What is LoadRunner?

Understand “JMeter vs LoadRunner” – LoadRunner is a proprietary tool developed by Micro Focus that is used for load testing, stress testing, and performance testing of web and mobile applications. It supports many technologies and protocols like HTTP, HTTPS, SOAP, and more. It can simulate thousands of users and measure the performance of the application under various load conditions.

It comprises several components, including the Virtual User Generator (VUGen), Controller, and Analysis. VUGen is used to create scripts that simulate user actions on the application. The Controller is used to manage and execute load tests, while Analysis is used to analyze the results of the load tests.

Action()
{
    lr_start_transaction(“Transaction Name”);

    web_url(“Web URL”,
        “URL=http://example.com/”,
        “Resource=0”,
        “RecContentType=text/html”,
        “Referer=”,
        “Snapshot=t1.inf”,
        “Mode=HTML”,
        LAST);

    lr_end_transaction(“Transaction Name”, LR_AUTO);

    return 0;
}
LoadRunner sends an HTTP GET request

In this example, LoadRunner sends an HTTP GET request to the URL “http://example.com/”. The “lr_start_transaction” and “lr_end_transaction” functions measure the time taken to complete the request and calculate the response time. The “web_url” function is used to simulate a user clicking a link in a web page, and the “LAST” parameter indicates that this is the last parameter for this function call.
