V-n-V stands for Verification and Validation. These two Vs
are the components of V-model or Vertical Model.
V word is used to describe the model because since it
follows Development and Testing parallely, top to bottom,
vertically!!! And if u look into the model diagram, its
shown in V structure to give a good view for the model and
its name.
In V-model, the Development and Testing phases goes in-
hand. For every Development phase there is a Testing phase.
This model is very convenient and easy to adapt for a SDLC.
Based on the V-model, Testing starts from the requirement
phase itself. So, according to me, there is no other best
phase where u can start Testing other then starting right
from Requirement phase. Its always better to prevent the
defects migrating from the early stage of project then
finding them at Testing phase and land up in spending lots
of money rectifying the defect.
On the light side, Defects are our Hero...Without them we
would have been unemployed ;)
