AEM Java unit test , adapt resource without jcr:title to model ?

In an AEM Java unit test , is it possible to adapt a resource without jcr:title to a model ?

In example below , testEmptyPage() is behaving as expected , but testEmptyPageMissingTitle() is not behaving as expected because it sets pageBean to null ?

In an AEM Java unit test , how can I adapt a resource without jcr:title to a model ?

Thank you and best regards.

The problem is your SlingModel. And from my point of view making fields optional is rarely the solution to such problems. 

 

From my point of view the problem is the missing registration of the SlingModel classes in the AemContext object. Please check the documentation at https://wcm.io/testing/aem-mock/usage.html#Sling_Models

    Hi Suresh,

    Thank you for suggestion. I tried adding defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL to the model , and also tried adding defaultInjectionStrategy = DefaultInjectionStrategy.REQUIRED , unfortunately neither has solved the problem and unit test is reporting pageBean as null when jcr:title missing from loaded content.

     

    ********** Model with defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL **********

    @Model(adaptables = {Resource.class}, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL) public class PageBeanModel implements Serializable { @586265 @Named(JcrConstants.JCR_TITLE) @7392697 private String title; }

     

    ********** Model with defaultInjectionStrategy = DefaultInjectionStrategy.REQUIRED **********

    @Model(adaptables = {Resource.class}, defaultInjectionStrategy = DefaultInjectionStrategy.REQUIRED) public class PageBeanModel implements Serializable { @586265 @Named(JcrConstants.JCR_TITLE) @7392697 private String title; }

      can you try like this

      @586265
      @Named(JcrConstants.JCR_TITLE)
      @7392697
      @1497330(values="No Title")
      private String title;

      or

      @586265
      @Named(JcrConstants.JCR_TITLE)
      @ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)
      @1497330(values="No Title")
      private String title;

      for Sling Model class check the defaultInjection Strategy (Constructor Injection and Field level injection)

      For jcr:title is mandatory set to optional and try.

      defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL

        Hi @robertbailey1,

        Possible reason for model being null could be variables/objects used in the model is null (not letting it to instantiate)

        Cross check the same(In particular, check if jcr:title is mandatory injection) or please share the PageBeanModel class if possible to debug further.
