Pytest issues when too many apps running

When running pytest --cov, the test returns many errors, but only when too many apps are running in the background. When I close all apps on my mac (except Google Chrome), the test runs fine.

Below is a copy of my chat with Victor, with more details

Adam Lawrence 1 hour ago I just realised I was running pytest earlier and not pytest --cov

Adam Lawrence 1 hour ago When I run pytest --cov I still get some errors

Adam Lawrence 1 hour ago Any ideas what this could be? Is it a related issue?

Victor Negîrneac 1 hour ago unfortunately not, it has to do with multiprocessing packages that we rely upon, it is fine to run pytest only for now

Victor Negîrneac 1 hour ago do you have a new mac with the Apple processor btw?

Adam Lawrence 1 hour ago No, quite an old mac (2012 model MacBook Pro)

Adam Lawrence 1 hour ago Incidentally, I had no problems running pytest --cov on quantify-scheduler, I only got the errors on core

Victor Negîrneac 1 hour ago can you try closing almost all the apps that you have opened, like fully cmd+q and running the tests again? I have been having some of this issues because the operating system is not quick enough to communicate between processes (when i have way too many things opened, specially heavy things like videos or videocalls) (edited)

Adam Lawrence 1 hour ago OK, I'll try that in a little while and get back to you

Victor Negîrneac 1 hour ago This might pinpoint the issue, tough I do not have a solutions yet

Victor Negîrneac 1 hour ago thanks

Adam Lawrence 1 hour ago Yes - it worked when I closed down everything except Google Chrome.

Adam Lawrence 1 hour ago I suppose this is good enough for the time being

Victor Negîrneac 1 hour ago could create an issue about it in quantify-core? you could put there our chat for future reference
