Answer Posted / jyothinapa
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.
