Development & Testing

---------------------

This project uses [Molecule](http://molecule.readthedocs.io/) to aid in the

development and testing; the role is unit tested using

[Testinfra](http://testinfra.readthedocs.io/) and

[pytest](http://docs.pytest.org/).

To develop or test you'll need to have installed the following:

* Linux (e.g. [Ubuntu](http://www.ubuntu.com/))

* [Docker](https://www.docker.com/)

* [Python](https://www.python.org/) (including python-pip)

* [Ansible](https://www.ansible.com/)

* [Molecule](http://molecule.readthedocs.io/)

Because the above can be tricky to install, this project includes

[Molecule Wrapper](https://github.com/gantsign/molecule-wrapper). Molecule

Wrapper is a shell script that installs Molecule and it's dependencies (apart

from Linux) and then executes Molecule with the command you pass it.

To test this role using Molecule Wrapper run the following command from the

project root:

```bash

./moleculew test

```

Note: some of the dependencies need `sudo` permission to install.
