In programming, it’s often the buts in the specification that kill you.

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.

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

This I want to believe implicitly: Man was born for love and revolution.

Sometimes coping with the difficulties success brings is much more difficult than coping with the difficulties failure brings!

You have to treat Hollywood like it's your boyfriend - he's there all the time.
