because without further explanation it sounded like

• wanting tests that never fail
• or having test heuristics intelligent enough to make you unemployed.

at least now I'm sure what your up to.

Regarding your update, you can't avoid false positive tests.

But like I said you can reduce the likelyhood of them drastically for a reasonable prize by bundling many random test vectors.

Some my produce false positives, but hardly all of them.

In our case (2,0) may be OK but (666,42) would not.
