+Implemented as a `tox` plugin, `tox-ansible` provides a simple way to test Ansible content collections across multiple Python interpreters and Ansible versions.
 
 `tox-ansible` uses familiar python testing tools to perform the actual testing. It uses `tox` to create and manage the testing environments, `ansible-test sanity` to run the sanity tests, and `pytest` to run the unit and integration tests. This eliminated the black box nature of other approaches and allowed for more control over the testing process.
