# Verification and Validation

### Verification And Validation:

In software testing, verification and validation are the processes to check whether a software system meets the specifications and that it fulfills its intended purpose or not. Verification and validation is also known as V & V. It may also be referred to as software quality control. It is normally the responsibility of software testers as part of the Software Development Life Cycle.

### VERIFICATION: (Static Testing)

Verification is the process, to ensure that whether we are building the product right i.e., to verify the requirements which we have and to verify whether we are developing the product accordingly or not.

Activities involved here are Inspections, Reviews, Walkthroughs

Check below video to see “Verification And Validation”

In simple words, Verification is verifying the documents

#### As per IEEE-STD-610:

The process of evaluation software to determine whether the products of a given development phase satisfy the conditions imposed at the beginning of that phase.

Am I building a product right? It’s a Low-Level Activity. Verification is a static method of checking documents and files.

### VALIDATION: (Dynamic Testing)

Validation is the process, whether we are building the right product i.e., to validate the product which we have developed is right or not.

Activities involved in this is Testing the software application

In simple words, Validation is to validate the actual and expected output of the software

#### As per IEEE-STD-610:

The process of evaluating software during or at the end of the development process to determine whether it satisfies specified requirements \[IEEE-STD-610]

Am I building a right product? It’s a High Level Activity. Validation is a dynamic process of testing the real product.

This is a brief explanation of Verification And Validation in Software Testing.
