Promotion Codes Verification

Verification Boundary

The composed API handler runs locally with signed caller contexts and the integration database. Its route, mapping, permission and persistence assertions establish the local API boundary.

What This Suite Proves

The promotion codes assertions contribute to the scenarios listed in the register. Each binding retains its exact source test anchor so a reviewer can distinguish an individual contribution from the complete scenario.

What It Does Not Prove

The register records source inspection only. It establishes no run result, delivery qualification or Product approval.

Real Dependencies and Test Doubles

PostgreSQL and the services called by the suite are real. External service ports, file storage and queues may use the fixtures declared by the suite and its support helpers.

Must Not Be Doubled

Keep the asserted database constraints, transactions, service functions and execution contexts real. For API suites, preserve the dispatcher and permission enforcement.
