AbstractXmlFlowExecutionTests for inherited flow

[nstoddar]

Is it currently possible to write a unit test for an inherited flow? I'm created a very simple sample one, but it doesn't appear that there's a way to create the correct FlowDefinitionResources in getResource().

    @Override
    protected FlowDefinitionResource getResource(FlowDefinitionResourceFactory factory) {
        return factory.createClassPathResource("/com/sample/a.xml, /com/sample/b.xml", getClass());
    }

.. is invalid.

while only including the inherited flow causes

As I see it, we should have something like

    protected FlowDefinitionResource[] getResources(FlowDefinitionResourceFactory factory) {
        return new FlowDefinitionResource[] {
                factory.createClassPathResource("/com/sample/a.xml", getClass()),
                factory.createClassPathResource("/com/sample/b.xml", getClass())
        };
    }

Am I correct on this one, or just way off base?
