Exploring performance with load tests
How to estimate the performance of minimal APIs? There are many points of view to consider and in this chapter, we will try to address them from the point of view of the load they can support. We decided to adopt a tool – k6 – that performs load tests on a web application and tells us how many requests per second can a minimal API handle.
As described by its creators, k6 is an open source load testing tool that makes performance testing easy and productive for engineering teams. The tool is free, developer-centric, and extensible. Using k6, you can test the reliability and performance of your systems and catch performance regressions and problems earlier. This tool will help you to build resilient and performant applications that scale.
In our case, we would like to use the tool for performance evaluation and not for load testing. Many parameters should be considered during load testing, but we will only focus on the
