Some variarations of the build matrix do not work. These are the variations and reasons why the build won't work:

amazonlinux	Dependency (python_pip) not available
ubuntu	Not idempotent on install stratis

Testing

Unit tests are done on every commit, pull request, release and periodically.

If you find issues, please register them in GitHub

Testing is done using Tox and Molecule:

Tox tests multiple ansible versions. Molecule tests multiple distributions.

To test using the defaults (any installed ansible version, namespace: robertdebock, image: fedora, tag: latest):

molecule test

# Or select a specific image:
image=ubuntu molecule test
# Or select a specific image and a specific tag:
image="debian" tag="stable" tox

Or you can test multiple versions of Ansible, and select images: Tox allows multiple versions of Ansible to be tested. To run the default (namespace: robertdebock, image: fedora, tag: latest) tests:

tox

# To run CentOS (namespace: `robertdebock`, tag: `latest`)
image="centos" tox
# Or customize more:
image="debian" tag="stable" tox
