What are mocking libraries and how do they work?

Mocking libraries are tools used in software testing to simulate the behavior of complex objects. They allow you to create mock objects that mimic the behavior of real objects in controlled ways.

Why would I need to use a mocking library?

Using a mocking library helps isolate the code being tested, making it easier to test specific functionalities without relying on external systems or components.

Can you give me an example of a popular mocking library?

Sure! One popular mocking library is Mockito, which is widely used in Java applications for creating mock objects.

How do I set up Mockito in my project?

To set up Mockito, you need to add the Mockito dependency to your project’s build file, like Maven or Gradle, and then you can start creating mock objects in your tests.
