Explaining the Difference Between Verification and Validation in Software Testing

Verification and validation are important aspects of the software testing process that play crucial roles in ensuring the quality and correctness of the software being developed.

Verification:

Verification involves the process of evaluating the software to determine whether the product of a development phase satisfies the specified requirements. It focuses on ensuring that the software meets the established standards and requirements set forth during the development process. Verification answers the question, "Are we building the product right?"

Validation:

Validation, on the other hand, is the process of evaluating the software during or at the end of the development process to determine whether it meets the customer's expectations and requirements. It involves checking if the right product is being built. Validation answers the question, "Are we building the right product?"

Overall, verification ensures that the software is being built correctly according to the specifications and standards, while validation ensures that the software meets the customer's needs and expectations. Both verification and validation are essential components of the software testing process to deliver a high-quality product to the end-users.
