Answer
# 1
Stubs and drivers are nothing but codes or programs that we 
use for testing bottom up and top down testing.

For Bottom up testing we use drivers and for Top down 
testing we use stubs.

Stub is special purpose program which is used to simulate 
the activity of missing component.

Driver is special code to aid the integration or routine 
that calls particular component and passes test case to it.

Stub is used in The Top-Down Approach & Driver is Used in 
The Bottom-Down Approach


While integrating The Modules in Top-Down Approach if at 
all any Mandatory Module is Missing Then That Module is 
Replaced With Temparory Program Known as STUB



While integrating The Modules in Bottom-Up Approach if at 
all any Mandatory Module is Missing Then That Module is 
Replaced With Temparory Program Known as DRIVER
