"""
Conftest Fixtures

pytest looks for conftest.py modules throughout the directory structure. Each
conftest.py provides configuration for the file tree pytest finds it in. You can
use any fixtures that are defined in a particular conftest.py throughout the file’s
parent directory and in any subdirectories. This is a great place to put your most
widely used fixtures.
