Stub is a part of Intgeration Testing
Intergration Testing

1>Top down-Use stubs to test the module
Stub is a dummy module replaced in order to test the main
module so that we are sure that the integration between
both the modules works fine

2>Bottom Up-- Use driver to test the module
the test data is sent to main module thru the drivers(also
called Test Harness)

It is only used for testing
Stub is used in Intgeration Testing ie Top down Integration
Testing

Top Down Testing:- It begins by testing the top level
module and progressively adds in lower level module one by
one. Some times the developer has till not developed the
main module, At that time the temparary module
is created that temparary module called "stub"

Answer / raghu

A dummy module is created in order to integrate modules of
an application and can be tested for the convinience of the
testers.
This is done usually in TOP down approach.

Answer / raj pavan

STUB:-
While integrating the modules in TOP DOWN APPROACH if at all any mandatory module is missing then that module is replaced with a temporary program is know as STUB

DRIVER:-
While integrating the module in BOTTOM UP APPROACH if at all any mandatory module is missing then that module can be replace with a temporary program is know as DRIVER

Answer / jaya

In Large Projects Development and Testing has
to be done simultaneously, so we need not wait
for all modules. Stubs are used in one such integration
testing known as Top Down integration testing,in
which Top modules are ready the bottom are stimulated by
stubs, stubs are nothing but prototype of a function
without any code.
