Contract-Based Testing for Microservices and UI
summary
Describes a Pact consumer‑driven contract testing pipeline using a Pact Broker and provider verification in CI, with mock servers for isolated service tests and real Oracle/Postgres/Elastic databases in setup. The pipeline runs Dockerized tests in parallel (about 20 threads) to run ~1000 fast component tests and ~60 end-to-end checks across ~34 microservices in ~15 minutes, includes client‑side performance checks, achieved near‑100% pass targets and reduced testers to one per 62 developers, while noting it requires engineering effort and cross‑team agreement.
