I think you have the right idea. Build a standalone web-service
client. In your example you're using a SOAP service, so I would use
XML::Compile::SOAP and XML::Compile::WSDL11, but you might have good
luck with the SOAP::* modules, I am less familiar with those. Either
way, build a standalone client which you can test on its own. Finally
build a thin Catalyst-aware shim, using Catalyst::Model::Adaptor or
Catalyst::Component::InstancePerContext, which wraps/consumes your
standalone model and captures whatever Catalyst config etc you need to
use your model within Catalyst. This approach may require slightly
more code files than the monolithic approach but will be much simpler
to test since you remove the Catalyst dependency from verifying the
majority of your model's behaviour.
