You'll need to play with the task service stub, specifically, setting
the location of the queue.yaml file in your local development
environment. Something like:
taskqueue_stub = apiproxy_stub_map.apiproxy.GetStub( 'taskqueue' )
taskqueue_stub._root_path = os.path.join( os.path.dirname( __file__ ),
'..' )
in setUp should suffice.
