Definition
Python's most popular testing framework, supporting simple assertions, fixtures, parameterization, and plugin extensibility.
In Depth
pytest discovers and runs tests automatically, uses plain assert statements, provides powerful fixtures for test setup/teardown, supports test parameterization, and has a rich plugin ecosystem (pytest-django, pytest-cov, pytest-asyncio). It's simpler and more powerful than unittest.
Example Usage
Running 'pytest tests/ -v --tb=short' in CI to validate the Django backend's API endpoints, model logic, and management commands.
Business Context
Automated testing prevents regressions, enables confident refactoring, and catches bugs before they reach production. pytest makes writing tests fast and enjoyable.
