TUnit

Trigger On

• the repo uses TUnit
• you need to add, run, debug, or repair TUnit tests
• the repo uses Microsoft.Testing.Platform-based test execution
• the repo uses ClassDataSource<...>(Shared = SharedType.PerTestSession), ParallelLimiter, TUnit.Playwright, or --treenode-filter

Value

• produce a concrete project delta: code, docs, config, tests, CI, or review artifact
• reduce ambiguity through explicit planning, verification, and final validation skills
• leave reusable project context so future tasks are faster and safer

Do Not Use For

• xUnit projects
• MSTest projects
