How do I use Mockito with the Spring Testing Framework?

You can use Mockito in the Spring Testing Framework by annotating your test class with @RunWith(SpringRunner.class) and using @Mock to create mock objects.

Can you give me an example of a test case using Mockito?

Sure! Here's a simple example:

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

    @Mock
    private MyRepository myRepository;

    @InjectMocks
    private MyService myService;

    @Test
    public void testFindById() {
        when(myRepository.findById(1L)).thenReturn(Optional.of(new MyEntity()));
        MyEntity entity = myService.findById(1L);
        assertNotNull(entity);
    }
}

What are the benefits of using Mockito in Spring tests?

Mockito allows you to create mock objects, which helps isolate the unit of work and test it without relying on external dependencies, making your tests faster and more reliable.

Are there any limitations to using Mockito?

Yes, Mockito can only mock interfaces and classes that are not final. Additionally, it may not be suitable for testing complex interactions without proper setup.
