Want to be a testing guru? Use reachability graphs (Part 6)

Continuing with our exploration of reachability graphs, the graph below shows another very interesting bug in Chrome’s PDF viewer. The beauty of reachability graphs is that it is remarkably easy to follow the abstract states to recreate bugs, and it is impossible to make mistakes in doing so. Go ahead and follow the abstract states […]

Want to be a testing guru? Use reachability graphs (Part 2) 1

A fairly long time ago, I introduced reachability graphs and showed you how to start using them to debug applications. After all, debugging is a form of testing. In this post, I’ll continue exploring reachability graphs for the purposes of exploratory testing. To illustrate their useful power, I will use reachability graphs to test some aspects of an […]

Reachability graphs make irrelevant states clear

Want to be a testing guru? Use reachability graphs

Reachability graphs help you structure your testing in a way that makes it faster, more focused and helps you avoid dead-ends. Via certain testing patterns that reachability graphs can make visible, it can also help you break through hard-to-test applications and problems. It can even help you debug! Wanna know more?
