Challenges of testing complex Internet of Things (IoT) devices and systems

![CDATA[The rise of Internet of Things (IoT) in past few decades is commendable. This significant growth clearly states the importance of security from internet threats. IoT systems involve numerous devices and ad-hoc embedded systems that require internet access and the amalgamation of various cloud technologies. IoT is a budding industry that provides variety of products, services and systems and therefore requires quality assurance. These systems are very complex in nature and are used in real world environments. For these reasons, IoT systems and devices are obliged to testing. It is a challenge to the testing community because of its issues, complexity and newness. The paper discusses the IoT systems and devices and the types of testing performed to them. It also highlights the challenges on testing these complex systems because of their issues and tells a few proposed solutions from literature to solve some part of these problems.]]
