100% testing is a worthy aspiration and we should all strive towards it in the same way that an Olympic athlete strives to beat world records. Just don't get too disheartened that we won't see a 3 minute mile.
For something like an operating system or a large scale RDBMS 100% testing is more like a 3 second mile than a 3 minute one.
