What is the V-model?

Answer Posted / v.lokesh

Basically this model is used to avoid defects r bugs in the
application and cost effective purpose,In this model we
will start the testing from begining of the project like
conducting the reviews on FRS,whether customer given all
requiremnts for developing the application r
not,understanding the system requirementsm i.e from
verfication(review) to validation(executing the code)

verifiaction-business requirements-system requirements-High
level design-low level design-Coding-unit testing-
integration testing-system testing-user acceptance testing-
validation

From system requirements stage we will start testing.
here we can ensure that right product is developed r not
during early stages and at every levels we can find the
defect and fix the defect,and at last the obtained product
is defect free......
