Best 12 quotes of Boris Beizer on MyQuotes

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

A good threat is worth a thousand tests.

Bugs lurk in corners and congregate at boundaries.

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 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.

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

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

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

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.

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

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.

Anything written by people has bugs. Not testing something is equivalent to asserting that it's bug-free. Programmers can't think of everything especially of all the possible interactions between features and between different pieces of software. We try to break software because that's the only practical way we know of to be confident about the product's fitness for use.
