it's still a problem, How to Unit test case for Sling delegation pattern?

It's still a problem. I am using the latest AEM Maven Archetype to customize the Teaser component, but unable to pass my tests because of the delegation pattern. I scaveraged through the net and have already reviewed all the possible answers like:

@arunpatidar and other folks, can you please help me out by giving me a working version of a Delegation pattern?

 

Here's a very simple sling model component that needs JUNIT5. I am also on the latest AEM 6.5 version + Latest AEM Maven Archetype version

 

@Model(adaptables = SlingHttpServletRequest.class, resourceType = CustomTeaser.RESOURCE_TYPE, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL) @Exporter(name = ExporterConstants.SLING_MODEL_EXPORTER_NAME, extensions = ExporterConstants.SLING_MODEL_EXTENSION) public class CustomTeaser implements com.adobe.cq.wcm.core.components.models.Teaser { public static final String RESOURCE_TYPE = "mycomp/components/customteaser"; @Self @Via(type = ResourceSuperType.class) private com.adobe.cq.wcm.core.components.models.Teaser teaser; @Override public String getTitle() { return teaser.getTitle(); } }

 

Whenever I am using AEMContext or Mocks, while in debug mode, teaser is ALWAYS NULL.

      Hello @brianli1 ,

      Please follow my article. I gave two examples for considering different cases. (Breadcrumb & Language Navigation).

      Hope this will help you and your problem will be solved.

      The main problem of the delegation pattern you just mention is null. This is solved.

        Hi @sady_rifat,

        Thanks for the details documentation. I am trying to extend the title component here and still getting Error :

        Caused by: org.apache.sling.testing.mock.osgi.ReferenceViolationException: Unable to inject mandatory reference 'externalizer' for class com.adobe.cq.wcm.core.components.internal.link.DefaultPathProcessor : no matching services were found.

        . 
        Below is the code for the test class and related classes. 

         

        @ExtendWith({AemContextExtension.class, MockitoExtension.class}) class TitleImplTest { public static final String COMPONENT_PATH = "component_path"; public static final String COMPONENT_CONTENT_PATH = "content_path"; public final static String PAGE_PATH = "page_path"; private final AemContext ctx = AppAemContext.newAemContextForCore(); private Title title; /** * Setup aem context with resource and models. */ @BeforeEach void setUp() { // Load all sling models to AEM context ctx.addModelsForClasses(Title.class); // Load Page resource with component to context ctx.load().json("/models/TitleImplTest/TitleImplTest.json", PAGE_PATH); // Load Component to context for delegation pattern ctx.load().json("/models/TitleImplTest/Component.json", COMPONENT_PATH); // Set Current path to component under page ctx.currentResource(COMPONENT_CONTENT_PATH); // Adapt request to Sling Model title = ctx.request().adaptTo(Title.class); } /** * Test Title Impl methods. */ @Test void testTitleImpl() { // Validate all fields/methods assertEquals("Explore Process Optimization", title.getText(), "Verify title text"); assertFalse(title.enableAnchor(), "Verify anchor disabled"); assertEquals("explore-process-optimization", title.getAnchorID(), "Verify anchor id"); assertEquals("/jcr:content/root/responsivegrid/container/title", title.getMeta().getComponentRelativePath(), "Verify component relative path"); }

         

         

         

        public static AemContext newAemContextForCore() { return new AemContextBuilder().resourceResolverType(ResourceResolverType.JCR_MOCK) .plugin(CORE_COMPONENTS).build(); }

         

         

         

        @Delegate(types = com.adobe.cq.wcm.core.components.models.Title.class, excludes = Handled.class) @Self @Via(type = ResourceSuperType.class) private com.adobe.cq.wcm.core.components.models.Title delegate;

         

         

        Appreciate your response.
