Watir / Selenium – browser.goto在Chrome和Firefox上不断出现TimeOut错误
Watir webdriver遇到了一个非常烦人的问题..
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…
场景是这样的：打开浏览器，转到url，点击几个链接，然后突然一点，脚本停止继续浏览，等待大约30秒以上并抛出错误。 尝试了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…
打赌存在一些环境或可比性问题：

我的结果是：

我认为Chromedriver中有一个错误，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'
