[forge-dev] Again on testing Forge commands

Hey Ivan,

Great observations, definitely things that we want to improve:

Fight the black magic. It shouldn't be so hard to setup a test. What I

Yes, this is an issue. We have a number of ideas for how to improve this,
such as introducing a new @DeployAddon() or @AddonDeployment() annotation,
which is really what our current @AddonDependency() annotation is doing -
deploying an addon. The @AddonDependency() annotation would then deploy AND
establish an addon dependency on the specified coordinate, eliminating the
need to specify .withAddonDependency() in the @Deployment method itself.
Essentially our current situation is one in which we must specify addon
deployment and dependency metadata separately, which leads to quite a bit
of duplicate information (boilerplate.) This should be easy to resolve.
Unfortunately we have a problem with backwards compatability if we change
the existing annotations, so we may need to deprecate them and introduce
entirely new ones in a new package.

I would actually like to solve this problem by refactoring the "Forge Test
Harness" in Furnace and calling it the "Furnace Test Harness" which is
really what it is.

Fight the slow startup time. So, we are using Arquillian. Imagine how would

So one thing to note, is that the slowness here is not the fact that we are
setting up Furnace/Forge from scratch. Just like Wildfly, the runtime
environment is already there, but we still have to deploy our application
(the addons.) There is a great deal of inefficiency, as George says, in the
maven deployment of the addons, and this is (in my opinion) where our
greatest opportunity for improvement lies.

Very open to ideas here. It's been a while since i attached a profiler, but
if nothing has changed, most of the time is spent in maven itself -
resolving dependencies.
