Question

我试图开始实现watirgrid以便我可以并行运行测试..这是我开始测试的示例代码

require 'watirgrid'
require 'pp'
require 'pp'
# Start a Controller

controller = Controller.new
controller.start
# Start a Provider
provider = Provider.new(:browser_type => 'safari')
provider.start
grid = Watir::Grid.new
grid.start(:take_all => true)
pp grid.browsers.first
# Take the first browser on the grid and execute some Watir
browser = grid.browsers.first[:object].new_browser
browser.goto "http://google.com"
browser.close

但是当我执行此代码时，我得到以下错误

这是ruby 1.9.X用户的常见错误。在gem的github page中，创建者实际上已经展示了如何处理这个问题。引用：

在Ruby 1.9.2中不再可以枚举字符串，因此您可能会看到如下错误：

NoMethodError: undefined method each' for "192.168.0.134":String
from C:/RailsInstaller/Ruby1.9.2/lib/ruby/1.9.1/rinda/ring.rb:180:inlookup_ring

Rinda的Ruby核心库因为错误地在字符串上使用每个方法而被破坏。如果不使用猴子补丁，可以通过不使用查找中使用的DRb广播方法来避免watirgrid中的此错误。如果未指定控制器URI，则会发生这种情况。为了避免这种情况如果从命令行启动提供程序，请指定控制器URI

provider -c druby://203.51.48.187:11235 -d webdriver -b chrome
I, [2011-11-01 20:25:25 #49264]  INFO -- : Provider started on   : druby://203.51.48.187:54289
I, [2011-11-01 20:25:25 #49264]  INFO -- : Controller found on   : druby://203.51.48.187:11235
I, [2011-11-01 20:25:25 #49264]  INFO -- : Provider registered   : druby://203.51.48.187:11235

示例watirgrid脚本抛出错误
