Programmers & Testers, two roles divided by a common skill-set.

When we switch people from programming to testing and vice versa may reduce the quality of our software. I’ll get some quick objections out of the way: But, A person can be a great tester and programmer.  - Yes I agree. But, Programmers do a lot of good testing. - Yes I agree. None of the above are in conflict with my conjecture. Programming or writing software automates things that would be expensive or hard to do otherwise. Our software might also be faster or less error prone at doing whatever it replaces. It may achieve or enable something that couldn't be done before the software was employed. Writing software involves overcoming and working around constraints to achieve improvement. That is, looking for ways to bypass limitations imposed by external factors or limitations in the tools we use. For example, coping with a high latency internet connection, legacy code or poor quality inputs. A programmer might say they were taking advantage of the technologies’

In a previous post I discussed one method I use to improve my testing skills, spending spare minutes testing a machine or website that is readily at hand. The example I used was Google's search, in particular its currency conversion feature. This is useful for getting practice, and trying to speed up my testing, that is - finding information more quickly. Another activity I perform is watching someone else test something. As testers, we are often asked to be a second pair of eyes, as its assumed that a programmer might not notice some issues in their own code. The idea being that you will not be blinded by the same assumptions, and will hopefully find new issues with the software. Using the same logic, by watching someone else test, I can examine their successes and failures more easily. I've asked many people to test a variety of objects, usually things to hand, like a wristwatch or something I've recently bought. One recurring pattern I have noticed is how programmer
