I used to be a bit skeptic towards the word “heuristic”. It seemed needlessly advanced, and things are possible to explain in other words. But when I read Gigerenzer’s Gut Feelings about how to catch a flying ball, it all came together. For software testing, which can’t be complete, is dependent on many factors, with […]
I have completed a trilogy on the theme The Eye of a Skilled Software Tester edition 1: Lightning Talk, Danish Alliance, EuroSTAR 2010 edition 2: Article, The Testing Planet, March 2011 – Issue 4 edition 3: Presentation, Scandinavian Developer Conference, april 2011 Some things have changed over time; in the first two I didn’t focus […]
The big drawback and big advantage with reliability testing is that it is easiest and most effective to perform together with other testing. A separate automated reliability regression test suite could cost an awful lot to implement, but reliability in your spine when performing any type of manual test, together with deviations, is cheap, interesting, […]
I spend a lot of time testing new features for the next release. I actively try to not test the features in isolation, to not use the easiest data and environment. One example of this is that I often use “documents” that are more complex than necessary, that includes elements and strange things that aren’t […]
Software testing is difficult because there are so many possibilities; not only all functions and their interactions and attributes, but also possbible users’ data, needs, environments and feelings. Good software testing need to deliberately sample, and understand what is important. This understanding that evolves over time give testers an intuition about which tests to run, […]
There are situations when you have to choose to run a test or not. Some organizations quantifies properties like time, risk and get a prioritized list. Most probably just use their intuition, but if that’s not enough, or you want to explain and share the reasoning, you can try using a fast and frugal tree […]
Many of you have played roleplaying games/storytelling games or at least heard of them. In those games you have a gamemaster/storyteller, who arranges scenes or scenarios that the players act in. He does not control what each player does nor how he/she should interact with others. Each player usually plays a role/character that has a […]
Analogies are powerful when they help us understand something (they shouldn’t be used to argue.) And virtually any analogy can be good, you don’t know until after you have tried. So this exercise is to use an analogy from your daily life, compare it to testing in general, or to your current area of concern. […]
When I read about the “classic” test design techniques, I don’t recognize the way I come up with test ideas. Sure, the implicit equivalence partitioning is used pretty often, and I get happy the few times a state model is appropriate, but the testing I perform seldom has the unit/component focus that these techniques have. […]
Monday Henrik started his journey by car from Karlstad and went down to Gothenburg to join with Martin. Both of us were going to take the train down to Copenhagen. Not surprisingly there were delays and the train was cancelled… Instead we headed back to Martin’s house and loaded Henrik’s car and took off. After […]
