Incorporating performance testing into the continuous integration (CI) pipeline using k6, GitHub Actions, and Grafana can significantly enhance the development process by identifying bugs earlier and improving application performance. Traditionally performed later and by separate teams, performance testing is now increasingly integrated directly into the development process, allowing for faster time to market. Matthew Churcher from Vonage demonstrated at ObservabilityCon 2021 how to embed this testing seamlessly into CI/CD pipelines, utilizing the open-source k6 tool for high-performance load testing and Grafana for result visualization. His approach involves deploying a sample app to Kubernetes, running performance tests with k6, and using Grafana Cloud to access detailed metrics and trends, which helps track and improve the application's performance over time. Churcher emphasizes setting appropriate performance thresholds to avoid unnecessary build failures and offers resources for getting started with k6, highlighting its compatibility with containerization and its cost-effectiveness.
