tests directory
----------------
TBD. Expect tests for the collection itself to reside here.
Ansible Collections are tested much like Ansible itself, by using the
`ansible-test` utility which is released as part of Ansible, version 2.9.0 and
newer. Because Ansible Collections are tested using the same tooling as Ansible
itself, via `ansible-test`, all Ansible developer documentation for testing is
applicable for authoring Collections Tests with one key concept to keep in mind.
When reading the :ref:`developing_testing` documentation, there will be content
that applies to running Ansible from source code via a git clone, which is
typical of an Ansible developer. However, it's not always typical for an Ansible
Collection author to be running Ansible from source but instead from a stable
release, and to create Collections it is not necessary to run Ansible from
source. Therefore, when references of dealing with `ansible-test` binary paths,
command completion, or environment variables are presented throughout the
:ref:`developing_testing` documentation; keep in mind that it is not needed for
Ansible Collection Testing because the act of installing the stable release of
Ansible containing `ansible-test` is expected to setup those things for you.
