Question

我们有一个虚拟的Windows 7映像，我们的CI在IE10上运行我们的功能测试。功能测试使用Cucumber + Watir-Webdriver在Ruby中编写。

大多数情况下它工作正常，但每次测试都会因以下异常而失败：

EXCEPTION: SocketError:  getaddrinfo: No such host is known. 
       C:/Ruby193/lib/ruby/gems/1.9.1/gems/selenium-webdriver-2.34.0/lib/selenium/webdriver/common/platform.rb:169:in `getaddrinfo'

在重新启动虚拟机之前，通常没有进一步的测试运行，然后它会再运行几天。

我检查了selenium-webdriver的代码，失败的行是：

info = Socket.getaddrinfo "localhost", 80, Socket::AF_INET, Socket::SOCK_STREAM

我们没有正在使用的代理，并且只能在内部网内进行通信。但是可以上网。 hosts文件不包含localhost的任何条目。我们正在使用selenium-webdriver 2.34.0。我们的Win7 / IE9虚拟机具有相同的配置没有这样的问题。

Answer 1

hosts文件不包含localhost的任何条目。

嗯，那可能是你的问题。如果您未在本地解析localhost，则将使用默认域发送DNS查询，例如localhost.example.com。您的DNS服务器可能会也可能无法正确回答该查询。

Webdriver在IE10 / Win7上导致“SocketError：getaddrinfo：没有这样的主机已知”
