Andrew Gray updated the documentation for the thomhurst/TUnit repository, focusing on clarifying configuration guidance related to Visual Studio version support and the server mode flag. He analyzed version compatibility and commit history to ensure the README accurately reflected differences between Visual Studio 2022 17.13+ and earlier releases, specifically noting when the 'Use testing platform server mode' option is required or absent. Using Markdown and documentation best practices, Andrew’s work aimed to reduce onboarding friction and prevent misconfiguration by aligning user guidance with actual product behavior. The update improved traceability and addressed common support queries, though no code bugs were fixed.
