Questions tagged [pytest-mock]

pytest-mock provides the functionality of unittest.mock.patch as a pytest fixture. It allows for more convenient patching (avoids nested context managers or unused arguments). It provides the same API as unitest.mock.patch and unitest.mock.patch.object, and additionally provides patcher.spy, which allows spying on function without changing them.
