Load Testing

Simple Way to Create Complex JMeter Scenarios

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.

Load Testing Your API with Swagger/OpenAPI and k6

Throughout the years, there has been many attempts to devise a universal format for defining Web API specifications. The objective was (and still is) to help stakeholders of the system to work with those APIs, without having access to the source code. Each new "universal" format came with the promise of being ubiquitous and all-encompassing, but eventually faded away due to various reasons, like OData and WSDL.

Gatling: Simulation Scripts Parameterization

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.

How to generate a constant request rate in k6?

There are two different categories of tools in the load testing ecosystem. The first category is called non-scriptable tools and are usually used for load testing either a single endpoint or a set of endpoints. These tools usually generate load using a constant rate, which is measured in requests per unit of time, usually seconds. These non-scriptable tools don't apply any logic to the load testing process, other than the generation of load.

Gatling: Getting Started With Simulation Scripts

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.

Open source load testing tool review 2020

It has been almost three years since we first published our first comparison & benchmark articles that have become very popular, and we thought an update seemed overdue as some tools have changed a lot in the past couple of years. For this update, we decided to put everything into one huge article - making it more of a guide for those trying to choose a tool.

How GitLabs QA team leverages GitLab's performance testing tool

We’ve set up several initiatives aimed at testing and improving the performance of GitLab, which is why the Quality team built a new tool to test GitLab's performance. Performance testing is an involved process and distinct from other testing disciplines. The strategies and tooling in this space are specialized and require dedicated resources to achieve results.

LoadImpact is rebranding to k6

This is a proud day for all of us here at LoadImpact! Today is the day we're unveiling the new k6 Cloud service. A completely rebuilt frontend to our cloud service including some much requested improvements. Today is also the day when we make public our plan to rebrand the company as "k6", the starting point for the transition away from the "LoadImpact" brand and loadimpact.com to the "k6" brand and k6.io.
