Microservice Matchmaking: Pact Testing Between Spring Boot and gRPC
summary
Shows how Pact links a Spring Boot REST consumer to a .NET gRPC provider by generating a protobuf descriptor set, pushing consumer contracts to a Pact Broker, and running provider verification that produces a Can I Deploy result. Live demo exercises contract creation, provider stubbing and CI gating but hit Docker broker flakiness. Practical pitfalls: Pact v4 plugins need a version workaround, proto default values require extra test branches, and gRPC needs TLS or HTTP2 transport setup for reliable verification.
