How to write junit for Collection<ReferenceSearch.Info>

Avatar

Level 4

Hi @everyone

 

At line collection<ReferenceSearch.Info> resultSet ... getting NPE in test class.

replicationType = Deactivate;

public void handleReferences(String path, ResourceResolver resourceResolver, String eventType) {
ReferenceSearch referenceSearch = new ReferenceSearch();
referenceSearch.setExact(true);
referenceSearch.setHollow(true);
referenceSearch.setMaxReferencesPerPage(-1);
Collection<ReferenceSearch.Info> resultSet = referenceSearch.search(resourceResolver, path).values();
String[] references = resultSet.stream().map(ReferenceSearch.Info::getPagePath).distinct().toArray(String[]::new);

Arrays.stream(references)
.filter(reference -> StringUtils.startsWith(reference, "/content/dam/content-fragment"))
.forEach(reference -> checkMarketValue(path, resourceResolver, reference, eventType));
}

How to write junit for this type of methods.?

 

Thanks

Moking replicationActionMockedStatic worked for me as it was giving NPE here.

@saurabh_kumar_02 , try using mockedConstruction to create a constructor, please find sample code

try (MockedConstruction refSearch = mockConstruction(ReferenceSearch.class)) {
      ReferenceSearch refSearch = new ReferenceSearch();
      when(refSearch.search(any(ResourceResolver.class), anyString()))
          .thenReturn(//mock object);
      // Your method call
    }

Refer for more details about mockedConstruction

Hi @sravs  thanks for reply but this is not working 

 

try (MockedConstruction refSearch = mockConstruction(ReferenceSearch.class)) {
ReferenceSearch refSearchx = new ReferenceSearch();
when(refSearchx.search(any(ResourceResolver.class), anyString()))
.thenReturn(refSearch);

i tried this code.

The error is at below line

 when(refSearchx.search(any(ResourceResolver.class), anyString()))
.thenReturn(refSearch)

You should return mock object of the return type of search method not the refSearch object, Create a mock object for 

java.util.Map<java.lang.String,ReferenceSearch.Info>

like 

 

@Mock
java.util.Map<java.lang.String,ReferenceSearch.Info> refSearchMap

 

 and update the statement 

when(refSearchx.search(any(ResourceResolver.class), anyString()))
.thenReturn(refSearchMap);
//write the when and thenReturn statements for the methods called on refSearchMap

@saurabh_kumar_02 , I didn't see any mock construction in your test class, please use mock construction for 

ReferenceSearch

as suggested in earlier comments to cover that method. Simple mock won't work here.
