よくある思い込み

Malformed route pattern strings raise Mustermann::ParseError on invalid capture syntax, while :ignore expansion suppresses missing parameter errors.

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

• Mustermann raises Mustermann::CompileError rather than Mustermann::ParseError when a pattern contains malformed capture names such as empty captures or leading digits, while unclosed groupings raise Mustermann::ParseError and expand with :ignore still raises Mustermann::ExpandError when required keys are missing.
• assert Mustermann.new('/foo/:') and Mustermann.new('/foo/:123') raise Mustermann::CompileError instead of Mustermann::ParseError
• assert Mustermann.new('/foo/(bar') and Mustermann.new('/foo/{bar') raise Mustermann::ParseError with unexpected token messages
• assert Mustermann.new('^/foo', type: :regexp) raises Mustermann::CompileError when anchor characters are present in regular expressions
• assert Mustermann.new('/foo', type: :unsupported_custom_type) raises ArgumentError rather than Mustermann::Error
• assert pattern.expand(:ignore, {}) raises Mustermann::ExpandError when required captures are missing because :ignore only applies to extra keys
• assert pattern.expand(:invalid_behavior, id: 1) raises ArgumentError rather than Mustermann::ExpandError
• assert Mustermann::CompileError, Mustermann::ParseError, and Mustermann::ExpandError all inherit from Mustermann::Error < StandardError
