Arquillian - How to debug managed Wildfly container - testing

Question

I am using Arquillian to write black box tests for my RESTful application. I am actually capable of debug the test classes, but unable to debug my application classes. I would like to know exactly how to do that.
My arquillian.xml:
<arquillian xmlns="http://jboss.org/schema/arquillian"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://jboss.org/schema/arquillian
http://jboss.org/schema/arquillian/arquillian_1_0.xsd">
<container qualifier="jbossas-managed" default="true">
<configuration>
<property name="jbossHome">D:\desenv\arquivos\servidores\wildfly-9.0.1.Final-test</property>
<property name="allowConnectingToRunningServer">true</property>
<property name="javaVmArguments">-Dorg.apache.deltaspike.ProjectStage=IntegrationTest</property>
</configuration>
</container>
One of my test classes:
#RunAsClient
#RunWith(Arquillian.class)
public class AuthenticationBlackBoxTest extends AbstractBlackBoxTest {
#Test
public void testInvalidCredentials(#ArquillianResource URL baseURI) {
Client client = ClientBuilder.newClient();
WebTarget target = client.target(baseURI.toString()).path("api/v1/auth");
Response response = target.request(MediaType.APPLICATION_JSON)
.post(Entity.entity(new Credentials("invalid", "invalid"), MediaType.APPLICATION_JSON));
Assert.assertEquals(401, response.getStatus());
response.close();
client.close();
}
#Test
public void testValidCredentials(#ArquillianResource URL baseURI) {
Client client = ClientBuilder.newClient();
WebTarget target = client.target(baseURI.toString()).path("api/v1/auth");
Entity<Credentials> credentialsEntity = Entity.entity(new Credentials("adm#adm.com", "123"), MediaType.APPLICATION_JSON);
Response response = target.request(MediaType.APPLICATION_JSON)
.post(credentialsEntity);
Assert.assertEquals(200, response.getStatus());
response.close();
client.close();
}
}

Inside arquillian.xml for javaVmArguments element add -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=y.
Then in your favourite IDE you have to define a new Remote Debug configuration where you specify the host(localhost), port(8787). Place your break point, then run your test and finally start the remote debug. Official doc here.
