Chapter 1. OpenStack Integration Test Suite (tempest) validations
Because Red Hat OpenStack Platform (RHOSP) consists of many different projects, it is important to test the interoperability of the projects within your RHOSP cluster. The OpenStack Integration Test Suite automates the integration testing of your RHOSP deployment. You can run tests to ensure that your cluster works as expected. Test output to provide early warning of potential problems, especially after an upgrade.
The Integration Test Suite contains tests for OpenStack API validation and scenario testing, as well as unit testing for self-validation. The Integration Test Suite performs black box testing by using the OpenStack public APIs, with tempest as the test runner.
The OpenStack Integration Test Suite (tempest) acts as a gate for commits to the Red Hat OpenStack Platform (RHOSP) core projects, it can stress test to generate load on a cloud deployment, and it can perform CLI tests to check the response formatting of the command line. You can run scenario tests and API tests against your RHOSP cloud deployment.
Scenario tests
Scenario tests simulate a typical end user action workflow to test the integration points between services. The testing framework conducts the configuration, tests the integration between services, and is then removed automatically. Tag the tests with the services that they relate to clarify, which client libraries the test uses.
The following scenarios are based on a use case:
- Uploading an image to the Image Service
- Deploying an instance from the image
- Attaching a volume to the instance
- Creating a snapshot of the instance
- Detaching the volume from the instance
API tests
API tests validate the OpenStack API. Tests use the OpenStack Integration Test Suite implementation of the OpenStack API. You can use both valid and invalid JSON to ensure that error responses are valid. You can run tests independently and you do not have to rely on the previous test state.
