Verification and validation model

V Model of Testing
This model is a must question in any interview upto 2 years .So Please be prepare.
The V-model is a software development process, which can be presumed to be the extension of the waterfall model. Instead of moving down in a linear way, the process steps are bent upwards after the coding phase, to form the typical V shape. The V-Model demonstrates the relationships between each phase of the development life cycle and its associated phase of testing.
 Please be prepare it is also known as verification and validation model. In this model when we start the Requirement  analysis , at that time only the role of testers come in project.
and at each phase , tester is involved.
