文本检查点的疑问

higkoo · 发表于 2007-12-14 11:09:06

在脚本视图，给页面添加“文本检查点”时有两种方法，如图示（A）、（B）。

今天用WebTours尝试如下操作：
1、创建了100个用户，用户名为test001、test002……test100，密码同用户名一样；
2、录制一个登录、退出的脚本；
3、参数化用户名和密码；
4、设计登录退出100个循环，用户随机选择；
5、添加图像检查点和文本检查点。

图像检查点用SRC，Check很容易通过。文本检查点有两种方式，容易报错，贴出来请高手指点千秋。此页面的HTML代码如下：
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-US">
<head><title>Welcome to Mercury Tours</title></head>
<body bgcolor="#E0E7F1">
<img src=/MercuryWebTours/images/fma-performance-center.jpg><p />
<style>blockquote {font-family: tahoma; font-size : 10pt}H1 {font-family: tahoma; font-size : 22pt; color: #993333}small {font-family: tahoma; font-size : 8pt}H3 {font-family: tahoma; font-size : 10pt; color: black}TD {font-family: tahoma; font-size : 10pt; color: black}</style>
<blockquote>Welcome, <b>jojo</b>, to the Mercury Tours reservation pages.<BR>Using the menu to the left, you can search for new flights to book, or review/edit the flights already booked. Don't forget to sign off whenyou're done!</blockquote>
</body></html>

登录后，文本检查：显示登录的用户名（test001、test002....test100），老是出错（找不到指定数据）。

如果设置为查找test，就都可以成功，不知哪个环节出错了？

登录的用户名是"test{Num}"参数化的常量＋参数，｛Num｝是随机从001～100的抽取的。

使用B操作
web_reg_find("Search=Body",
      "Text={Num}",
      LAST);
即查找登录用户的test的后缀，验证失败，附图：

使用操作（A）也失败，附图：

另外，图上的左边界和右边界，是指界面上的体现还是HTML源码的左右边界？

1.在login.c中增加检查代码测试一下
2.更换检查点进行测试
Login()
{

lr_save_string( lr_eval_string("test{Num}"),
"Words" );

lr_start_transaction("登录系统");

web_reg_find("Text=test",
"SaveCount=count",
LAST);
web_submit_data("login.pl",
"Action=http://test3:2000/mercurywebtours/login.pl",
"Method=POST",
"RecContentType=text/html",
"Referer=http://test3:2000/mercurywebtours/nav.pl?in=home",
"Snapshot=t2.inf",
"Mode=HTML",
ITEMDATA,
"Name=userSession", "Value={WCSParam_Diff1}", ENDITEM,
"Name=username", "Value={Words}", ENDITEM,
"Name=password", "Value={Words}", ENDITEM,
"Name=JSFormSubmit", "Value=off", ENDITEM,
"Name=login.x", "Value=0", ENDITEM,
"Name=login.y", "Value=0", ENDITEM,
LAST);
if (atoi(lr_eval_string("{count}")) > 0){
         lr_output_message("----%被成功检查！",lr_eval_string("{Num}"));
   }

else{
         lr_error_message("----%s不能被检查到",lr_eval_string("{Num}"));
         return(0);
   }
web_find("web_find",
"What=test",
LAST);

lr_end_transaction("登录系统", LR_AUTO);

return 0;
}

楼上 swordtong 的脚本是可以正常运行的，
你的脚本是查找的test，然后输出{Num}。

能否这样？：
假设登录用户为test088，查找的就是test088而不是只查找test。

Zee · 发表于 2007-12-14 12:20:15

我想楼主对这个检查点的理解不大对。

你搜索的是{Num}，而在运行中已经被参数替换了。所以应该是搜索不成功的。

我觉得你在楼上说的方式可行。

higkoo · 发表于 2007-12-14 12:53:01

登录用户为test088，查找的就是test088

登录用户是动态（参数化）的。检查点要与之对应才行，如何实现？

同问!

这个检查点可以这么设置：
脚本如下：

Action()
{

web_url("WebTours",
"URL=http://127.0.0.1:1080/WebTours/",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t1.inf",
"Mode=HTML",
LAST);
lr_think_time(6);

web_reg_find("Text={name}",
"Search=Body",
LAST);
web_submit_form("login.pl",
"Snapshot=t2.inf",
ITEMDATA,
"Name=username", "Value={name}", ENDITEM,
"Name=password", "Value={password}", ENDITEM,
"Name=login.x", "Value=27", ENDITEM,
"Name=login.y", "Value=3", ENDITEM,
LAST);

web_image("SignOff Button",
"Alt=SignOff Button",
"Snapshot=t3.inf",
LAST);

return 0;
}

结果如下：

呵呵，你把一个参数，保存到另一个参数里，然后再检查，和你直接用那个参数检查有什么区别？

你这样不是多了一道手续吗？

是多余了

相当手动实现了将{Num} Each occurrence 变为了Each iteration。

终于忙完了来看看，lz的方法明显的绕弯了:p
zee在9楼的代码很清晰，这个方法已经很优化了。
还有顺便说一句现在一般很少用web_find这个方法了。当时有一篇帖子说过2种方法的优劣之处，具体记得不是很清楚了，最后还是推荐使用web_reg_find，有时间的话可以找找看看具体原因。

把lr_save_string转换的那句给删掉之后，再用以前的脚本，全部都是正常的了：

   web_reg_find("Text=test{Num}",
            "Search=Body",
            LAST);

      web_submit_data("login.pl",
            "Action=http://test3:2000/mercurywebtours/login.pl",
            "Method=POST",
            "RecContentType=text/html",
            "Referer=http://test3:2000/mercurywebtours/nav.pl?in=home",
            "Snapshot=t2.inf",
            "Mode=HTML",
            ITEMDATA,
            "Name=userSession", "Value={WCSParam_Diff1}", ENDITEM,
            "Name=username", "Value=test{Num}", ENDITEM,
            "Name=password", "Value=test{Num}", ENDITEM,
            "Name=JSFormSubmit", "Value=off", ENDITEM,
            "Name=login.x", "Value=0", ENDITEM,
            "Name=login.y", "Value=0", ENDITEM,
            LAST);
直接这样运行也是成功的。

  可能是用lr_save_string后前后两者有什么差异或其它未知内部原因导致的错误吧。

从用户脚本来看就不用管这个问题了，不过理论上来说应该是某个地方还存在有问题。
