5 Key Points for Optimizing Your IoT Testing Strategy

Every day, the Internet of Things (IoT) is getting smarter thanks to the convergence of the digital and physical worlds. But IoT is also becoming more complex by integrating different systems such as sensors, mobile applications, web interfaces, etc. That is why it is necessary to adopt an IoT testing strategy that takes into account these multiple access points to ensure an optimal customer experience.

1. Test the usability of your IoT solution for a successful experience

Every interaction between a user and an IoT solution is, in essence, unique and unpredictable. The ways in which your customers use your solution are often surprising and difficult to anticipate. For this reason, real-life tests performed on real devices and in various contexts are the only way to ensure the functionality and usability of your solution. To do this, it is necessary to understand how users view the IoT, its uses, and even its dedicated application or software. It will then be possible to verify that the IoT will behave according to the established scenario tests.

2. Secure connectivity and interoperability at the heart of your IoT strategy

Interoperability describes the ability of a system to interact with another via a connection such as Bluetooth, Wi-Fi, 5G, LTE-M, etc. Ensuring the interoperability of your IoT solution is vital, especially when an IoT device goes offline temporarily.

The implementation of functional testing will ensure that no data is lost or modified. It will also verify that the exchange that takes place between the data does not corrupt the desired behavior and that the applications are able to execute it independently.

3. Don’t compromise when it comes to security!

Currently, the security of IoT devices and connected objects is a major concern for customers and users. More than ever, it is necessary to take this criteria seriously. When integrating it in your functional testing phase, make sure that all data is perfectly protected and encrypted while being exchanged or transferred. It will also ensure that the user interface is properly secured with a robust and truly effective password system.

4. Integrate performance testing into your strategy

Gain peace of mind by ensuring that your IoT solution is stable, fast, capable, and responsive, even when subjected to specific workloads. By testing the stability of your platform and the scalability of your system, you guarantee its robustness and reliability under a variety of circumstances, irrespective to the number of users or devices connected and regardless of the volume of data exchanged.

5. Ensure foolproof compatibility

Finally, the last key point is the evaluation of your solution's compatibility with a large number of devices and different operating system (OS) versions. Because your customers do not all use the latest version of their OS and there are multiple browsers and smartphone and tablet models, the testing phase can be tedious. Implementing IoT functional tests can help you to ensure the compatibility of your solution under any circumstance.
