How can I use Mockito with Spring Testing Framework?

How can I use Mockito with Spring Testing Framework?

You can use Mockito to create mock objects in your Spring tests. This allows you to isolate the unit of work and test it independently.

Can you show me an example of mocking a service in a Spring test?

Sure! You can use the @MockBean annotation to mock a service in your test class. Here's a simple example:

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

    @MockBean
    private MyService myService;

    @Autowired
    private MyController myController;

    @Test
    public void testGetData() {
        when(myService.getData()).thenReturn(new Data());
        // Call the controller method and assert the response
    }
}

What are some best practices for using Mockito in Spring tests?

Some best practices include:

1. Use @MockBean for Spring beans.
2. Keep your tests focused on one unit of work.
3. Avoid using real implementations in tests to ensure isolation.

How do I verify interactions with mocked objects?

You can use the verify() method provided by Mockito. For example:

verify(myService).getData();
``` This checks if `getData()` was called on the mocked service.
