// Unit Testing Example
@ExtendWith(MockitoExtension.class)
class UserServiceTest {
    
    @Mock
    private UserRepository userRepository;
    
    @InjectMocks
    private UserService userService;

        // Then
        assertThat(result.getEmail()).isEqualTo("[email protected]");
        verify(userRepository).save(user);
    }
}

// Integration Testing Example
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
