Group testing

The idea -as well as a draft- for this blog posting are around for quite a while now, what finally forced me to finish and publish it, was a talk with Lasse Koskela (@lassekoskela) at the Agile Testing Days 2011, where I told him about the approach of „group testing“ sessions within our team, and he insisted that I had to write about it. So thanks Lasse, for forcing me to finish and finally posting this article.
