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.
