Hi @anilkumar9 ,
Writing JUnit test cases for a Sling Model that retrieves content fragment data involves several steps. Here’s a comprehensive guide on how to achieve this using JUnit 5.
Step-by-Step Guide
Set Up Your Maven Dependencies: Make sure you have the necessary dependencies in your pom.xml for JUnit 5, Sling Models, and AEM Mocks. Here’s an example configuration:
<dependency>
<groupId>org.apache.sling</groupId>
<artifactId>org.apache.sling.models.api</artifactId>
<version>1.4.0</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.sling</groupId>
<artifactId>org.apache.sling.models.impl</artifactId>
<version>1.4.6</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>io.wcm.testing.aem-mock</groupId>
<artifactId>aem-mock-junit5</artifactId>
<version>2.5.0</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-engine</artifactId>
<version>5.7.1</version>
<scope>test</scope>
</dependency>
Create the Sling Model: Assume you have a Sling Model that looks something like this:
import org.apache.sling.api.resource.Resource;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.models.annotations.injectorspecific.ValueMapValue;
@Model(adaptables = Resource.class)
public class ContentFragmentModel {
@ValueMapValue
private String fragmentPath;
public String getFragmentPath() {
return fragmentPath;
}
// Method to retrieve content fragment data
public String getContentFragmentData() {
// Logic to retrieve content fragment data
return "mockFragmentData";
}
}
Write the JUnit Test Case: Here’s how you can write a JUnit 5 test case for the above Sling Model using AEM Mocks.
import io.wcm.testing.mock.aem.junit5.AemContext;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.models.spi.Injector;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import io.wcm.testing.mock.aem.junit5.AemContextExtension;
import static org.junit.jupiter.api.Assertions.*;
@ExtendWith(AemContextExtension.class)
public class ContentFragmentModelTest {
private final AemContext context = new AemContext();
private ContentFragmentModel contentFragmentModel;
@BeforeEach
void setUp() {
// Set up the resource
context.create().resource("/content/testFragment",
"fragmentPath", "/content/dam/myFragment");
// Adapt the resource to the model
Resource resource = context.resourceResolver().getResource("/content/testFragment");
contentFragmentModel = resource.adaptTo(ContentFragmentModel.class);
}
@Test
void testGetFragmentPath() {
assertNotNull(contentFragmentModel);
assertEquals("/content/dam/myFragment", contentFragmentModel.getFragmentPath());
}
@Test
void testGetContentFragmentData() {
assertNotNull(contentFragmentModel);
assertEquals("mockFragmentData", contentFragmentModel.getContentFragmentData());
}
}
- Dependencies: We include necessary dependencies for Sling Models, AEM Mocks, and JUnit 5.
- Sling Model: A simple Sling Model (ContentFragmentModel) is created with a field fragmentPath.
- JUnit Test Case:
- AemContext: AEM Mocks provide AemContext to simulate AEM environment.
- Setup: In the setUp method, we create a resource and adapt it to our Sling Model.
- Test Methods: We then write test methods to verify the functionality of our Sling Model.
Running the Tests
Ensure you run your tests using a Maven command like:
mvn clean test
This setup provides a foundation to write comprehensive unit tests for Sling Models that interact with content fragments in AEM. Adjust the ContentFragmentModel and test cases based on the actual logic and fields in your Sling Mode
