Understanding the Difference between Verification and Validation in Software Testing

Verification and validation are essential aspects of software testing in the context of Software Quality Assurance (SQA). Let's explore the difference between these two concepts:

Verification:

Verification is the process of evaluating whether a software system meets the specified requirements and standards set during the development phase. It focuses on ensuring that the software is being developed correctly and that each stage of the development process adheres to the defined requirements. Verification activities include code reviews, walkthroughs, and inspections.

Validation:

Validation, on the other hand, is the process of evaluating whether the software meets the customer's requirements and is fit for its intended purpose. It involves testing the software to ensure that it delivers the desired functionality, performance, and user experience. Validation activities include functional testing, user acceptance testing, and system testing.

Key Differences:

• Verification checks whether the software is being developed according to the requirements, while validation checks whether the software meets the customer's needs.
• Verification is focused on the development process, while validation is focused on the end product.

By understanding and implementing both verification and validation processes in software testing, SQA professionals can ensure that the software meets both the specified requirements and the customer's expectations.
