Erro Unit Test [Wanted but not invoked] mockito

Question

Doubt: Good Night,

I'm doing some testing on my service and I'm having trouble performing the test in the delete method.

I wonder if anyone ever had this error and can be helping me.

The error occurs when I do the scan. What is reported is that the method was not using.

Exception:

Wanted but not invoked:
usuariosRepository.findRow(5);
-> at br.com.fortalezaserv.services.impl.tests.RepositoryUsuariosServiceTest.deveExcluirPorId(RepositoryUsuariosServiceTest.java:74)

However, there were other interactions with this mock:

Answer 1

You have not added MockitoJUnitRunner in @RunWith clause. Since you already have SpringJunitRunner you cannot add another one ( link for details ).

As an alternative, try MockitoAnnotations.initMocks(this); in the @Before 's setUp method.

Also one more suggestion, looks like you have added setters in your RepositoryUsuariosService service for testing. Avoid that by using @Mock annotation to mock UsuariosRepository class and then @InjectMocks in RepositoryUsuariosService which automatically inserts all the mocks.

Answer 2

I solved the problem here.

It was a failure of my logic, my delete function don't have return. That method don't performs any query to delete.

I then switched to the test:

@Test
public void deveExcluirPorId() throws QualityException {
    usuarioService.excluir(ID);
    verify(usuariosRepositoryMock, times(1)).delete(ID);
    verifyNoMoreInteractions(usuariosRepositoryMock);
}

Thanks!
