API-First! Contract-First! Make API development great again!
summary
Shows an automatic OpenAPI endpoint validation workflow that generates a Spring Boot backend and an Angular client from a single YAML/JSON spec, wires them to MongoDB in Docker, and runs integration tests that fail when the spec and code diverge. Uses the OpenAPI generator to produce models/controllers and an Atlassian request-validator (RestAssured module) plus an Express validator and Mocha on the front end; demo builds, runs, and demonstrates tests failing and then passing after fixing either spec or code.
