Roleplaying your test scenarios Martin Jansson No Comments

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.

test design technique name competition Rikard Edgren 16 Comments

When I read about the “classic” test design techniques, I don’t recognize the way I come up with test ideas.

Exploratory Testing Best Practices* Rikard Edgren 9 Comments

When testing software, the very best inspiration and reality check comes from the software itself. It helps you test beyond requirements, and investigate what the software really is capable, and incapable, of. These are my best practices for exploratory testing. 1. understand what’s important – we can’t test everything, and we can’t find all bugs. […]
