UAT & certification
UAT confirms enablement, payment-request handling, CAS alias resolution, provider route selection, adapter-to-provider delivery, lifecycle events, credentials, downloads, and operator evidence before production enablement.
The integration demonstrates correctness, security boundary enforcement, and operational visibility with audit-grade evidence. Deviations are documented with approval and risk acceptance.
Coverage areas
UAT must validate both the technical integration and the operational governance surfaces.
Payment-request intake, CAS Resolver and CAS V2 FinAddress resolution, provider delivery, lifecycle events, and state transitions.
Bearer and internal-key authentication, CAS participant identity and TLS, idempotency, lifecycle deduplication, and boundary rejection.
CAS token refresh, timeouts, retries, duplicate deliveries, and recovery behavior.
Access review, credential lifecycle, UAT evidence, and operator accountability outside Core.
Invalid credentials, unknown or inactive alias, route mismatch, malformed payloads, and illegal lifecycle transitions.
Workspace access, artifacts/downloads, and readiness gates.
Suggested flow
A structured sequence that reduces rework and keeps evidence defensible.
Evidence model
Evidence must be reproducible and traceable. Use the tracker for consistent collection.
| Field | Description | Example |
|---|---|---|
| Test case ID | Unique identifier for repeatable execution. | UAT-FN-001 |
| Date executed | When the test ran. | 2026-03-26 |
| Environment | Sandbox / UAT (staging) / production-path test. | UAT |
| Outcome | Pass / Fail / Blocked. | PASS |
| Observed behavior | Notes and deviations from expected behavior. | Callback received within 3s; status transitions correct. |
| Evidence links | Screenshots, logs, tickets, correlation IDs. | JIRA-1234 / trace_id=abc |
Acceptance criteria
Readiness gates required before production enablement.
No open functional defects that block core flows.
Authentication, boundary rejection, idempotency, event deduplication, and transition controls behave correctly.
Critical severity issues are closed or formally waived with approval.
Provider events are correct, timely, and retry-safe across intermediate and terminal states.
The approved provider route and adapter snapshot used by Core can be correlated with execution evidence.
Final sign-off should include operator approval, partner confirmation, and recorded evidence links for audit traceability.
