How to write Unit Test for Hybris DAO Implementation - sql

Question

I am new with unit test and I am trying to test this method, but it did not manage to capture the query of the method, I only managed to get it to enter an exception but not to take the query and return it.
Is there a way to return "result.getResult().get(0)" in the unit test?
Thanks
#Override
public HouseModel findByCode(String code) {
var sQuery = "SELECT {h:pk} FROM {House as h} WHERE {h:id} = ?id ";
var query = new FlexibleSearchQuery(sQuery);
query.addQueryParameter("id", Objects.requireNonNullElse(code, ""));
SearchResult<HouseModel> result = flexibleSearchService.search(query);
return result.getResult().get(0);
}
Code Test:
#Test
public void testFindByCode() {
when(flexibleSearchService.search((FlexibleSearchQuery) any())).thenThrow(new RuntimeException("test"));
RuntimeException exception = new RuntimeException();
try {
var result2 = houseDAOImpl.findByCode("testcode");
} catch (RuntimeException e) {
e.printStackTrace();
exception = e;
}
boolean shouldtrue = exception.getMessage().equalsIgnoreCase("test");
System.out.println(exception.getMessage());
System.out.println(shouldtrue);
assertTrue(shouldtrue);
}

Hybris supports TransactionTest incase of interaction with db.
public class HouseDAOImpTest extends HybrisJUnit4TransactionalTest
{
private TypeService typeService;
private ModelService modelService;
private DeeplinkUrlDao dao;
private List<HouseModel> createdRules;
/**
* #throws java.lang.Exception
*/
#Before
public void setUp() throws Exception
{
createdRules = createHouses();
houseDAOImpl = (HouseFinderDao) Registry.getApplicationContext().getBean("houseFinderDao");
}
#Test
public void testFindByCode()
{
final HouseModel hm = houseDAOImpl.findByCode("testcode");
assertThat(hm.getCode(), is(equalTo(""testcode""));
}
private ModelService getModelService()
{
if (modelService == null)
{
modelService = (ModelService) Registry.getApplicationContext().getBean("modelService");
}
return modelService;
}
private TypeService getTypeService()
{
if (typeService == null)
{
typeService = (TypeService) Registry.getApplicationContext().getBean("typeService");
}
return typeService;
}
/**
* Creates the Houses.
*/
private List<HouseModel> createHouses()
{
final List<HouseModel> result = new ArrayList<HouseModel>();
final HouseModel houseModel1 = getModelService().create(HouseModel.class);
houseModel.setCode("testcode");
modelService.save(houseModel1);
// create other houses model and follow previous steps
result.add(houseModel1);
result.add(houseModel2);
result.add(houseModel3);
return result;
}
}
