Problem with unitt v3: incorrect exit status

[glennj]

I noticed that line-up has the wrong unitt version in the test suite (I'll PR that momentarily).

However I noticed that the unitt executable does not emit a non-zero exit status:

$ ~/.arturo/packages/bin/unitt
Uncaught error in tests/test-line-up.art:

                  Hint: Perhaps you meant... unit? ?
                                       or... units ?
                                       or... _unittsection_ ?


        }
        code: 1
]

$ echo $?
0

We have a false positive pass for this exercise.

Is this configurable in unitt.toml, or is it a bug in unitt?
