Prepare workers

[CharlesPerrotMinotHCHB]

Hi,

Is there a way to have the workers prepared in the background?
I'm think about something like

# Prepares the workers in the background, do not block
pytest -n auto prepare

(...)

# Runs the tests
pytest tests

Are you looking for something like https://pytest-xdist.rtfd.io/en/latest/subprocess.html?
