The Testing challenges ahead for the Internet of Things


The proliferation of the Internet of Things (IoT) and its related technologies and software applications has confronted the testing teams with a number of challenges. With IoT, where most of the everyday objects communicate with each other, and where technologies upgrade every other day, new challenges have emerged for the software testing industry.

For any given software project, QA teams need to ensure that a single app functions as designed and performs as per  the user expectations. As the IoT devices  seamlessly connect and communicate with a wide variety of platforms, devices and operating systems, the additional stress on the testing team is enormous. However, such challenges are completely outweighed when it comes to the security challenges posed by the software architecture of the IoT application. With innumerable devices connected to each other in the IoT, there are numerous potential attack vectors that can be exploited by the cyber criminals. If cyber criminals were to tamper with the settings of such devices, the consequences could be highly devastating.

With the amount of detail that needs to be covered in an IoT testing, having a list of critical QA priorities is very important. Such priorities need to cover the length and breadth of the challenges of IoT testing.

The different areas of testing an IoT application are as follows:

Functionality: Web/UI, embedded and back-end computing.

Compatibility: Multiple Configuration, Protocol and product Versions, Backward Compatibility and Mobile OS.

Connectivity: Communication between the devices, third party applications and the infrastructure.

Performance of the network, communication and internal computation.

Exploratory: Rare scenarios and beyond functional requirements and structured testing.

Security: Privacy, Autonomy and Control.
