Datatype positioning heuristic – a bug story.


Once in a while you come across a bug that sticks to you. One of those bugs reoccurred to me during the Rapid Software Testing class (RST) given by James Bach. Among a lot of very useful lessons in testing James spoke about boundary testing. I learned that when a boundary is set often other boundaries are not far away. That lesson reminded me of a bug! James challenged me to name the technique I used that found the bug. So here’s the story on how a boundary test turned out to be an adventure, ultimately resulting in the discovery of the datatype positioning heuristic.


It’s finally the user’s turn

During the start of the fall I was in Potsdam (near Berlin) attending a new conference on mobile application development: Mobile App Europe. Smartphones are already among us for at least 7 years. So why start a new conference now? The short answer is: We are starting to understand the potential of mobile.
Even though humanity is using more and more mobile devices we have to realize that the mobile development field is still quite young. From a technical point of view the applications, devices and platforms have become more mature. iOS is already in the 8th major release. Google is almost halfway the alphabet with android releases. So all is going well there. So why do I call the industry still young?
I think understanding people themselves is still lacking behind. The way users interact with mobile devices is still not well understood by IT and Business. This impedes the full potential of these devices in my opinion. And this will even be more important for smart glasses, watches, thermostats and other smart things that will be connected to the internet. So what’s next in Mobile?

Spaceteam: Lessons in team dynamics and testing in 15 minutes

I’ve just returned from the wonderful Let’s Test conference in Sweden. The conference had many good talks, very wise and knowledgable people and lots of great discussions. Besides all that, games played a central role at the conference. For some reason testers, myself definitely included, like to play games. At several test conferences games are played and test puzzles are solved in test labs and workshops. I remember last years speakers dinner at the agile testing days turned into a massive riddle solving party. Let’s test however took it one step further. And I contributed with a new game: Spaceteam!
