Running Spec2 Unit test case from eclipse

By
In this article I’ll give some quick hints about how you can run your Scala unit test cases written using Spec2 from eclipse.

Writing unit test cases is fun and important aspect of any application where quality is important and large groups/teams are working on different parts of application.

You may want to run unit test cases directly from editor where you are writing test cases. Almost every other editor support execution of Java Junit test cases from eclipse.

When you are working with Scala code based you may want to write unit test cases using Spec2 and want to run directly from eclipse. As such you cannot do with making additional changes to test cases; here are the changes that you’ll have to add to your test cases so that you can run them from eclipse:

1)    Add below import statements to you Unit test class
import org.junit.runner.RunWith
import org.specs2.runner.{JUnitRunner}

2)    Annotate your test class with following annotation:
@RunWith(classOf[JUnitRunner])

Now if you right click on your test case class you should see an option to execute your test case (Right click on test class -> Run As -> Scala Unit Test)

Hope this’ll help you to save some time while writing test cases.

AEM, FORM Submission & Handling POST requests

By
In this article I’ll be specifically talking about how to handle POST request in AEM and what options we have. Please note that Adobe has added more security around handling POST request from AEM 6.x onwards to prevent CSRF attack. If you don’t configure AEM correctly, POST requests will not work even after using any of methods explained in this article.   You can read more about security configurations and restriction at: https://docs.adobe.com/docs/en/aem/6-1/develop/security/csrf-protection.html It is very common use cases to have external application POST some data to an AEM page (e.g. /content/en/home.html) or even submit a form (POST) to same URL. But, as you know that in AEM POST works differently and any POST call to AEM is intercepted by Sling’s POST servlet (org.apache.sling.servlets.post.impl.SlingPostServlet). In some cases org.apache.sling.servlets.post.impl. SlingPostServlet is very useful when you actually want to perform CURD (create, update, read a...

AEM - Query list of components and templates

By
Some time while migration or for auditing purposes we need to know where a particular component/template or any other resource have been used. Have you ever wondered about how to fetch a list of all the paths where a particular component or template is being used? I this short article I am going to show a quick way to write a utility with which you can get list if paths (actual resource nodes) where a targeted resource is being used. Here is the code snipped: public void getResourceListHelper(Resource parentResource , String targetSearchPropertyKey ,  String targetSearchPropertyValue , List components ) {      Resource childResource ; for (Iterator resourceChildrenIter = parentResource .listChildren(); resourceChildrenIter .hasNext();  getResourceListHelper ( childResource, targetSearchPropertyKey, targetSearchPropertyValue, components)) { childResource = (Resource) resourceChildrenIter .next(); ValueMap childProperties = (...

AEM 6.3 - Bundle Whitelisting - Deprecation of administrative authentication

By

I stumbled on an issue when I was using neab with AEM 6.3. I created few neba ResourceModels and when I tried to access neba Model Registry, I got an error ( java.lang.IllegalStateException: org.apache.sling.api.resource.LoginException: Bundle org.eclipse.gemini.blueprint.extender is NOT whitelisted ): Image: neba Model Registry Menu Image: Error Screen NOTE: Neba team has already fixed it on their development branch and we don’t need to explicitly add whitelisting configuration for neba bundle. Here is the reason for error Originally the ResourceResolverFactory.getAdministrativeResourceResolver and SlingRepository.loginAdministrative methods have been defined to provide access to the resource tree and JCR Repository. These methods proved to be inappropriate because they allow for much too broad access. Consequently these methods are being deprecated and will be removed in future releases of the service implementations. The following methods are deprecat...

AEM as a Cloud Service (AEMaaCS) – Architecture Adobe Experience Manager (AEM) is one of the leading CMS from Adobe and is part of Adobe Experience Cloud (AEC). The Adobe Experience Manager (AEM) web content management offers a set of capabilities for creating, managing, delivering, and personalizing content across various digital marketing channels, including web, mobile, and email.  Before we dive into architecture of AEM as a Cloud Service (AEMaaCS) we need to understand why AEMaaCS is needed and how it is different as compared to classic AEM. To understand this, we’ll first look at: Evolution/history of AEM Challenges with traditional/classic AEM (the AEM that majority of us have used from last 10-12 years) Evolution/History of AEM The software was originally launched in early 2000 as Communiqué (CQ) by Day Software of Basel, Switzerland. After CQ 5.3 had been released, Day Software was acquired by Adobe Systems in 2010 then CQ became Adobe Experience Manager. ...
