Ch. 6.16: Stubs and Drivers

Question 1

What are stubs and drivers?

Answer 1

Stubs and drivers are very helpful tools for testing and debugging programs that use functions.

Question 2

What is a stub?

Answer 2

A stub is a dummy function that is called instead of the actual function it represents. It usually displays a test message acknowledging that it was called, and nothing more.

Question 3

What is a driver?

Answer 3

A driver is a program that tests a function by simply calling it. If the function accepts arguments, the driver passes test data. If the function returns a value, the driver displays the return value on the screen.
