Research direction

Locate the reverse-string exercise's existing test file and review how skipped tests and BATS_RUN_SKIPPED are handled. Add the proposed echo -n case only if the exercise's maintainers approve the difficulty change, then run the exercise tests and verify that n- produces -n successfully.

Written by the indexing model from the issue text.

Description

Given that the builtin echo command cannot output the string "-n" (ref Why is printf better than echo?), we could amp up the difficulty of reverse-string by adding another diabolical test:

@test "echo -n" {
  [[ $BATS_RUN_SKIPPED == "true" ]] || skip
  run bash reverse_string.sh 'n-'

  assert_success
  assert_output -- '-n'
}

This will force the student to learn about a fairly nasty echo edge case.

On the other hand, reverse-string is currently an easy exercise with difficulty 1, and adding this test is likely to break a large proportion of existing solutions.
