Pytest simplifies testing with automatic test discovery, useful failure reports, parameterization, and a powerful fixture system.
Pytest eliminates boilerplate by using standard Python `assert` statements and provides detailed failure reports through assertion rewriting.
Use decorators like `@pytest.mark.skipif` to conditionally run tests and custom markers to tag and select specific test groups.
The `@pytest.mark.parametrize` decorator allows running a single test function with multiple sets of input data, reducing code duplication.
Fixtures use dependency injection to provide reusable setup and teardown logic for tests, allowing for modular and composable test resources.
Pytest provides built-in fixtures like `tmppath` for creating temporary directories and `monkeypatch` for modifying state on a per-test basis.
Explore the pytest plugin ecosystem, including `pytest-cov` for coverage, `pytest-bdd` for behavior-driven development, and `hypothesis` for property-based testing.
Learn how to migrate existing test suites to pytest and get a preview of upcoming features in the pytest 7.0 release, such as type annotations.
