Short answer
Bacs Direct Debit testing covers AUDDIS submission, collection submission, ADDACS, AUDDIS responses and ARUDD handling — across the full 3-day Bacs cycle.
What this actually means in practice
Build a test SUN environment, submit every AUDDIS reason code, exercise every ADDACS reason, and validate that ARUDD records reconcile cleanly against your ledger. Include schedule edge cases (bank holidays, month-end) and customer comms.
The most common pitfall
Skipping ARUDD handling and discovering reconciliation breaks only at month-end.
What to do next
Get an independent test pack covering every AUDDIS/ADDACS/ARUDD reason code.
