Python program to help test or validate Ansible modules.

``validate-modules`` is one of the ``ansible-test`` Sanity Tests, see :ref:`testing_sanity` for more information.

Originally developed by Matt Martz (@sivel)


Usage
=====

.. code:: shell

    cd /path/to/ansible/source
    source hacking/env-setup
    ansible-test sanity --test validate-modules

Help
====

.. code:: shell

    usage: validate-modules [-h] [-w] [--exclude EXCLUDE] [--arg-spec]
                            [--base-branch BASE_BRANCH] [--format {json,plain}]
                            [--output OUTPUT]
                            modules [modules ...]

    positional arguments:
      modules               Path to module or module directory

    optional arguments:
      -h, --help            show this help message and exit
      -w, --warnings        Show warnings
      --exclude EXCLUDE     RegEx exclusion pattern
      --arg-spec            Analyze module argument spec
      --base-branch BASE_BRANCH
                            Used in determining if new options were added
      --format {json,plain}
                            Output format. Default: "plain"
      --output OUTPUT       Output location, use "-" for stdout. Default "-"


Extending validate-modules
==========================

The ``validate-modules`` tool has a `schema.py <https://github.com/ansible/ansible/blob/devel/test/lib/ansible_test/_data/sanity/validate-modules/validate_modules/schema.py>`_ that is used to validate the YAML blocks, such as ``DOCUMENTATION`` and ``RETURNS``.
