Validation vs Verification in Software Testing

Validation: Validation is the process of evaluating whether the software meets the end user's requirements and is fit for purpose. It involves checking if the right product has been built.

Verification: Verification, on the other hand, is the process of evaluating whether the software conforms to its specified requirements. It involves checking if the product has been built correctly.

It is important to understand the distinction between validation and verification in the software testing life cycle (STLC) because:

1. Validation ensures that the software meets the customer's requirements and is useful for its intended purpose.
2. Verification ensures that the software is implemented correctly according to the specifications.
3. By understanding this difference, testing teams can prioritize their testing efforts effectively and ensure comprehensive test coverage.
4. Proper validation and verification help in delivering high-quality software that meets the user's needs and expectations.
5. It aids in reducing rework and costly defects by catching issues early in the development process.
