**Fetch the latest test suite**: Web-search `github Universal-Commerce-Protocol conformance` and fetch the README for current setup instructions, test data format, and CLI flags.
Implements UCP patterns: capability negotiation with caching, idempotency keys via Redis/DB, error resolution loops for checkouts, multi-binding REST/MCP/A2A servers. For UCP internal architecture.
Validates ACP implementations against protocol specs: schema validation, checkout flows, idempotency, error handling, security checks, production readiness. Use for compliance and launch prep.
Expert approach to contract-testing in API testing. Use when working with .

The official suite contains ~13 test files covering:
| Test File | What It Validates |
|---|---|
| Checkout lifecycle | Full create → update → complete → verify flow |
| Order management | Order creation, status transitions, data integrity |
| Fulfillment | Shipping/pickup methods, group selection, option validation |
| Card credentials | Payment credential format, tokenization |
| Webhooks | Delivery, retry, signature verification |
| Idempotency | Duplicate request handling, cache behavior |
| Invalid input | Error responses for malformed requests |
| Protocol compliance | Headers, TLS, version negotiation |
| Data validation | Schema compliance, required fields, type correctness |
| Service bindings | REST/MCP/A2A transport correctness |
| Business logic | Totals calculation, tax, discount application |
| AP2 integration | Mandate generation, signing, verification |
| Security (simulation URLs) | URL validation, injection prevention |

Tests require a conformance_input.json file that describes your store's products, prices, and expected behaviors. Check the sample test data in the repo for the format.
