Maven problem while trying to work on aem Junit testing

[Former Community Member]

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:

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

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>

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

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?
