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.
