Using a mix-and-match approach, Software Test Attacks to Break Mobile and Embedded Devices presents an attack basis for testing mobile and embedded systems. Designed for testers working in the ever-expanding world of "smart" devices driven by software, the book focuses on attack-based testing that can be used by individuals and teams. The numerous test attacks show you when a software product does not work (i.e., has bugs) and provide you with information about the software product under test.
The book guides you step by step starting with the basics. It explains patterns and techniques ranging from simple mind mapping to sophisticated test labs. For traditional testers moving into the mobile and embedded area, the book bridges the gap between IT and mobile/embedded system testing. It illustrates how to apply both traditional and new approaches. For those working with mobile/embedded systems without an extensive background in testing, the book brings together testing ideas, techniques, and solutions that are immediately applicable to testing smart and mobile devices.
"Using the framework of attacks popularized by James Whittaker’s books, Jon Duncan Hagar describes those that are relevant here and extends the approach with new attacks specifically for mobile and embedded systems. He provides detailed information and guidance on how to test more effectively and efficiently in the mobile and embedded world. … Jon shows you what to test and how to test, giving ideas that you can use to do better testing of mobile devices now and save yourself serious trouble later on.
Jon’s extensive experience (much of it in the embedded world), his thorough research, and his deep knowledge give this book a solid foundation and provide helpful guidance and steps to take in applying testing attacks to mobile and embedded devices."
—From the Foreword by Dorothy Graham, Software Testing Consultant
"Every tester who wants to keep current needs to read this book, and you can read with confidence knowing you are being guided by the best in this business. … Learn by doing, with this book as your guide."
—From the Foreword by Lisa Crispin, Agile Testing Coach and Practitioner
