Embedding client libraries is a technique that allows combining code from multiple client libraries into a single file. This reduces the number of network requests and improves performance. Embedding client libraries can be done by using the embed property of the cq:ClientLibraryFolder node and specifying the categories of the client libraries to be embedded.

A mock framework is a tool that allows creating mock objects that simulate the behavior of real objects in a controlled way. A mock framework can be used in a unit test to inject the EmployeeService dependency into the CalculationService and verify its interactions. This way, the unit test can focus on testing the logic of the CalculationService without relying on the actual implementation of the EmployeeService.References: https://sling.apache.org/documentation/development/sling-testing-tools.html https://wcm.io/testing/aem-mock/usage.html

To implement a new component called "Page Headline" which takes the text from the current page title instead of jcr:title, you should create a proxy component from the core title component and implement a Sling Model accordingly. Option C demonstrates the correct approach to achieve this functionality.

Here is a detailed explanation of Option C:

Create Proxy Component:

Create a new component in your project that will act as a proxy to the core title component. This involves creating a new component node in the repository that inherits from the core title component.

Example path: /apps/myproject/components/pageHeadline with sling:resourceSuperType set to core/wcm/components/title/v2/title.

Implement Sling Model:

Implement a Sling Model that adapts from SlingHttpServletRequest and Title.class, ensuring it overrides the text fetching logic to retrieve the title from the current page's title.

The model will use @ScriptVariable to inject the current page and @Self to access the core title component's logic.

@Model(adaptables = SlingHttpServletRequest.class, adapters = Title.class, resourceType = "myproject/components/pageHeadline")

public class PageHeadline implements Title {

@ScriptVariable

private Page currentPage;

@Self @Via(type = ResourceSuperType.class)

private Title title;

@Override

public String getText() {

return currentPage.getTitle();

}

@Override

public String getType() {

return title.getType();

}

}

@Model Annotation: Specifies that this class is a Sling Model and adapts from SlingHttpServletRequest. It is also an adapter for Title.class and applies to the myproject/components/pageHeadline resource type.

@ScriptVariable: Injects the current Page object, which allows access to the current page's properties.

@Self @Via(type = ResourceSuperType.class): Injects the core title component, allowing the reuse of existing logic.

getText() Method: Overrides the getText() method to return the title from the current page instead of the jcr:title.

getType() Method: Delegates to the core title component's getType() method to maintain existing functionality.

This approach leverages the power of Sling Models and the core components to extend functionality while keeping the implementation clean and maintainable.

To generate a test coverage report for an AEM project using the latest archetype, the correct plugin to use is the maven-surefire-plugin (Option A). The maven-surefire-plugin is a part of the Maven ecosystem and is widely used to run unit tests within a Maven project. This plugin can be configured to generate detailed test reports, including HTML versions, which can be easily shared with clients.

Here’s how to configure the maven-surefire-plugin to generate test coverage reports:

Add the Plugin to the POM File: Add the maven-surefire-plugin configuration in your pom.xml file:

org.apache.maven.plugins

maven-surefire-plugin

2.22.2

${project.build.directory}/surefire-reports

html

false

Execute the Maven Command: Run the following command to execute the tests and generate the coverage report:

mvn clean test

Locate the Report: The HTML test coverage report will be generated in the target/surefire-reports directory of your project.

A proxy component is a site-specific component that inherits from a core component and allows customization of the component name, group, dialog, and behavior. A proxy component can refer to any version of the core component by changing the sling:resourceSuperType property. A custom sling model can be used to implement the logic for adding the page title as prefix to the text property. A component template can be used to define the layout of the component.
