Red Hat SummitChapter 4. Cleaning Integration Test Suite (tempest) resources
Before you validate your deployments by using OpenStack Integration Test Suite (tempest), run the cleanup command with the --init-saved-state flag. This command scans your environment to discover resources, for example networks, volumes, images, flavors, projects, and users. The discovered resources are saved in a file called saved_state.json. When the tempest cleanup command is executed all resources not recorded in the saved_state.json file are deleted.
Prerequisites
- An OpenStack environment that contains the Integration Test Suite packages. For more information, see Installing the Integration Test Suite with director.
- An Integration Test Suite configuration that corresponds to your OpenStack environment. For more information, see Creating a workspace.
- One or more completed Integration Test Suite validation tests.
4.1. Performing a dry run
Perform a dry run before you execute the cleanup. A dry run lists the files that Integration Test Suite would delete by a cleanup, without actually deleting any files. The dry_run.json file contains the list of files that a cleanup deletes.
Procedure
Complete the dry run:
# tempest cleanup --dry-run
-
Review the
dry_run.jsonfile to ensure that the cleanup does not delete any files that you require for your environment.
4.2. Performing a tempest clean up
Before you run any tempest tests, you must initialize the saved state. This creates the file saved_state.json, which prevents the cleanup from deleting objects that must be kept.
If you do not run the cleanup command with the --init-saved-state flag, RHOSP objects are deleted.
If you create objects after running the cleanup command with --init-saved-state, those objects can be deleted by subsequent tempest commands.
Procedure
Initialize the saved state to create the
saved_state.jsonfile:# tempest cleanup --init-saved-state
Perform the cleanup:
# tempest cleanup
The tempest cleanup command deletes tempest resources but does not delete projects or the tempest administrator account.
You can modify the saved_state.json file to include or exclude objects that you want to retain or remove.
