How to download and install Gatling tool | Gatling tool for Performance testing

Gatling is a highly capable load testing tool. It is designed for ease of use, maintainability and high performance.It is the best developer tool to load test your web applications.

Gatling comes with excellent support of the HTTP protocol that makes it a tool of choice for load testing any HTTP server. As the core engine is actually protocol agnostic, it is perfectly possible to implement support for other protocols.

Gatling’s architecture is asynchronous as long as the underlying protocol, such as HTTP, can be implemented in a non blocking way. This kind of architecture lets us implement virtual users as messages instead of dedicated threads, making them very resource cheap. Thus, running thousands of concurrent virtual users is not an issue.

How to capture all HTTP Responses in load runner

If you want to capture the http response of a page, but some times it may redirects as HTTP 301,HTTP 302 etc

By using the below code we can capture the status code and write itin to a variable.

HttpRetCode = web_get_int_property(HTTP_INFO_RETURN_CODE);

You need to place it after all the page request in the script. However, this will only capture the LAST status code received. If there is a redirection in between, it will not be captured. So to capture that we need to use web_reg_save_param function with the following arguments.

Use "ORD=ALL" argument to capture all occurrences and 

use "Search=Headers" argument to search the response header only

web_reg_save_param("HttpResponses","LB=HTTP/1.1 ", "RB= ", "Search=Headers" ,"ORD=ALL", LAST);

The HttpResponse variable contains all http requests and output log as a message.

Removing leading zero from the date in LoadRunner - 06/12/2020 to 6/12/2020

How to change 06/12/2020 to 6/12/2020? here is the code..

Action()
{
char month[10],day[10],year[10],startingDate[10]; //Declaration the variables here
int nonzeroday, nonzeromonth;

strcpy(startingDate,"");

lr_save_datetime("Today's Date is: %m/%d/%Y",DATE_NOW,"normal_date"); //Capturing Today's date and writing it to the Log

lr_output_message(lr_eval_string("{normal_date}"));

lr_save_datetime("%m",DATE_NOW,"month"); //Capturing month of date to a parameter
lr_save_datetime("%d",DATE_NOW,"day");  //Capturing day of date to a parameter
lr_save_datetime("%Y",DATE_NOW,"year");//Capturing year of date to a parameter

nonzeromonth=atoi(lr_eval_string("{month}")); // This it to remove zero from the month value
lr_save_int(nonzeromonth,"month");

nonzeroday=atoi(lr_eval_string("{day}"));  // This it to remove zero from the day value
lr_save_int(nonzeroday,"day");


strcat(startingDate,lr_eval_string("{month}")); //Concatenating  date with '/' to create a date
strcat(startingDate,"/");
strcat(startingDate,lr_eval_string("{day}"));
strcat(startingDate,"/");
strcat(startingDate,lr_eval_string("{year}"));


lr_save_string(startingDate,"p_startingDate");
lr_output_message("Corrected Date is: %s", lr_eval_string("{p_startingDate}"));

return 0;
}

Then your final output will be:

Action.c(34): Today's Date is: 06/12/2020
Action.c(65): Corrected Date is: 6/12/2020

function randomOrder(length, chars)
{
var string = '';
for (var i=length; i > 0; --i)
string += chars[Math.round(Math.random() * (chars.length - 1))];
return string;
} var orderNum = randomOrder(7, '0123456789'); 

document.getElementById("order_num").innerHTML = "ORDER #GMO" +orderNum;
</script>
