Logistics platforms exchange EDI messages and API calls with shippers, carriers and warehouses. Each message type needs tests for structure, content and sequence.
Message types and what to check
| X12 set | Purpose | Structure checks | Content and sequence checks |
|---|---|---|---|
| 204 | Motor carrier load tender | Segments and loops per partner guide | Stops, references and equipment match the shipment |
| 210 | Freight invoice | Totals and charge segments | Amount equals the price the TMS calculated; duplicate invoice handling |
| 214 | Shipment status | Status codes and timestamps | Events out of order, missing, repeated |
| 856 | Advance ship notice | Hierarchical levels (shipment, order, pack, item) | Quantities match the pick and pack data |
| 940 | Warehouse shipping order | Line items and addresses | Order creates the right WMS task |
| 945 | Warehouse shipping advice | Shipped quantities | Confirms against the 940 that triggered it |
Definitions of each set are on the X12 transaction set list in the sources.
Carrier API contract checks
Pin the contract (OpenAPI or the carrier's schema), test every required field, invalid values and rate limits, and record responses so a carrier change breaks a test rather than a shipment. Test timeouts and retries; label and tracking calls often fail at peak season.
