In a broad perspective, the Internet of things (IoT) can be perceived as a vision with technological and societal implications. From the perspective of technical standardization, IoT can be viewed as a global infrastructure for the information society, enabling advanced services by interconnecting (physical and virtual) things based on, existing and evolving, interoperable information and communication technologies. Through the exploitation of identification, data capture, processing and communication capabilities, the IoT makes full use of things to offer services to all kinds of applications, whilst maintaining the required privacy. The concepts of u1-society, u-network, u-city and others have been formulated in support of the worldwide perspective for IoT applications, services and technologies which may be enabled by radio frequency identification (RFID), ubiquitous sensor network (USN), machine-oriented communication (MOC), machine-to-machine (M2M) communication, smart device communication (SDC), Cloud-enabled IoT services (CIS), where RFID has been taken into account by ISO/IEC JTC 1/SC 31, sensor network technologies by ISO/IEC JTC 1/WG 7, USN by ITU-T SG20, MOC by ITU-T SG13, M2M by ITU-T and ETSI, SDC by TIA, CIS by ETSI, OGC, and W3C.

NOTE 1 – "u" stands for "ubiquitous" which has been interpreted as a capability for any services at anytime and anywhere through any devices.

All these keywords have some similar use cases and imply some identical functions but consider some different technology views. The IoT may be seen as an umbrella for all these technology keywords.

Since the IoT has such broad concept and may be associated with various enabling technologies, interoperability issues shall be considered.

In general, IoT discovers various new types of connectivity which may be used in different customer-oriented applications (e.g. flying ubiquitous sensor networks (FUSN), IoT-based augmented reality (AR) and so on).

Also, taking into account the secure authentication mechanism used by IoT-based technologies and IoT identity, IoT may be considered as one of the tools to be used for combating counterfeiting.

Bearing in mind all the above, the testing of the IoT technologies/applications are becoming more important today, especially in terms of interoperability of the IoT devices and trust of the used IoT systems.

In addition to traditional IoT applications, it is advisable to consider testing in areas in which the largest implementation of IoT-devices is observed:

– Smart Sustainable Cities;

– Wearable devices;

– Industrial Internet of things (IIoT);

– Network-based driving assistance for autonomous vehicles;

– Flying networks based on Unmanned Aerial Vehicles.

As a rule, in each of these areas there are different scenarios for connecting IoT-devices to the Internet, cloud platforms and remote services. In this regard, the consideration of issues of testing procedures of IoT-devices seems to be very relevant.
