This article is the fourth part of a series of tutorials dedicated to Gatling Load Testing. Kraken is used to ease the debugging of Gatling simulations and to speed up the process of load testing a fake e-commerce website: PetStore. We will focuse on POST requests and script modularization: In the previous blog post we created a realistic Virtual User that browses the store without buying anything.

Before the release of k6 v0.27, there was insufficient support for generating constant request rates. Therefore, we introduced a JavaScript workaround by calculating the time it takes for requests to exhaust each iteration of the script. This v0.27 release includes a new execution engine and lots of new executors that cater to your specific needs. It also includes the new scenarios API with lots of different options to configure and model the load on the system under test.

k6 v0.27.0 is finally out! It has been over a year since the k6 team started working on this release, which includes a multitude of new features, improvements, bugfixes and beyond. This release was an effort to redefine performance and load-testing in k6, by introducing a new execution engine and lots of new executors on top, along with the most requested feature, scenarios. It also includes many UX improvements and bugfixes.

This third version of Kraken represents one more step towards a load testing solution suitable to teams and enterprises. Kraken can already be installed on your own Kubernetes cluster thanks to Helm charts: You own all data and can handle the security inhouse. But until now it was lacking users management, making it cumbersome to use it for a team of performance testers. This point is now addressed in the version 3.0 thanks to Keycloak.

OctoPerf’s report engine provides many graphs to sort and presents test metrics in a comprehensive way. We’ve tried to improve it over the years so that you can access critical information very quickly. But requirements vary from one project to the other. In this post we will look at how you can configure the report to show you preferred metrics, and also all the shortcuts you can take to achieve this goal.
