QA is about making sure the software meets quality standards. It’s not just about finding bugs, but also about preventing them by improving processes. In super simple words: QA in software testing is a set of activities to make sure the software is built in the right way, works as expected, and keeps improving.
QA vs Testing
QA = Process-oriented (focus on how software is built).
Testing = Product-oriented (focus on what is built).
Example:
QA ensures the development team follows good coding practices, reviews, and standards.
Testing checks if the "Login" button actually works.
