pytest_jsonschema_snapshot.tools.genson_addon.to_schema_converter

Json → Schema with optional format handling.

format_mode options

  • "on" – detect formats and let validators assert them (default).

  • "off" – ignore formats entirely.

  • "safe" – keep the annotations but embed a $vocabulary block that

    disables the draft‑2020‑12 format‑assertion vocabulary. This makes every format purely informational, regardless of validator settings.
