Ports and Adapters Architecture
summary
Shows a concrete Java example: a minimal tax calculator example wired from ports (interfaces) to adapters (JPA-like repo stub returning 15) and run as a small app in IntelliJ, demonstrating that domain code stays framework-free while infrastructure implements ports. Tests include fast unit tests on pure domain logic and an end-to-end Gherkin/Cucumber suite that Cucumber acceptance test passes. Discusses Spring/Quarkus, Testcontainers, Kafka/RabbitMQ, DTO anti‑corruption and transaction patterns.
