Re: [jboss-as7-dev] Clustering tests
I've answered as best I can without having looked too much into it.

Hi Kabir,
Thanks for the tough. Yes that is true and surely does contribute to the
slowness.
The reason for the lots of stopping is because we need to use manual
containers (for simulating failover, state transfer, undeploy,
singleton, etc). The containers are set to manual mode and unmanaged
deployments.
Understood :-)
Unfortunately, this currently means that the containers are stopped
after *each* test class and then started again. ARQ does this. We would
also need to be able to order the test class executions. Most of these
cases (currently all) the running container could be re-used (even
though we shut it down in the middle of the test).
For this we would probably need support in Arquillian. (class order +
dont turn off container after class?) Aslak, WDYT?

How would this actually work? Use auto containers and use stop and start
to simulate up and down without having to do any fix in ARQ? Hmhm, thats
interesting.
I think changing ManagedDeployableContainer in the as source tree might work, or
alternatively creating another container for clustering. I'll just keep calling it
ManagedDeployableContainer for now :-) ManagedDeployableContainer is where the start/stop
calls seem to end up. Some tracking of if it is currently started/stopped could be added
to know whether to start it for real (on first start) or reloading out of admin-only. A
problem is when to do the real stop, rather than the reload->admin-only, e.g. at the
end of the suite but there might be some hooks that can be used? I guess it really depends
on if the ManagedDeployableContainer instances behind the ContainerController are the same
for each test or not.
I've not really looked at it enough to know about the ordering stuff you mention.
This would however prohibit use of stop by kill or custom "kill" and
probably use of different container confs as well.
Kill probably should kill the
process, and be tracked in the ManagedDeployableContainer so that the next start() does a
real start
However, this seems to me too much of a workaround (for instance the
server's JVM never shuts down).
