What is Mockito verification and how does it work?

Mockito verification is a feature in the Mockito framework that allows you to check if certain methods were called on mock objects during a test.

Can you give me an example of how to use verification in a test?

Sure! You can use verify(mockObject).methodCall(); to check if methodCall() was invoked on mockObject.

What happens if the method was not called?

If the method was not called, Mockito will throw an AssertionError, indicating that the expected interaction did not occur.

Are there different types of verifications I can perform?

Yes, you can verify the number of times a method was called, check for specific arguments, and even verify interactions with multiple mocks.
