An organisation that treats its programmers as morons will soon have programmers that are willing and able to act like morons only.

'How to test?' is a question that connot be answered in general. 'When to test?' however, does have a general answer: as early and as often as possible.

Anybody who comes to you and says he has a perfect language is either naive or a salesman.

A program that has not been tested does not work.
