Summary

The article explains service virtualization as a technique to replace live dependencies (APIs, databases, queues) with virtual services, enabling CI/CD–friendly testing without relying on external uptime. It covers configuration-based and traffic-capture approaches, practical examples (checkout with a virtual payment service), benefits for faster, deterministic test runs, and a Keploy-based implementation using kernel-level eBPF capture. It also situates service virtualization in the tooling landscape and discusses limitations and a maturity model.
