what is validation and verification..

Answer / vimal

Verification: It is a process confirming that software
meets its specification document. It basically involves
walkthroughs, review and inspection. QA team members define
the process as per the specification.

Validation: It is a process confirming that software
meets its user requirements. It basically involves testing.
Validation technique done after verification process. QC
team like testers they r going to implementing the process
defined by QA team.

Verification is QA activity which ensures that the software
product is designed to deliver all the functionality
whatever mentioned in the requirement specification
document. Reviews, walkthroughs and inspections are its
techniques. It is a preventive phase.

Validation ensures that whatever mentioned in the
requirement specification document should be the intended
behavior of the software. Validation is actual testing. It
is a corrective phase and is QC activity.

Answer / nithya

Verification:

Verification is static testing.This testing involves
walkthroughs,reviews ,inspections.This is testing whether
design document is prepared according to the requirements
or whether there is any deviation from it.This is testing
whether the developer has coded according to the design doc
(requriement) or is there is any deviation dfrom it.This is
checking whether test cases are written according to the
design and requirement docs or is there is any deviation
from it.On the whole this is just verifying whether we are
building the Product right or are we deviating from what's
expected to be achieved.Here v dont perform any testing on
the application we just verify everything manually thatsy
it's called static Testing.

Validation:Validation is dynamic testing.Here we validate
the applcaition to confirm that the application works
satisfying the customer's needs.verification is checking
whether v are building the Product right satisfying
customer needs.in this teting v enter valid and invalid
inputs and observe how application behaves.To perform
validation for the applciation v implement techniques like
boundary value analysis,Erro guessing and Equivalence
partitioning.

verification and validation together is called V model.The
name V is given considering the time gap.Time gap b/t unit
testing and coding is less compared to the time time gap
b/w UAT and requirements gathering.Time increases

Answer / ramyasri

Hai...

Verification:
The process of evaluating software to determine
whether the products of a given development phase satisfy
the conditions imposed at the start of that phase.
Verification is the process of determining that a
computer model, simulation, or federation of models and
simulations implementations and their associated data
accurately represents the developer's conceptual
description and specifications


Validation:
The process of evaluating software during or at
the end of the development process to determine whether it
satisfies specified requirements. In other words,
validation ensures that the product actually meets the
user's needs, and that the specifications were correct in
the first place, while verification is ensuring that the
product has been built according to the requirements and
design specifications.
Validation ensures that ‘you built the right
thing’. Verification ensures that ‘you built it right’.
Validation confirms that the product, as provided, will
fulfil its intended use.
