The Function Test Double Framework is presented as ABAP Unit's way of testing code that calls a function module — procedural, without a class's native test-double support — without triggering the database, RFC or BAPI calls the real function module would make.","short":"Replacing function modules with test doubles in ABAP Unit","author":"Jagadish_R31","published":"2026-06-01","provenance":{"discovered_via":[{"source":"source:sap-community","channel":"abap-development-tag"}],"first_seen":"2026-09-14"},"drafted_with_ai":true,"published_on":"source:sap-community"},"readings":{"liveness":[{"label":"Checked against the source","tier":"unknown","evidence":"nobody has checked it"},{"label":"Source reachable","tier":"unknown","evidence":"not crawled"},{"label":"Age","tier":"good","evidence":"published 4 months ago"}],"compatibility":[{"label":"Version","tier":"unknown","evidence":"no version declared"},{"label":"Moved since?","tier":"good","evidence":"no recorded change after 2026-06-01"},{"label":"Findings","tier":"good","evidence":"none flagged"}],"reach":[{"value":584,"unit":"views"},{"value":1,"unit":"comments"},{"value":4,"unit":"likes"}]},"signals":{"views":584,"likes":4,"comments":1,"metrics_at":"2026-10-25"},"series":null,"edges":{"authors":[]}}
