Format and field rules
Test records should be easy to identify in logs and databases. Use example.com emails, recognizable phone patterns, and a consistent environment prefix.
Use fixed seeds or saved fixtures for reproducible tests, and random data for exploratory work. Clean records by environment label after the run.
Recommended test cases
Cover normal input, boundary input, and deliberately invalid input as separate cases.
- Cover valid, boundary, invalid, and duplicate records
- Avoid copying production customer records
- Verify cleanup scripts cannot delete production data
Scope
This guide explains development-test formatting. It does not provide a delivery, identity, or payment verification result.
