Python Fixtures Library

The `fixtures` library (not to be confused with `pytest` fixtures) provides a Python contract for reusable state and support logic, primarily for unit testing. It includes helper and adaptation logic to simplify writing fixtures and offers glue code for `unittest`-compatible test cases. As of version 4.3.2, released in March 2026, the library is actively maintained and supports Python 3.10 and newer. It offers a set of pre-canned fixtures like `LogHandler`, `MockPatchObject`, and `MonkeyPatch` for common testing scenarios.
