LoadRunner基于HTML-based script和URL-based script方式录制的区别和各自的使用场景

时间:2021-09-22 04:46:32

一、区别:

  为了更加直观的区别这两种录制方式,我们可以分别使用这两种方式录制同一场景(打开百度首页)然后进行对比,录制的代码如下:

  • HTML-based script方式打开百度首页:
Action()
{
web_url("www.baidu.com",
"URL=http://www.baidu.com/",

}

 从上面可以看出:

  • HTML-based script:这种方式录制的代码只生成了一个函数,所有请求全放在这个函数里面,即:一个操作(可能包含多个请求)会生成一个函数,这种方式看起来比较简洁
  • URL-based script:这种方式会生成很多函数,它将每个请求都单独成一个函数,这种方式更接近请求-响应的本质

二、HTML-based script模式下-->高级选项Sctipt type两种方式的区别:

  •   A script describing user actions(e.g. web_link,web_submit_form)
  •   A script containing explicit URLs only(e.g. web_url, web_submit_data)

同上面一样,我们还是通过录制同一场景的方法直接来对比这两种方式的区别(录制loadrunner自代的示例程序)

  • A script describing user actions(e.g. web_link,web_submit_form)
Action()
{
  //如果注释掉这个函数,执行时会失败
web_url("WebTours",
"URL=http://127.0.0.1:1080/WebTours/",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t9.inf",
"Mode=HTML",
EXTRARES,
"Url=../favicon.ico", "Referer=", ENDITEM,
LAST);

  //提交表单,依赖上下文,如果没有上面的函数,会执行失败
web_submit_form("login.pl",
"Snapshot=t10.inf",
ITEMDATA,
"Name=username", "Value=jojo", ENDITEM,
"Name=password", "Value=bean", ENDITEM,
"Name=login.x", "Value=59", ENDITEM,
"Name=login.y", "Value=9", ENDITEM,
LAST);
return ;
}
  • A script containing explicit URLs only(e.g. web_url, web_submit_data)
Action()
{
  //注释掉这个函数,这个场景执行不会失败,因为web_submit_data的函数中包含了具体的URL(如下标红的action)
web_url("WebTours",
"URL=http://127.0.0.1:1080/WebTours/",
"TargetFrame=",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t1.inf",
"Mode=HTML",
EXTRARES,
"Url=http://conf.xmp.kankan.com/vus/vipjs/vus_main.js", "Referer=", ENDITEM,
LAST);   //提交数据到具体的URL,不依赖上下文
web_submit_data("login.pl",
"Action=http://127.0.0.1:1080/WebTours/login.pl",
"Method=POST",
"TargetFrame=",
"RecContentType=text/html",
"Referer=http://127.0.0.1:1080/WebTours/nav.pl?in=home",
"Snapshot=t3.inf",
"Mode=HTML",
ITEMDATA,
"Name=userSession", "Value=115841.053786958fQfifHtpcAtVzzzHDfHfVpttfccf", ENDITEM,
"Name=username", "Value=jojo", ENDITEM,
"Name=password", "Value=bean", ENDITEM,
"Name=JSFormSubmit", "Value=off", ENDITEM,
"Name=login.x", "Value=47", ENDITEM,
"Name=login.y", "Value=9", ENDITEM,
LAST);return ;
}

总结:

  • web_submit_form: 上下文相关的,依赖上下文才能提交,比较符合人们的操作习惯。
  • web_submit_data:  上下文不相关,每个函数都指定了具体的url地址,可以直接提交成功,如果只关注协议,不需要关注页面,可使用这种方式录制。

三、使用场景:

  • 基于浏览器的应用程序推荐使用HTML-based Script
  • 不是基于浏览器的应用程序推荐使用URL-based Script。
  • 如果基于浏览器的应用程序中包含了JavaScript 并且该脚本向服务器产生了请求,比如DataGrid 的分页按钮等,flash等,也要使用URL-based 方式录制
  • 基于浏览器的应用程序中使用了HTTPS 安全协议,使用URL-based 方式录制
