Limits and good practices
Good practices
- Use realistic test values when validating forms, exports or API payloads.
- Keep real customer, banking and production secrets out of public tools.
- Check the output format before copying it into a production workflow.
- Document whether a value is generated, validated, converted or only estimated.
Common mistakes
- Confusing valid format with real-world validity
- A generated or locally validated value can match a format without proving that it exists in an official system.
- Using real production data
- Public utilities are best for test data, demos, fixtures, QA and quick checks, not for confidential values.
