Using RegEx (Regular Expressions) in Jmeter – CoRelation in Jmeter


In this article I will describe how to use the Regular expression extractor in Jmeter for the dynamic data corelation needs of web requests. I will first discuss how to add a RegEx to a webrequest, the basics terminologies associated with RegEx and then describe how different types of regular expression requirements can be met.

Revisiting Performance Testing Basics


In this article, I have attempted to clarify some basic and most important terminologies and concepts pertaining to performance and the load testing arena. The Performance of web sites is increasingly becoming important. Companies are realising the importance of snappy performance. Losses caused to businesses due to poor performance issues can be huge (including the company’s image). […]

AJAX TruClient – Parameterization, Text Verification and Object Identification


Everyday I see at least one discussion or thread related to Ajax TruClient protocol. Many performance engineers across the world are starting to use this protocol to test their web apps. Most of the questions on TruClient technology are based on three primary steps of scripting – Parameterization, Text Verification and Corelation. In this article, I will walk […]

AJAX TruClient – The next Revolution in Performance Testing domain

Last week, I had a chance to work on the AJAX TruClient protocol launched in the latest version of LR (LR 11). I was amazed to see a totally different manner of scripting followed with this protocol. The object identification technology made my scripting and debugging task a piece of cake. The non-requirement of dynamic correlation reduced the scripting complications and […]

LoadRunner to JMeter – A successful transition


 It all began on the day when a bunch of three performance testers were given a task of migrating the performance testing activities of multiple applications of a client to an open source tool. This included architectural level migration, resource knowledge transition and testing-operation transition from a licensed tool (LoadRunner) to an open source tool. […]

Citrix Protocol on LoadRunner – Tips and Tricks Part 3

I’ve previously published two articles on Tips and tricks helpful to performance test Citrix applications with Loadrunner. The articles can be found here -> Citrix Protocol on LR – Tips & Tricks (Part 1) Citrix Protocol on LR – Tips & Tricks (Part 2) In this article, I will cover the following: Remotely managing hung […]

Loadrunner Parameter Types – An Overview

Parameterization provides the ability to use different values in scripts and thus helps create data driven test scenarios. Parameterization also reduces the size of scripts. I recently attempted to search for articles and couldn’t find a consolidated  list of the main loadrunner parameters and their usage.So decided to compile a list and write this article. This […]

Citrix Protocol on LoadRunner – Tips and Tricks Part 2

This blog is continuation to my last blog ‘Citrix Protocol on LoadRunner – Tips and Tricks Part 1’. In this article, I will discuss  more tips that can be helpful when working with the Citrix_ICA protocol and LoadRunner. Number of vusers per LoadGenerator Machine: A LoadGenerator machine can run only a limited number of Citrix […]

Citrix Protocol on LoadRunner – Tips and Tricks Part 1

Citrix Logo Loadrunner

In this article, I am going to highlight some tips that can be helpful  to performance test engineers to effectively work on Citrix applications.  By understanding and implementing these points, script debug and test execution will be a lot easier. Points to consider while recording Citrix Vuser scripts simulate the Citrix ICA protocol communication between […]
