Testpy

Testpy is an open-source testing framework for Python designed to simplify writing and running tests. It emphasizes a minimal API, fast feedback, and extensibility through plugins.

Key features include automatic test discovery, assertion helpers, fixtures for setup and teardown, parameterized tests, a plugin system, and parallel test execution. The framework also prioritizes readable failure reports and deterministic test behavior where feasible.

At its core, Testpy comprises a test collection stage, a test runner, and a reporting subsystem. Tests are defined as functions or methods that follow a conventional naming pattern, and fixtures provide reusable setup code that tests can request. Assertions use standard Python syntax, enhanced with helpful error messages to improve debugging.

Testpy provides a command-line interface to run tests, collect tests, and manage configuration. Typical usage involves placing tests in files following common naming patterns such as test_*.py, then invoking the testpy command to discover and execute them. Results include detailed tracebacks, a summary of failures and skips, and options for extended reports.

The project is community-driven, with documentation and examples available on its official repository. It aims to be interoperable with existing Python tooling and to offer a clean pathway for extensions via plugins or integrations with other testing ecosystems.
