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.

What “done” looks like

The integration demonstrates correctness, security boundary enforcement, and operational visibility with audit-grade evidence. Deviations are documented with approval and risk acceptance.

Recommendation: run UAT with both request-submitter and provider stakeholders present to validate CAS resolution, internal API delivery, lifecycle events, and ownership boundaries.

Coverage areas

UAT must validate both the technical integration and the operational governance surfaces.

Functional

Payment-request intake, CAS Resolver and CAS V2 FinAddress resolution, provider delivery, lifecycle events, and state transitions.

Security

Bearer and internal-key authentication, CAS participant identity and TLS, idempotency, lifecycle deduplication, and boundary rejection.

Reliability

CAS token refresh, timeouts, retries, duplicate deliveries, and recovery behavior.

Enablement portal

Access review, credential lifecycle, UAT evidence, and operator accountability outside Core.

Negative testing

Invalid credentials, unknown or inactive alias, route mismatch, malformed payloads, and illegal lifecycle transitions.

Partner workflow

Workspace access, artifacts/downloads, and readiness gates.

Suggested flow

A structured sequence that reduces rework and keeps evidence defensible.

1
Prepare environment + provider route
Confirm sandbox/UAT setup, roles, credentials, CAS Resolver mode, CAS participant identity and test data, provider route, and adapter configuration.
2
Execute baseline happy paths
Resolve payer and payee, select active financial-address options, submit their opaque IDs, verify adapter delivery to the provider API, and confirm lifecycle events.
3
Run security + negative cases
Validate boundary enforcement and explicit rejection behavior.
4
Confirm visibility alignment
Ensure operator views and partner views match runtime outcomes.
5
Sign-off + readiness gate
Record evidence, resolve defects, and complete approval for production enablement.

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.

High-priority functional cases pass

No open functional defects that block core flows.

Security-critical cases pass

Authentication, boundary rejection, idempotency, event deduplication, and transition controls behave correctly.

No unresolved critical defects

Critical severity issues are closed or formally waived with approval.

Provider lifecycle confirmed

Provider events are correct, timely, and retry-safe across intermediate and terminal states.

Runtime configuration is traceable

The approved provider route and adapter snapshot used by Core can be correlated with execution evidence.

Sign-off recommendation

Final sign-off should include operator approval, partner confirmation, and recorded evidence links for audit traceability.
