为什么 jruby / selenium 断开与浏览器的连接

【问题标题】：Why is jruby / selenium dropping my connection to my browser为什么 jruby / selenium 断开与浏览器的连接
【发布时间】：2014-02-05 21:59:12
【问题描述】：

我正在进行软件升级，我的测试将开始运行时遇到问题，但突然间浏览器将停止响应，并且我得到以下堆栈跟踪：

我正在使用 cucumber (1.3.10)、gherkin (2.12.2-java)、page-object (0.9.5)、watir-webdriver (0.6.6) 和 selenium-webdriver (2.39.0)使用 Firefox 和使用 Ruby 1.9.3 的 chrome

在将 cucumber (1.2.3)、watir-webdriver(0.6.2) 和 selenium-webdriver(2.34.0) 与 ruby​​ 1.8.7 一起使用之前，我没有遇到此问题

【问题讨论】：

  • @user1177636 我完全迷路了...花了最后 3 个小时尝试调试
  • 仅供参考，发生这种情况后，我必须重新启动才能执行任何操作。
  • 您说您正在进行软件升级。这是否意味着您以前没有这个问题？解释您在此工作到停止工作之间所做的升级可能有助于确定问题。
  • @JustinKo 我更新了问题以包括以下内容：在使用 cucumber (1.2.3)、watir-webdriver(0.6.2) 和 selenium-webdriver(2.34.0) 之前我没有遇到问题) 与 ruby​​ 1.8.7.
  • 你有哪个版本的Java？您可以添加java -version 所说的内容吗？您没有可能阻止 localhost/127.0.0.1/::1 上的流量的防火墙，是吗？作为第二个疯狂的猜测，尝试强制 IPv4 over IPv6：-Djava.net.preferIPv4Stack=true

【解决方案1】：

我曾经遇到过这个问题，因为我机器上的一些其他软件阻止了 JRuby 运行这些测试。我发现当我使用 JRuby 而不是常规 Ruby 时，McAfee Host Intrusion Prevention 似乎正在断开与 Selenium 的连接。

要检查服务是否正在运行，请以系统管理员身份转到控制面板 -> 管理工具 -> 服务，然后查看 McAfee Host Intrusion Prevention 是否列为已启动。

如果是，请以管理员身份在命令提示符窗口中运行 net stop "McAfee Host Intrusion Prevention Service"。完成后运行测试，测试应该完成。
