[jboss-dev-forums] [Design of JCA on JBoss] - Mock JMS Provider

[weston.price@jboss.com]

I am nearing completion on the first 'rough' pass of a MockJMS framework that allows exercising the JMS/JCA adapter outside of the application server.  The fundamentals are working and I can send messages, test DLQ handling and simulate provider failures without having to deploy anything to the application server.  While this is not end to end testing, I believe it does provide a decent framework for excercising the fundamental purposes of the inflow adapter:

Provider connectivity
SeverSession/Pool management
before/onMessage/after delivery semantics
Correct tranasaction enlistment based on transacted/non-transacted delivery 

While most of the code is stubbed out, the necessary functions to get a basic working model are implemented. The trickiest part was extending JmsActivation and the DLQQueueHandler to override looking up the administrative objects from a real JNDI tree rather than simple instantiation. 

This is not a mechanism to test JMS provider functionality. We have that pretty well covered in the rest of the testsuite.
