Contract

  1. SnapshotFormat provides the JSON schema definition for Jest snapshot options
  2. validateSnapshotFormat validates compliant snapshot formatting options including indent and theme
  3. validateSnapshotFormat accepts empty configuration as all SnapshotFormat options are optional
  4. validateSnapshotFormat rejects invalid option types and negative indentation values
  5. validateSnapshotFormat rejects unrecognized top-level and nested theme properties
