Format and field rules
Format validation checks required fields, length, characters, and structure. Regional consistency checks whether city, state, and ZIP Code plausibly match.
Delivery verification requires an authoritative address service to confirm a building and delivery point. Random Address Generator supplies the first two test layers, not a delivery result.
Recommended test cases
Cover normal input, boundary input, and deliberately invalid input as separate cases.
- Assert format errors and regional errors separately
- Do not label a format pass as deliverable
- Handle timeout and no-result states from an external verification service
Scope
This guide explains development-test formatting. It does not provide a delivery, identity, or payment verification result.
