흔히 이렇게 알고 있다

CSV::InvalidEncodingError inherits from Ruby core's EncodingError, and liberal_parsing: true suppresses unclosed quote errors.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• CSV::InvalidEncodingError inherits from CSV::MalformedCSVError and RuntimeError rather than EncodingError, so rescue EncodingError fails to catch byte sequence errors during parsing.
• assert CSV.parse with invalid byte sequences raises CSV::InvalidEncodingError reporting the 1-based line_number
• assert CSV.parse and CSV.parse_line raise ArgumentError with message 'Cannot parse nil as CSV' when passed nil
• assert CSV.parse_line on an empty string returns nil whereas CSV.parse returns an empty array
• assert CSV.parse with liberal_parsing: true allows unescaped quotes but still raises CSV::MalformedCSVError on unclosed quotes
• assert CSV::MalformedCSVError inherits from RuntimeError and attaches line_number on parse errors
