Allow a test to PASS, FAIL and WARN.
WARN should be emitted if a WARN level log (or else configured level) is present on the log.
The report would show bars that are green, red and yellow.

This needs adding a new possible state to test results.
This is anyhow a different criterium from current reporting which may be yellow if non-critical tests fail, because there tests can just PASS and FAIL, then are categorized afterwards.

Thanks a lot!
