Can you explain the difference between verification and validation in the context of software testing?

Understanding Verification and Validation in Software Testing

For the Software Quality Assurance (SQA) category interview question, the difference between verification and validation is crucial in the context of software testing. Let's delve into these concepts:

Verification:

Verification is the process of evaluating whether a software system meets the specified requirements and standards. It aims to determine if the system is being developed correctly. It involves reviews, walkthroughs, and inspections to ensure that the software adheres to its intended design and development guidelines. Verification focuses on the software development process rather than the actual functionality or quality of the product.

Validation:

Validation, on the other hand, is the process of evaluating a developed software system to ensure that it meets the customer's expectations and needs. It involves testing the software to check if it fulfills the intended purpose and functions correctly. Validation confirms that the software meets the user requirements and is fit for its intended use. It focuses on the end product and its usability.

Therefore, while verification ensures that the software is being built right, validation ensures that the right software is being built for the end-users. Both verification and validation are essential components of software testing to guarantee the quality and reliability of the software product.
