Molecule is a Python package designed to aid in the development and testing of Ansible roles. It includes support for multiple instances, operating system distributions, virtualization providers, and test frameworks.

It leverages Vagrant, Docker, and OpenStack to manage virtual machines/containers, with support for multiple Vagrant providers (currently VirtualBox, Parallels, VMware Fusion, and Libvirt). Molecule supports Serverspec, Testinfra, or Goss (beta) to run tests. Molecule uses an Ansible playbook (playbook.yml), to execute the role and its tests.
