Mockito

Mockito is a testing tool used in software development to create mock objects—simulated versions of real components or systems. These mocks allow developers to test specific parts of their code in isolation, ensuring that they behave correctly without relying on actual external dependencies like databases or web services. Mockito enables developers to specify expected behaviors and verify interactions, making tests more reliable and easier to maintain. Overall, it streamlines testing by providing a controlled environment to validate code functionality efficiently.
