Tobiko

Test Big Cloud Operations

Tobiko is an OpenStack testing framework focusing on areas mostly complementary to Tempest. While tempest main focus has been testing OpenStack rest APIs, the main Tobiko focus is to test OpenStack system operations while "simulating" the use of the cloud as the final user would.

Tobiko's test cases populate the cloud with workloads such as Nova instances; they execute disruption operations such as services/nodes restart; finally they run test cases to validate that the cloud workloads are still functional.

Tobiko's test cases can also be used, for example, for testing that previously created workloads are working right after OpenStack services update/upgrade operation.

Project Requirements

Tobiko Python framework is being automatically tested with below Python versions:

• Python 3.6
• Python 3.7
• Python 3.8

and below Linux distributions:

• CentOS 7 / RHEL 7 (with Python 3.6)
• CentOS 8 / RHEL 8 (with Python 3.6)
• Ubuntu Bionic (with Python 3.6 and 3.7)

Tobiko is also tested for development purposes with below OSes:

• Fedora 31 (with Python 3.7)
• Fedora 32 (with Python 3.8)
• OSX (with Python 3.8)
• Ubuntu Focal (with Python 3.8)

The Tobiko Python framework is being used to implement test cases. As Tobiko can be executed on nodes that are not part of the cloud to test against, this doesn't mean Tobiko requires cloud nodes have to run with one of above Python versions or Linux distributions.

Main Project Goals

• To test OpenStakc and Red Hat OpenStack Platform projects before they are released.
• To provide a Python framework to write system scenario test cases (create and test workloads), to write white boxing test cases (to log to cloud nodes for internal inspection purpose), to write disruptive test cases (to simulate service disruptions like for example rebooting/interrupting a service to verify cloud reliability).
• To provide Ansible roles to implement a work-flow designed to run an ordered sequence of test cases groups (like for example tests that creates resources and verify they are working, tests that execute cloud disruptions, and finally tests that verify if resources initially created are still working). The main use of these roles is writing continuous integration jobs for Zuul (via bare Ansible roles) or other services like Jenkins (via the InfraRed plug-in).
• To verify previously created workloads are working fine after executing OpenStack nodes update/upgrade.
• To provide tools to monitor and recollect the healthy status of the cloud as seen from user perspective (black-box testing) or from inside (white-box testing).
