Build resilient systems with Spring Cloud Contract and Testcontainers

on YouTube ↗52m

" summary

Example GitHub repo demonstrates a coffee app with waiter and barista exchanging JSON via Kafka while Spring Cloud Contract generates producer tests and a stubs jar that the consumer uses for integration. Tests run against a real Kafka container provided by Testcontainers (Spring Boot 3.1 service-connection wiring), the generated verifier initially fails on a broken producer then passes after fixes, and artifacts (app + stubs) install to local Maven for pipeline and local development use.
