CI is annoyingly slow. Test splitting up for more speed. This bring a single PR up to 44 checks from 33. Looking at CI history this brings times down from 15 - 20 mins down to ~10 ish.
This introduces the use of
pytest-splitto divide up test workloads across CI machines (requires no communication so much better performance boost vs pytest-xdist or other)This also introduces the use of the
cache@v2action to store copies of the pip cache on a per OS/image basis. This can help cut down drastically on install time.
