acceptance-harness

Project information

A portable acceptance test harness for message-processing domains, built with Java 17 and Spring Boot. It models a minimal DDD flow—normalize → enrich → persist—using deterministic, synthetic fixtures and zero external dependencies. Designed for air-gapped, IL4/IL5 environments, the harness runs in under 30 seconds and produces reproducible, CI/CD-safe outputs.

Includes embedded H2 database, Spring Cloud Stream test binder (no Kafka required), and a full validation rubric via RUNBOOK.md and ACCEPTANCE_CRITERIA.md. Ideal for teams in compliance-heavy environments who need fast, auditable proof of contract adherence without SaaS reliance.

Artifacts include fixture validators, Mermaid diagrams, CI config, and acceptance screenshots. Extensible via domain events, repository interfaces, and validation specs.
