Testing guides

Practical guides to address formats, fixture preparation, and this tool’s real behavior.

A practical checklist for testing an address form

Build positive, negative, and boundary cases from a small set of synthetic address records.

Check regional selection and application state without turning an example address into a tax determination.

Use exploration to discover useful cases, then save explicit fixtures for repeatable assertions.

Distinguish geographic reference data, a generated street, and a verified delivery destination.

Keep development fixtures useful, minimal, and separate from production customer records.

Keep structured fields intact and test presentation without assuming that formatting establishes delivery.

Check display labels, stored values, District of Columbia handling, and region changes.

Build regional checkout scenarios with controlled expected results and clearly defined responsibilities.
