IoT apps extend test activities to more devices, test cases, and compliance requirements. Handling this extension while maintaining high quality can be done with planning, innovation, and careful execution. Here are three recommendations for expanding your test strategies to ensure high-quality IoT applications.

"Why do we test software?" seems like a silly question—most people would say, “So we know it works, duh." But there are many other reasons we test our products, as well as many possible benefits besides confirming that a system does what we intended it to do. Figuring out the purpose behind your tests is illuminating.

Web services—the applications that talk to other applications—are generally finished before the GUI, so you can test the business logic before you think about the actual interface. You can improve the quality of your application, find interesting bugs that don’t exist in the GUI, and give web services some love.
