Scripting

一、In drivers which support it, you can easily execute JavaScript:

page.execute_script("$('body').empty()")
For simple expressions, you can return the result of the script. Note that this may break with more complicated expressions:

result = page.evaluate_script('4 + 4');
二、  page.execute_script("$('div:eq(0)').length")
     page.execute_script("document.getElementById('wrapper')")

模拟浏览器，人工测试

1. 文本框：

   直接填充   :      fill_in("#{@user.id}_name",:with=>"jdo")  

   通过节点赋值 :  find(:xpath,"//html/body/div[2]/div[2]/div/div/div[3]").set("123456")

   获取文本框值： find(:xpath,"//html/body/div[2]/div[2]/div/div/div[3]").value.should=="expect value"

 3.安装 passenger
  sudo gem install passenger
  sudo passenger-install-apache2-module
 4. 按照提示 编辑 httpd.conf ,并添加如下配置

# 在本地服务器建立 rubygems.org 的镜像缓存，以提高 gem 的安装速度
# 此配置设置缓存过期为1天，也就是说，新上的 gem 无法马上安装
# 做这个起什么作用？
# rubygems 的很多资源文件是存放到 Amazon S3 上面的，由于 GFW 对某些 S3 服务器又连接重置或丢包，导致 gem 安装异常缓慢或有时候根本无法连接安装。
# 而通过这种跳板的方式可以很好的解决这个问题，当然前提是 Nginx反向代理 服务器需要在国外
