Drivers and Stubs

It is always a good idea to develop and test software in "pieces". But, it may seem impossible because it is hard to imagine how you can test one "piece" if the other "pieces" that it uses have not yet been developed (and vice versa). To solve this kindof diffcult problems we use stubs and drivers.

Stub is a piece of code emulating a called function :-Stubs are created integration testing like Top-down approach
Driver is a piece of code emulating a calling function.Drivers are created integration testing like bottom-up approach
