refstack-client is a command line utility that allows you to execute Tempest
test runs based on configurations you specify. When finished running Tempest
it can send the passed test data to a RefStack API server.
We’ve created an “easy button” for Ubuntu, Centos, RHEL and openSUSE.
Make sure you have
Get the refstack client:
git clone https://opendev.org/openinfra/refstack-client.git
Go into the
Run the “easy button” setup:
a. -c option allows to specify SHA of commit or branch in Tempest repository which will be installed.
b. -t option allows to specify tag in Tempest repository which will be installed. For example: execute
./setup_env -t tags/3to install Tempest tag-3. By default, Tempest 31.1.0 will be installed from commit 56d259dd78cc9ae974cc5dc24a54dbd8008770e6 (June 2022).
c. -p option allows to specify python version - python 2.7 (-p 2), 3.8.10 (-p 3) or any specific one by -p X.X.X. Default to python 3.8.10.
d. -q option makes
refstack-clientrun quitely - if
refstack-clientis considered as installed.
e. -s option makes
python-tempestconffrom the given source (path) - used when running f.e. in Zuul.
Prepare a tempest configuration file (or let
refstack-clientgenerate it for you, see step #4) that is customized to your cloud environment. Samples of minimal Tempest configurations are provided in the
accounts.yaml.sample. Note that these samples will likely need changes or additional information to work with your cloud.
Note: Use Tempest Pre-Provisioned credentials to provide user test accounts.
Go into the
Source to use the correct Python environment:
(optional) Generate tempest.conf using
refstack-client config --use-test-accounts <path to account file>
The above command will create the tempest.conf in etc folder.
Note: If account file is not available, then: * Source the keystonerc file containing cloud credentials and run:
refstack-client config It will create accounts.yaml and temepst.conf file in `etc` folder.
Validate your setup by running a short test:
refstack-client test \ -c <Path of the tempest configuration file to use> -v -- \ --regex tempest.api.identity.v3.test_tokens.TokensV3Test.test_create_token
To run the entire API test set:
refstack-client test -c <Path of the tempest configuration file to use> -v
To run only those tests specified in an OpenStack Powered (TM) Guideline:
refstack-client test -c <Path of the tempest configuration file to use> -v --test-list <Absolute path of test list>
refstack-client test \ -c ~/tempest.conf -v \ --test-list "https://refstack.openstack.org/api/v1/guidelines/2020.11/tests?target=platform&type=required&alias=true&flag=false"
This will run only the test cases required by the 2020.11 guidelines under Platform OpenStack Marketing Program that have not been flagged. More about the marketing programs at Interop and OpenStack Marketing Programs.
For example tests under the compute program are available: https://refstack.openstack.org/api/v1/guidelines/2020.11/tests?target=compute&type=required&alias=true&flag=false Tests of add-on programs can be found similarly, f.e. tests under dns program: https://refstack.openstack.org/api/v1/guidelines/dns.2020.11/tests?target=dns&type=required&alias=true&flag=false or tests under orchestration program: https://refstack.openstack.org/api/v1/guidelines/orchestration.2020.11/tests?target=orchestration&type=required&alias=true&flag=false
-voption will show the Tempest test result output.
--uploadoption will have your test results be uploaded to the default RefStack API server or the server specified by
--test-listoption will allow you to specify the file path or URL of a test list text file. This test list should contain specific test cases that should be tested. Tests lists passed in using this argument will be normalized with the current Tempest environment to eliminate any attribute mismatches.
--urloption will allow you to change where test results should be uploaded.
-roption with a string will prefix the JSON result file with the given string (e.g.
-r my-testwill yield a result file like ‘my-test-0.json’).
--enables you to pass arbitrary arguments to tempest run. After the first
--, all other subsequent arguments will be passed to tempest run as is. This is mainly used for quick verification of the target test cases. (e.g.
-- --regex tempest.api.identity.v2.test_token)
If you have provisioned multiple user/project accounts you can run parallel test execution by enabling the
refstack-client test --helpfor the full list of arguments.
Upload your results.
If you previously ran a test with
--uploadoption, you can later upload your results to a RefStack API server with your digital signature. By default, the results are private and you can decide to share or delete the results later.
Following is the command to upload your result:
refstack-client upload <Path of results file> -i <path-to-private-key>
The results file is a JSON file generated by
refstack-clientwhen a test has completed. This is saved in .tempest/.stestr. When you use the
uploadcommand, you can also override the RefStack API server uploaded to with the
Alternatively, you can use the
upload-subunitcommand to upload results using an existing subunit file. This requires that you pass in the Keystone endpoint URL for the cloud that was tested to generate the subunit data:
refstack-client upload-subunit \ --keystone-endpoint http://some.url:5000/v3 <Path of subunit file> \ -i <path-to-private-key>
Intructions for uploading data with signature can be found at https://opendev.org/openinfra/refstack/src/branch/master/doc/source/uploading_private_results.rst
View uploaded test set.
You can list previously uploaded data from a RefStack API server by using the following command:
refstack-client list --url <URL of the RefStack API server> -i <path to private key>
Alternatively, if you uploaded the results to the official RefStack server you can view them by using RefStack page where all uploaded results associated with the particular account (the account private key used to upload the results belongs to) will be shown and may be further managed.

Interop and OpenStack Marketing Programs¶
We have created an ansible role called ansible-role-refstack-client in order
to simplify and automate running of
refstack-client. The role can be easily
integrated to an automation machinery - f.e. we use the role for running
refstack-client on a devstack environment in Zuul where we run tests of
every OpenStack Marketing Program of the current guideline. The latest builds
can be found here__.
See the CONTRIBUTING guide on how to get involved.
