Given the following example charm layout:

Run all tests for current charm
%(prog)s
Run one or more tests
%(prog)s 01-standard 03-different_database
output:
Each unit test will return an output in the form or either:
RESULT : SYM
or
RESULT : SYM (SYM)
Where SYM is a Symbol representing PASS: ✔, FAIL: ✘, SKIP: ↷, or TIMEOUT: ⌛
In the event a status is rewritten by either the --fail-on-skip flag or the
--on-timeout flag the original status will be displayed in () next to the
computed status.
