Question

Watir webdriver有一个非常讨厌的问题..

我调试了一下，发现我总是在一个简单的@ browser.goto行上得到TimeOut :: Error，即使我可以直观地看到页面已经完全加载了......

场景如下：打开浏览器，转到网址，点击几个链接，然后突然在某一点上，脚本停止继续浏览，等待大约30秒以上并抛出错误。试过Chrome和FF：Chrome更糟糕，通常第二或第三个链接点击会触发;对于FF，有时需要10多页浏览...

投注存在一些环境或可比性问题：

jd@deskbox:~$ uname -am
Linux deskbox 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
jd@deskbox:~$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]

jd@deskbox:~$ gem -v

jd@deskbox:~$ gem list|grep webdriver
selenium-webdriver (2.12.0)
watir-webdriver (0.5.3)

有人可以为此提供帮助吗？源代码在这里：

#!/usr/bin/env ruby
require 'watir-webdriver'
require 'pry'

class Search
    attr_accessor :browser, :company_url, :company_name

    def initialize()
        @browser = Watir::Browser.start 'http://www.google.com', :chrome
    end

    def visit_company_home_via_google(company)
        @company_name = company
        @browser.goto "http://www.google.com/search?q=#{company}"
        link = @browser.div(:id=>'ires').link
        return nil unless link.exists?
        @browser.goto link.href
        @company_url ||= @browser.url
        @company_url
    end


    def logoff()
        @browser.close if @browser
    end

end
s = Search.new
puts s.visit_company_home_via_google("github")
puts s.visit_company_home_via_google("Mashable")
puts s.visit_company_home_via_google("Barracuda Networks")
s.logoff

我的结果如下：

我认为Chromedriver中存在一个错误，它没有正确返回URL。我让你的例子使用：

require 'watir-webdriver'

class Search
  attr_accessor :browser, :company_name

  def initialize
    @browser = Watir::Browser.start 'http://www.google.com', :chrome
  end

  def get_company_url(company, url=nil)
    @company_name = company
    @company_url = url
    @browser.goto "http://www.google.com/search?q=#{company}"
    link = @browser.div(:id=>'ires').link
    return nil unless link.exists?
    @company_url ||= @browser.driver.current_url
  end

  def logoff()
    @browser.close if @browser
  end

end

s = Search.new
puts s.get_company_url 'Barracuda Networks'

Watir / Selenium - browser.goto在Chrome和Firefox上不断出现TimeOut错误
