Things connected to the internet are the Internet of Things, and many things are connected to the internet nowadays. Real estate agents are now selling smart homes that have amenities controlled via the internet; health enthusiasts are monitoring their health with devices that can be controlled by their smartphones. In a nutshell, we are surrounded by things that are operated by the internet.
As the demand for smart devices is increasing, the need for the accuracy of these devices is also at its peak. Now the question here is how we can judge whether the device is functioning accurately or not.
The answer to that question is via IoT testing. But before we proceed, let’s understand why accuracy is so important for IoT devices.
To answer this question, I want to give you an anecdote. Suppose you are using a Fitbit that is connected to your smartphone. Now, the Fitbit is recording all your health-related data and syncing it with your smartphone app. Imagine if that data is somehow wrongly filed!!!
It would be preposterous, right?
It is not just for a Fitbit, it is for all IoT devices. They are voraciously used in almost every industry, including logistics, supply chain, hospital management, school management, OEMs, and many more.
All these industries need accurate data, and if the IoT device is faulty, then that will be a blunder which is very difficult to mitigate. Now, let’s go on with the IoT testing.
What Is IoT Testing?
In simple words, the testing of the IoT device is checking whether the device is functioning correctly or not (Isn’t that obvious!!!). It is same as testing of web apps and other legacy software.
In the real world application, IoT has three core elements or components, i.e. Things, Computing, and Communication. In a testing process, a script is made which analyzes all these elements. As an IoT tester, you have to scrutinize and verify all the functions that make the application reliable for communicating across the entire network. Read in detail about >>What is IoT ?
Types Of IoT Testing Approaches You Must Know
1. Performance Testing: Hardware-Software
In performance testing, the hardware-software components of the IoT device are validated by implementing several test cases. The main motive of performance testing is to recognize the way the device interacts with the software. For ensuring the real-time credibility and effectiveness, a tester must validate the compatibility of the software with the sensors of the devices. Without this, you cannot guarantee whether your software is fetching the accurate information from the sensors or not.
2. Multiple Domain Inspired Compatibility Testing
It is very crucial to know how your IoT device interacts with each other and with the digital network (aka multiple platforms spread throughout multiple domains). With compatibility testing, you will get an estimate of how the interaction mentioned above goes. This testing approach is simple. A tester carries out multiple validation considerations, which includes encryptions check-ups, compatibility with the hardware, and other security standards.
3. UX Testing
As the name suggests, this approach includes how the application system is functioning. With the help of multiple user test cases, you can validate the back-end and front-end functionalities, which also includes user experience.
4. Security Testing
Security testing is very crucial when it comes to IoT testing. This includes analysis and testing of system fidelity, privacy, and information security. After the security testing, you will be ensured for the consistent performance of your IoT device in the real-time ecosystem. It also helps you in identifying possible security vulnerabilities that a hacker can leverage to hack into your system.
Challenges You Might Face While Testing IoT Devices
Here we will discuss potential challenges that you can face while performing testing of your IoT devices. Let’s get started,
1. There Is A Complicated Mesh Of Hardware-Software Network
When you observe the architecture of the IoT devices, you will find that it is coupled among numerous hardware and software components. This tells us that when you perform functionality testing, you might face a tedious testing process that has the potential not only to annoy you but also hamper the timeline of the deliverables.
2. The Availability Of Network
In an IoT ecosystem, the network connection plays an important role as consistent data communication at high speed is crucial. You need to test your IoT devices in every possible type of network connectivity and speed. The catch here is no matter how much you test your devices; real-time network always caters to you a different scenario for which you cannot be specific for your devices.
3. Module For Device Communication
As mentioned above, the entire IoT device ecosystem involves too many combinations of hardware and software sets. This makes it crucial for them to interact with each other effectively on a real-time basis. This makes the testing process challenging as there are so many factors to consider, such as upgrade issues, backward compatibility, and security.
In The End
In a nutshell, the approach of IoT testing may vary depending on the ecosystem or architecture of the system involved. We, at BugRaptors, welcome you to discuss your testing needs so that our certified testers can provide you the viable solution that will ease your IoT development lifecycle.
