Powermockito doNothing for method with arguments

Question

I\'ve developed an application in Java and I\'m trying to create unit tests using Powermockito (I should add that I\'m new to unit testing).

I have a class called Re

Maybe i can't undestand your question, but i believe it's necessary specify what must do the method, so if you don't specify thenReturn or thenThrow or whatever powerMockito doesn't know what have to do when read your real code, for example:

REAL CODE:

            IPager pag;
        IPagerData> dpag;
        pag = new PagerImpl();
        pag.setFiles(nombrefilesPaginador);
        pag.setInici(1);
        dpag = gptService.obtenirDeutes(idSubjecte, idEns, tipusDeute, periode, pag);

Testing real code by mockito:

        IPager pag = new PagerImpl();
        pag.setInici(1);
        pag.setFiles(0);
        when(serveiGpt.obtenirDeutes(eq(331225L),
         eq(IConstantsIdentificadors.ID_ENS_BASE), 
         Matchers.any(ETipusDeute.class),
         Matchers.any(EPeriodeDeute.class), 
         eq(pag)))
        .thenThrow(new NullPointerException(" Null!"));

If haven't specify the return my test will be fail. I hope it helps.
