Setup
=====
The code and tests are in the same GitHub repository, to get a local copy do
#. Fork the `ansible/ansible <https://github.com/ansible/ansible/>`_ repository on GitHub.
#. Clone your fork: ``git clone git@github.com:USERNAME/ansible.git``
#. Install the optional ``argcomplete`` package for tab completion (highly recommended)::
pip install argcomplete
activate-global-python-argcomplete
# Restart your shell to complete global activation.
#. Configure your environment to run from your clone (once per shell): ``. hacking/env-setup``
#. ``ansible``, ``ansible-playbook`` and ``ansible-test`` will now be in your ``PATH``
Test Environments
=================
Most ``ansible-test`` commands support running in one or more isolated test environments to simplify testing.
Local
-----
The ``--local`` option runs tests locally without the use of an isolated test environment.
This is the default behavior.
Recommended for ``compile`` tests.
See the `command requirements directory <runner/requirements/>`_ for the requirements for each ``ansible-test`` command.
Requirements files are named after their respective commands.
See also the `constraints <runner/requirements/constraints.txt>`_ applicable to all commands.
Use the ``--requirements`` option to automatically install ``pip`` requirements relevant to the command being used.
Docker
------
The ``--docker`` option runs tests in a docker container.
Recommended for ``integration`` tests.
This option accepts an optional docker container image.
See the `list of supported docker images <runner/completion/docker.txt>`_ for options.
Use the ``--docker-no-pull`` option to avoid pulling the latest container image.
This is required when using custom local images that are not available for download.
Tox
---
The ``--tox`` option run tests in a ``tox`` managed Python virtual environment.
Recommended for ``windows-integration`` and ``units`` tests.
The following Python versions are supported:
* 2.6
* 2.7
* 3.5
* 3.6
By default, test commands will run against all supported Python versions when using ``tox``.
Use the ``--python`` option to specify a single Python version to use for test commands.
Remote
------
@ -92,40 +33,6 @@ An API key is required to use this feature.
See the `list of supported platforms and versions <https://github.com/ansible/ansible/blob/devel/test/runner/completion/remote.txt>`_ for additional details.
General Usage
=============
Tests are run with the ``ansible-test`` command.
Consult ``ansible-test --help`` for usage information not covered here.
Use the ``--explain`` option to see what commands will be executed without actually running them.
Running Tests
=============
There are four main categories of tests, each in their own directory.
* `compile <compile/>`_ - Python syntax checking for supported versions. Examples:
* ``ansible-test compile`` - Check syntax for all supported versions.
* ``ansible-test compile --python 3.5`` - Check only Python 3.5 syntax.
* `sanity <sanity/>`_ - Static code analysis and general purpose script-based tests. Examples:
* ``ansible-test sanity --tox --python 2.7`` - Run all sanity tests on Python 2.7 using ``tox``.
* ``ansible-test sanity --test pep8`` - Run the ``pep8`` test without ``tox``.
* `integration <integration/>`_ - Playbook based tests for modules and core engine functionality. Examples:
* ``ansible-test integration ping --docker`` - Run the ``ping`` module test using ``docker``.
* ``ansible-test windows-integration windows/ci/`` - Run all Windows tests covered by CI.
* `units <units/>`_ - API oriented tests using mock interfaces for modules and core engine functionality. Examples:
* ``ansible-test units --tox`` - Run all unit tests on all supported Python versions using ``tox``.
* ``ansible-test units --tox --python 2.7 test/units/vars/`` - Run specific tests on Python 2.7 using ``tox``.
Consult each of the test directories for additional details on usage and requirements.

Code Coverage
`````````````
Most ``ansible-test`` commands allow you to collect code coverage, this is particularly useful when to indicate where to extend testing.
To collect coverage data add the ``--coverage`` argument to your ``ansible-test`` command line:
.. code:: shell
ansible-test units --coverage
ansible-test coverage html
ansible-test units --coverage apt
ansible-test coverage html
Results will be written to ``test/results/reports/coverage/index.html``
Reports can be generated in several different formats:
* ``ansible-test coverage report`` - Console report.
* ``ansible-test coverage html`` - HTML report.
* ``ansible-test coverage xml`` - XML report.
To clear data between test runs, use the ``ansible-test coverage erase`` command. For a full list of features see the online help::
ansible-test coverage --help
