Comment 10 for bug 1726357

The config file is not used for each individual test case it's loaded once for the entire test suite at the beginning of the run. (it's techincally one load per worker, which occurs at the first get attr on tempest.conf.CONF) The config file is not expected to change at all during the run and the values are only loaded once. From the perspective of a running tempest test the config file is static. An ipc or shared memory mechanism between tests wouldn't provide any benefits because the tests cases are supposed to be isolated from each other during run time. (to provide proper test repeatability) What exactly are you trying to solve?

Either way I'm not sure how this relates to this bug? (which was specifically about the passed in config file being ignored) It sounds like you want to write a new feature for tempest. If so I'd suggest writing a spec to discuss what you think we should add in detail. I've never heard of anyone looking at that before.
