptException类

ClosedByInterruptException是一个已检查的异常，当一个线程在一个通道上的I / O操作中忙/阻塞时中断另一个线程时引发该异常。在抛出此异常之前，通道必须已关闭。

值得一提的是，通道操作几乎与执行I / O操作的线程绑定。如果此线程中断，则由于IO安全问题，流或通道将关闭。

您的代码试验会给我们提供更多关于出错的提示但是从错误堆栈跟踪中可以明显看出，主要问题之一是版本之间的不兼容您正在使用的二进制文件如下：

  • 虽然您使用的是 Selenium v​​3.11.0 ，但 JDK 似乎 v1.8.0_45 ，这已经相当旧了。

解决方案

  • 将 JDK 升级到最近的级别JDK 8u171。
  • 将 Selenium 升级到当前级别Version 3.12.0。
  • 将 GeckoDriver 升级到GeckoDriver v0.20.1级别。
  • 确保GeckoDriver出现在指定位置。
  • GeckoDriver拥有非root用户的可执行权限。
  • 将 Firefox 版本升级至 Firefox v60.0.1 级别。
  • 通过 IDE 清理您的项目工作区，仅使用所需的依赖项重建项目
    • 。
  • 使用CCleaner工具清除执行 Test Suite 之前和之后的所有操作系统杂务。
  • 如果您的基本 Web客户端版本太旧，请通过Revo Uninstaller将其卸载并安装最新的GA和已发布的 Web客户端版本。
  • 进行系统重启。
  • 以非root用户身份执行Test。
  • 始终在driver.quit()方法中调用tearDown(){}以关闭＆amp;正常销毁 WebDriver 和 Web客户端实例。

琐事

如果 AUT（正在测试的应用程序）是一个多线程应用程序，您应该查找可能会中断在该通道上执行IO操作的线程的interrupt()调用。如果它是一个Web应用程序或其他类型的托管环境，其中线程管理不适用于您的应用程序（如Servlet / EJB容器），您应该查找线程安全违规。另一个需要关注的地方是应用程序关闭或使用线程池时（Servlet / EJB容器！）。然后要注意池大小的动态管理！
