Hi, UPDATE: Sorry for the non working link. I corrected the href!No, for as long as you know all the valid inputs to give to your program. Once you start giving invalid inputs (in the sense that you know you'll trigger the error) your program is incorrect. I once read Program Construction and Verification in which Dijkstra got paraphrased: program testing can be used very effectively to show the presence of bugs but never to show their absence. On this site you can read more.
