JUnit - Page model NullPointerException

[Nitin_laad]

Hi All, 

Trying to get Page model object (OOB) in JUnit test case, but getting NullPointerException (at line#75).
Am I missing anything in the implementation, any thoughts/suggestion please.

Hi @Nitin_laad ,

Please try below line.

PageModel model = context.request().adaptTo(PageModel.class);

If possible, please share json what you are referencing below. 

Thanks,

Sandeep.

Hi @Nitin_laad,

Please check the Model under test. In this case, PageModel.class - If any of the injects/references used in sling model is null in the context of test environment, then it will result in Model being null. 

We need to set those references used in Model to aemContext and then use it to get the Model object. 

Example : If a Model uses Externalizer service, then we need to set the Externalizer to aemContext first before instantiating the Model. 

Please share the PageModel.class if it is fine to share for further debugging.

Thank You Vijaylaxmi for your time, Here is the model definition....and related junit and json (modified version)

@Nitin_laad do you have the RunWith annotation set?

@RunWith(MockitoJUnitRunner.class)
public class ComponentTest {
    @Rule
    public final AemContext context = new AemContext(ResourceResolverType.JCR_MOCK);

    private Component component;
   
    @Test
    public void itShouldNotBeNull() {
         Resource componentContext = context.create().resource("/content/my-site/home/jcr:content/component", new ValueMapDecorator(ImmutableMap.<String, Object> of(
                "fakeProp", "example")));
        underTest = componentContext.adaptTo(Component.class);
        assertNotNulll(underTest);
    }
}

Thank You @BrianKasingli, tried with suggested option but no luck

Try again after making your Sling Model more simple. Change to :

@Model(adaptables = {
          SlingHttpServletRequest.class, 
          Resource.class
     }, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class PageModel implements Page {

}

 If this doesn't work, try to remove implements Page. Just seeing it your developer's environment is working at all. It might just be a coding convention issue.

I am able to successfully run below test case
