A quick snip on testing

I have recently had two different offline topics end up with the same point so I figured I would pass it on here as well. Testing and why it is important to test to failure and not just test. To stick to the intuitive reason, it is because then you know when your system will break and what will happen when it does. It is naive to believe that your system will be 100% problem free, it is a far more realistic expectation to accept that you just don't know when.

One of the fundamental race conditions of the universe is that as soon as you build a better, more idiot-proof system, the world will build a better idiot. Similarly in a system which is successful and experiencing growth, you will eventually hit a point that exposes problems that didn't show themselves under lesser pressure or lesser load. In aircraft they X-Ray and image things like propellers not because they want to ensure that it is perfect, but so that they know what quality it is. Under the right conditions a very tiny bubble can cause a propeller to literally fly apart. Better to know these things up front.

My Jana RSS feed recently (inside joke) recently came across with these two links, one for example, one for humor that are relevant to this topic. Check out this Ultimate Failure test... and fly with a little better feeling in your heart because you know that they care enough to do this. Then check out Monkey Testing at it's best. (I am trying very hard to resist the 1000 monkeys and Shakespeare sonnet reference... darn... I failed.)

In conclusion remember, it's ALWAYS better that you know where things will blow up than for someone else to tell you.
