Testers today need to look more like developers than users. Automation is becoming essential, so understanding at least basic programming is a must. As companies adopt agile and deliver more frequently, modern testers should learn to code, understand continuous integration, and use tools to eliminate constraints.

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.
