运行Selenium测试时随机UnreachableBrowserException异常 [英] Random UnreachableBrowserException when running Selenium tests

问题描述

我发现，当运行我的硒测试时，我在控制台中收到错误.....但是这些错误在每次运行时都不会出现。请看下面的输出副本：

我做了一些研究，根据我发现，去：
HKEY_LOCAL_MACHINE> SYSTEM>服务> Tcpip>参数

....并创建一个名称为MaxUserPort的REG_DWORD。然后将值设置为'65534'。我选择了这种方法，因为我的印象是问题是由于每次使用Internet Explorer驱动程序运行测试时都会打开一个新的端口。不幸的是，这样做还没有解决这个问题。我没有附加与上述错误相关的代码，因为我不认为它是相关的，因为错误将出现在我以前工作的某些地方的不同点。 >

如果有人可以帮忙，那将是很棒的。

解决方案

过去相同的问题，升级后Service Pack已经解决了。但也建议你看下面。

• 检查网络设置（防火墙，代理，防病毒软件）到
  找到权限被拒绝：连接的原因


• 找出它是Windows 7的问题，升级到SP1的问题
  已解决。


• 看起来当运行Web驱动程序时，它会打开许多TCP端口和
  耗尽可用端口，然后抛出此异常。检查
  Selenium版本如果较旧，然后2.44然后尝试升级到2.44和
  看看会发生什么。


• 运行以下命令，杀死所有运行的IEDriverServer.exe
  进程，taskkill / F / IM IEDriverServer.exe

I'm finding that, when running my selenium tests, I am getting errors in the console.....but these errors, confusingly don't appear on every run. See below for a copy of the output:

I did a bit of research and, based on what I found, went to: HKEY_LOCAL_MACHINE > SYSTEM > Services > Tcpip > Parameters

....and created a REG_DWORD with a name of 'MaxUserPort'. I then set the value to '65534'. I chose this method as I was under the impression the issue is due to a new port opening each time I run a test using Internet Explorer driver. Unfortunately, doing this has not resolved the issue. I've not attached the code relating to the above error as I don't think it's relevant, in that the error will appear at different points of my test.....in some places where it has worked previously.

If anyone can help, that would be great.

解决方案

I faced the same issue in past after upgrading Service pack it was resolved. But also suggest you to look at the below.

• Check your network settings (firewall, proxy, antivirus software) to find the cause of "Permission denied: connect"
• Find out it is windows 7's problem, upgrade to SP1 the problem solved.
• Seems when running web-driver, it will open many many TCP ports and exhaust the available ports, then throw this exception. Check Selenium Version if older then 2.44 then try upgrading to 2.44 and see what happens.
• Running the following command, killed all running IEDriverServer.exe processes, taskkill /F /IM IEDriverServer.exe
