What is Verification and Validation in Software Testing?
In layman’s words, if you are giving a program of addition of two numbers to the customer… Verification is whether your s/w is adding two numbers properly. Validation is whether customer really asked for ‘Addition’ program. Verification is very obvious. Validation may sound weird but sometimes the customer’s requirement is misunderstood. So, the s/w will be giving the correct result but customer is not interested in that result in first place.
