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.
Verification: Are you building it right? Ensure that the
software system meets all the functionality.Verification
takes place first and includes the checking for
documentation, code etc.Have static activities as it
includes the reviews, walkthroughs, and inspections to
verify that software is correct or not.Done by developers.
Validation: Are you building the right thing?Ensure that
functionalities meet the intended behavior.Validation occurs
after verification and mainly involves the checking of the
overall product.Have dynamic activities as it includes
executing the software against the requirements.Done by Testers.
Verification: typically involves reviews and meetings to evaluate documents, plans, code, requirements, and specifications. This can be done with checklists, issues lists, walkthroughs, and inspection meetings.
Validation: typically involves actual testing and takes place after verifications are completed. The term 'IV & V' refers to Independent Verification and Validation

relase. 2. when a new feature is added to the existing
application we need to add new test cases but after that do
we need to change all the existing test cases and while
running do we need to exicute entire application test cases
or only the new feature test cases and related new feature
test cases. 3.do you have any situation where you have to

follow.does it happens in real time. 4.example of bug which
is not reproducible.like tester say that there is bug and
developer say no can some example of such bugs. 5.during
regression testing some times do we need to add new some
