To me the best answer to this is that L&A tests and even parallel
testing cannot reveal the presence of Trojan Horse software.
Tests--of any kind--can only test the advertised functionality of
software. There is no possibility of uncovering inserted software
that is designed to permit manipulation of the legitimate functions.
It's like trying to prove a negative--it can't be done.

Post election audits are conducted to ascertain whether any kind of
irregularity occurred in the election. This is a completely different
function than testing.
