Testing with Molecule

This role is locally tested with the use of Molecule, the configuration is located at: molecule/default.
The Molecule tests are run (using the docker driver) on Dockerhub images built for this purpose:

Some specific configurations might require a full OS instead of a minimal container image. In these use-cases make use of molecule driver for vagrant with the libvirt provider. The Molecule driver and platform configuration part could look something like this:

driver:
  name: vagrant
  provider:
    name: libvirt
platforms:
  - name: ansible_role_ad_membership-ansible-molecule-centos-7
    box: centos/7
    imemory: 1024
    cpus: 1

CI/CD with Travis CI

This role uses Travis CI to run online tests with the use of Molecule and pushes notifications to import the role into Ansible Galaxy once the tests are successful. The Travis CI configuration is located at the root of the Ansible role .travis.yml
