Test-Driven Development: It's easier than you think!
summary
A demo builds a small Java 21 Quarkus app (REST + JPA + Hibernate + PostgreSQL) using Quarkus Dev Services to auto-start a Postgres container and Continuous Testing to rerun only affected tests; repository and resource layers get unit and integration coverage with Mockito, AssertJ and REST-assured. Tests start failing, code is implemented until they pass, and an AI-assisted scaffolding step produces a working resource class from incomplete test stubs. Kafka is sketched but omitted for time; the demo compiles and tests turn green.
