I could see that the Unit tests are run against the latest oslo.messaging from the master, and source tree is old.
http://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt
oslo.messaging===9.2.1

[root@ip9-114-192-185 cinder-es]# grep install_command tox.ini
install_command = pip install -c{env:UPPER_CONSTRAINTS_FILE:https://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt} {opts} {packages}
[root@ip9-114-192-185 cinder-es]#

Will get the configuration fixed. Thanks for the clarification.

Thanks & Regards,

Ahh, here's how it knows :-

$ grep install_command tox.ini
install_command = pip install
-c{env:UPPER_CONSTRAINTS_FILE:https://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt?h=stable/rocky}
