Question

What is the difference between "verification" and "validation" in software testing?

a.

Verification determines if the software satisfies specified requirements while validation determines if the system has been built right

b.

Verification determines if the system has been built right while validation determines if the software satisfies specified requirements

c.

Verification and validation are the same thing

d.

There is no difference between verification and validation

Posted under Software Engineering

Answer: (b).Verification determines if the system has been built right while validation determines if the software satisfies specified requirements Explanation:Verification evaluates a system or component to determine if the products of a given development phase satisfy the conditions imposed at the start of that phase, trying to answer the question "Have we built the system right?" Validation, on the other hand, evaluates a system or component during or at the end of the development process to determine if it satisfies specified requirements, trying to answer the question "Have we built the right system?"
