Software Development Engineers in Testing (SDETs) are professionals who specialize in both software development and testing. They design, develop, and maintain automated test frameworks and tools to ensure the quality and functionality of software applications. SDETs work closely with developers to create robust test cases, identify bugs, and improve product reliability.
