RefStack Client

Overview

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.

Environment setup

We've created an "easy button" for Ubuntu, Centos, RHEL and openSUSE.

  1. Make sure you have git installed
  2. Get the refstack client: git clone https://opendev.org/osf/refstack-client.git
  3. Go into the refstack-client directory: cd refstack-client
  4. Run the "easy button" setup: ./setup_env

    Options:

    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/3 to install Tempest tag-3. By default, Tempest will be installed from commit e64c78dcf7 (Oct, 2019).

    c. -p option allows to specify python version - python 2.7 (-p 2), 3.6 (-p 3) or any specific one by -p X.X.X. Default to python 3.6.

    d. -q option makes refstack-client run quitely - if .tempest directory exists refstack-client is considered as installed.

    e. -s option makes refstack-client use python-tempestconf from the given source (path) - used when running f.e. in Zuul.

Usage

  1. Prepare a tempest configuration file (or let refstack-client generate it for you, see step #4) that is customized to your cloud environment. Samples of minimal Tempest configurations are provided in the etc directory in tempest.conf.sample and 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.

  2. Go into the refstack-client directory:

    cd ~/refstack-client
  3. Source to use the correct Python environment:

    source .venv/bin/activate
  4. (optional) Generate tempest.conf using refstack-client:

    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.

  5. 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
  6. Run tests.

    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>

    For example:

    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

    Note:

    1. Adding the -v option will show the Tempest test result output.
    2. Adding the --upload option will have your test results be uploaded to the default RefStack API server or the server specified by --url.
    3. Adding the --test-list option 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.
    4. Adding the --url option will allow you to change where test results should be uploaded.
    5. Adding the -r option with a string will prefix the JSON result file with the given string (e.g. -r my-test will yield a result file like 'my-test-0.json').
    6. Adding -- 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)
    7. If you have provisioned multiple user/project accounts you can run parallel test execution by enabling the --parallel flag.

    Use refstack-client test --help for the full list of arguments.

  7. Upload your results.

    If you previously ran a test with refstack-client without the --upload option, 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-client when a test has completed. This is saved in .tempest/.stestr. When you use the upload command, you can also override the RefStack API server uploaded to with the --url option.

    Alternatively, you can use the upload-subunit command 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/osf/refstack/src/branch/master/doc/source/uploading_private_results.rst

  8. 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.

Tempest hacking

By default, refstack-client installs Tempest into the .tempest directory. If you're interested in working with Tempest directly for debugging or configuration, you can activate a working Tempest environment by switching to that directory and using the installed dependencies.

  1. cd .tempest
  2. source ./.venv/bin/activate and run tests manually with tempest run.

This will make the entire Tempest environment available for you to run, including tempest run. More about Tempest can be found at its documentation.

Interop and OpenStack Marketing Programs

The tests refstack-client runs are defined within interop repository and divided into several OpenStack Marketing Programs, the list of the programs can be found at RefStack page.

ansible-role-refstack-client

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.
