흔히 이렇게 알고 있다

Rack::Test::UploadedFile automatically infers the MIME content type from the file extension when the content_type argument is omitted.

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

컨트랙트

• Rack::Test::UploadedFile.new with an image file path returns 'text/plain' for content_type rather than 'image/png' when the argument is omitted, because UploadedFile defaults content_type to 'text/plain' without inspecting the filename extension.
• assert posting an UploadedFile without an explicit content_type sends 'content-type: text/plain' in the multipart body and parses into params with :type 'text/plain'
• assert passing an explicit content_type argument overrides the default and preserves 'image/png' in both UploadedFile and multipart params
• assert UploadedFile wrapping a StringIO defaults content_type to 'text/plain' when content_type is left unset
• assert Rack::Test::Session defaults default_host to 'example.org' rather than 'localhost' when initialized without an explicit host
