Mockito

Mockito is a popular open-source Java testing framework used for creating mock objects in unit tests. It allows developers to simulate the behavior of complex dependencies, enabling isolated testing of individual components by stubbing method calls and verifying interactions. This helps ensure code reliability and maintainability by focusing tests on specific units without relying on external systems.

Also known as: Mockito Framework, Mockito Java, Mockito Testing, Mockito Mocking, Mockito Lib

🧊Why learn Mockito?

Developers should learn Mockito when writing unit tests for Java applications, especially in projects using dependency injection or complex object interactions, as it simplifies test setup and improves test isolation. It is particularly useful in test-driven development (TDD) and behavior-driven development (BDD) scenarios, such as mocking database connections, external APIs, or services to test business logic independently.
