[jboss-dev] Testing Deployers Outside AS

[Andrew Lee Rubinger]

I haven't made too much noise about this yet, but now that it's released:

The Arquillian testing framework, as of 1.0.0.Alpha2, has a backing 
container integration for JBoss Reloaded.  Carlo's originally defined 
"Reloaded" as the component which brings together a minimally-running 
Virutal Deployment Framework, MC, and jboss-bootstrap:

http://community.jboss.org/docs/DOC-13453

The take-home that our Arquillian adaptor provides is an ultra-slim way 
to bring up MC/VDF without any explicit coding and enables testing of 
bits like Deployers and other MC beans in a slim manner, outside of AS.

For instance, I check the postcondition that one of my deployers adds an 
attachment to the DeploymentUnit:

http://anonsvn.jboss.org/repos/jbossas/projects/ejb3/components/async/trunk/deployer/src/test/java/org/jboss/ejb3/async/deployer/AsyncExecutorServiceDeployerTestCase.java

In this way we can precertify that our projects' VDF components are 
working before they hit AS.  The test above runs in under 2s.

I recommend to projects using VDF that we start to use Arquillian as 
outlined above.  This is also possible via manual setup, but the 
Reloaded APIs are still under change/flux, and hiding behind Arquillian 
to do the wiring gives you a much smaller API to manage (not to mention 
that it saves you from setting up jboss-bootstrap/MC on your own).
