Consumer Driven Contracts and Your Microservice Architecture

on YouTube ↗01h 04m

" summary

Claim: treat APIs as tests by writing consumer-driven contracts that generate executable checks and runnable stubs. Uses Spring Boot, Spring Cloud Contract (Groovy DSL), the Maven/Gradle plugin to emit a stubs JAR and WireMock stubs, plus stub-runner (standalone or JUnit) to run predictable HTTP or messaging integration tests. Workflow generates JUnit tests, uncovers breaking changes (demo catches a removed X27 field), supports stateful scenarios and CI publishing of contracts.
