Stubs and Driver comes under integration testing.
integration testing means integrating the modules and
perform testing on that.
integration testing can be performed in 3 approaches
1.Top-Down approach
2.Bottom-Up approach
3.Hybrid approach
Top-Down approach means integrating the main module with
the sub module.during this time if some of the sub modules
are not finished that is if they are in
underconstruction,to continue the integration testing we
will put one stub in the place of constructive sub module.
In bottom-up approach the integration is performed from
bottom to up.here sub modules are integrated with main
module.during this time if main program is not ready that
time we will put driver instaead of main program for
continuing integration testing once they are fully
constructed the main program we aill replace that driver
with the main program.

Answer / jyothi
At the time of integration development team finds one of
the sub module is yet to be released from unit testing then
they install a virtual environment is called 'stub'nd
continues integration testing based on main module in top
down manner
if main module is yet to be released from unit testing then
they continues integration testing in bottom up approach by
installing 'driver' in place of main module

i will give a gen example....suppose u have 3 modules...A B
C...A n B r 100% comp....and C is only 50% comp....u r under
pressure to comp in a time frame...what u do is u know to
build the mod C u need at least 15 days...so u build a dummy
mod C which wil take 1/2 days...This is STUB
now once all the mod A B and C(dummy) r ready..u integrate
them to see how it works..This is a DRIVER

Answer / dilip
Stubs and driver are dummy program written bt the
programmer when the real component are not reday for
testing.
Drivers are nothing but calling program and stubs are
called program.
