been fully developed.Each work-product or activity is

Answer / arun
As most of you have said, In the waterfall model each sterp
is frozen before the next step. that is the requirements
are frozen before the design starts, and once the design is
frozen the coding starts etc. But what will the testing
team do till then?????
In V model, based on the requirements the System test
cases are prepared, and based on the HLD (High level
document)the Integration Test cases are prepared, and based
on the LLD(Lowlevel document)the Integration Test cases are
prepared. and then the coding is done. once coding is
completed, unit, integration and system testing happens in
the sequence.

Differences In V-Model and Waterfall Model
In Waterfall Model the tester role will take place only in the test phase but in V-Model role will take place in the requirement phase itself
Waterfall madel is a fixed process u can't make any changes in the requirement or in any phase.but in V-Model u can make any changes in the requirements
V-model is the simultaneous process but it is not in case of water fall model
waterfall model used only the requirements are fixed but V-model can be used for the any type of requirement(Uncertain requirement)
