Lo que suele suponerse

JSON.generate and JSON.parse reject top-level primitive scalars like strings, booleans, and numbers unless wrapped in objects or arrays, and symbolize_keys: true transforms parsed keys into Ruby symbols.

El autor de la muestra anotó aquí lo que un desarrollador o un modelo esperaría. El contrato de abajo es lo que realmente se ejecutó.

Contrato

• assert JSON.generate and JSON.parse serialize and deserialize top-level primitive strings, numbers, booleans, and nil directly without quirks mode, while symbolize_keys is silently ignored leaving string keys unless symbolize_names is used
• assert JSON.load with an empty string returns nil via default allow_blank but raises JSON::ParserError on non-empty whitespace, whereas JSON.parse raises JSON::ParserError on both
• assert JSON.dump with an IO destination writes the payload and returns the IO instance itself rather than the generated JSON string
• assert JSON.dump depth limit violation raises ArgumentError whereas JSON.generate depth limit violation raises JSON::NestingError
• assert JSON.dump with keyword arguments like indent raises ArgumentError for unknown keywords instead of configuring pretty printing
