主要学习Web(HTTP/HTML)协议的两种录制方式,重点包括以下内容:

--脚本录制的基本原则

--HTML和URL based script介绍

--选择录制方式的原则

--HTML based script设置介绍

 1、脚本录制的基本原则

(1)充分考虑脚本的执行效率。

性能测试脚本关注的是如何模拟用户的真实行为。因此,用于测试的脚本应该接近用户的真实操作。这就要求录制后的脚本在修改的过程中不要增加过多内容,尤其是不能降低其运行效率。例如尽量不要增加循环、检查等操作,除非这些操作是必须的。

"基于此:检查点的设置一定要合理"

(2)录制重要的用户业务

要录制常用的、使用频率较高的业务来进行测试,不要什么内容都录制。

(3)选择需要的进行录制

在Web性能测试中,如果有些操作对于用户所关注的事物没有什么影响,那么可以不进行录制。例如,一些查询事物中,选择查询条件页面的请求过程可以不予录制,但对于一些要传递查询参数的过程则必须录制。(即凡是与Server服务器端进行交互的必须录制

(4)录制前对参数要进行正确的配置

2、HTML和URL based script介绍

(1)基本概要

HTML based script:可以为每个用户请求生成单独的函数。

URL based script:可以捕获所有作为用户操作的结果发送到服务器的HTTP请求,然后一条条记录下来。它甚至可以捕获非HTML的程序,比如小程序和非浏览器应用程序。

HTML这种录制方式录制出来的脚本直观,易于理解和维护。而URL生成的脚本看起来比较长比较多。

(2)选择配置路径

技术分享

当然还可以在:Tools-->>Recording Options处进行选择设置。

(3)两种录制方式录制出的脚本比较。

录制场景:Web Tours网站的登陆和退出

使用HTML based script录制的脚本如下显示:

 3、通过两种录制方式的比较,我们得出脚本录制的原则,如下:

[1]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。

[2]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,也要使用URL方式录制。

[3]基于浏览器的应用程序中使用了HTTPS安全协议,使用URL方式进行录制。

[4]对于初学者来说,如果HTML录制方式不成功,可以换成URL方式录制。

4、HTML based script设置介绍

(1)用来描述用户行为的脚本。直接创建的URL(web-url)、表单提交(Web_submit_form)、链接(Web_link)、和图像(Web_image)等函数。

(2)仅包含明确的URL脚本。这些脚本中所有的链接、图像请求和URL操作都被录制为Web_url函数,而表单提交则被录制为Web_submit_data函数。
