The MapTo() method is used to map a SPA component to an AEM component by specifying the sling:resourceType of the AEM component as an argument. The MapTo() method should be called on the SPA component and not on a string. The secondargument of the MapTo() method is optional and can be used to provide an edit configuration for the SPA component.

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

<artifactId>maven-surefire-plugin</artifactId>

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.

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.

Code Quality testing and UI testing are two types of testing that are available OOB in AEM Cloud Manager Pipeline. Code Quality testing checks the code quality of the project using SonarQube and reports any issues or vulnerabilities. UI testing checks the functionality and usability of the project using Selenium WebDriver and reports any errors or failures.

To ensure that text pasted inside the Text component in AEM is stripped of all styling and formatting, you need to override the RTE (Rich Text Editor) plugin implementation and change the default paste behavior. The correct option to achieve this is defaultPasteMode=plaintext.

Steps to configure the RTE plugin for plain text pasting:

Locate the RTE Configuration: Find the existing configuration for the RTE or create a new one in the /apps directory of your AEM project.

Modify the Plugin Configuration: Add or update the configuration to include the defaultPasteMode parameter. The configuration might look something like this:

{

"jcr:primaryType": "nt:unstructured",

"features": "[text]",

"defaultPasteMode": "plaintext"

}

Apply the Configuration: Ensure that this configuration is applied to the Text component. This typically involves updating the component dialog or design dialog to reference the updated RTE configuration.

Test the Configuration: In the AEM author instance, open the page with the Text component and paste text using CTRL+V. The pasted text should now be stripped of all styling and formatting, adhering to the plaintext mode.

By setting defaultPasteMode to plaintext, you ensure that the RTE only accepts plain text input, removing any formatting that might come from external sources.

JUnit and Mockito are two unit testing dependencies that are generated by AEM archetype. JUnit is a framework for writing and running unit tests in Java. Mockito is a framework for creating and using mock objects in unit tests. AEM archetype also adds Apache Sling Mocks and AEM Mocks Test Framework by io.wcm as dependencies for unit testing.

When multiple configurations for the same PID are applicable, the configuration with the highest number of matching runmodes is applied. This is because the runmodes act as a filter to select the most specific configuration for a given environment. If there is a tie between two or more configurations with the same number of matching runmodes, the one that occurs first in the repository is applied.References:https://experienceleague.adobe.com/docs/experience-manager-65/deploying/configuring/configure-runmodes.html?lang=en#configuring-osgi-settings-per-runmode

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.

The includeCommerce property is a boolean flag that indicates whether to include Commerce Core Components in the project or not. If set to y, the command will generate a commerce module that contains specific Commerce Core Components and their dependencies. These components can be used to integrate AEM with Adobe Commerce platform or other commerce solutions.

The Auto Replicate via On Off Trigger Configuration is a feature that allows content to be replicated as soon as the On Time and Off Times are reached. This feature can be enabled by creating an OSGi configuration for the com.day.cq.wcm.core.impl.servlets.OnOffTimeServlet service. This service listens for changes in the On Time and Off Time properties of pages and triggers replication accordingly.
