@FynnBe - could you share / let me know what local testing you're using for workflows? Are you using the local actions runner that we discussed a short while ago still or more just doing local testing of the python scripts called by the workflows?

Great to see the work here! Thank you both!

I now only test with pytest locally and try to have the pytests map all processes.
Also I try to keep the workflows very light, e.g. call only one script.
And then testing online (test.yaml) workflow isn't so painful when pytests pass locally
