It provides fixtures that either start a PostgreSQL instance on demand (session-scoped) or connect to an existing one, and manage test database creation, isolation, and cleanup. The plugin uses psycopg 3 to handle connections and database operations, returning a connected psycopg.Connection object to your test functions.\n\nThe plugin supports pre-populating test databases via SQL files or Python functions, with a template-cloning strategy that speeds up test runs by building a template database once per session and cloning it for each test. You can customize fixtures through factory functions, configure connection parameters via command-line options or pytest.ini, and chain multiple fixtures to layer data pre-population. It handles both managed PostgreSQL processes and connections to external instances (e.g., Docker containers).","worth_installing":"Yes. The plugin is actively maintained, has no known vulnerabilities, and solves a common testing problem with low install friction. Use it if you need to test code that interacts with PostgreSQL and want automated database lifecycle management. The copyleft license does not restrict your application code, only derivative works of the plugin itself."},"id":"pytest-postgresql","links":{"html":"https://skillfed.io/packages/pytest-postgresql","md":"https://skillfed.io/packages/pytest-postgresql.md","pypi":"https://pypi.org/project/pytest-postgresql/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-15","license_spdx":null,"license_treatment":"copyleft","name":"pytest-postgresql","python_support":"supports_current","summary":"Postgresql fixtures and fixture factories for Pytest."},"popularity":{"monthly_downloads":6639491,"position":1876,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"8.1.0"}
