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.

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.

Almost every business today runs online. The internet is one of the easiest avenues for businesses to reach users, and websites are a great way to impress your customers.

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.

Regression testing is the process of verifying that if a change is made in one component of the product, the other components of the product continue to behave like it was before. It is a means to ensure that change in one functionality of the product doesn’t result in unintentional changes in other functionalities of the product.

This is a proud day for all of us here at LoadImpact! Today is the day we're unveiling the new k6 Cloud service.

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.

The Swift Package Manager allows you to create standalone Swift applications both on Linux and macOS. You can build and run these apps and you have the ability to write unit tests for your codebase. Xcode ships with the XCTest framework, but you may not know that this is an open-source library. It's available on every single platform where you can install Swift.

At the end of the year, I like to look back at what new discoveries I've made and lessons I've learnt as a QA engineer. 2019 has proved to be a bonanza year, with some startling changes in direction for Test and with new technologies and methodologies making a break into the mainstream.

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.

Artificial intelligence works on the principle of human intelligence. The machines are programmed in such a way that they think like humans and can imitate our actions. They can be designed to execute all types of tasks from complex to simple ones. The primary task machines can perform are learning, reasoning and perception.
