Usability
The absolute majority of IoT devices are designed to be interacted with in some way by real human beings, which is why usability testing is a must. With this type of testing, the IoT QA team will make sure that the device and the application it’s connected to create a positive user experience regardless of the user’s level of technical proficiency.
Smoke
Smoke testing is one of the IoT testing types that are present in nearly every software product released to the public. Smoke testing is one of the first steps in the QA process and helps the team make sure that the current build is stable enough and ready to be tested further. Skipping this step, or insufficient smoke testing, can lead to disrupting the whole testing process and to a significant portion of the testing budget going to waste.
Performance
When it comes to IoT device testing, it’s important to remember that many of them operate under unusual conditions and handle large amounts of data. This makes Performance testing one of the types of IoT testing that can be successfully automated, provided that the IoT QA testing team has the necessary expertise and possesses the proper selection of tools.
Compatibility
Some IoT solutions are designed to work on just one platform, while others are intended for use on a myriad of devices, platforms, and operating systems. This is why compatibility testing is important for all IoT projects but absolutely crucial for many of them. For this type of IoT testing, it’s very important to run the tests on as many devices as possible, and this is one of the instances where TestFort’s collection of over 250 physical devices proves particularly helpful.
Integration
Due to the fact that a typical IoT solution consists of multiple modules, it’s important to test these modules not just independently, but also as part of the integration process. In other words, the QA team will look at how successfully the new additions to the existing setup — whether it’s a new piece of software or a new hardware module — are integrated into the system.
Scalability
One of the ultimate goals of an IoT product is to increase the number of customers and ensure presence in as many territories as possible. This is why it’s essential to include scalability in the IoT testing process. It will help the stakeholders avoid any unpredictable performance issues the solution can face as the customer base starts growing.
Connectivity
The connection between the different layers of the IoT solution is what actually allows it to be called an Internet of Things solution. Without a stable connection, an IoT device is just a piece of plastic that cannot do much. This stage of IoT device testing should involve checking the mobile and wireless connectivity, as well as any related types of connectivity that are specific to the product.
Security
By some estimates, around 70% of all IoT devices globally are currently vulnerable to security attacks. And with the majority of IoT solutions dealing with sensitive data in one way or another, whether it’s the smart home technology or a healthcare device, security is not something to be taken lightly.
Localization
With some exceptions made for IoT products designed for a limited local market, IoT devices are typically marketed and sold all over the world. Therefore, English being the only available interface language won’t cut it. Localization testing not only tests the correctness of the translation, but also makes sure the product complies with local standards and requirements.
Regulatory
IoT products are a unique type of software and hardware that has unique characteristics and often deals with the most sensitive aspects of human existence. From home security and smart cities to medical devices — the IoT market is intensely regulated. This makes regulatory testing one of the key IoT testing types for any solution.
