Mockito 5.20.0 Released: Enhancing Java Mocking for Cleaner Tests
Mockito, a popular Java mocking framework, has seen its latest version 5.20.0 released last week, on October 2, 2025. This update brings enhancements to its core features, making it easier to write clean and reliable unit tests.
Mockito's core concepts include mock objects, stubbing, and verification. Mock objects are simulated objects that mimic the behavior of real ones, allowing developers to test code in isolation. Stubs are used to pre-program the behavior of these mock objects, with common methods including when().thenReturn() and when().thenThrow(). Verification ensures that the expected interactions with the mock objects occur, using methods like verify() and argument matchers such as any(), anyInt(), anyString(), and isNull().
Mockito solves a common problem in testing a service class that depends on a database repository. By mocking the repository, developers can focus on testing the service logic without dealing with external dependencies. This leads to faster tests and cleaner code.
With its latest release, Mockito continues to provide key benefits such as isolated testing, faster tests, cleaner code, behavior verification, and seamless framework support. By following best practices like using the @Mock annotation, verifying important interactions, and keeping tests simple, developers can write clean, maintainable, and reliable unit tests. Mockito's open-source nature and wide usage make it a valuable tool for Java developers.
