With sensors embedded everywhere, the world is becoming far more connected than ever before. From smartwatches and thermostats, to security systems, home appliances, and other evolving connected devices, the IoT world is moving past computers, tablets, and smartphones to just about every device you can imagine. The demand for connected devices is rising in unthought-of numbers, transforming the way we see, hear, and feel the world.
As IoT is set to revolutionize the world of business and drive revenue, it becomes imperative that the quality of these devices is given utmost importance to ensure optimum performance, security, and reliability. As users become increasingly accustomed to connected devices and IoT, they’ll expect new technology and apps to work flawlessly from the start. Companies that focus on quality will ultimately have the upper hand in ensuring user satisfaction.
Testing in IoT
In the development of applications which involve IoT, performance and behavior of the IoT service is crucial. Poor design may hamper the working of the application and may have an adverse effect on the end-user experience. As sensors increasingly connect hardware with applications, old testing methodologies must be reexamined. IoT services need to undergo robust testing methods to ensure performance meets the desired user requirements and the required SLA.
By adopting effective best practices, you can successfully execute IoT testing. Well-defined requirements, comprehensive test plans, and effective communication form the basis of IoT testing in addition to impeccable programming tactics and practices. Additionally, a sound understanding of the architecture, OS, hardware, applications, and protocols is essential to design good test cases. IoT testing encompasses seamless communication of the IoT device with sensors, applications, the cloud, and other networks. To ensure devices and apps stand up to real-world situations and maintain a high level of quality, you need to carry out a range of testing services that span the entire IoT lifecycle:
Functional Testing: Attractive IoT devices work all the time, everywhere, and for everyone. With IoT devices all around, you need to make sure the devices work in the hands of your users just as well as they do in your testing lab. Verifying the core functionality of your products across a full range of devices, locations, and environments is the ideal way to start. Check the error handling capability of devices in the network and carry out basic device testing; you need to verify that only gadgets with proper authentication are able to connect to the network and that the gadget disconnects from the network as soon as it is turned off. You also need to verify that the IoT app works seamlessly with different network connections and syncs with combinations of backend protocols.
Component Testing: The presence of an enormous number of devices within the IoT space makes it crucial to conduct end-to-end component testing. Checking devices for their hardware strength and durability is an essential first step. Next, test the devices for their embedded software and the applications that they use. Confirm if all the devices involved in the IoT testing can successfully register to the network, interact with other devices in the network, and exchange data. Ensure devices can connect to the network without a glitch and also check for compatibility of IoT devices with third-party software.
Performance Testing: Performance is a determining factor for user satisfaction and success of the IoT device. To check the overall responsiveness, throughput, and reliability, optimize the code to improve the performance, and validate the response time based on different user loads. Ensure that the IoT device performs uniformly under all conditions and confirm that there are no bottlenecks. See how the device behaves when there are multiple requests while checking for performance consistency. Use the result to improve speed, scalability, and stability of the device by carrying out appropriate tuning.
Security Testing: While the current IoT era goes on to prove beyond doubt that smart devices are being used to perform all kind of activities, on the flip side, this also means that a large portion of all our personal data and information is shared in a manner which, if not safeguarded, will lead to adversities. Therefore, privacy, reliability, availability, and authorization are factors that need to be considered with utmost precision. Ensure high levels of data encryption and agree on user roles and responsibilities. Verify that apps follow the required network security standards and validation mechanism and ensure effective authentication of the IoT device and the corresponding app.
While IoT is sweeping the world in every sense of the word, testing of IoT devices is met with many different challenges. Replicating the environment required for IoT testing is not only expensive, but also requires a lot of effort. Since the subsystems, sub-components, and services within the IoT realm are owned and managed by various groups and third-party units, inaccessibility to a single component could affect the testing of the entire system. In order to obtain the right test data among different systems, substantial planning and organization among multiple teams is required. It is also important to ensure that the devices that need to undergo testing are of adequate capacity and are available at the right place, at the right time. Overcoming issues related to compatibility, accuracy, complexity, and connectivity using appropriate testing mechanisms is imperative to ensure optimum quality of IoT devices.
