The `pytest-xdist`_ plugin extends pytest with new test execution modes, the most used being distributing
tests across multiple CPUs to speed up test execution::

    pytest -n auto

With this call, pytest will spawn a number of workers processes equal to the number of available CPUs, and distribute
the tests randomly across them.
