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.

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 test that reveals a bug has succeeded, not failed.

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.

Ivy! It's a natural disaster! You have to be there!

Persecution comes from people who are prejudiced.

O Shepherd. You said you would make my feet like hinds' feet and set me upon High Places". "Well", he answered "the only way to develop hinds' feet is to go by the paths which the hinds use.

God created a path to his kingdom that is simple and straight. The obstacles that stand between you and God were created by man.

still hope leads men to venture; and no one ever yet put himself in peril without the inward conviction that he would succeed in his design.

Bill Stevenson of The Descendants is really good, too.
