The Difference Between Verification and Validation in Software Testing

In software testing, verification and validation are two critical processes that ensure the quality of a software product. While both are essential steps in the testing process, they serve distinct purposes.

Verification

Verification is the process of evaluating whether a software system meets the specified requirements and standards. It involves activities such as code reviews, walkthroughs, and inspections to check that the software is developed correctly according to the design specifications.

Validation

Validation, on the other hand, focuses on evaluating whether the software meets the user's needs and expectations. It involves testing the software against the user's requirements and involves activities such as functional testing, usability testing, and performance testing.

Key Differences

The key difference between verification and validation lies in their objectives - verification ensures that the software is built correctly, while validation ensures that the right software is built.

Importance in Software Quality Assurance

Both verification and validation are crucial in ensuring software quality and reducing the likelihood of defects. By conducting thorough verification and validation activities, software testers can detect and rectify issues early in the development process, leading to a more reliable and user-friendly software product.
