Can you make that easier to parse?
Should every test have a reference number (perhaps derived from its
filename?) that is not going to change and appears on the output line?
Should each test belong to a defined category, e.g. 'lvcreate' above.
What role do the *s serve?  Would a wider range of characters make
the output more readable?
Can the version of the test also appear in the test logs along with
complete command output?  [I noticed a '>/dev/null' earlier that ought
to disappear:-) ]

'ok' with 'must fail' is misleading - try inverting the descriptions
e.g. 'rejects negative stripesizes'  (plural as I'd assume a range of
values are being tested each time)
