Hi @nats ,
Here is the approach which you can go through step by step to do unit testing for the sling model by using Junit5 and AEM Mocks .
->Make sure your project is set up with the necessary dependencies for JUnit 5 and AEM Mocks. You can add the required dependencies to your project's Maven or Gradle build file.
->Ensure that your Sling Model class is implemented correctly and has the necessary logic to retrieve the root page and access child pages.
->Create a JUnit 5 test class for your Sling Model. This class will be responsible for testing the behavior of your Sling Model.
->In your test class, use AEM Mocks to set up a mock AEM environment that simulates the AEM context. This includes mock requests, resource resolver, and other AEM-specific objects.
->Set up a mock AEM page structure with a root page and child pages that your Sling Model will use during testing.
->Write test methods in your test class to test the behavior of your Sling Model. Use JUnit 5 assertions to verify that the Sling Model behaves as expected.
Sharing an example of how to write a simple unit test for a Sling Model that retrieves child pages under a root page.
Assuming you have the following Sling Model class that retrieves child pages:
@Model(adaptables = SlingHttpServletRequest.class)
public class MyComponentModel {
@Inject
private PageManager pageManager;
private List<Page> childPages;
@PostConstruct
protected void init() {
// Get the root page (assumed to be the current page in this example)
Page currentPage = pageManager.getContainingPage(request.getResource());
// Get the child pages of the root page
childPages = currentPage.getChildren();
}
public List<Page> getChildPages() {
return childPages;
}
}
->let's create a test class for this Sling Model.
import io.wcm.testing.mock.aem.junit5.AemContext;
import org.apache.sling.api.SlingHttpServletRequest;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.osgi.framework.BundleContext;
import org.osgi.service.component.annotations.Reference;
import static org.junit.jupiter.api.Assertions.*;
import static org.mockito.Mockito.*;
@ExtendWith(AemContextExtension.class)
public class MyComponentModelTest {
private MyComponentModel myComponentModel;
@BeforeEach
void setUp(AemContext context, SlingHttpServletRequest request) {
// Set up your mock AEM context
// Example: Set up a mock page structure with a root page and child pages
Page rootPage = context.create().page("/content/mysite");
context.create().page(rootPage, "child1");
context.create().page(rootPage, "child2");
// Create an instance of your Sling Model
myComponentModel = new MyComponentModel();
myComponentModel.pageManager = mock(PageManager.class);
// Set up mock behavior for PageManager to return the root page
when(myComponentModel.pageManager.getContainingPage(request.getResource())).thenReturn(rootPage);
}
@Test
void testGetChildPages() {
// Call the init() method to trigger the retrieval of child pages
myComponentModel.init();
// Get the list of child pages from the Sling Model
List<Page> childPages = myComponentModel.getChildPages();
// Assert that the list of child pages is not null and contains the expected number of pages
assertNotNull(childPages);
assertEquals(2, childPages.size());
}
}
Hope this helps !
