Hi, Now Nova and Ironic have implemented API microversions in Kilo. Nova's microversions are v2.1 - v2.3. Ironic's microversions are v1.1 - v1.6.
Now Tempest is testing the lowest microversion on the gate, and Ironic's microversions test patch[1] is on the gerrit. Before merging the patch, I'd like to propose consistent test way for microversions of Nova and Ironic. My suggestion is the test target microversions are: * the lowest microversion * the biggest microversion, but don't use the keyword "latest" on a header and these microversions tests are operated on different gate jobs. The lowest microversion is already tested on check-tempest-dsvm-full or something, so this proposes just to add the biggest microversion job like check-tempest-dsvm-full-big-microversion. [background] In long-term, these microversions continue increasing and it is difficult to run Tempest for all microversions on the gate because of test workload. So I feel we need to select microversions which are tested on the gate for efficient testing. [the lowest microversion] On microversion mechanism, if a client *doesn't* specify favorite microversion in its request header, a Nova/Ironic server considers the request as the lowest microversion. So the lowest microversion is default behavior and important. I think we need to test it at least. [the biggest microversion] On microversion mechanism, if a client specify the keyword "latest" in its request header instead of microversion, a Nova/Ironic server works on the biggest microversion behavior. During the development, there is time lag between each project dev and Tempest dev. After adding a new API on a project, corresponding tests are added to Tempest in most cases. So if specifying the keyword "latest", Tempest would not handle the request/response and fail, because Tempest can not catch the latest API changes until corresponding Tempest patch is merged. So it is necessary to have the target microversion config option in Tempest and pass specific biggest microversion to Tempest with openstack-infra/project-config. Any thoughts?
