Why your Performance Test Execution strategy is important

Jmeter Nov 25, 2019

Making sure your performance testing execution strategy is suitable.

Introduction 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.

OctoPerf 11 - Modular design, tags and improved administration

Innovation Oct 30, 2019

OctoPerf 11 is available, with modular design, tagging and improved user administration for our Enterprise customers.

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: A fragment virtual user can be seen as a library of functions.

Fullstack Reactive Server Sent Events

Kraken Oct 9, 2019

How to handle Server Sent Events in a Fullstack Reactive web application based on Spring WebFlux and Angular.

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. Reactive applications are more and more important today as they are: Highly Available: the system must respond quickly no matter what, Resilient: the system must always remain available, even in case of error or even if it is overloaded, Message Oriented: the system uses asynchronous messages.

Test camp 2019: OctoPerf in Poland

Events Sep 25, 2019

Our feedback on test camp conference in Wroclaw. We enjoyed the expo and the country very much and hope to see you in Prague for the eurostar!

For our first time in Poland, we decided to attend to TestCamp conference. TestCamp is an event-based in Wroclaw, Poland. Test Army is behind the organisation. This event was split in two days, the first one, we trained a few people on OctoPerf. The second one as exhibitor and speaker. More than 500 people attended on Saturday, which is quite an impressive number. OctoPerf training/workshop on Friday We dedicated our first day to train people on OctoPerf, to create a realistic script, run a test and analyze the metrics together.

How To Deploy InfluxDB / Telegraf / Grafana on K8s?

Kraken Sep 19, 2019

A step by step guide to deploying the InfluxDB/Telegraf/Grafana stack on Kubernetes. How to map configuration files, data folders, and environment variables?

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. More importantly we will se: How to map a configuration file using a ConfigMap resource? How to map sensitive environment variables using the Secrets object? How to use Kompose to generate declarative K8S configuration? how to mount a data volume with a PersistentVolumeClaim?

How To Deploy a Frontend on Kubernetes?

Kraken Sep 5, 2019

A step by step guide to deploying an Angular frontend behind an NGinx Ingress on Kubernetes. K8S installation, Ingress controller deployment and frontend application proxying.

Kraken is a load testing solution currently deployed on Docker. In order to use several injectors (Gatling) while running a load test, its next version might rely on Kubernetes. Kubernetes (commonly referred to as “K8s”) is an open source system that aims to provide a platform for automating the deployment, scalability and implementation of application containers on server clusters. It works with a variety of container technologies, and is often used with Docker.

Angular Workspaces: Multi-Application Projects

Kraken Aug 22, 2019

How to create an Angular 8 project with multiple applications and libraries? This guide uses the Kraken Load Testing IDE front as an Angular 8 workspace example.

OctoPerf’s Load Testing IDE (Kraken) is an application with two frontends: The Administration UI used to manage Docker containers and images, The Gatling UI to debug and execute load tests with Gatling. Both UI are based on Angular 8 and share many components, CSS and external library dependencies. This blog post is a guide for every developer that would like to create an Angular Workspace with several applications and libraries.

Managing data during performance testing

Jmeter Aug 8, 2019

Looking at ways of managing test data to support performance testing. From general principles to a complete example.

Introduction We are going to talk about data in this blog post, predominately test data required for performance testing. This is something that makes the life of a performance tester extremely difficult and awkward as because of the huge quantities required, in the right state, that match the criteria required for your test to run. We often have to approach the use of large quantities data for the purpose of performance testing in a number of ways:

Gradle Multi-Project Builds for Maven Users

Kraken Jul 25, 2019

How to create a multi-modules Maven project in the Gradle world? This guide uses the Kraken project as an example to help you get started with complex Gradle builds.

The creation of a Load Testing IDE (Kraken) was for me the opportunity to check on new technologies: I wanted to try another build solution for my Java backends. I used Maven for several years, both on OctoPerf and in my previous work experiences. Moving from Maven to Gradle is not necessarily easy, as the concepts involved are different This blog post is a guide for every developer with a Maven background that would like to give a try to Gradle (version 5.

Kraken: The Load Testing IDE

Kraken Jul 3, 2019

How a proof of concept on some technologies became a full-featured project: Kraken, the load and performance testing IDE.

About 8 months back, after a few years working on the same technology stack used for OctoPerf, I wanted to check if we should follow the latest trends: micro-services and reactive programming. Re-building OctoPerf with other technologies, just for a POC, seemed way too long. After all, the development of the frontend alone took me a few years, not to mention the backend … OctoPerf comes with really advanced features regarding load-testing!

OctoPerf is...
