Test Big Cloud Operations
|
|
-------------------------
|
|
|
|
Tobiko is an OpenStack testing framework focusing on areas mostly
|
|
complementary to `Tempest <https://docs.openstack.org/tempest/latest/>`__.
|
|
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 3.8
|
|
- Python 3.9
|
|
- Python 3.10 (new)
|
|
|
|
and below Linux distributions:
|
|
|
|
- CentOS 7 / RHEL 7 (with Python 3.6)
|
|
- CentOS 8 / RHEL 8 (with Python 3.6)
|
|
- CentOS 9 / RHEL 8 (with Python 3.9) (new)
|
|
- Fedora 34 (with Python 3.9)
|
|
- Fedora 35 (with Python 3.10)
|
|
- Ubuntu Focal (with Python 3.8)
|
|
|
|
Tobiko has also been tested for development purposes with below OSes:
|
|
|
|
- OSX (with Python 3.6 to 3.10)
|
|
- Ubuntu Bionic (with Python 3.6)
|
|
|
|
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.
|
|
|
|
There is also a Docker file that can be used to create a container for running
|
|
test cases from any node that do support containers execution.
|
|
|

Main Project Goals
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
- To test OpenStack 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 verify previously created workloads are working fine after executing
|
|
OpenStack nodes update/upgrade.
|
|
- 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 implementing a workflow designed to run an ordered
|
|
sequence of test suites. For example a workflow could do below steps:
|
|
|
|
- creates workloads;
|
|
- run disruptive test cases (IE reboot OpenStack nodes or services);
|
|
- verify workloads are still working.
|
|
|
|
The main use of these roles is writing continuous integration jobs for Zuul
|
|
or other services like Jenkins (IE by using the Tobiko InfraRed plug-in).
|
|
- To provide tools to monitor and recollect the healthy status of the cloud as
|
|
seen from user perspective (black-box testing) or from an inside point of
|
|
view (white-box testing built around SSH client).
