explain v-model

Answer Posted / manika mathur

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

Business Requirements Acceptance Testing
\ /
SRS SYSTEM TESTING
\ /
HLD INTEGRATION TESTING
\ /
LLD UNIT TESTING
\ /
CODING

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.

Our software designers use UML for modeling applications. Based on their use cases, we would like to plan a test strategy. Do you agree with this approach or would this mean more effort for the testers.
