[jboss-as7-dev] Reloading server config from custom file? /// Re: AS config path only as a relative path?

[Ondřej Žižka]

Once talking about testability issues:


The AS 7 testsuite is going to contain many configurations.
Currently we solve that by a combination of:
* multiple Maven modules or Surefire executions
* AS management API to change the config and get it back to original
state.

Both ways are toilsome, complicated, error-prone and hard to maintain.
The estimation is that the number of configurations for EAP final will
be in tens.

Ideal solution for this would be to let Arquillian to reload the server
with a different config file.
It would work the same as restoring config snapshots[1] via mgmt API,
only taking a parameter of which file should be loaded.
So the tests would look like:

@TestCase @ASConfigFile("standalone-foo.xml")
class TestsToBeRunOnFooTestCase { ... }

@TestCase @ASConfigFile("standalone-bar.xml")
class TestsToBeRunOnBarTestCase { ... }

Similar to what is in https://issues.jboss.org/browse/ARQ-746 , only the
server would not need to restart.

Can such feature appear in 7.1.1?


Thanks,
Ondra
