pytest

Purpose: pytest is a framework for writing small, readable tests that can scale to complex functional testing for applications and libraries.
Assertions: pytest provides detailed information about failing assert statements through assertion introspection.
Test discovery: pytest automatically discovers test modules and functions using standard naming conventions.
Fixtures: Fixtures provide resources to tests, including unique temporary directories, and can be shared or parametrized.
Compatibility: pytest can run unittest test suites, including trial, out of the box.
Plugins: pytest has a plugin architecture and the project home reports more than 1300 external plugins.
Supported runtimes: The project home lists Python 3.10+ or PyPy 3; the version support page says pytest 9.0+ requires Python 3.10+.
Install: The getting-started guide installs pytest with the command pip install -U pytest.
Test selection: The command line can select tests by module, directory, keyword, collection path, or marker expression.
Integrations: The documentation describes loading external plugins, including pytest-cov, and pytest can be invoked from Python code.
Support: The project directs users to GitHub issues for bugs and feature requests and offers commercial support and maintenance through Tidelift Subscription.
Security: The project asks users to report suspected security vulnerabilities through a new GitHub security advisory instead of creating an issue.
Enterprise services: The Tidelift subscription description lists security updates, licensing verification and indemnification, maintenance, version guidance, roadmap input, and tooling and cloud integration.
Intended users: pytest is described for testing applications and libraries, and its enterprise support offer is aimed at organizations using open source dependencies to build applications.
