If you are new to testing, you may wonder about the differences between QA, SDET, and Test Architect. These roles sound similar but each has its own focus. In this blog, we will explain them in simple English and show how they connect in a testing career path.
QA Role Explained
QA (Quality Assurance) professionals focus mainly on manual testing. Their responsibilities include:
-
Writing and executing manual test cases.
-
Reporting bugs and checking fixes.
-
Working with developers and product owners.
-
Making sure the product meets requirements before release.
In a QA vs SDET comparison, QA is often considered the starting role that is less technical but critical for quality.
