tl;dr; Please be advised that the Neutron unit test tree is undergoing reorganization, and if you depend on any of the test modules being renamed or restructured, you will need to update your unit tests to avoid breakage. The wiki has been updated accordingly: https://wiki.openstack.org/wiki/Neutron/LibraryAPIBreakage#Breakages Long version: We’re in the process of landing a number of patches intended to reorganize the neutron unit test tree: https://review.openstack.org/#/c/170329/ https://review.openstack.org/#/c/158811/ https://review.openstack.org/#/c/171004/ https://review.openstack.org/#/c/171005/ This effort was intended to land as close to RC as possible to avoid conflicting with in-flight patches and minimize the pain of backporting fixes. Thanks, Maru
