If you find what differentiate the good tests from the bad tests, it would
be good to create a wiki page explaining what to be careful about to make a

One thing that have bitten my ass in the past is the JIT being smart and
removing some "dead" test code because it has no side effect. I am sure
there are plenty of mistake like this to be avoided.
