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Winxp系统的防火墙关闭）。

如下图所示：
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：
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：
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=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“Welcome”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 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/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}", ENDITEM,
"Name=login.x", "Value=58", ENDITEM,
"Name=login.y", "Value=13", ENDITEM,
LAST);
web_find("web_find",
"LeftOf=,",
"What={username}",
LAST);
web_image("SignOff Button",
"Alt=SignOff Button",
"Snapshot=t3.inf",
LAST);
return 0;
}
