  Making the leap from a Quality Assurance (QA) role to a Software Development Engineer in Test (SDET) can open up exciting new career opportunities. It involves transitioning from a primarily manual testing role to one that blends software development and automated testing. Here’s a concise guide to help you make this transition effective.   Understanding the Differences Firstly, it’s crucial to understand the differences between a QA and an SDET role. QA professionals focus on ensuring the quality of the software through manual testing, writing test cases, and identifying defects. In contrast, SDETs are skilled in both development and testing, creating automated tests, developing testing frameworks, and sometimes even writing code for product features. The role of an SDET requires a solid understanding of software engineering principles, programming, and automation tools.   Building a Strong Foundation in Programming One of the most significant steps in this ...
