AemMock in JUnit4 is not able to return page.getTemplate

[RRaj]

I am trying to run the test for one of my Model class for Custom Render Condition. Its testing if current is a template allowed to show the tab/field in dialog. When I am running test for this code using AemMock and JUnit4 its failing when debug I found its not able to get template from the page object: 

            final Template pageTemplate = page.getTemplate();
//The above, getTemplate returns null for my Unit test below
            templatePathOfCurrentPage = pageTemplate.getName();

But at the same time if I change the code for getting the template with Resource API it works perfectly fine:

            Resource pageResource = page.getContentResource();
            templatePathOfCurrentPage = pageResource.getValueMap().get("cq:template", String.class);

Any pointer on this or suggestion to solve this will highly appreciated.

This is my Unit test:

package com.abc.models;

import com.adobe.granite.ui.components.rendercondition.SimpleRenderCondition;

@RunWith(MockitoJUnitRunner.class)
public class TemplateTypeRenderConditionTest {

    private static final String DEST_ROOT = "/content/sample/abc";
    private static final String TEMPLATE_PATH = "/conf/abc/settings/wcm/templates/homepage";
    private static final String PAGE_ROOT = "/content/sample/abc/index";

    
    public final AemContext CONTEXT = AppAemContext.newAemContext();

    @Mock
    PageManager pageManager;

    SlingHttpServletRequest request;
    SlingBindings slingBindings;


    @Before
    public void setUp() throws NoSuchFieldException, WCMException {

        slingBindings = (SlingBindings) CONTEXT.request().getAttribute(SlingBindings.class.getName());
        slingBindings.put(WCMBindings.PAGE_MANAGER, pageManager);
        slingBindings.put(SlingBindings.RESOURCE, CONTEXT.resourceResolver().getResource(DEST_ROOT));

        // prepare sling request
        CONTEXT.request().setAttribute(SlingBindings.class.getName(), slingBindings);
        CONTEXT.request().setResource(CONTEXT.resourceResolver().getResource(DEST_ROOT));
        CONTEXT.pageManager().create(DEST_ROOT, "index", TEMPLATE_PATH, "title1");
    }
    
    public void itShouldReturnTheResourceMatchesTheTemplateTypeFromItemParamter() throws WCMException {
        CONTEXT.request().setQueryString("item="+PAGE_ROOT);
        CONTEXT.getService(ModelFactory.class).createModel(CONTEXT.request(), TemplateTypeRenderCondition.class);
        final SimpleRenderCondition resultingRenderCond = (SimpleRenderCondition)  CONTEXT.request().getAttribute(RenderCondition.class.getName());

        assert(resultingRenderCond.check());
    }
}

Apps AEM Context setup:

package com.abc.models;

import org.apache.sling.api.resource.PersistenceException;
import org.apache.sling.testing.mock.sling.ResourceResolverType;
import java.io.IOException;

public class AppAemContext {
    private static final String DEST_ROOT = "/content/sample/abc";
    private static final String TEST_JSON = "/templatetyperendercondition/test-content.json";
    public static AemContext newAemContext() {
        return new AemContext(new SetUpCallback(), ResourceResolverType.JCR_MOCK);
    }

    private static final class SetUpCallback implements AemContextCallback {

        
        public void execute(AemContext context) throws PersistenceException, IOException {
            // application-specific services for unit tests
            context.registerService(AdapterFactory.class, new MockAemAdapterFactory());
            context.registerService(new AemObjectInjector());

            // register models from package
            context.addModelsForPackage("com.abc.models");
            context.load().json(TEST_JSON, DEST_ROOT);
        }
    }
}
