Java – use mockito to simulate enumeration?

I need to simulate the following enumeration:

public enum PersonStatus
{
    WORKING,HOLIDAY,SICK      
}

This is because it is used in the following classes I am testing:

Tested team:

public interface PersonRepository extends CrudRepository<Person,Integer>
{
    List<Person> findByStatus(PersonStatus personStatus);
}

This is my current test attempt:

Current tests:

public class PersonRepositoryTest {

    private final Logger LOGGER = LoggerFactory.getLogger(PersonRepositoryTest.class);

    //Mock the PersonRepository class
    @Mock
    private PersonRepository PersonRepository;

    @Mock
    private PersonStatus personStatus;

    @Before
    public void setUp() throws Exception {

        MockitoAnnotations.initMocks(this);
        assertThat(PersonRepository,notNullValue());
        assertThat(PersonStatus,notNullValue());
    }

    @Test
    public void testFindByStatus() throws ParseException {

        List<Person> personlist = PersonRepository.findByStatus(personStatus);
        assertThat(personlist,notNullValue());
    }
}

Which gives the following error:

Error:

org.mockito.exceptions.base.MockitoException: 
Cannot mock/spy class PersonStatus
Mockito cannot mock/spy following:
  - final classes
  - anonymous classes
  - primitive types

How can I solve this problem?

Solution

Your testfindbystatus tried to assert that findbystatus does not return null

If the method works in the same way, regardless of the value of personstatus param, just pass one of them:

@Test
public void testFindByStatus() throws ParseException {
    List<Person> personlist = PersonRepository.findByStatus(WORKING);
    assertThat(personlist,notNullValue());
}

If other possible values may behave differently, you can test each value:

@Test
public void testFindByStatus() throws ParseException {
    for (PersonStatus status : PersonStatus.values()) {
        List<Person> personlist = PersonRepository.findByStatus(status);
        assertThat(personlist,notNullValue());
    }
}
