Mock Static method with Demoiselle and Powermock/Mockito

Question

I’m trying to mock a Static method, but Powermock requires the use of a specific Runner (Powermockrunner) for the Static mock to work!

And for Demoiselle to work, you need to start Weld with Demoisellerunner, but the Junit API only accepts a single Runner.

@RunWith(PowerMockRunner.class) //DemoiselleRunner.class
@PrepareForTest(Fabrica.class)
public class MeuBCTest {

    @Inject
    private PrimeiroBC primeiroBC; //Não injeta com o PowerMockRunner
    private SegundoBC segundoBC;

    @Before
    public void setUp() {
        primeiroBC = Mockito.spy(primeiroBC);
        segundoBC = Mockito.mock(SegundoBC.class);
    }

    @Test
    public void testCamposObrigatoriosComSucesso() {

        PowerMockito.mockStatic(Fabrica.class);
        PowerMockito.when(Fabrica.createSegundoBC()).thenReturn(segundoBC);

        primeiroBC.fazerAlgo(); //Internamente este método chama o Fabrica.createSegundoBC() para executar outra operação.

        //verificações

    }
}

Initially I thought of creating my own Runner extending from Powermockrunner and adding Weld as it is done in Demoisellerunner.

There are some settings in Demoiselle or Powermock so you don’t need to create another Runner?

Answer 1

I have never used the Demoiselle Framework. However, the difficulty with multiple Runners is not uncommon and occurs with other frameworks.

One solution is to use the Powermockrule. According to the documentation:

Since version 1.4 it is possible to start Powermock using a Junit rule (Junit Rule) instead of PowerMockRunner and the annotation RunWith. (free translation)

Example of use:

@RunWith(DemoiselleRunner.class)
@PrepareForTest(Fabrica.class)
public class MeuBCTest {

     @Rule
     PowerMockRule rule = new PowerMockRule();

     ...

}

Answer 2

I once had an affair with Arquilian, and used the PowerMockRule also, but in this case was not used the Runner of Demoiselle. In the Demoiselle we follow the guidance of JUnit which is to extend BlockJUnit4ClassRunner. If it doesn’t work with the PowerMockRule maybe the solution is, as you commented, to create your own Runner. Who knows can not create a DemoiselleRunnerPowerMock? And if you don’t succeed alone in creating can open a case in: frameworkdemoiselle.gov.br

OBS: The utluiz commented that gave up the Demoiselle because of the frequencies of commits. Your analysis was in the repository of Github? Because we are no longer using Sourceforge SVN after version 2.
