Answer / rohituppal

Drivers are used in bottom up approach of integration testing.

Suppose there are 3 modules A, B & C as shown below

A
|-> B
|->C

Bottom up approach tests module C first then B then A
Now suppose module C & B are ready but module A is not ready.
So in this case instead of waiting for module A to get ready tester will write some piece of code so as to get the required output that module A expected to give. This is driver itself.
