How can I use annotations for mocking in Mockito?

You can use annotations like @Mock, @InjectMocks, and @Spy in Mockito to simplify your test setup.

Can you give me an example of using @Mock?

Sure! You can annotate a field with @Mock, and Mockito will create a mock instance for you. For example:

@Mock
private MyService myService;

What about @InjectMocks?

@InjectMocks creates an instance of the class and injects the mocks into it. For example:

@InjectMocks
private MyController myController;

How do I initialize these annotations?

You need to use MockitoAnnotations.initMocks(this) in your setup method, or use JUnit 5 with MockitoExtension.
