Credit cards are taking over the usage of notes and coins. This has benefits, but it is not possible to toss a coin with credit cards. Bob van de Burgt coined (!) the term flipability at EuroSTAR 2010 Michael Bolton tutorial, coin exercise. It is a lovely word, and can be used more generally to […]
In many cases, it is worthwhile to take a look at how your competitors do similar things. Among competitors I include products you’re trying to beat, in-house solutions (e.g. handmade Excel sheets) and analogue solutions, solving the problem without computer products. Charisma is difficult to test, but competitor comparison is one way to go. You […]
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 […]
I do not see myself as a member of any of the Schools of Testing, and I have ethical problems with labelling other people than yourself. However, I see the schools as a fruitful tool for enhancing your understanding of views on testing. So please join me in the following thought experiment. The following is […]
Now and then you hear that developers should implement better support for testability, so testers can work more efficient. This is all well, but what about the opposite; how can testers make developers go faster? System testers have system (and a lot of other) knowledge, and we can see if the product turned out really […]
I have entered EuroSTAR’s VideoSTAR competition for 2011, main reason might be that I want more people to see the excellent introduction movie Mårten and Henrik made for me a couple of years ago. My title is “Set All Testers Free!”, and I can’t say I have the details set for a talk, but it […]
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 […]
There are some discussions about current certification schemes, but there is not so much attacks and defense of the actual content. This is from ISTQB Glossary 2.1: black box test design technique: Procedure to derive and/or select test cases based on an analysis of the specification, either functional or non-functional, of a component or system […]
We all test as children; we are curious and want to find things out, before we are one year old we want to break things, and after three we ask “What If” questions. My first ambitious testing journey came many years later. Still a naive teenager, I started studying Philosophy at the university. It was […]
