Häufige Annahme

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.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• 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
