This lets you test code that depends on heavy or unavailable libraries (like OpenCV, Django, or NumPy) without installing them, which is useful when testing a library that uses those dependencies but you want to isolate your test environment.\n\nThe plugin works via a `stub` fixture in individual tests or a global `stub_global()` function in conftest.py. You pass a dictionary mapping import paths to stub types: `'[func]'` generates a function, `'[cls]'` generates a class, `'[mock]'` generates a MagicMock, and `'[mock_persist]'` generates a persistent mock. You can also provide custom objects directly. The stubs are applied before test execution so imports succeed without the actual dependency present.","worth_installing":"Yes, if you need to test code with external dependencies you don't want to install\u2014the plugin is simple and has no runtime dependencies. However, maintenance is abandoned (last release 2020-04-28), so compatibility with Python versions beyond 3.8 is unverified and you should test it in your environment first. For active projects, consider whether a maintained alternative or manual mocking would be more reliable long-term."},"id":"pytest-stub","links":{"html":"https://skillfed.io/packages/pytest-stub","md":"https://skillfed.io/packages/pytest-stub.md","pypi":"https://pypi.org/project/pytest-stub/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2020-04-28","license_spdx":null,"license_treatment":"permissive","name":"pytest-stub","python_support":"unspecified","summary":"Stub packages, modules and attributes."},"popularity":{"monthly_downloads":94774,"position":13307,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.1.0"}
