The request is generic ('test-tagging'), so the best-matching products are test frameworks that support test markers/categories. pytest supports marking and selecting tests via its framework 2, Playwright offers a full-featured test runner with tracing and parallelism 9, and Microsoft's test-tagging action classifies existing tests by standard traits and reports their distribution 1. The request does not name a language or platform, so the choice depends on the test stack.
A question back: Which language or test framework does your project use (for example Python/pytest, JavaScript/Playwright, or C#)?
