よくある思い込み

Passing a Hash payload to Rack::Test request methods with a JSON Content-Type header automatically serializes the body as JSON.

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• assert posting a Hash with application/json Content-Type sends a form-urlencoded query string and fails JSON parsing unless explicitly passed as a serialized JSON string
• assert primitive Hash parameter types are coerced to strings, nil is preserved as nil, empty arrays mutate to an array containing an empty string, and empty hashes are omitted from params
• assert URI query string and params Hash merge overwrites scalar keys but appends array elements together
• assert UploadedFile triggers multipart encoding with symbol-keyed descriptor hashes while unwrapped IO objects are stringified into urlencoded form data
• assert CookieJar silently ignores Secure cookies received over plain HTTP, filters Secure cookies from HTTP requests, and scopes non-domain cookies to the exact host
