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)

Testing Levels

Critical Test Scenarios

Tools

• WMS Platforms : Blue Yonder WMS, Manhattan WMOS, SAP EWM, Oracle WMS Cloud
• EDI Testing : Bots EDI, SPS Commerce Test, Cleo Clarify
• RF Simulation : Custom RF emulators, Zebra SDK test harnesses
• Integration : SAP PI/PO, MuleSoft, Dell Boomi
• Monitoring : Splunk, WMS dashboards, EDI tracking portals

Agent Coordination

• qe-middleware-validator: WMS-ERP integration flows and message transformation validation
• qe-contract-validator: EDI document contracts and WMS API contracts
• qe-sap-idoc-tester: WMS-SAP IDoc validation (WMMBID01, SHPCON)

Best Practices

Do This

• Test the complete lifecycle: receive -> putaway -> allocate -> pick -> pack -> ship -> EDI
• Validate inventory accuracy at every state transition (on-hand, allocated, in-transit)
• Test all allocation methods for your WMS (FIFO, FEFO, LIFO, zone priority)
• Simulate RF device failures mid-transaction (battery death, WiFi drop, scan timeout)
• Validate EDI acknowledgments (997) for every outbound document
• Test short-pick, over-pick, and wrong-pick scenarios explicitly
• Verify WMS-ERP sync latency against SLA thresholds
• Test cycle count variance at multiple thresholds (auto-approve, supervisor, recount)

Avoid This

• Testing only happy-path receiving without over/under tolerance scenarios
• Skipping RF error flows (wrong scan, timeout, connectivity loss)
• Ignoring EDI segment-level validation (trusting document-level pass)
• Testing allocation logic without expired lot scenarios
• Assuming WMS-ERP sync is instantaneous; always test with timing assertions
• Deploying without testing wave planning with mixed priority orders
• Ignoring cartonization and weight validation in pack verification

Agent Coordination Hints

Primary Agents

• qe-middleware-validator : WMS-ERP integration flow testing and message transformation validation
• qe-contract-validator : EDI document contract testing and WMS API contracts

Supporting Agents

• qe-message-broker-tester : When WMS uses message queues for async processing
• qe-odata-contract-tester : When WMS exposes OData services (SAP EWM)
• qe-sap-idoc-tester : When WMS-SAP integration uses IDocs (WMMBID01, SHPCON)

Coordination Pattern

1. qe-contract-validator -> Validate EDI document schemas and segments
2. qe-middleware-validator -> Test WMS message flows and transformations
3. qe-message-broker-tester -> Verify async queue processing and DLQ
4. qe-odata-contract-tester -> Test WMS OData APIs (if SAP EWM)
5. qe-sap-idoc-tester -> Validate IDoc structure and content

Memory Namespace

Fleet Coordination

const wmsFleet = await FleetManager.coordinate({
  strategy: 'wms-testing',
  agents: [
    'qe-contract-validator',     // EDI contracts and API contracts
    'qe-middleware-validator',    // WMS-ERP message flows
    'qe-sap-idoc-tester',        // IDoc validation
    'qe-odata-contract-tester'   // SAP EWM OData testing
  ],
  topology: 'mesh'
});

await wmsFleet.execute({
  workflows: [
    { name: 'inbound', stages: ['receive', 'putaway', 'inventory-sync'] },
    { name: 'outbound', stages: ['wave', 'pick', 'pack', 'ship', 'edi-856'] },
    { name: 'returns', stages: ['rma-receipt', 'inspection', 'disposition'] }
  ],
  testEdi: true,
  testRfScanning: true,
  testAllocation: true
});

QCSD Integration

• Ideation : Flag HAS_WMS triggers WMS-specific quality criteria (inventory accuracy, EDI compliance)
• Refinement : SFDIPOT includes warehouse operations product factors (throughput, accuracy, latency)
• Development : Coverage analysis includes EDI document parsing paths and allocation algorithms
• Verification : Pipeline gates include WMS integration health checks and EDI acknowledgment validation

Remember

Warehouse Management Systems are the physical-digital bridge. When inventory is wrong, customers get wrong shipments, financial reports are inaccurate, and replenishment fails. Test every inventory state transition, every EDI document field, and every RF scanning exception. A 2% inventory variance might seem small until it compounds across 100,000 SKUs in 50 warehouses.

With Agents: Agents validate EDI document structures segment-by-segment, test WMS-ERP sync within SLA thresholds, and simulate RF scanning workflows at scale. Use agents to cover the combinatorial explosion of allocation methods, lot control scenarios, and EDI error conditions that manual testing cannot reach.
