What is Mockito and how do I use it?

Mockito is a mocking framework for Java that allows you to create mock objects for testing. It helps in isolating the code you want to test.

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

Sure! You can create a mock object using Mockito like this: MyClass myMock = Mockito.mock(MyClass.class);.

How do I verify interactions with the mock?

You can verify interactions using Mockito.verify(myMock).myMethod(); to check if myMethod was called on the mock.

What are some common use cases for Mockito?

Common use cases include testing service layers, isolating dependencies, and simulating external systems.
