What is RSpec mocking and how do I use it?

RSpec mocking is a technique in Ruby testing that allows you to create test doubles, which can simulate the behavior of real objects.

Can you give me an example of how to create a mock in RSpec?

Sure! You can create a mock using allow or expect. For example: allow(object).to receive(:method_name).and_return(value).

What is the difference between a mock and a stub?

A mock is used to set expectations on how an object should be used, while a stub is used to provide predefined responses.

When should I use mocking in my tests?

Use mocking when you want to isolate the unit of code being tested and avoid dependencies on external systems.
