IoT testing challenges during testing a device or software.
First, it's important to understand the architecture of the iot system you're testing. This will give you a good idea of where potential points of failure could occur. Then, you'll need to create test cases that cover all aspects of the system's functionality. This includes everything from its ability to connect to the internet and other devices, to its user interface and any special features it may offer. Once you have your test cases ready, it's time to start running them.
