Testing

The G2P Bridge is tested at several complementary layers:

Layer	Scope	Where
Unit Testing	White-box, mocked services/DB — fast, run in CI on every commit	core/**/tests/
Functional Testing	Manual scenario testing driven from PBMS (UI flows, service-outage handling)	manual (PBMS)
Regression Sanity Suite	Black-box, point-at-a-deployed-system — every API + full end-to-end cash flow verified stage by stage, plus business-rule negatives and MT940 reconciliation errors	test/sanity/
Performance Testing	Load / throughput	test/

Use the unit tests to catch code-logic regressions, the regression sanity suite to confirm an installed environment works end to end (it now also covers the API-level negative scenarios and MT940 reconciliation-error checks that were previously standalone Postman/script artefacts), and functional (manual PBMS) and performance testing for scenario coverage and scale.
