Validation vs Verification in Software Testing

Validation and verification are two vital aspects of software testing that serve distinct purposes:

Verification

Verification is the process of evaluating whether a system or component meets the specified requirements and standards. It involves checking that the software is being built correctly and that it adheres to the design and development specifications.

Validation

Validation, on the other hand, is the process of evaluating whether the software meets the customer's expectations and needs. It involves checking that the right product is being built and that it fulfills its intended purpose in the real world.

In essence, verification focuses on ensuring that the software is 'built right,' while validation focuses on ensuring that the software is 'built to the right purpose.'

Both verification and validation are essential steps in the software testing process to ensure the delivery of a high-quality product that meets the user's requirements.
