JUnitParams with Mockito

This could be a XY problem but I want to ask:

I am using JUnitParams to be able to run my test method 10 times with different objects. The problem is that the injections don’t work (@Mock and @InjectMocks). I can use

PersonService personService = mock(PersonServiceImpl.class)

to mock the PersonService in the @Test method. But how do mock the “main” object that is annotated with @InjectMock? Maybe it is not possible and JUnitParams was only created for simple test cases that they exemplify with on their site.

If I can’t use JUnitParams, what can I do instead? I have tried

@RunWith(value = Parameterized.class)

but that doesn’t work either.. I think..

What I have:

@RunWith(JUnitParamsRunner.class)
public class SkapaKundMasterDataTest {

    @InjectMocks
    private SkapaKundMasterData batch;

    @Mock
    private PersonService personService;

    @Mock
    private UtbetalningService utbetalningService;

    @Mock
    private Användare user;

    public Collection<PersonA[]> paramz() {

        List<PersonA[]> params = new ArrayList<>();
        params.add(new PersonA[] {new PersonA(new PersonId(1111111111111L), new Personnummer(195001019999L), Datum.skapaDatum(1950, 1, 1), AllaArbetstagarFörEnPerson.utanArbetstagare(), null, null, null, null, null, false, null)});
        params.add(new PersonA[] {new PersonA(new PersonId(2222222222222L), new Personnummer(195102029999L), Datum.skapaDatum(1951, 2, 2), AllaArbetstagarFörEnPerson.utanArbetstagare(), null, null, null, null, null, false, null),});
        params.add(new PersonA[] {new PersonA(new PersonId(3333333333333L), new Personnummer(195203039999L), Datum.skapaDatum(1952, 3, 3), AllaArbetstagarFörEnPerson.utanArbetstagare(), null, null, null, null, null, false, null)});
        params.add(new PersonA[] {new PersonA(new PersonId(4444444444444L), new Personnummer(195304049999L), Datum.skapaDatum(1953, 4, 4), AllaArbetstagarFörEnPerson.utanArbetstagare(), null, null, null, null, null, false, null)});
        params.add(new PersonA[] {new PersonA(new PersonId(5555555555555L), new Personnummer(195405059999L), Datum.skapaDatum(1954, 5, 5), AllaArbetstagarFörEnPerson.utanArbetstagare(), null, null, null, null, null, false, null)});
        params.add(new PersonA[] {new PersonA(new PersonId(6666666666666L), new Personnummer(195506069999L), Datum.skapaDatum(1955, 6, 6), AllaArbetstagarFörEnPerson.utanArbetstagare(), null, null, null, null, null, false, null)});
        params.add(new PersonA[] {new PersonA(new PersonId(7777777777777L), new Personnummer(195607079999L), Datum.skapaDatum(1956, 7, 7), AllaArbetstagarFörEnPerson.utanArbetstagare(), null, null, null, null, null, false, null)});
        params.add(new PersonA[] {new PersonA(new PersonId(8888888888888L), new Personnummer(195708089999L), Datum.skapaDatum(1957, 8, 8), AllaArbetstagarFörEnPerson.utanArbetstagare(), null, null, null, null, null, false, null)});
        params.add(new PersonA[] {new PersonA(new PersonId(9999999999999L), new Personnummer(195809099999L), Datum.skapaDatum(1958, 9, 9), AllaArbetstagarFörEnPerson.utanArbetstagare(), null, null, null, null, null, false, null)});
        params.add(new PersonA[] {new PersonA(new PersonId(1234567891234L), new Personnummer(195910109999L), Datum.skapaDatum(1959, 10, 10), AllaArbetstagarFörEnPerson.utanArbetstagare(), null, null, null, null, null, false, null)});

        return params;
    }

    @Test
    @Parameters(method = "paramz")
    public void alltOk(PersonA dummy) throws BaseException {
        MockitoAnnotations.initMocks(SkapaKundMasterDataTest.class);
        //PersonService personService = mock(PersonServiceImpl.class); //this works
        when(personService.HämtaPersonAFörKundMasterdata(any(), any())).thenReturn(Optional.of(dummy));

        Properties p = new Properties();
        p.put("skummisar", "Ja");
        JobbParametrar params = JobbParametrar.skapa(p);

        batch.uppgift(dummy.getPersonId(), params, new KörningsId(0), any());
    }
}

You cannot have two different runners simultaneously, but you can setup Mockito with a Rule. Just add the following to your test class while keeping the JUnitParamsRunner:

@Rule
public MockitoRule rule = MockitoJUnit.rule();
