I am trying to test a Model adaptable as SlingHttpServletRequest. Its basically a Custom RenderCondition checks for the Template of the page to show or hide dialog field/tab. It will be a great help if anyt one could point any issue in my test fixture, following the documents from io.wcm here - https://wcm.io/testing/aem-mock/usage.html#JUnit_4_AEM_Context_JUnit_Rule it should work on page.getTemplate() after adapting resource as Page.

I Now the test cases are failing Due to its not able to get the page.getTemplate(); it always returns Null but at the same time if I use resource API its can get "cq:template" as string and passes the test.

package com.abc.models;

@RunWith(MockitoJUnitRunner.class)
public class TemplateTypeRenderConditionTest {

    private static final String DEST_ROOT = "/content/sample/abc";
    private static final String TEMPLATE_PATH = "/conf/homepage/settings/wcm/templates/homepage";
    private static final String PAGE_ROOT = "/content/sample/abc/index";
    private TemplateTypeRenderCondition underTestModel;
    public final AemContext CONTEXT = AppAemContext.newAemContext();

    @Mock
    PageManager pageManager;
    SlingBindings slingBindings;
    Resource pageResource ;
    Page pageToTest = null;

    @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));
         CONTEXT.request().setAttribute(SlingBindings.class.getName(), slingBindings);

         // prepare sling request
         CONTEXT.request().setResource(CONTEXT.resourceResolver().getResource(DEST_ROOT));
         CONTEXT.request().setQueryString("item=/content/sample/abc/index");

         CONTEXT.pageManager().create("/content/sample/abc", "index", TEMPLATE_PATH, "title1");

    }
    
    public void itShouldReturnTheResourceMatchesTheTemplateTypeFromItemParamter() throws WCMException {
        
        CONTEXT.pageManager().create("/content/sample/abc", "index", TEMPLATE_PATH, "title1");
        pageResource = CONTEXT.resourceResolver().getResource(PAGE_ROOT);
        pageToTest = CONTEXT.pageManager().getPage(PAGE_ROOT);
        underTestModel = CONTEXT.getService(ModelFactory.class).createModel(CONTEXT.request(), TemplateTypeRenderCondition.class);
        assertEquals(pageToTest.getTemplate().getPath(),TEMPLATE_PATH);
        assertEquals(pageToTest.getResource().getValueMap().get("cq:template", String.class), TEMPLATE_PATH);

    }

}

The first assert is failing for getting template object but not the second one. Saying .getTemplate is returning null

My Unit test passes this assert

underTestModel = CONTEXT.getService(ModelFactory.class).createModel(CONTEXT.request(), TemplateTypeRenderCondition.class);

SimpleRenderCondition resultingRenderCond = (SimpleRenderCondition)  CONTEXT.request().getAttribute(RenderCondition.class.getName());
assertTrue(resultingRenderCond.check());

If I am using this code to get the Template in my class:

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

But fails if the AEM Page API being used for accessing template name:

          final Template pageTemplate = page.getTemplate();
          templatePathOfCurrentPage = pageTemplate.getPath();

        request.setAttribute(RenderCondition.class.getName(), new SimpleRenderCondition(show));
    }

    public String[] getTemplatePath(){
        return templatePath;
    }

}

I am trying to test it and so here is my Context setup for test:

package com.abc;

import com.abc.models.TemplateTypeRenderCondition;
import com.google.common.base.Function;
import io.wcm.testing.mock.aem.junit.AemContext;
import io.wcm.testing.mock.aem.junit.AemContextCallback;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.testing.mock.sling.ResourceResolverType;

import javax.annotation.Nullable;

public class AppAemContext {

    private static final String DEST_ROOT = "/content/sample/abc";
    private static final String TEST_JSON = "/templaterendercond/test-content.json";
    private static final String PAGE_ROOT = "/content/sample/abc/index";
    private static final String TEST_PAGE_JSON = "/templaterendercond/test-page.json";

    public static AemContext newAemContext() {
        return new AemContext(new SetUpCallback(), ResourceResolverType.JCR_MOCK);
    }

    private static TemplateTypeRenderCondition mockTemplateTypeRenderCondition  = new TemplateTypeRenderCondition();

    private static final class SetUpCallback implements AemContextCallback {

        
        public void execute(AemContext context) {
            context.registerAdapter(SlingHttpServletRequest.class,
                    TemplateTypeRenderCondition.class,
                    new Function<SlingHttpServletRequest, TemplateTypeRenderCondition>() {

                
                public TemplateTypeRenderCondition apply(@Nullable SlingHttpServletRequest request) {
                    return mockTemplateTypeRenderCondition;
                }
            });

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