This page describes how to:
* Run tests locally using `` ansible-test ``
* Extend
2017-04-14 00:46:21 +00:00
Requirements
============
There are no special requirements for running `` ansible-test `` on Python 2.7 or later.
The `` argparse `` package is required for Python 2.6.
The requirements for each `` ansible-test `` command are covered later.
Setup
=====
2017-04-28 08:08:26 +00:00
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.
2017-04-14 00:46:21 +00:00
#. Clone your fork: `` git clone git@github.com:USERNAME/ansible.git ``
2017-04-28 08:08:26 +00:00
#. Install the optional `` argcomplete `` package for tab completion (highly recommended)::
2017-04-14 00:46:21 +00:00
2017-04-28 08:08:26 +00:00
pip install argcomplete
activate-global-python-argcomplete
# Restart your shell to complete global activation.
2017-04-14 00:46:21 +00:00
#. Configure your environment to run from your clone (once per shell): `` . hacking/env-setup ``
2017-04-28 08:08:26 +00:00
#. `` 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
------
The `` --remote `` option runs tests in a cloud hosted environment.
An API key is required to use this feature.
Recommended for integration tests.

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.
Interactive Shell
=================
Use the `` ansible-test shell `` command to get an interactive shell in the same environment used to run tests. Examples:
* `` ansible-test shell --docker `` - Open a shell in the default docker container.
* `` ansible-test shell --tox --python 3.6 `` - Open a shell in the Python 3.6 `` tox `` environment.
Code Coverage
=============
Add the `` --coverage `` option to any test command to collect code coverage data.
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.
