Programming Quote by Robert C. Martin

“Testing may convincingly demonstrate the presence of bugs, but can never demonstrate their absence."- Edsger W. Dijkstra, Computing Pioneer (1930–2002), "Programming as a discipline…

If the objective of testing were to prove that a program is free of bugs, then not only would testing be practically impossible, but…

Testing proves a programmer’s failure. Debugging is the programmer’s vindication.

— Boris Beizer

Program testing can be used to show the presence of bugs, but never to show their absence!

— Edsger Dijkstra

Testing shows the presence, not the absence of bugs.

— Edsger Dijkstra

The real value of tests is not that they detect bugs in the code but that they detect inadequacies in the methods, concentration, and…

A test that reveals a bug has succeeded, not failed.

“Testing gathers information about a product; it does not fix things it finds that are wrong.”

— Gerald M. Weinberg

“Software is like a science. We show correctness by failing to prove incorrectness, despite our best efforts.”

— Robert C Martin

A good test case is a test case that has a high probability of detecting an undiscovered error, not a test case that show…

I'm not saying we purposely introduced bugs or anything, but this is kind of a natural result of any complexities of software... that you…

— Will Wright

“The problem that Dijkstra recognized, early on, was that programming is hard, and that programmers don’t do it very well.”
