Kayobe has a number of test suites covering different areas of code. Many tests
are run in virtual environments using
The following packages should be installed on the development system prior to running kayobe’s tests.
sudo apt-get install build-essential python-dev libssl-dev python-pip git
sudo yum install python-devel openssl-devel python-pip git gcc
Fedora 22 or higher:
sudo dnf install python-devel openssl-devel python-pip git gcc
sudo zypper install python-devel python-pip libopenssl-devel git
If your distro has at least
tox 1.8, use your system package manager to
python-tox package. Otherwise install this on all distros:
sudo pip install -U tox
You may need to explicitly upgrade
virtualenv if you’ve installed the one from
your OS distribution and it is too old (tox will complain). You can upgrade it
individually, if you need to:
sudo pip install -U virtualenv
Running Unit Tests Locally¶
If you haven’t already, the kayobe source code should be pulled directly from git:
# from your home or source directory cd ~ git clone https://opendev.org/x/kayobe.git cd kayobe
Running Unit and Style Tests¶
Kayobe defines a number of different tox environments in
default environments may be displayed:
To run all default environments:
To run one or more specific environments, including any of the non-default environments:
tox -e <environment>[,<environment>]
The following tox environments are provided:
- Run Ansible linter.
- Run Ansible tests for some ansible roles using Ansible playbooks.
- Run a syntax check for all Ansible files.
- Build Sphinx documentation.
- Run Ansible tests for some Ansible roles using the molecule test framework.
- Run style checks for all shell, python and documentation files.
- Run python unit tests for kayobe python module.
Unit tests follow the lead of OpenStack, and use
unittest. One difference
is that tests are run using the discovery functionality built into
unittest, rather than
stestr. Unit tests are found in
kayobe/tests/unit/, and should be added to cover all new python code.
Ansible Role Tests¶
Two types of test exist for Ansible roles - pure Ansible and molecule tests.
Pure Ansible Role Tests¶
These tests exist for the
kolla-ansible role, and are found in
ansible/<role>/tests/*.yml. The role is exercised using an ansible
Molecule Role Tests¶
Molecule is an Ansible role testing framework that allows roles to be tested in isolation, in a stable environment, under multiple scenarios. Kayobe uses Docker engine to provide the test environment, so this must be installed and running on the development system.
Molecule scenarios are found in
defined by the config file
Tests are written in python using the pytest framework, and are found in
Molecule tests currently exist for the
kolla-openstack role, and should be
added for all new roles where practical.
