What is the difference between stubs and drivers in software testing?

Stubs and drivers are the two concepts are used when some of the required components or functions are still in development and not available for Testing.

Let’s consider, you have two features, Feature A and Feature B, which are dependant on each other.

Now you need to test Feature A, Which takes some of the data from Feature B, and Feature B is still in development so you need to create a Dummy Feature B which produces data or input to test Feature A. and you can proceed to test with Feature A.

Now this Dummy Feature B called Stubs

Now you need to test Feature B, Which takes some of the data from Feature A, and Feature A is still in development so you need to create a Dummy Feature A which produces data or input to test Feature B. and you can proceed to test with Feature B.

Now this Dummy Feature A called Driver

So Basically Stubs and Driver are used for the same purpose replacing the module which is not developed yet or in development and not available for testing.

Stubs and Drivers are helpful to reduce unnecessary delays in testing and make testing faster.
