Testing the Internet of Things (IoT) – An Exploratory Workshop


IotTST - Version:1
Description
There is an increasing amount of publicity, information and hype around the subject of the Internet of Things (IoT) and the Internet of Everything (IoE). What on earth are people talking about? Should I be interested? Will it affect me? What does it mean to me as a tester? In this workshop, Paul will explore the scope, range, architecture, complexity and challenges of testing an IoT system. Standards are emerging, and many commercial applications are bleeding edge, speculative or exploratory. Security and privacy dominates all of the concerns being articulated by industry commentators, but for non-trivial systems, significant functional and integration complexity challenges must also be overcome. There are also broader societal risks that the IoE brings and government, companies and individuals should pay attention to them. The architecture of the IoE is beginning to reveal itself and this exploratory session presents a seven-layer architectural model that will help you to make sense of it all and expose some of the technical risks we need to focus on as testers. Most of the concepts are explored through exercises and problem-solving. Some recommendations for formulating a test strategy for the Internet of Everything are presented.
