Lots. But the same is true for UT.
The supplement to my initial question (which, for new readers, or those
who have a limited attention span was "what do you know when your sysem
passes your tests that you didn't know before - other that that it
passes these tests, run in this order, today?") is:
"What do you do when your system *fails* a UT?".
Too often, the answer I have received is "find the error and correct the
code". Ten demerit points for anyone who thinks that is sufficient.
