ruby on Httpwatch 脚本

HTTPwatch官方：http://www.httpwatch.com/rubywatir/

ruby on httpwatch例子：http://www.httpwatch.com/rubywatir/site_spider.zip （这个例子官网可能更新）

得到这个例子后做了一些中文注释，对一些代码进行了删减，主要修改内容如下：

1、在url = gets.chomp!上面添加($*[0].nil?)?(url = url):(url = $*[0])，目前URL可以在命令行加载，也可以在脚本中固定；命令行方式用法：ruby 脚本名 网站名，具体的用法请参看脚本中的注释，说明一下 在URL前面不要添加http://

2、注视掉了两个break，在ruby186版本没有问题，在ruby192这样的高版本上会有错，需要注视掉

3、注视掉 plugin.Container.Quit(); 即不退出IE，运行完毕后，测试人员需要去查看结果

运行时问题：如果测试机网速较低可能出现超时而退出

两个脚本放在同一目录下，url_ops.rb未作变动，在cmd中执行即可。
