How can I test my Spring Boot application using Mockito?

You can use Mockito to create mock objects for your Spring Boot tests, allowing you to isolate the components you're testing.

Can you show me a simple example of a test case?

Sure! Here's a basic example:

@RunWith(SpringRunner.class)
@SpringBootTest
public class MyServiceTest {

    @Mock
    private MyRepository myRepository;

    @InjectMocks
    private MyService myService;

    @Test
    public void testGetData() {
        when(myRepository.findData()).thenReturn(new Data());
        Data result = myService.getData();
        assertNotNull(result);
    }
}

What annotations do I need to use with Mockito?

You typically use @Mock to create mock objects, @InjectMocks to inject those mocks into the class under test, and @RunWith(MockitoJUnitRunner.class) or @SpringBootTest for Spring context.

Are there any best practices for using Mockito in Spring Boot?

Yes, some best practices include keeping your tests isolated, using meaningful names for your mocks, and verifying interactions with your mocks.
