Adobe AEM (Adobe Experience Manager) HTL2HTML compile and test
(AEM 6.1 soon to be moving to 6.3)

I would like to automatically generate HTML from HTL Components
as part of the build process (using default / and custom values )
so I can provide additional automated testing and quality assurance.
i.e. HTML validation and Accessibility QA.

Is there a java call, or some other command line tool that could generate html snippets or pages for each of the components.
Which could be incorporated into the build process when making a call to
mvn clean install -PautoInstallPackage

I have considered generating pages using selenium but I suspect that approach is slow and error prone.

Thanks for your help

You can get the rendered HTML on the server side using SlingRequestProcessor.

From @nateyolles blog post:

Getting the HTML markup for a resource in Apache Sling.

@SlingServlet(paths="/bin/foo")
public class SlingResourceResolutionServlet extends SlingSafeMethodsServlet {

 /** Service to process requests through Sling */
 @Reference
 private SlingRequestProcessor requestProcessor;

 @Override
 protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException 

 /* The resource path to resolve. Use any selectors or extension. */
 String requestPath = "/content/myapp/us/en/index/jcr:content/myparsys/mycomponent_f93d.html";

 /* 
 * Create a fake request and fake response. The response adds a method to make the HTML accessible.
 * You need the following three files from Apache Sling:
 *
 * https://github.com/apache/sling/blob/trunk/testing/junit/scriptable/src/main/java/org/apache/sling/junit/scriptable/HttpRequest.java
 * https://github.com/apache/sling/blob/trunk/testing/junit/scriptable/src/main/java/org/apache/sling/junit/scriptable/HttpResponse.java
 * https://github.com/apache/sling/blob/trunk/testing/junit/scriptable/src/main/java/org/apache/sling/junit/scriptable/TestServletOutputStream.java
 */
 final HttpRequest req = new HttpRequest(requestPath);
 final HttpResponse resp = new HttpResponse();

 /* Process request through Sling */
 requestProcessor.processRequest(req, resp, request.getResourceResolver());
 String html = resp.getContent();
 

Getting the HTML markup for a resource in AEM.

@SlingServlet(paths="/bin/foo")
public class AemResourceResolutionServlet extends SlingSafeMethodsServlet 

 /** Service to create HTTP Servlet requests and responses */
 @Reference
 private RequestResponseFactory requestResponseFactory;

 /** Service to process requests through Sling */
 @Reference
 private SlingRequestProcessor requestProcessor;

 @Override
 protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException 

 /* The resource path to resolve. Use any selectors or extension. */
 String requestPath = "/content/myapp/us/en/index/jcr:content/myparsys/mycomponent_f93d.html";

 /* Setup request */
 HttpServletRequest req = requestResponseFactory.createRequest("GET", requestPath);
 WCMMode.DISABLED.toRequest(req);

 /* Setup response */
 ByteArrayOutputStream out = new ByteArrayOutputStream();
 HttpServletResponse resp = requestResponseFactory.createResponse(out);

 /* Process request through Sling */
 requestProcessor.processRequest(req, resp, request.getResourceResolver());
 String html = out.toString();
