Before using the cron role, make sure your system is ready. I use this playbook to set everything up.

Testing Using Tox

Unit tests are performed with every commit, pull request, and release.

If you find any problems, please report them on GitHub.

Testing is done using Tox and Molecule:

Tox enables testing multiple versions of Ansible. Molecule allows for testing on various distributions.

To run default tests (with any installed Ansible version, namespace: tehtbl, image: ubuntu, tag: latest):

molecule test

# Or specify a different image:
IMAGE="ubuntu" molecule test

# Or choose a specific image and tag:
IMAGE="debian" TAG="stable" tox

You can also test multiple Ansible versions and choose the appropriate images:

Tox supports testing multiple versions of Ansible. To run the default tests:

tox

# To run tests for Ubuntu:
IMAGE="ubuntu" tox

# Or customize further:
IMAGE="debian" TAG="stable" tox -e py37-ansible-current

Testing Using Vagrant

To install vagrant plugins, run:

vagrant plugin install vagrant-reload

Start tests using VirtualBox as the provider:

vagrant up
