This is my take. I have one test suite that should be able to run upon file-save and be completed in about 5 seconds. Then another suite that takes about 20 minutes that I can run in CI or locally. I suppose unit vs integration, but I don't worry about conforming to those definitions too strongly. Basically tests in the first suite should be fast and able to run in parallel. If they touch the file system or talk to a local db that's fine as long as it's fast and safe in parallel. The second suite can do whatever.
