LoadRunner检查点使用小结

1、LoadRunner检查点使用小结LR中检查点有两种：图片和文字。这两种检查点可用以下三个函数实现：web_find()、web_reg_find()和web_image_check()下面分别介绍三种函数的用法1、web_find()函数函数作用：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

2、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。2、web_reg_find()函数函数作用：在缓存中查找相应的内容参数举例：web_reg_find("Search=Body","SaveCount=ddd","Test=

3、aaa",LAST);参数解释： Search用来定义查找范围，SaveCount定义查找计数变量名称，该参数可以记录在缓存中查找内容出现的次数，可以使用该值，来判断要查找的内容是否被找到例如上述参数举例中的意思就是Body中查找内容为aaa的信息，并将出现次数记录在变量ddd中。函数用法：该函数是在缓存中查找相应的内容，所以要放在查找内容之前。注：在录制过程中添加的检查点，用到的函数是web_reg_find()，且参数只有“Text=”3、web_image_check()函数函数作用：在页面中查找一个具体的图片。参数说明：web_image_check("web_im

4、age_check","Alt=","Src=",LAST);参数解释：“Alt”和“Src”的值直接取该图片在网页源代码中相应参数的值。函数用法：该函数是在缓存中查找相应的内容，所以要放在查找内容之前。注意事项：使用该函数时，要在Vuser->Run-Tme Settings中勾选Enable Image and text check，具体操作请看web_find()中的注意事项。经过测试，该函数用到查找内容前面或后面，都不影响查找结果。举例说明（脚本）该脚本记录的是登陆系统后退出的操作，在脚本中用到atoi()函数和lr_eval_s

5、tring(”SaveCount定义的变量”)两个函数结合使用，判断查找内容出现的次数是否大于0，若大于0，则输入登录成功的信息。vuser_init()web_url("xjcost","URL=http:/gczj-server8:9205/xjcost/","Resource=0","RecContentType=text/html","Referer=","Snapshot=t1.inf","Mode=HTML",EXTRARES,"Ur

11、输出“Log on successfully!”if(atoi(lr_eval_string("欢迎您_Count")>0)lr_output_message("Log on successfully!");elselr_error_message("Log on failed!");return 0;return 0;/atoi()函数的作用是将一个ASCII字符串转换为整型/lr_eval_string()函数作用是取得参数值，将字符串变量中的参数值替换为当前的参数值并将这个字符串返回vuser_end()lr_think_
