Од 2017Modern load testing
Modern load testing — developer-friendly performance testing with JavaScript, real-time metrics, and CI/CD integration.
Преглед
k6 is my load testing tool of choice. I write performance tests in JavaScript that simulate realistic user scenarios — API endpoints, authentication flows, database-heavy operations. I define thresholds for response times, error rates, and throughput. Integrated into CI/CD for automated performance regression detection. Results exported to Grafana for visualization.
