It works with dataclasses, Pydantic models, typed-dicts, msgspec structs, and other typed structures, making it straightforward to create test fixtures that match your schema.\n\nYou define a factory class that inherits from the appropriate factory type for your model, and then call `.build()` to generate a populated instance. The library uses faker under the hood to produce realistic values (names, addresses, dates, etc.) that respect the types declared in your model. This eliminates boilerplate fixture code and keeps your test data generation in sync with your schema as it evolves.","worth_installing":"Yes. Polyfactory is actively maintained, has no known vulnerabilities, low install friction, and solves a real testing problem\u2014eliminating manual fixture boilerplate. It's well-suited for any project using typed Python models that needs realistic mock data for tests."},"id":"polyfactory","links":{"html":"https://skillfed.io/packages/polyfactory","md":"https://skillfed.io/packages/polyfactory.md","pypi":"https://pypi.org/project/polyfactory/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-02-22","license_spdx":null,"license_treatment":"permissive","name":"polyfactory","python_support":"supports_current","summary":"Mock data generation factories"},"popularity":{"monthly_downloads":11299823,"position":1401,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"3.3.0"}
