Junit Test for sling delegation pattern is not working

Hi, 

 

I am trying to write test for custom image component. Here is the model impl

 

@Model(
    adaptables = SlingHttpServletRequest.class,
    adapters = {Image.class, ComponentExporter.class},
    resourceType = ImageImpl.RESOURCE_TYPE,
    defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL
)
@Exporter(
    name = ExporterConstants.SLING_MODEL_EXPORTER_NAME,
    extensions = ExporterConstants.SLING_MODEL_EXTENSION
)
public class ImageImpl implements Image {

    public static final String RESOURCE_TYPE = "myproject/components/content/image/v1/image";

    @Self
    @Via(type = ResourceSuperType.class)
    @Delegate(excludes = ComponentDelegateExclusion.class)
    private com.adobe.cq.wcm.core.components.models.Image image;

    @ValueMapValue
    @default(booleanValues = false)
    private boolean alignCenter;

    @ValueMapValue
    @default(booleanValues = false)
    private boolean removeGap;

    @ValueMapValue
    @default(booleanValues = false)
    private boolean fluidImage;

    @Override
    public boolean getAlignCenter() {
        return alignCenter;
    }

    @Override
    public boolean getRemoveGap() {
        return removeGap;
    }

    @Override
    public boolean getFluidImage() {
        return fluidImage;
    }

    @Override
    public String getExportedType() {
        return RESOURCE_TYPE;

 

And this is my test class

 

@ExtendWith({AemContextExtension.class, MockitoExtension.class})
class ImageImplTest {

    private final AemContext context = new AemContextBuilder().plugin(CORE_COMPONENTS)
                                                              .build();
    private static final String TEST_BASE = "/components/image";

    private ValueMap jsonProperties;

    private Image image;
    @BeforeEach
    void setUp() {
        context.addModelsForClasses(com.adobe.cq.wcm.core.components.models.Image.class);
        context.addModelsForClasses(ImageImpl.class);
        context.load().json(TEST_BASE + "/image-comp.json", "/apps/" + ImageImpl.RESOURCE_TYPE);
        Resource imageResource = context.load().json(TEST_BASE + "/image.json", "/content/image");
        jsonProperties = imageResource.getValueMap();
        context.currentResource("/content/image");
        image = context.request().adaptTo(Image.class);
    }

    @test
    void getAlignCenter() {
        assertEquals(jsonProperties.get("alignCenter"), Boolean.toString(image.getAlignCenter()));
    }

    @test
    void getRemoveGap() {
        assertEquals(jsonProperties.get("removeGap"), Boolean.toString(image.getRemoveGap()));
    }

    @test
    void getFluidImage() {
        assertEquals(jsonProperties.get("fluidImage"), Boolean.toString(image.getFluidImage()));
    }

    @test
    void testResourceType() {
        assertEquals(jsonProperties.get("sling:resourceType"), image.getExportedType());
    }

}

 

The tests are working fine for custom properties I have added, but the  private com.adobe.cq.wcm.core.components.models.Image image is always null. I can't access any core components property. image-comp.json is the infinity.json of /apps/myproject/components/content/image/v1/image and image.json is the infinity.json from /content/***/image

How can I solve this?

Hi @Julkar__Naim ,

Try to write getter public function for all the core component private function and then try to access it in your JUNIT class. 
Also make sure you have these property mentioned in JSON resource file.
