Some authors are good at presenting theories but unable to connect them to practice. Other are good at telling stories from the trenches, but without being able to produce an analysis of the situation and propose some solutions. On the less examined domain of agile testing, Lisa Crispin and Janet Gregory are, luckily for us, presenting a book that covers both the personal experience of being a tester in agile projects and a conceptual vision of the place of quality assurance in software projects. Thus you will find in this book “stories” that comes from past projects and “mind maps” that helps to have a high-level vision of the material of each chapter.
The book Agile Testing by Lisa Crispin and Janet Gregory offers resources to organize the quality assurance and software testing activities in an agile project. It explains also the relationship between test automation and agility. It provides also a part dedicated to the chronicle of the agile testing activities during project life, showing how every member of the team could contribute to quality.
I think however that the more interesting contribution of the book is Testing Quadrants. This concept classifies testing activities depending on their focus (technology or business) and their intent (supporting the team or validating the product). Adding an agile perspective to the original work of Brian Marick, the authors provide resources and examples for each quadrant to make sure that you will cover all the aspects of testing for your project.
This book is certainly a very valuable resource for every people involved in software testing, even if this is not in an agile project. It will also be valuable for ScrumMasters and project managers that have to think on how to integrate the testing activities in their projects.
