How to get page size data in LR scripts part2--extract common code into header file

Step1:
Create your common method in Loadrunner installation folder， which is usually in ..\Program Files\HP\LoadRunner\include

In calpagesize.h file, here is the source code which simply return the “current page size” you want to measure:

int calpagesize(int Pre_size){

int Temptotalsize=0;
int currentResponseSize = 0;

Temptotalsize = web_get_int_property(HTTP_INFO_TOTAL_RESPONSE_STAT);

return currentResponseSize = Temptotalsize - Pre_size;

}

Step2:apply the calpagesize() method:

Adding #include “calpagesize.h” in your globals.h file

Step3: Adding calculate page size code(in red line) into action:

Take Yahoo home page for example:
Action()
{
int Pre_page_size=0;
int cur_page_size=0;


Pre_page_size=web_get_int_property(HTTP_INFO_TOTAL_RESPONSE_STAT); //get accumulate page size data before sending next request

web_url("www.yahoo.com",
"URL=http://www.yahoo.com/",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t1.inf",
"Mode=HTML",
LAST);

if (flag==1){ //flag==1 means trigger the page size func code

cur_page_size = calpagesize(Pre_page_size); //return yahoo home page page size

lr_save_int(atoi(lr_eval_string("{Avg_01_PageSize}"))+cur_page_size, "Avg_01_PageSize"); //save into parameter ” Avg_01_PageSize”

}

}
So normally, we may need to add 4 lines before and after the page you want to calculate the size.

finally, you can calculate the page size in Vuser_end():

lr_message("Avg_01_PageSize = %d", atoi(lr_eval_string("{Avg_01_PageSize}"))/atoi(lr_eval_string("{Iterations}")));

enjoy!
