What Is QA (Quality Assurance) and Software Testing?

It is not enough for a product to "work"; it must work under the right conditions, with the right result, in a consistent way. QA (Quality Assurance) is the process discipline that provides this guarantee. Testing is the most visible tool of QA.

Common Test Types

• Unit Test: Verification at the function/component level
• Integration Test: Are the modules working correctly together?
• Regression Test: Did the new change break what was already working?
• UAT (User Acceptance): Do the business scenarios pass from the perspective of real users?

Why Is QA Not Just "Finding Bugs"?

QA sets a quality standard: requirement clarity, acceptance criteria, test automation, performance and security checks, release risk analysis… Good QA shifts the cost from "fixing it later" to "preventing it from the start".
