흔히 이렇게 알고 있다

A shelf Cascade cascades to subsequent handlers on any 4xx or 5xx client or server error response by default.

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

컨트랙트

• Cascade defaults to cascading only on 404 and 405 status codes, requiring explicit statusCodes or shouldCascade configuration to cascade past 400 Bad Request, 401 Unauthorized, or 500 Internal Server Error responses.
• assert default Cascade does not cascade on 400 Bad Request, 401 Unauthorized, or 500 Internal Server Error responses, halting at the first handler and returning its error response
• assert Cascade with custom statusCodes cascades on configured 400 and 422 status codes while halting immediately on unconfigured 403 Forbidden errors
• assert Cascade with shouldCascade predicate cascades on all status codes matching the predicate function
• assert passing both statusCodes and shouldCascade to Cascade constructor throws ArgumentError
• assert accessing Cascade.handler on an empty Cascade without inner handlers throws StateError
