I am trying to follow the https://clojure.org/dev/developing_patches to submit a clojure patch. There are a couple of things I don't understand. (1) It says I need to create a local branch named 'fixbug42', but it doesn't say whether that naming convention is important. I suppose I need to change 42 to the number of my bug, ie. 2652 (a la https://clojure.atlassian.net/browse/CLJ-2653). and (2) the instructions do not indicate what I need to do to add a test case for the bug I'm fixing. presumably a test which will fail before my patch, and will pass after my patch. Is adding test case per bug fix not a thing?

the branch name does not matter

a regression test (the way you described) is usually a good idea
