1、软件测试案例分析 实验三LoadRunner检查点DOC南昌航空大学实验报告 2013/06/06 课程名称： 软件测试案例分析 实验名称： LoadRunner检查点 班级： 姓名： 同组人： 指导教师评定： 签名： 一、 实验目的（1）理解和掌握性能测试的基本原理和方法。（2）掌握LR检查点的使用与脚本设计。二、实验要求（1）运用LR录制订票操作的脚本。（2）回放脚本，观察结果。（3）对订票的金额设置检查点。三、实验内容（一）、使用LR录制mercury tours订票系统订票操作的脚本。具体步骤如下：（1）打开LR的录制配置窗口，将登陆页面的脚本录制到vuser_init动作中（确认将W
2、inxp系统的防火墙关闭）。如下图所示：（2）开始录制，打开http:/localhost/MercuryWebTours/订票页面，选择用户jojo/bean，或者joe/young登陆订票系统，如下图所示；（3）重新选择recording窗口的动作下拉列表，将以下的操作录制到action动作中；（4）继续录制操作，点击flights按钮，进入订票窗口，选择Departure City为Frankfurt，Arrival City为London， No of Passengers为1，其他为默认设置，如下图所示：（5）点击continue按钮，继续录制，进入航班选择页面，选择起飞时间为8am
3、的航班，如下图所示：（6）点击continue按钮，继续录制，进入信用卡支付页面，如下图所示：（7）在credit card中输入 5602 4506 2220，Exp Date输入08/16，点击purchase flight按钮。进入机票确认窗口。如下图所示：（8）订票结束，点击sign off按钮返回登录页面。（二）、下面通过设置检查点函数来检查页面中的相关信息，步骤如下：（1）使用web_find()函数，来检查登录成功以后的欢迎页面是否是以“Welcome”开始的。如下图所示：函数作用：在页面中查找相应的内容参数举例：web_find(web_find,RighOf=a,LeftOf
4、=b,What=name,LAST);参数解释：web_find定义该查找函数的名称；“LeftOf”和“RighOf=”用来定义查找字符的左右边界；“What=”定义查找内容。例如上述参数举例中的意思就是在页面中查找左边界为b，右边界为a，内容为name的信息函数用法：该函数是在查找页面中的内容，所以要放在要查找的内容的后面。注意事项：使用该函数时，要在Vuser-Run-Tme Settings中更改下设置勾选Enable Image and text check系统默认是不勾选该选项的。关于该函数的其他说明：该函数只能在基于HTML模式录制的脚本中进行查找。（2）由于欢迎页面“Welco
5、me”的右侧是逗号“,”，所以在VUGen中，将script view切换为Tree view，在vuser_init动作中，选择submit form:login.pl，鼠标右键单击选择insert after，如下图所示：（3）在插入窗口中展开web checks，选择Text Check，选择ok，如下图所示：（4）选择OK以后，在Text Check Properties的设置窗口中，输入Search for为Welcome，选中Left of，表示应在某文本的左边出现，输入逗号”,”，点击确定。（5）将VUGen返回script view视图，此时在Vuser_init中可以查看到插
6、入的文本检查点脚本。如下图所示：（6）由于web_find是在页面中查找文本是否出现，最好在web_submit_form的脚本后插入thinktime，保证等待页面打开后再来查找检查点的文本，因此修改脚本如下所示：（7）脚本确认以后，回放脚本，查看execution Log，能发现如下的日志“web_find successful. 1 occurrence(s) of “Welcome” found”，表示检查点执行正确： （三）若检查订单确认页面的“Total cost”是否为266，请录制脚本设置检查点。（四）在订票系统登录后，将显示欢迎的页面，具体页面如下：在该页面中，如果以joe登
7、陆，则在页面中将显示welcome，joe，.，如何检查系统是否显示了当前登陆的用户？此时，可以通过带参数的web_find函数来检查。（1） 新建一个新的LR脚本文件，重新录制订票系统的登陆脚本（由于该脚本将循环执行，所以应录制到action动作中），并将用户名和密码参数化，其中用户名和密码如下所示（注意存储数据的文件名为username.dat）： Username Password joe young jojo bean（2） 在tree view视图下，选择submit form，在右键菜单中选择”Insert After”，插入检查函数web_find；（3）在插入窗口中展开web
8、checks，选择Text Check，选择ok，如下图所示：（4）选择OK按钮后，在Text Check Properties窗口的search for文本框中选择，按钮abc，表示将要搜索的文本参数化， （5）在弹出的select or create parameter的窗口中，输入parameter name 为username，点击proerties按钮，在弹出的参数属性窗口中，选择file path 为之前参数的数据文件username.dat. 在select column中选择1，表示从数据文件的第一列取数据。（6）设置完成后，点击close，点击确定，返回web_found的设
9、置窗口，如下图所示：（7）在left of 文本框中输入逗号”,”，点击确定。（8）点击确定后，返回到script view，能查看到插入的web_find函数。（9）在script view视图中，选择action，右键点击选择runtime settings，如下图所示：（10）在run logic中设置循环次数为2，点击确定。（11）在preferences中，勾选Enable Image and text check系统默认是不勾选该选项的。（12）回放脚本，在excution log中，能发现两个用户名都带入并且在页面中存在。（13）将参数的数据文件加入一组新的用户名和密码：tom/
10、mountain，将循环次数设置为3，重新运行脚本，观察结果。将脚本和报告以及执行日志保存到实验报告。脚本： URL=http:/localhost/MercuryWebTours/, Resource=0, RecContentType=text/html, Referer=, Snapshot=t1.inf, Mode=HTML, LAST); web_submit_form(login.pl, Snapshot=t2.inf, ITEMDATA, Name=username, Value=username, ENDITEM, Name=password, Value=password,
