what is the difference between V model and Waterfall model
used in SDLC?

Answer Posted / 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.

I know functional test cases are derived from frs and system design specs. But are test cases for performance, database, boundary, relational integrity and other types of tests other than functional tests created from frs and system design specs as well? When are these test cases created? Are they in the same test plans alongside functional test cases or is their a different test plan that includes these test cases?
