Cast the thrown error to SpecParsingError instead of coercing it to CustomStringConvertible, which goes through NSError bridging and yields a different description on Linux. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

InvalidConfigsMappingFormatTestsfails on Linux CI now that the newer ubuntu runner image runs Swift Testing tests (example: https://github.com/yonaskolb/XcodeGen/actions/runs/38357691066).The error matcher coerced the thrown
any Errorwithas any CustomStringConvertible. That coercion goes throughNSErrorbridging, which on Darwin forwards to the Swift error'sdescriptionbut on Linux produces the genericNSErrordescription, so the comparison fails even though the correctSpecParsingErroris thrown.The matcher now casts to
SpecParsingErrorand compares itsdescription. This was the only Swift Testing test using the pattern.🤖 Generated with Claude Code
