from google.appengine.api import apiproxy_stub_map from google.appengine.api.files import file_service_stub See This Document <https://cloud.google.com/appengine/docs/standard/python/refdocs/modules/google/appengine/ext/testbed> for more information about how you could register the file service stub.
