Debugging Using Wildfly and Arquillian

This should be most useful for those starting out with Arquillian! I spent quite some time before finding out the solution.


The arquillian.xmlshould include the following contents:

 <engine>  
     <property name="deploymentExportPath">target/</property>  
   </engine>  
   <container qualifier="jbossas-managed-wildfly-8" default="true">  
        <protocol type="jmx-as7">  
       <property name="executionType">REMOTE</property>  
     </protocol>  
     <configuration>  
          <property name="allowConnectingToRunningServer">true</property>  
       <property name="jbossHome">C:\Program Files (x86)\PSL\RCA\ApplicationServer</property>  
       <property name="modulePath">C:\Program Files (x86)\PSL\RCA\ApplicationServer\modules</property>  
       <property name="javaVmArguments">-Xrunjdwp=transport=dt_socket,address=8000,server=y,suspend=n -Djava.util.logging.manager=org.jboss.logmanager.LogManager</property>  
     </configuration>  
   </container>  



Include the following profile in your Maven pom.xml:

  <profile>  
   <id>arquillian-wildfly-managed</id>  
   <activation>  
        <activeByDefault>true</activeByDefault>  
        </activation>    
   <dependencies>  
      <dependency>  
        <groupId>org.jboss.spec</groupId>  
        <artifactId>jboss-javaee-6.0</artifactId>  
        <version>3.0.1.Final</version>  
        <type>pom</type>  
        <scope>test</scope>  
      </dependency>  
      <!-- Required by jboss-javaee-6.0:3.0.2.Final (https://issues.jboss.org/browse/JBBUILD-708) -->  
      <dependency>  
        <groupId>xalan</groupId>  
        <artifactId>xalan</artifactId>  
        <version>2.7.1</version>  
        <scope>test</scope>  
      </dependency>  
      <dependency>  
        <groupId>org.wildfly</groupId>  
        <artifactId>wildfly-arquillian-container-managed</artifactId>  
        <version>8.1.0.Final</version>  
        <scope>test</scope>  
      </dependency>  
      </dependencies>  
   </profile>  

When we use Arquillian, there are three VM's that are involved:


1. Arquillian (Source) > Remote/Managed Server


Start the Remote/Managed Server with the following line added to standalone.conf.bat

 set "JAVA_OPTS=%JAVA_OPTS% -agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n"  

In Eclipse, Right Click on your project and Click on "Debug" and under "Connect" - Select your "Host" and "Port". Click on "Apply" and "Debug". This will connect the Debugger to the Remote VM inside Wildfly. 


2. Test > Remote/Managed Server


Now, Right Click on your Arquillian Test and Click on "Debug As.." or "Debug Configurations". Then select either "TestNG" or "JUnit".

 

Now, you will be able to hit the breakpoint. Happy Debugging!
