Developing custom software or hardware for IoT and embedded systems is challenging. It's crucial to understand the scope of the undertaking and all its potential bumps. IoT QA testing presents three major challenges.
Complexity is the biggest challenge of IoT testing. A connected IoT infrastructure sends and receives uncountable signals every day. There are several reasons why an error could send the system off track:
Innumerable platforms. IoT systems have many hardware and software components that work together. Hardware and software elements must work flawlessly together for the infrastructure to function. Any interaction between software and hardware can lead to errors due to the peculiarities of the environment, during data transfer, or at any other stage.
Excessive communication protocols. Many communication protocols are used for IoT networks to communicate with one another and their controllers. Real-time or near-real-time communication is required. Hardware and software integration can pose compatibility, security, scalability, and upgrade issues.
Too much attack surface. Businesses become more vulnerable as they grow. Furthermore, it is nearly impossible to run all the necessary penetration tests manually, making IoT automation testing even more important.
No test frameworks
Every IoT ecosystem is different. Regardless of how complex or simple your enterprise IoT is, you need a test automation framework. In IoT development, there is no out-of-the-box framework that meets all of its unique requirements. An expert will be able to develop a test framework tailored to your ecosystem's specific needs.
System complexity contributes to the problem. A system's layers - device, gateway, cloud, data - must also be tested separately and in relation to one another.
Hard to automate and integrate into CI/CD
IoT QA also faces the challenge of automating the testing process and integrating it into CI/CD. Testing IoT automation must be an integral part of the development process. In most companies, testing cannot be automated and integrated with CI/CD, causing unnecessary overhead.
