Rather than running your entire test suite on every change, it builds a dependency graph and outputs only the tests impacted by modified files, dramatically reducing feedback time during development.\n\nThe tool works as both a standalone CLI (piped with git diff and pytest) and as a pytest plugin. It's designed for local development workflows in large codebases where full regression testing would be prohibitively slow. Snob does not predict test failures\u2014it selects tests based on static dependency analysis\u2014and is explicitly not intended to replace CI or full test suite runs, but to accelerate the inner development loop by often skipping 99% of irrelevant tests.","worth_installing":"Yes, if you work in a large Python codebase where full test suite runs are slow and you want faster local feedback during development. The tool is actively maintained, has no runtime dependencies, and carries permissive licensing. The caveat: wheel availability only for Python 3.10+ may limit adoption on older projects despite the >=3.8 requirement claim, and static analysis cannot catch dynamic imports or runtime side-effects, so it should complement rather than replace CI regression testing."},"id":"snob-lib","links":{"html":"https://skillfed.io/packages/snob-lib","md":"https://skillfed.io/packages/snob-lib.md","pypi":"https://pypi.org/project/snob-lib/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-01-11","license_spdx":null,"license_treatment":"permissive","name":"snob-lib","python_support":"supports_current","summary":"A tool that only selects meaningful python tests to run."},"popularity":{"monthly_downloads":94273,"position":13335,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.1.0"}
