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

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

A design remedy that prevents bugs is always preferable to a test method that discovers them.

A good threat is worth a thousand tests.

More than the act of testing, the act of designing tests is one of the best bug preventers known.

Second law: The complexity barrier. Software complexity (and therefore that of bugs) grows to the limits of our ability to manage that complexity.

First law: The pesticide paradox. Every method you use to prevent or find bugs leaves a residue of subtler bugs against which those methods are ineffective.

One of the saddest sights to me has always been a human at a keyboard doing something by hand that could be automated. It's sad but hilarious.

If you can't test it, don't build it. If you don't test it, rip it out.

Software never was perfect and won't get perfect. But is that a license to create garbage? The missing ingredient is our reluctance to quantify quality.

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

One of the great beauties of politics as an art form was its lack of restriction to merely standard forms of realism.

It is not really a small thing when in small things we resist self.

Nature is in earnest when she makes a woman.

If you're going to have to beg them to play, it's not going to work.

As actors, we're all encouraged to feel that each job is the last job. They plant some little electrode in your head at an early stage and you think, 'Be grateful, be grateful, be grateful.'

Hitler built a fortress around Europe, but he forgot to put a roof on it.

The focus of education should not be on suppressive information but on kindling the thirst for knowing.

The thoughts we choose to think are the tools we use to paint the canvas of our lives.

Negative thinking is always expensive--dragging us down mentally, emotionally, and physically--hence I refer to any indulgence in it as a luxury.

If you're heading downtown from Centeral Park, my advice is to take the subway. Flying pigs are faster but way more dangerous
