The tests and the program being tested serve as checks
on each other. If they don't match, something is wrong
somewhere, and it's up to you to decide whether it's
the program or the test that's wrong.

It's possible that there could be errors in both
which cancel out, but if the tests are reasonably
thorough, it's pretty unlikely.

Having the tests written by someone different from
the program should make it even less likely.
