When you use lru_cache in your application code and then mock or patch dependencies in tests, the cache can retain stale values from previous test runs, causing tests to fail or pass unexpectedly depending on execution order. This plugin solves that by busting the cache between tests, restoring proper test isolation.\n\nThe plugin works automatically once installed\u2014no code changes needed. By default it disables lru_cache everywhere, but you can configure an allowlist of specific module paths where caching should remain active, useful when other dependencies rely on cache behavior to function correctly within a single test run.","worth_installing":"Yes. This is a targeted fix for a real problem\u2014test pollution from lru_cache\u2014with low install friction, active maintenance, no vulnerabilities, and permissive licensing. If you use lru_cache in code under test and have experienced test ordering issues or mocking problems, this plugin eliminates the problem with zero code changes."},"id":"pytest-antilru","links":{"html":"https://skillfed.io/packages/pytest-antilru","md":"https://skillfed.io/packages/pytest-antilru.md","pypi":"https://pypi.org/project/pytest-antilru/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-03","license_spdx":"MIT","license_treatment":"permissive","name":"pytest-antilru","python_support":"supports_current","summary":"Bust functools.lru_cache when running pytest to avoid test pollution"},"popularity":{"monthly_downloads":239801,"position":8915,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.0.1"}
