The configuration options registered by oslo.messaging should not be directly relied upon by users of the library, since those config option names could change in future. Add an API which allows API users to override specific configuration options e.g. self.messaging_conf = self.useFixture(messaging.ConfFixture(cfg.CONF)) self.messaging_conf.transport_driver = 'fake' Change-Id: If0d837e1b86e3b04237fde522551cfb81505a543
