It is one example that we need more efforts to decouple unit tests from neutron repo. neutron-vpnaas unit test initializes a router info per router type. Perhaps we need to avoid initializing router info directly in neutron-vpnaas tests, but it will take more time to address it. Short term solution to fix this bug would be to register related L3 opts in neutron-vpnaas code.
