It has been said by many, but I heard it from Fiona Charles: “don’t ever fall in love with your model”, and this is a warning I want to elaborate. A model is a powerful way to understand how the system works, and thereby also how it can fail. But a model can also narrow […]
First of all. I am honored to be invited as a guest writer at the testeye! I will start my contribution by asking for your assistance. In the next year I have been asked to give a couple of classes for test managers that are fairly new in their role. I have been looking through […]
Typecasting is the process by which a film, TV, or stage actor is strongly identified with a specific character, one or more particular roles, or characters with the same traits or ethnic grouping. For many actors this has been a nightmare, even if they have earned a fortune on it. I believe that some of […]
Testers are often in a unique position because we know a lot about the system as a whole, but also a lot about the details of the operating software. There are interesting dynamics between the small and the large, and with a human mind in between, a lot of important information will emerge. “The distinction […]
Today we celebrate our 100th post on this blog! It has been an interesting journey for us so far; and we realize that we have only begun this ride, a ride with no destination but to enrich ourselves with wisdom and knowledge through discussions and by sharing thoughts. And you, our readers, are a very […]
If you haven’t read the excellent articles by Michael Bolton regarding Testing vs. Checking yet, now is a good time to do it: http://www.developsense.com/blog/2009/08/testing-vs-checking/ http://www.developsense.com/blog/2009/09/transpection-and-three-elements-of/ http://www.developsense.com/blog/2009/09/pass-vs-fail-vs-is-there-problem-here/ Done? One thing that struck me with this is that the more testing you do will result in less testing and more checking. I.e., the more you test, the more […]
Session based testing is most often discussed in combination with exploratory testing. The idea is to make exploratory testing more structured by using it, as James Bach expresses it. I like the whole concept about testing in sessions, thus breaking the day into chunks of work. Considering that you know that there is an infinite set of […]
Now and then I read that testers don’t know enough about Usability, that there is a need for a Performance Testing expert, that a Security consultant should be called in, or that a master of the used technology would make Installation and Compatibility testing possible. This might be true in the general case, but there […]
Let me begin by saying that these are my beliefs ever since I took the ISEB/ISTQB certification. But when I thought of this recently, I think I need to make a statement and try to help all those that are rejected because they are not certified. ————————————– In the search for a qualifying certification many […]
I use Jerry Weinberg’s definition of quality: “Quality is value to some person”; and I use Cem Kaner’s extension to the definition so that it becomes “Quality is value to some person (that matters)”… I.e. quality is inherently subjective. And there are a lot of persons that are affected by software that we produce… With this in […]
