Hi,

I am trying to write Junit test cases and also use mockito for the same. My system set up is:

Windows 64bit desktop,16 GB RAM

I am using AEM 6.3, eclipse Luna,Java 1.8.0_73,Maven 3.5.0

I have wrriten a Junit test case for aem code which requires mocking a session to go ahead, i added few dependencies in my pom.xml like

<dependency>

    <groupId>org.apache.sling</groupId>

    <artifactId>org.apache.sling.testing.jcr-mock</artifactId>

    <version>1.1.14</version>

</dependency>

for mocking.

After i build the project i am getting the below error in the pom.xml file.Please find the stack trace as:

C:\Data\BTproject\AEM\CMS\aem-presales\tags\release_1.0\core\src\main\java\com\bt\aem\presales\component

\LocalNavigationSelectionUse.java : Unable to load compiled class:

Did you build your project using Maven Archetype 11. If no - do that and you will get all of the dependencies that you need to build the project.

You will get this sample code

Hi Mac,

Thanks for the reply. I built the project using archetype 11 and a folder got created as shown below.

But the code for which i have to write Junit is in the below project code under "aem-presales.core" in which the pom.xml shows some error as i have already posted.

The error log does not say that there are dependencies missing,but says some sort of "

org.apache.felix:maven-scr-plugin:1.20.0:scr:generate-scr-

scrdescriptor:process-classes". So do you think its a build issue or something else?

Please suggest how i should go about this?

Hi Mac,

Thanks for the reply.The code structure is already there and i am trying to write only Junits for a service class.When i started writing the Junit, there is a method call which takes session as a parameter. So i learnt that i need to mock the session in order to go ahead.So i started adding dependencies in the pom.xml. I encountered the above error, and i am trying to resolve it, but it still persists.What can i do next? please suggest.

Thanks,

Anjan

Hi,


Can you try with the below entries as dependencies in your pom.xml and see if it helps.

<dependency>

            <groupId>org.mockito</groupId>

            <artifactId>mockito-all</artifactId>

            <version>1.10.19</version>

        </dependency>

<dependency>

            <groupId>org.jmockit</groupId>

            <artifactId>jmockit</artifactId>

        </dependency>

YOu can see examples under the test package when you create a Maven Archetype 11 project -- see Creating an Adobe Experience Manager 6.3 Project using Adobe Maven Archetype 11
