Physicists – Testers in Disguise?

My background is in science. I have spent 11 years (a third of my life, believe it or not) studying mathematics, statistics and most importantly – physics, experimental astroparticle physics to be specific.

I have been trained

  • to be sceptical
  • to question
  • to think analytically
  • to think logically
  • to be curious
  • to try to understand how things work rather than accepting stated facts
  • to explore

All of these things I think make very good qualities for a tester too.

My research consisted of searching for a signal in a data set made up mainly of background noise. Feel free to read my thesis. In order to do my research I had to write my own software. Since the results of using my software to process the data were going into my thesis I had to test that the software was behaving as I expected it to in an attempt (futile maybe) to minimize the risk of making a complete fool of myself.

I claim that testing in a wider meaning of the word comes naturally to experimental physicists, even when talking about software testing. The life of any experimental physicist consists of

  • data acquisition
  • data analysis, more often than not using some homemade software
  • publishing results from data analysis

Publishing (preferably interesting) results is the basis of your career, if you do not publish you do not exist. Imagine what would happen (and does happen) if you publish results you later have to retract because your software is found to have severe defects. Physicists are aware of what is at stake – and unlike what is generally the case in the software industry, every mistake is going to hurt the physicist personally.

Hence physicists – and all other scientists with integrity – test their software tools meticulously to make sure they understand how they work and that  they work as expected. It is not a strict, structured testing that ISTQB would approve of, but the physicists have their hearts in the right place. They want things to work and be reliable, and is that not really just what we all want?

Christin Wiedemann (@c_wiedemann) is the Co-CEO and Chief Scientist of PQA Testing. After finishing her PhD in Physics at Stockholm University, Christin Wiedemann started working as a software developer for the Swedish consulting company HiQ. Christin soon discovered that software testing was more interesting and challenging than development and subsequently joined the Swedish test company AddQ Consulting. At AddQ, she worked as a tester, test lead and trainer, giving courses on agile testing, test design and exploratory testing throughout Europe. Christin developed a course on exploratory testing, and is a co-creator of the exploratory testing approach xBTM. Christin currently lives in Vancouver, where she joined Professional Quality Assurance (PQA) Ltd. in 2011. In her current role as Chief Scientist, she drives PQA’s research and method development work. She continues to use her scientific background and pedagogic abilities to develop her own skills and those of others. LinkedIn Profile
