よくある思い込み

Faraday::NestedParamsEncoder.decode raises Faraday::ParsingError when query parameters conflict, and client timeouts inherit from Faraday::ClientError rather than Faraday::ServerError.

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

• Faraday::NestedParamsEncoder.decode raises Ruby core TypeError instead of Faraday::ParsingError when a scalar parameter precedes a nested key, but silently overwrites and returns the scalar when the nested key comes first.
• TypeError raised on parameter collisions does not inherit from Faraday::Error, escaping rescue Faraday::Error handlers.
• Faraday::NestedParamsEncoder.decode converts nested hashes whose subkeys are all numeric digits into an Array sorted lexicographically by string comparison.
• Faraday::NestedParamsEncoder.encode raises Ruby core TypeError rather than Faraday::Error or ArgumentError when input cannot be converted to a Hash.
• Faraday::FlatParamsEncoder.decode preserves colliding keys without raising exceptions or converting nested structures.
• Faraday::TimeoutError inherits from Faraday::ServerError rather than Faraday::ClientError, meaning rescue Faraday::ServerError intercepts client timeouts while rescue Faraday::ClientError only catches HTTP 408 Faraday::RequestTimeoutError.
• Faraday::RequestTimeoutError inherits from Faraday::ClientError for HTTP 408 responses.
• Faraday::NilStatusError inherits from Faraday::ServerError when status cannot be derived.
• Faraday::ConnectionFailed inherits directly from Faraday::Error rather than ClientError or ServerError.
• Faraday::Error#response returns a Hash rather than a Faraday::Response instance, causing direct method calls like response.status to raise NoMethodError.
