Hi Team,

We are trying to create junit for sling models where delegate pattern was used, but the core class reference always returns null.Is there any better way to create junit for such use case. Detailed error : java.lang.NullPointerException: Cannot invoke "com.adobe.cq.wcm.core.components.models.Navigation.getAccessibilityLabel()" because "this.navigation" is null.

Hi @NehaCMS ,

You can check the WKND project example for ImageList, It injects "com.adobe.cq.wcm.core.components.models.List"

https://github.com/adobe/aem-guides-wknd/blob/main/core/src/test/java/com/adobe/aem/guides/wknd/core...

Hope this helps!

Regards,

Nitesh
