pytest-cache

pytest-cache was an external plugin for pytest that provided mechanisms for caching data across test runs, including options to re-run only last failed tests (`--lf`) or run failed tests first (`--ff`), and a `config.cache` object for plugins to store and retrieve values. Its core functionality was integrated into pytest itself starting around versions 2.8 and 3.8. The last release of the standalone `pytest-cache` plugin was version 1.0 in June 2013, making it effectively abandoned as its features are now part of `pytest` core.
