Vmodel is the model that included verification and the
validation of the software testing verification perfroms by
audit, walkthough,review etc.

V Model is a popular Software development model.
It large number of resources to implement.

In v model every development stage will have corresponding 
testing stage.

Here test will be prepared in parallel with development 
phases.


i.e

After receiving  the business requirements are prepared 
then testing team will develop User acceptence Testcases.
But these testcases will be executed and the end of the 
project.

Here Business Requirements are very abstract in nature and 
it talks just about What user/customer actually needs.

System Requirement Specifications will be prepared From 
Business Requirements specifications.

SRS will be more elaborated then the Business requirements.
SRS tell what are system features need to be developped.

After seeing SRS Document Testing People will start 
preparing System Functional Testcases.

After receiving Highlevel Design Doc,Testing people will 
prepare the System Integration Testcases.

After seeing Low level Design doc,Development team willl  
will prepare the Component integration Testcases.

After coding development team will prepare uint testcases
and executes the unit test on the each individual unit or 
fnction.

Thus there is a mapping between the each development  phase 
with testing.

  V model is software developement life cycle model. v for 
verification and validation model.The main advantage of the 
v model is parallel processing 
verification means contacting the meeting and reviews.
validation means actual testing.
verification contain 4 stages 
1.Gathering req: To prepare the SRS document
2. HLD: To prepare the main functionality of the application
3. LLD: To prepare the sub functionality of the application
4.Pgm Spec: To explain the each and every functionality of 
the application
validation also contain 4 stages:
1. Unit testing: To test the appl based on the Pgm Spec
2.Integration Testing: To test the appl based on the LLD
3.System Testing: To test the appl based on the HLD
4.UAT : To the appli based on the Gathering the req
