WMS Testing Patterns

<default_to_action> When testing Warehouse Management Systems:

1. VALIDATE inventory accuracy (receipt, putaway, cycle count, adjustments)
2. TEST pick/pack/ship workflows end-to-end (wave release -> shipment confirm)
3. VERIFY EDI message processing (856 ASN, 940 Order, 945 Confirmation, 943/944 Stock)
4. ASSERT RF/barcode scanning flows (scan -> validate -> update -> confirm)
5. EXERCISE allocation and replenishment logic (FIFO, FEFO, lot control)
6. TEST WMS-ERP integration (inventory sync, order status, goods receipt)
7. VALIDATE wave management (wave planning, release, short-pick handling)

Quick Pattern Selection:

• Inventory discrepancies -> Cycle count and adjustment tests
• Order fulfillment issues -> Pick/pack/ship workflow tests
• EDI failures -> Message format and acknowledgment tests
• Scanning problems -> RF device simulation tests
• Allocation errors -> Lot control and FIFO/FEFO tests
• Integration gaps -> WMS-ERP sync boundary tests

Critical Success Factors:

• WMS accuracy directly impacts customer experience and financial reporting
• Always test both normal and exception flows (short picks, damaged goods, returns)
• EDI testing must cover both syntax validation AND business rule validation </default_to_action>

Quick Reference Card

When to Use

• Testing WMS platforms (Blue Yonder/JDA, Manhattan Associates, SAP EWM, Oracle WMS)
• Validating inventory transaction accuracy (receipts, picks, adjustments)
• Testing EDI document exchange (X12 856/940/945/943/944, EDIFACT DESADV/ORDERS)
• Verifying RF/mobile scanning workflows
• Testing wave management and allocation logic
• Validating WMS-to-ERP integration (SAP MM/WM, Oracle)
