how can u differentiate intgration test cases with functional test cases..

Answer / subbu malepati

Functional Tests:
1. Module testing - Component testing
EG: Tap =+

Integration:
1. Pairwise -testing - intergrating one piece with another.
Here u have tetscases w.r.t the data-flow between two
components.Eg: Pipe and a tap
===========+ so here u observe the flow of water,
rate/capacity etc.
So in intergration tetsing u observe the o/p and at one
end, but u feed the i/p at other end of another component.

Answer / preetha

Functional Testing:
functional testing is testing the exact functionality of
the application whether the application works (or)meet the
the requirements as specified , (ie) module wise (Each
module within the application should meet the functionality)
and even overall

Integration Testing:
Integration testing is testing the entire application
functionality that is once all the individual modules are
once integrated(combined) to form as a whole (where
bottom-up and Top-down testing is part of this integration
testing)

for ex)Let us consider mail box where creating a new
mail(functional testing of an individual module) is one of
the functionality of the mail box where once the mail is
created and once sent the mail should be in "Sent" folder
and moving to separate folders etc ..come under the
integration testing

Answer / pbalaji

Integration testing is the process of testing the entire
software from start to end as a whole, but functional
testing is intended to compare the actual functionality of
the software with the expected functionality.
