Detailed explanation-1: -What is V Model? V model is also known as the Verification and Validation model. In the V model, the testing phase goes in parallel with the development phase. Thus, the testing phase starts right at the beginning of SDLC.
Detailed explanation-2: -V-Model in SDLC In this type of SDLC model testing and the development, the phase is planned in parallel. So, there are verification phases of SDLC on the side and the validation phase on the other side.
Detailed explanation-3: -V Model in Software testing is an SDLC model where the test execution takes place in a hierarchical manner. The execution process makes a V-shape. It is also called a Verification and Validation model that undertakes the testing process for every development phase.
Detailed explanation-4: -In the V-Model, the probability of total number of defects in the development of application is low as testing is done in parallel to the development. In the Waterfall Model, the probability of total number of defects in the development of application is high as testing is done post development.
