A while ago we copied Tempest networking API tests in to the
Neutron repo, and along came thousands of lines of code of Tempest
testing infrastructure (neutron.tests.tempest). For a while we
periodically refreshed our fork via:
tools/copy_api_tests_from_tempest.sh
I think it's time we move away from that model by eliminating
the fork. We do this by deleting unused code and importing the
rest from tempest_lib. There's some Tempest code still not
moved from Tempest to tempest_lib in tempest.common. I think
it's preferable to import that code than to copy it, and Tempest
cores mostly agree. Manila and Ironic also do the same.
To be able to import from tempest I added it as a requirement:
Since Tempest is not on PyPi, I had to get it from git. Only the api
tests environment needs Tempest, so instead of adding it to
test-requirements, I added it specifically to the api and
api-constraints venvs.
neutron.tests.tempest.test and neutron.tests.tempest.common.*
still remain. These are tighly coupled with one another, and
sadly since Neutron forked Tempest code, Tempest has made significant
changes to those files that also require changes to the test files.
I aim to get rid of the Neutron fork of these files in a follow up
change.
Also fixed import grouping in test files so that it's std libs,
3rd party libs, and then Neutron code.
* Removed neutron.tests.tempest.config:
- We only added one option after the fork. I created a new group
called 'neutron_plugin_options' and moved the new option to that
group. This is in preperation for the Tempest plugin architecture,
where you're supposed to add new config options to a new group
and not to existing configuration groups. Note that this is
obviously a backward incompatible change, but it's to an option
added in the same cycle.
* Removed neutron.tests.tempest.test and neutron.tests.tempest.common.
- This introduced an API change to the way we access Keystone,
which required mechanical changes to a few tests (create_tenant
calls need a different client now).
- The way Tempest manages primary, admin and alternative tenant
credentials was changed after we forked, which required another
mechanical change to a few tests.
* Cut all of the Keystone clients we don't need. We only need
to create/delete tenants, the other clients were used in Tempest by
actual Keystone tests.
* Changed neutron.tests.api.base.BaseNetworkTest:
- Re-implemented get_client_manager so that it returns the Neutron
clients manager and not the one in the Tempest repo.
- Updated it from the Tempest repo so that it uses the new way
to manage credentials (Since it now uses the Tempest test base
class and not our out of date forked copy).
