常见的想当然

CSV.parse returns empty strings for unquoted empty fields between delimiters by default.

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

• assert parsing unquoted empty fields returns nil rather than empty string when nil_value is left unset
• assert parsing quoted empty fields returns empty string governed by the default empty_value option
• assert CSV::DEFAULT_OPTIONS configures nil_value as nil and empty_value as empty string
• assert passing nil_value: '' normalizes unquoted empty fields to empty strings
• assert header indexed access yields nil for unquoted empty columns by default
