Testing is often seen as a destructive activity. Spotting and reporting failures may be regarded as criticism against the product and against the author. I, as a software tester, am the bearer of the bad news. We are the messengers of undesired revelations about issues.

Testing is important. It considerably contributes to assuring that the application does everything that it was designed for. Looking for defects requires curiosity, attention to detail and professional pessimism. You probably want to know as soon as possible that something is wrong with your product. Defects found during testing will save time and money later. Win-win!
