Mockito。 正在创建的内部对象中的方法调用计数

Question

I have some class and method:

class Verificator {

   private Dao dao;
   private VerifyConsts verifyConsts;

   @Autowired
   public Verificator(Dao dao, VerifyConstants verifyConsts) {
        this.dao = dao;
        this.verifyConsts = verifyConsts;
   }

   public List<Pair<Products, Problem>> verify(final List<Product> links) {
     //do smth
     return new ProductVerifyLink().verifyLinks(links, verifyConstants.getForisInstanceZoneId(), dao.getDate());
   }

}

I have another class:

public class ProductVerifyLink {

    public List<Pair<Products, Problem>> verifyLinks(List<Product> links,
            final ZoneId zone,
            final Timestamp date
    ) throws Exception {
        //do smth
        List<Pair<Product, Problem>> res = verification(ImmutableList.of(links), zone);
        return res.isEmpty() ? null : res;
    }

    private List<Pair<Product, Problem>> verification(List<Product> links, ZoneId zone) {
      //do smth
    }
    //other methods
}

I created test:

    @Test
    public void calcTest() throws Exception {   
        final DAO dao = mock(DAO.class);
        final VerifyConstants verifyConsts = mock(VerifyConstants.class);
        final Verificator verifyLinks = Mockito.spy(new Verificator(dao, verifyConsts));

        final List<Product> links = ImmutableList.of(
                createUmrsLink(true, 2042229422, dateTime));
        final List<Long> linkIds = links.stream().map(Product::getProductId).collect(Collectors.toList());

        final List<Pair<ProductUmrs, VerifyProblem>> pairs = verifyLinks.verify(links);
    }

I want to check that method ProductVerifyLink.verification called once and with the arguments necessary to me. How can use Mockito and JUnit make it?

The whole problem is that the object of this class ( ProductVerifyLink ) is created inside, and outside I can not influence it.

Answer 1

You can't verify private methods with mockito, hence you can do it with PowerMock

But I can suggest you to test return of your public method, so you do also test get through your flow including private methods.
