Which statement describes a testing activity that checks that design outputs meet inputs?

• A. Validation checks that the product fulfills user needs.
• B. Regression testing checks for unintended side effects.
• C. Unit testing verifies individual components.
• D. Verification checks that design outputs meet inputs.

Answer: (D)

Verification is the process of confirming that the design outputs actually conform to the inputs or specifications. It answers the question “are we building the product right?” by checking that what is produced matches what was required in the design inputs. In this context, a testing activity that compares design outputs to the design inputs ensures the artifacts, models, or configurations align with the original requirements, making verification the best fit.

Validation, on the other hand, asks whether the final product fulfills user needs and is the right solution for the intended use. Regression testing looks for unintended side effects after changes, and unit testing focuses on verifying that individual components work correctly in isolation.
