What is a software developer in test (SDET)?

A Software Developer In Test (SDET) is a professional who combines software development and testing skills to ensure the quality of applications. SDETs design, develop, and maintain automated test frameworks and tools, and often write code to test software products just as developers write code to create them. They collaborate closely with developers and quality assurance teams to identify issues early in the development process, improving product reliability and efficiency. SDETs are integral in enabling continuous integration and delivery by automating repetitive testing tasks, allowing companies to release software faster and with higher quality.
