V-Model
The V model (Validation & Verification model)[11] is
a modified version of the Waterfall method
As opposed to the Waterfall method, this one was not
designed in a linear axis; instead the stages turn back
upwards after the coding phase is done.
This developmental process is balanced and relies on
the verification from the previous steps before
proceeding forward.
The product from every phase needs to be checked
and approved before moving forward.
In v model developer and tester works parallel.
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(Low-level
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.
In V-model, gives relationship between each
development stages and Testing stages
