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

[2490242973]

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, what is the CustomTeaserTest.json can you please share it?

It is a content JSON https://github.com/arunpatidar02/com.aemlab.junitapp/blob/master/core/src/test/resources/com/aemlab/...  which is used in https://github.com/arunpatidar02/com.aemlab.junitapp/blob/master/core/src/test/java/com/aemlab/junit... test class

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