You decorate a test function with @pytest.mark.datafiles() and list the files or directories you want copied, then receive a pathlib.Path object pointing to the temporary copy. This keeps your original test data untouched across test runs and ensures each test works on its own isolated copy.\n\nThe plugin is useful when tests need to read or modify files without side effects\u2014common scenarios include testing on large media files, image processing, or any workflow where you want to verify file handling without corrupting your test fixtures. It supports both string paths and pathlib.Path objects, offers options to control directory nesting and duplicate file handling, and integrates seamlessly into pytest's fixture and marker system.","worth_installing":"Yes. This is a stable, low-friction plugin (pure Python, only pytest dependency) with active maintenance and no known vulnerabilities. It solves a common testing problem\u2014data isolation\u2014cleanly and has been proven in production since 2015. Install it if your tests work with files and you want to avoid fixture pollution or manual cleanup."},"id":"pytest-datafiles","links":{"html":"https://skillfed.io/packages/pytest-datafiles","md":"https://skillfed.io/packages/pytest-datafiles.md","pypi":"https://pypi.org/project/pytest-datafiles/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-01-04","license_spdx":"MIT","license_treatment":"permissive","name":"pytest-datafiles","python_support":"supports_current","summary":"py.test plugin to create a 'tmp_path' containing predefined files/directories."},"popularity":{"monthly_downloads":123874,"position":11893,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"3.0.1"}
