Integration Testing Strategy for SAP Landscapes

Keep this: job aid

Integration test strategy card

• Levels: mapping and component, contract, interface to stub, connected SIT, end-to-end, error/volume/recovery, operational.
• Set depth per interface by business impact and technical complexity; write it down.
• Mapping tests: every field, multi-item, boundaries, value-mapping gaps, empty fields, character sets.
• Expected results from the specification, never from the code under test.
• Version contracts (IDoc types, XSDs, OpenAPI) and shared samples; rerun on any change.
• Connected SIT: book partner windows early, agree shared test data, enforce entry criteria.
• Daily joint triage with shared message IDs; book retests before the window closes.
• Error tests check five things; volume tests use production peaks and sizes; recovery shows no loss, no duplicates.
• Operational proof: alerts to owners, reprocessing by operators, reconciliation finds a planted gap.
• Report readiness per interface and level with linked evidence; owners sign residual risk.
