【问题描述】：
我已经使用 watir-webdriver / MiniTest 框架不到一个月了，它运行得非常好。但是，每次启动新版本时我都需要运行的包包含不到 100 个单独的测试，这需要一个多小时才能完成所有测试。
这就是我在 Centos-6-x86_64 上使用 Ruby、RVM、Watir、Rails 和 Firefox 设置 VPS 的原因。这样我就不必在笔记本电脑上运行脚本并等待它们完成，然后才能执行其他任何操作。
但是，当我尝试使用 irb 测试 watir 是否正常工作时，我收到以下错误：
Errno::EAFNOSUPPORT: Address family not supported by protocol - socket(2)
测试：
[root@V-9876 ~]# irb
1.9.3p448 :001 > require 'watir-webdriver'
=> true
1.9.3p448 :002 > b = Watir::Browser.start 'www.google.com'
Errno::EAFNOSUPPORT: Address family not supported by protocol - socket(2)

我一直在研究这个错误，我发现许多网站声称它是通过禁用 ipv6 来修复的，但我仍然收到这个错误。
不确定这是否会有所不同，但我还在此 VPS 上安装了 NGinX / PHP / MySQL
编辑 - ruby 文件发布在下面
require "watir-webdriver"
require 'watir-webdriver'
require 'headless'
headless = Headless.new
headless.start
browser = Watir::Browser.new :ff
browser.goto "http://remove-url-for-this-post.com"
puts ("Starting SearchValSelectFields")
browser.select_list(:id, "edit-select-sector").select("Finance and Accounting")
sleep (5)
browser.select_list(:id, "edit-select-subsector--3").select("All Sub-sector")
browser.select_list(:id, "edit-select-location").select("Singapore")
browser.button(:value,"Search").click
assert(browser.text.include?("Salary and employment forecast"))
browser.screenshots ('..\screenshots\SearchValSelectFields.png')
browser.select_list(:id, "edit-select-sector").select("Select Sector")
sleep(3)
browser.select_list(:id, "edit-select-subsector--2").select("Select Sub-sector")
sleep(3)
browser.select_list(:id, "edit-select-location").select("Select Location")
sleep(3)
browser.button(:value,"Search").click
assert(browser.text.include?("This field is required"))
browser.close
headless.destroy
有什么想法吗？
【问题讨论】：
-
所以你不想在你的 vps 上启动 firefox？那应该是无头运行吗？
-
我按照指南在 VPS 上安装了 firefox，这只是开始展示它的工作原理。我实际上希望运行 Chrome 和 IE。是的，这必须是无头的。
