We've had a bit more experience performance testing with k6 since we first covered it in the Radar, and with good results. Our teams have enjoyed the focus on the developer experience and flexibility of the tool. Although it's easy to get started with k6 all on its own, it really shines with its ease of integration into a developer ecosystem. For example, using the Datadog adapter, one team was quickly able to visualize performance in a distributed system and identify significant concerns before releasing the system to production. Another team, with the commercial version of k6, was able to use the Azure pipelines marketplace extension to wire performance tests into their CD pipeline and get Azure DevOps reporting with little effort. Since k6 supports thresholds that allow for automated testing assertions out of the box, it's relatively easy to add a stage to your pipeline that detects performance degradation of new changes, adding a powerful feedback mechanism for developers.
