This is what I do for a living and I think I’ve gotten quite good at it. This is my philosophy on testing that, I think, drives my success.
“You will always hear me defending the need for testing. Any product or service can be tested. Testing brings objectivity to assessing the quality of a product. I consider testing to bring eyes to a product. I imagine it like an inspector in a manufacturing shop looking at a piece through a magnifying glass. He knows every important measurement about that piece and if it passes or fails. There is often an attitude that testing is beneath people; that some products or skills are just so sophisticated they are not subject to objective metrics. This attitude is adopted, for instance, when assessing students with standardized tests. This is nothing more than arrogance and unwarranted ego. I face this very attitude over even technical products. We dont need a test for that it will surely work. This is the bane of my existence and I laugh at it! Every single time someone has said this, there has been a problem with the product. Every single time. Ive never made a test that didnt end up being valuable. I think people are opposed to testing as they dont want eyes on them for what those eyes will find. If you want a quality product, you must have testing. Period.”
