How do I use Mockito with JUnit for testing?

You can use Mockito with JUnit by adding the Mockito dependency to your project and using annotations like @Mock and @InjectMocks.

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

Sure! Here's a basic example:

import static org.mockito.Mockito.*;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.junit.MockitoJUnitRunner;

@RunWith(MockitoJUnitRunner.class)
public class MyServiceTest {
    @Mock
    private MyRepository myRepository;

    @InjectMocks
    private MyService myService;

    @Test
    public void testGetData() {
        when(myRepository.getData()).thenReturn("Mock Data");
        String result = myService.getData();
        assertEquals("Mock Data", result);
    }
}

What are the benefits of using Mockito for testing?

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

Are there any limitations to using Mockito?

Yes, Mockito can only mock interfaces and classes, and it may not work well with final classes or static methods without additional tools.
