Häufige Annahme

Passing converters: :numeric parses numeric strings with leading zeros as decimal numbers or preserves them consistently as strings.

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

• CSV.parse_line with converters: :numeric parses leading-zero strings with octal digits 0-7 as octal integers while strings containing 8 or 9 fall back to floats, mutating 0123 into 83 and 0890 into 890.0 across a round trip
• assert CSV.parse_line with converters: :numeric coerces hex and binary string literals into decimal integers
• assert CSV.generate_line with a single nil element emits an empty line that CSV.parse_line reads as an empty array of length zero
• assert CSV.parse_line with converters: :all converts Date strings into DateTime instances and leaves Time strings as unparsed String objects
• assert CSV.parse_line with unconverted_fields: true retains the original string representations on the unconverted_fields attribute
