よくある思い込み

JSON.parse! is an exception-raising strict mode of JSON.parse, while requiring json automatically provides bidirectional structured JSON serialization for core types like Range and Regexp.

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• assert JSON.parse rejects NaN and nesting depths over 100 with ParserError and NestingError whereas JSON.parse! relaxes limits to allow NaN and unbounded nesting by default
• assert core types like Range, Regexp, Complex, and Rational require explicit json/add modules to serialize as json_class additions and reconstruct via create_additions
• assert JSON.generate passes a JSON::State instance to custom to_json methods raising ArgumentError on arity-zero definitions unless state arguments are forwarded
• assert JSON::State enables custom whitespace and ASCII formatting while pretty_generate formats with newlines and fast_generate bypasses depth checks
