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

Автор образца записал здесь то, чего ожидал бы разработчик или модель. Контракт ниже — это то, что действительно выполнялось.

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
