Conventional V-Model represents the development process in
the form of a V shape. The right side of the V represents
the testing where the systems is validated against the
specifications defined on the left side. The meeting point
of the V represents the actual development

The V-model is a graphical representation of the systems
development lifecycle. 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.


The four main process phases – requirements, specification,
design and implementation – have a corresponding
verification and validation testing phase.Implementation of
modules is tested by unit testing, system design is tested
by integration testing, system specifications are tested by
system testing and finally acceptance testing verifies the
requirements.

The V-model gets its name from the timing of the phases.
Starting from the requirements, the system is developed one
phase at a time until the lowest phase, the implementation
phase, is finished. At this stage testing begins, starting
from unit testing and moving up one test level at a time
until the acceptance testing phase is completed.

Explanation:
It is a testing model,in which both testing and
developemont is done simultaneously.Whenever a module is
developed it is tested immediately.

Answer / indu

V-model is a classical software development and testing
process model. In each stage, the planning phase is
reffered to ensuring that the goals accurately meet the
user requirents.

Requirement analysis : In this phase User acceptanc
document is prepared

System design : System testing document.

Architecture design(HLD): Integration testing document

Program design(LLD): Unit testing

Hi Suja

I need More Explanation of V-Model

pl. Can you mail me to
sun_ramprasad@yahoo.com

Answer / sujatha

Hai
according to me
In V-Model testing starts with s/w dev it self

so while preparing the URS/BRS we can write the user
acceptance test cases
while preparing the SRS we can write the system test cases
while preparing the design we can write the integration
test cases
while preparing the coding we can write the unit test cases

is it always necessary to do white box testing before doing black box testing.wat ar applications where only white box is done not black box testing,and application where only black box is benifical not white box testing
