在linux Jenkins CI服务器上使用Xvfb实现Firefox的无头测试自动化

Question

我正在尝试使用Xvfb和firefox来运行无头测试自动化。但是，我在启动xvfb时收到以下消息。

​

XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
_XSERVTransOpen: transport open failed for inet6/cvms1247:99
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6

​

然后我尝试了以下命令：

  Xvfb :001 -nolisten inet6
  export http_proxy=http-proxy.nwie.net:8080

以下消息消失。

  XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
 _XSERVTransOpen: transport open failed for inet6/cvms1247:99
 _XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6

headless的用法：

  if OS::windows? || ENV['PhantomJS'] == 'true'
    browser = Selenium::WebDriver.for :remote, url: 'http://localhost:8001'
  elsif OS::linux?
    require 'headless'
    headless = Headless.new
    headless.start
    browser = Selenium::WebDriver.for :firefox
    at_exit do
      browser.close
      headless.destroy
    end
  else
    raise 'Unknown OS'
  end

环境：

 Ruby: 1.9.3
 Jenkins: 1.58
 Selenium webdriver: 2.53
 headless: 2.3.1
 Xvfb: yum install xorg-x11-server-Xvfb
 firefox: 33.0
 Linux: 2.6.32-573.12.1.el6.x86_64

我遗漏了什么？

没有错误，或者您忘记将其包括在内。

您发布的示例输出不包含"error“一词。

您可能会被"Unable to open socket for inet6“消息误导。对我来说，这看起来像是信息性消息，告诉我这个x服务器将不会使用ipv6。之后的初始化成功了，所以最有可能的是ipv4工作正常。
