In the TAR process, which phase is dedicated to testing the product to reveal defects before delivery?

• A. Planning
• B. Development
• C. Testing
• D. Delivery

Answer: (C)

Testing is the phase where the product is tested to reveal defects before delivery. It focuses on validating that the product works as intended, meets requirements, and behaves reliably under expected conditions. By executing test cases and exploring edge cases, testers uncover defects that developers fix prior to release, reducing risk and ensuring quality. Planning defines what to build and how it should be assessed; development is where the product is actually built; delivery is the handover to users after testing shows the product is ready.
