IoT Testing Challenges

IoT Testing Challenges

The challenges an IoT tester are explained below:

Hardware-Software Mesh

IoT is an architecture, which is closely coupled among various hardware and software components. It is not only the software applications that makes the system but also the hardware ones, sensors, communication gateways etc. too play a vital role.

Only functionality testing does not help in completely certifying the system. There is always a dependency on each other in terms of the environment, data transfer etc. So, it becomes a tedious job as compared to testing a generic system [only software/hardware component].

Device Interaction module

As this is an architecture between different set(s) of hardware and software, it becomes mandatory that they talk to each other in real time/near real time. When they both integrate with each other, things such as security, backward compatibility, upgrade issues becomes a challenge for the testing team.

Real-time data testing

As we have discussed earlier that a Pilot testing/regulatory testing is mandatory for a system such as this, it also becomes very tough to get such data.

Being in testing team, getting regulatory checkpoints or getting the system deployed in the pilot is very tough. The step becomes even tougher if the system is related to Healthcare as per our example. So, that stays as a big challenge for the testing team.

User Iterface

The IoT is spread across devices belonging to every platform [iOS, Android, Windows, Linux]. Now, testing that out on devices can be done but testing it on all possible devices is almost impossible.

We cannot omit the possibility of the UI being accessed from a device which we don’t possess or simulate. That’s a challenge which is tough to overcome.

Network availability

Network connection plays a vital role as IoT is all about the data being communicated in faster speeds all the time. IoT architecture has to be tested in all kinds of network connectivity/speeds.

To test this, virtual network simulators are mostly used to vary the network load, connectivity, stability etc. But, real time data/network is always a new scenario and testing team doesn’t know where the bottleneck would develop in the long run.
