So lets explore this a bit using the testcase below as an example of
what we might want to do. It uses the tests setup and tearDown methods
to createand stop a Tuscany Node and then the in a test method uses an
SCAClient to get a service so that would need someway to find the
already created Node.
Some things are:
- the Tuscany Node doesn't have a domain URI so there isn't any way to
create or match existing Nodes to match the URI passed in on the
SCAClient getService call.
- there's no link between the Node and SCAClient instances for the
SCAClient to find the Node so it will probably have to use some static
in the factories
- we probably want to think about supporting multiple Nodes in a
domain so i'm wondering if we need to have an SCADomain again and have
the SCADomain know about multiple Nodes.
Comments?
