Worked on the thomhurst/TUnit repository to enhance documentation supporting users migrating from xUnit, NUnit, and MSTest. Focused on clarifying the transition to new test filter semantics, the contribution introduced a migration callout within the test filters guidance, highlighting the change from --filter to --treenode-filter. A concise mapping table was added to illustrate common filter patterns, directly addressing potential onboarding challenges. The update was implemented exclusively in Markdown, leveraging technical writing and documentation skills to improve user understanding. This docs-only change minimized deployment risk while streamlining support and onboarding for new users adapting to TUnit’s updated command-line interface.
