...be proved correct, they can only be tested thoroughly. As Dijkstra has commented (Dijkstra, 1970): "program testing can be used to show the presence of bugs but never to show their absence". In the jargon of the programmer, the errors show up at run-time rather than compile time. Similar considerations... | |

...determining if a program is correct or not is "program testing" at run-time. But, as Dijkstra said, "Program testing can be used to show the presence of bugs, but never to show their absence!".
