Introduction Creating complex performance testing scenarios in JMeter can be a complicated but necessary problem you will encounter as you build tests to mirror real user behaviour in your testing. There are many add-ins that can support you in the creation of these scenarios. Which is good if they do what you want them to do.

Introduction The Beanshell Interpreter in JMeter can act as a server which as stated in the JMeter documentation is accessible by telnet or http. So what, I hear you say, well this can be useful and we will explore some of these uses in this Blog Post. Before we move on the definition of a Beanshell can be found on the official Web Site.

This blog post is a tutorial for writing Gatling scripts to load test web applications. It follows our first getting started with Gatling simulation scripts article. The application under test is a fake e-commerce. We are going to create a Virtual User that browses articles in this shop. To create a dynamic load test we will cover several topics.

Gatling is a load testing tool for measuring the performance of web applications. As such, it supports the following protocols: HTTP, WebSockets, Server-sent events. Other protocols are also supported either by Gatling itself (like JMS) or by community plugins. Gatling load testing scenarios are defined in code, more specifically using a specific DSL. This guide focuses on the basics of writing a simulation to test an HTTP application: OctoPerf’s sample PetStore.

In December, we updated OctoPerf to use the latest JMeter version. Although, as a minor version, it doesn’t bring a lot of new features, it is always better to stay up to date with the latest bugfixes. We had to implement a small change in OctoPerf because JMeter now properly enforces the cache control headers in every situation. To avoid any confusion, cache control headers have now been disabled by default in OctoPerf.

Kraken is a load testing IDE based on Gatling. As such, Kraken provides a complete development environment to software programmers and load testers that seek to make the most out of Gatling.

When we consider performance testing most of the focus of the approach is placed on the script creation activity and making sure that requirements are covered, these are very important parts of your performance testing approach but so is the Test Execution. The frequency at which you run your tests is important and can save you time and effort in your script maintenance. A good performance testing execution strategy gives you the maximum amount of benefit it can by finding performance issues early.

Improvements Modular design One of the things we always wanted to handle in OctoPerf is modular design. In JMeter you can use test fragments. So far when you imported fragments in OctoPerf their content was just duplicated over the original Include controller or Module controller. But now not only can you import your modular design from JMeter but you can also create it directly in OctoPerf.

Reactive programming is a programming paradigm aimed at maintaining overall coherence by propagating changes from a reactive source (modification of a variable, user input, etc.) to elements dependent on this source.

This article follows our first blog post related to Kraken’s deployment on Kubernetes. It is a step by step guide explaining how to deploy the InfluxDb/Telegraf/Grafana stack used to generate load testing reports on Kraken.
