The Internet of Things (IoT) has emerged as a dominant segment to empower technology at the global level. Over the years, IoT has successfully captured both virtual and digital platforms. You will be surprised to know that close to 6.4 billion devices were linked to the Internet of Things (IoT) in 2016; the count is expected to surpass 20 billion by 2026!
Globally, inventors and innovators are determined towards the creation of smart gadgets for improving the lives of humans. But it is the testing professionals who are responsible for keeping a check on the safe functionality of different smart tools. For ensuring IoT devices do not face any performance, functionality or security issues, the testing experts need to act is a smart and tactical manner.
It might sound cliché that testing all things listed under IoT is essential, but even then there are several organizations that ignore and sideline the imperativeness of this act. Similar to this problem, there are several other challenges to IoT testing that need to be highlighted.
Let us try to focus on the top five challenges to IoT testing that should be addressed and resolved by testing professionals.
Diversification of IoT Devices and Platforms
The presence of different variations of hardware and software concerned with IoT devices makes it slightly difficult to streamline the testing process. This can be described with the inclusion of diverse versions of firmware and operating systems, which makes it unreasonable to test every possible hardware and software combinations.
As a possible solution, you can accumulate data from the client source to acquire the list of devices and software versions they use. Once you are aware of their device preference as well as the operating systems to test, make the most of this information for testing certain basic combinations guided in the correct direction.
Investigating Various Protocols of IoT Communications
Presently, IoT devices are known to implement a diverse set of protocols associated with communications. For instance, protocols like Extensible Messaging, Message Queuing Telemetry Transport (MQTT), Constrained Application Protocol (CoAP) and Presence Protocol (XMPP) are considered common, and each of them has their advantages and disadvantages.
An API is usually layered over transport protocol to make it less difficult for developers when it comes to forming a connection using the device. At the time of test automation, the testing professional can make use of the APIs and protocols along with the test plan. However, the testing tool needs to hold the capability to assist these protocols and APIs without any significant inconvenience.
Modern Security Risks with IoT Devices
As per bizarre statistical data, more than 70% of IoT devices are at risk against problems associated with security. It is the task assigned to the testers who must ensure better guidelines for a gadget’s password policy, together with the authorization aspect also given careful consideration.
Overloading Network Channels & Quick Data Concerns
It is crucial to remember that associated IoT gadgets heavily rely on quick communication. Hence, the network status is bound to impact the performance of a chosen IoT device. It is the task of experts to ensure certain pointers related to IoT testing of gadgets, which include:
- Exceptional devices do face issues as a result of network infrastructure; for example, unstable network hardware, congested WiFi channels, and inconsistent web connections. Therefore, the IoT devices and applications should be tested keeping in mind these peculiar conditions.
- Creating a network using the greater part of the varied conditions can be considered reasonable for once. As per observations, developers and testers frequently indulge in network virtualization to systematically replicate distinctive network settings. Investigation of CPU and memory simultaneously with IoT testing should be involved during the analysis of device system metrics.
Vast Presence of IoT Applications to Pose Major Challenge
One of the serious IoT testing challenges is linked to the presence of greater IoT devices and applications. With a purpose to authorize their performance and functionalities, there is a need to talk about well-structured test capabilities.
- It all comes down to the testers, who should possess an effective test strategy and ensure that the gadgets together with the software are constantly approved with the correct version.
- Furthermore, if the framework is dependent on the services laid down by the intermediary, there are chances that the tests might fall short as the intermediary service revamp. With the implementation of automated IoT testing, any shortcomings can be rapidly highlighted.
The correct and safe operation of any IoT device or gadget does require such IoT testing challenges to be resolved at the earliest.
