Step 9. Verifying cloud via Tempest verifier

As you may know, Rally has a verification component (aka ‘rally verify’). Earlier the purpose of this component was to simplify work with Tempest framework (The OpenStack Integration Test Suite). Rally provided a quite simple interface to install and configure Tempest, run tests and build a report with results. But now the verification component allows us to simplify work not only with Tempest but also with any test frameworks or tools. All you need is to create a plugin for your framework or tool, and you will be able to use ‘rally verify’ interface for it. At this point, Rally supports only one plugin in the verification component out of the box - as you might guess, Tempest plugin. In this guide, we will show how to use Tempest and Rally together via the updated ‘rally verify’ interface. We assume that you already have a Rally installation and have already registered an OpenStack deployment in Rally. So, let’s get started!

Create/delete Tempest verifier

Execute the following command to create a Tempest verifier:

$ rally verify create-verifier --type tempest --name tempest-verifier
2017-01-18 14:43:20.807 5125 INFO rally.api [-] Creating verifier 'tempest-verifier'.

Using verifier 'tempest-verifier' (UUID=cde1b03d-d1eb-47f2-a997-3fd21b1d8810) as the default verifier for the future operations.

The command clones Tempest from the https://git.openstack.org/openstack/tempest repository and installs it in a Python virtual environment for the current deployment by default. All information about the created verifier is stored in a database. It allows us to set up different Tempest versions and easily switch between them. How to do it will be described bellow. You can list all installed verifiers via the rally verify list-verifiers command.

The arguments below allow us to override the default behavior.

Use the –source argument to specify an alternate git repository location. The path to a local Tempest repository or a URL of a remote repository are both valid values.

$ rally verify create-verifier --type tempest --name tempest-verifier --source /home/ubuntu/tempest/

Use the –system-wide argument to perform system-wide Tempest installation. In this case, the virtual environment will not be created and Tempest requirements will not be installed. Moreover, it is assumed that requirements are already present in the local environment. This argument is useful when users don’t have an Internet connection to install requirements, but they have pre-installed ones in the local environment.

Available suites for Tempest 14.0.0 (the latest Tempest release when this documentation was written) are full, smoke, compute, identity, image, network, object_storage, orchestration, volume, scenario. The number of available suites depends on Tempest version because some test sets move from the Tempest tree to the corresponding Tempest plugins.

Moreover, users can run a certain set of tests, using a regular expression.
