cider.nrepl.middleware.test does not bind clojure.test/*report-counters*

[vemv]

Brief

I have the impression that test runners are expected to bind clojure.test/*report-counters* during test execution. It looks like it should be initialized to clojure.test/*initial-report-counters*.

cider.nrepl.middleware.test doesn't appear to have this logic.

Why this is a problem

• I found at least one instance where inc-report-counter is invoked:

  cider-nrepl/src/cider/nrepl/middleware/test.clj

  Line 212 in ac0625f

  (test/inc-report-counter :test)

  • problem being, without the binding that is a no-op: https://github.com/clojure/clojure/blob/57ac70c904e8250f0bd4e084272659aeeb8749c6/src/clj/clojure/test.clj#L314-L320
  • i.e. there's effectively dead code in cider-nrepl, which is surely undesirable
• Also, the lack of this binding in a popular middleware precludes authors from designing testing macros that inspect clojure.test/*report-counters*
  • e.g., one could author a deftest-like macro that ensured that *report-counters* was incremented after execution of that deftest.

Likely an oversight on our part. PR welcome!
