常见的想当然

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

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• 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
