Häufige Annahme
Rack::Test::UploadedFile automatically infers the MIME content type from the file extension when the content_type argument is omitted.
So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.
Contract
- 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
