Payment Methods integration suite

Verification Boundary

The suite exercises books configuration against the migrated local database. Its fixtures and transaction contexts determine the records and service paths under test.

What This Suite Proves

The individual assertion references identify the acceptance outcomes this file exercises. When a scenario spans several suites, this file supplies only its listed assertions; qualification must include the other bindings and any recorded coverage finding.

What It Does Not Prove

Local database execution does not prove deployed infrastructure, external provider availability or console behavior. No result is claimed for the pinned revision until the suite runs and its evidence is reviewed.

Real Dependencies and Test Doubles

PostgreSQL, migrations and the exercised persistence paths are real. Test-owned execution contexts, clocks and local Platform records supply deterministic setup; the file’s imports and fixtures identify any additional doubles.

Must Not Be Doubled

The database constraints, transaction paths and production persistence functions named by the assertions must remain real. A memory store cannot establish the recorded database proof.
