This is not the whole picture – far too often, quality work is not a pleasant experience.

Testing is awesome and the most fun and amazing part of any product development! Strangely enough, I have found that most people look at me weird when I exclaim something like this. I don’t know why… I’ve often been the first tester in a project. A very common first reaction from […]
