How Open‑Source Tools Enable Scalable Microservice Performance Testing
The article examines why traditional JMeter‑based load testing falls short for microservices and presents a four‑layer open‑source stack—Gatling, k6, Prometheus/VictoriaMetrics/Grafana + Pyroscope, and Chaos Mesh/LitmusChaos—plus a 3C methodology and automated closed‑loop workflow to achieve observable, programmable, and resilient performance testing in cloud‑native environments.
