For example if we need to fill in some records into database before class tests executed. The python_files setting in the pytest.ini file above means pytest will recognize Django's tests.py file. Visualising Results A test function should normally Node IDs are of the form module.py::class::method or module.py::function.Node IDs control which tests are collected, so module.py::class will select all test methods on the class.
