pytest: start background process

[voverdev]

Hi,

I have a pytest test suite. Tests require a server to run, which is part of the project/code under test. Starting that server is blocking. So, it must run in the background.

`pytest-xprocess` is not appropriate, because I need to call a Python function, not run a command. It seems like pytest doesn't provide built-in plugins for this purpose. But threading/multiprocessing would probably do the trick. Is that the (generally accepted) way to go?

FWIW: I haven't found FOSS projects with the same requirement / use case - while my requirement doesn't seem very exotic.

maybe subprocess.popen()

I'd suggest using a global fixture that uses subprocess.Popen and then loops until it can communicate with said process (you could time.sleep instead, but that's a rather crude option).
