The Most Important Lesson of My First Software.

With my first software, I underestimated testing.

At the time, I wrote a small piece of software for my father. I was immensely proud when the printer started up and printed the receipts I wanted. Quickly I went to him to present the result. Interested, he immediately tried it out himself and after 2 pressed keys the whole application crashed. I was devastated.

So, I learned how important it is when testing to approach the software with different eyes.

Take testing seriously. #

If you only look at your software through your developers’ lenses, you will miss a lot of things.
