You are not suggesting harness will replace the need of programmer's review aren't you? The thing might go in the totally wrong direction and no harness will stop it. Surely unless you write harness for every specific task at hand but then why is it any better than writing or at least reviewing the code itself?

it is not, it just helps to not go in the wrong direction as much. even in my comment i mentioned reviewing the code multiple times. so i do agree reviewing is essential.
