It would be cool, if one could define a set of possible verdicts.
You have "Successful", "Untested", and "Failed",
which is OK for many purposes. But if you do tests
according to one of the many standards, you might have
different needs. E.g. ISO-9646 has five verdicts:
None = no result yet, untested
Pass = good, successful
Inconc = inconclusive, unclear
Fail = bad, failed
Error = there was an error in performing the test
If you test according to POSIX 1003.3 you have the verdicts:
PASS = good, successful
FAIL = bad, failed
UNRESOLVED = inconclusive, unclear
UNTESTED = no result yet, untested
Some testing frameworks add XFAIL (= expected fail), UPASS
(= unexpected pass) and UNSUPPORTED (= the implementation
under test doesn't support a feature) to the POSIX verdicts.
