The only benefit I see is to don't write GOOD cases. So the workflow would be
like:
1) Write only "bad" cases in test file
2) First run corrects that they are all become "good"
3) Second run checks that none of "good" are not flagged as FP.
So since we write all good cases explicitly (I hope so) then we don't need
double-run.
