Testing CAP and BTP Extensions

Keep this: job aid

BTP extension test plan checklist

• Map each failure type to the cheapest level: service, UI, contract, integration, end-to-end.
• cds.test first in every test file; runner-agnostic tests; reset data per test.
• Test every rule and role positive and negative; never stub the CAP service itself.
• Mock remote services with realistic .csv data; keep failure mocks separate.
• Record a narrow contract per consumed API and event; check it in the pipeline and against CMQ after each support package.
• QUnit for UI logic, OPA5 for screens against mock data; browser end-to-end only for cross-app journeys.
• Run a readiness check before end-to-end; wait for conditions, never fixed times.
• Quality gates on every step; flaky tests are defects.
• Evidence package for the exact version going live, recorded in SAP Cloud ALM.
