These failures look like we should add a proper API to oslo.messaging to<br>
set the notification and rpc backends for testing. The configuration<br>
options are *not* part of the API of the library.<br>
<br>
There is already an oslo_messaging.conffixture module with a fixture<br>
class, but it looks like it defaults to rabbit. Maybe someone wants to<br>
propose a patch to make that a parameter to the constructor?<br>

<br>
These failures should be fixed by releasing the patch that Mehdi<br>
provided that ensures there is a valid default transport configured.<br>

Lance has already described these as mocking implementation details of<br>
the library. I expect we'll need someone with keystone experience to<br>
work out what the best solution is to do there.<br></blockquote><div><br></div><div>So - I think it's apparent there are two things to do to fix this for keystone, which could be true for other projects as well.<div><br></div><div>To recap, keystone has tests to assert the plumbing to send a notification was called, or not called, depending on configuration options in keystone (we allow operators to opt out of noisy notifications, like authenticate).</div><div><br></div><div>As noted earlier, we shouldn't be making these assertions using an internal method of oslo.messaging. I have a patch up to refactor that to use the public API instead [0]. Even with that fix [0], the tests mentioned by Matt still fail because there isn't a sane default. I have a separate patch up to make keystone's tests work by supplying the default introduced in version 9.0.1 [1], overriding the configuration option for transport_url. This got a bit hairy in a circular-dependency kind of way because get_notification_transport() [2] is what registers the default options, which is broken. I have a patch to keystone [3] showing how I worked around this, which might not be needed if we allow the constructor to accept an override for transport_url.</div><div><br></div><div>[0] <a href="https://review.openstack.org/#/c/609072/">https://review.openstack.org/#/c/609072/</a></div><div>[1] <a href="https://review.openstack.org/#/c/608196/3/oslo_messaging/transport.py">https://review.openstack.org/#/c/608196/3/oslo_messaging/transport.py</a></div><div>[2] <a href="https://git.openstack.org/cgit/openstack/oslo.messaging/tree/oslo_messaging/notify/notifier.py#n167">https://git.openstack.org/cgit/openstack/oslo.messaging/tree/oslo_messaging/notify/notifier.py#n167</a></div><div>[3] <a href="https://review.openstack.org/#/c/609106/">https://review.openstack.org/#/c/609106/</a></div></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
