흔히 이렇게 알고 있다

A competent developer expects bare query flags `?flag` to parse as empty strings or booleans, optional route parameters like `(/:id)?` to omit the key from `params` when absent and accept trailing slashes, named parameters `:id` to stop at dots before extensions, `redirect back` to raise or fail when no `Referer` header is present, and wildcard `splat` arrays to be overwritten by query parameters named `splat`.

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

컨트랙트

• assert an omitted optional route parameter in (/:id)? populates params[:id] as nil with params.key?('id') true while trailing slash /users/ returns 404, bare query flags parse as nil rather than empty strings, and named route params capture across dots
• assert named route parameter :filename captures the entire dotted string archive.tar.gz whereas :name.:ext splits at the final dot
• assert route wildcard splat arrays take precedence over conflicting ?splat query parameters and remain arrays
• assert bare query parameter ?bare yields nil while ?empty= yields empty string and ?count=0 yields string '0'
• assert redirect back without HTTP_REFERER silently redirects to root / with status 302 rather than raising an error
• assert UTF-8 routes and percent-encoded multibyte emoji parameters match and decode into valid UTF-8 encoded strings
• assert status 204 No Content suppresses the returned string body and strips Content-Type and Content-Length headers
