Streamlining Cloud-Native Development: Simplifying Dependencies and Testing with Microcks
summary
Combines Microcks + Testcontainers with Quarkus Dev Services to automatically spin up lightweight containered mocks from OpenAPI/AsyncAPI/Postman artifacts, producing REST, gRPC and Kafka-style messages so local devs get real networked behavior and contract tests inside Quarkus tests. Demo builds an order service using a catalog API and CFA payment events, starts in milliseconds with ~10–20 MB footprint, and the simulated endpoints and continuous contract checks work end to end.
