Local Testing

The preferred way of locally testing the role is to use Docker and molecule (v1.25). You will have to install Docker on your system. See Get started for a Docker package suitable to for your system. All packages you need to can be specified in one line:

pip install ansible 'ansible-lint>=3.4.15' 'molecule==1.25.0' docker 'testinfra>=1.7.0,<=1.10.1' jmespath

This should be similar to one listed in .travis.yml file in install section. After installing test suit you can run test by running

molecule test

For more information about molecule go to their docs.
