What does "onSave": "test-only" do?

I've seen this option in the README, but I don't see it anywhere in the code. I thought that its intended purpose was to watch for a test file to be saved and then run only the tests that appeared to be modified, but I'm making edits to a test file that are completely pointless and purposely situated outside of any actual test in the file, and then Jest runs all the tests in the file.

if you turned off the watch mode and configured onSave then it should trigger jest run when you save a file jest considered as test file, i.e. it should be within the list returned by jest --iistTests. if it's not doing that, then you could create an issue with a sample repo so we can dig deeper

OK...and what is the difference between that and "onSave": "test-file"?
