检查点为参数的一个例子

检查点是LoadRunner的一个功能，用来验证业务功能的正确性。如果检查的内容是变化的，脚本该如何写呢？
     问题提出：LoadRunner订票网站例子中，创建一个虚拟用户脚本，在登陆完成之后，设立一个检查点，来检查“welcome， xxx”。其中xxx为登陆的用户名称。
      解决方法：
     1）使用web_find() 做检查点
     Action()
{
//连接字符串，把welcome和用户名组合成一个字符串
 char teststring[1024]="Welcome, ";
 strcat( teststring,lr_eval_string("{username}") );
 lr_output_message("%s", teststring);
 lr_save_string( teststring,"findtext" );
 // [WCSPARAM WCSParam_Diff1 43 97279.0909680032fAADHQDpctVzzzzHDAAccpHfQtf]
//Parameter {WCSParam_Diff1} created by Correlation Studio
//关联操作
 web_reg_save_param("WCSParam_Diff1",
  "LB=userSession value=",
  "RB=>",
  "Ord=1",
  "RelFrameId=1.2.1",
  "Search=Body",
  "IgnoreRedirections=Yes",
  LAST);
 web_url("WebTours",
  "URL=http://127.0.0.1:1080/WebTours/",
  "TargetFrame=",
  "Resource=0",
  "RecContentType=text/html",
  "Referer=",
  "Snapshot=t1.inf",
  "Mode=HTML",
  LAST);
 lr_think_time(11);
    lr_start_transaction("test\");
 web_submit_data("login.pl",
  "Action=http://127.0.0.1:1080/WebTours/login.pl",
  "Method=POST",
  "TargetFrame=body",
  "RecContentType=text/html",
  "Referer=http://127.0.0.1:1080/WebTours/nav.pl?in=home",
  "Snapshot=t2.inf",
  "Mode=HTML",
  ITEMDATA,
  "Name=userSession", "Value={WCSParam_Diff1}", ENDITEM,
  "Name=username", "Value={username}", ENDITEM,     //参数化用户名
  "Name=password", "Value=bean", ENDITEM,
  "Name=JSFormSubmit", "Value=off", ENDITEM,
  "Name=login.x", "Value=42", ENDITEM,
  "Name=login.y", "Value=13", ENDITEM,
  LAST);
//检查点
 web_find("web_find",
  "What={findtext}",
  LAST);
   lr_end_transaction("test", LR_AUTO);
 return 0;
}
     2）使用web_reg_find()做检查点
Action()
{
//字符串操作，生成要检查的字符串变量
char teststring[1024]="Welcome, <b>";
 strcat( teststring,
  lr_eval_string("{username}") );
 lr_output_message("%s", teststring);
 lr_save_string( teststring,"findtext" );
 //关联
// [WCSPARAM WCSParam_Diff1 43 97279.0909680032fAADHQDpctVzzzzHDAAccpHfQtf]   Parameter {WCSParam_Diff1} created by Correlation Studio
 web_reg_save_param("WCSParam_Diff1",
  "LB=userSession value=",
  "RB=>",
  "Ord=1",
  "RelFrameId=1.2.1",
  "Search=Body",
  "IgnoreRedirections=Yes",
  LAST);
 web_url("WebTours",
  "URL=http://127.0.0.1:1080/WebTours/",
  "TargetFrame=",
  "Resource=0",
  "RecContentType=text/html",
  "Referer=",
  "Snapshot=t1.inf",
  "Mode=HTML",
  LAST);
 lr_think_time(11);  
 lr_start_transaction("test");
 //检查点
 web_reg_find("Text={findtext}",
  "Search=Body",
  LAST);
 web_submit_data("login.pl",
  "Action=http://127.0.0.1:1080/WebTours/login.pl",
  "Method=POST",
  "TargetFrame=body",
  "RecContentType=text/html",
  "Referer=http://127.0.0.1:1080/WebTours/nav.pl?in=home",
  "Snapshot=t2.inf",
  "Mode=HTML",
  ITEMDATA,
  "Name=userSession", "Value={WCSParam_Diff1}", ENDITEM,
  "Name=username", "Value={username}", ENDITEM,  //参数化登陆名称
  "Name=password", "Value=bean", ENDITEM,
  "Name=JSFormSubmit", "Value=off", ENDITEM,
  "Name=login.x", "Value=42", ENDITEM,
  "Name=login.y", "Value=13", ENDITEM,
  LAST);  
 lr_end_transaction("test", LR_AUTO);
 return 0;
