Integration tests
|
|
=================
|
|
|
|
The ansible integration system.
|
|
|
|
Tests for playbooks, by playbooks.
|
|
|
|
Some tests may require credentials. Credentials may be specified with `credentials.yml`.
|
|
|
|
Tests should be run as root.
|
|
|
|
Quick Start
|
|
===========
|
|
|
|
To get started quickly using Docker containers for testing,
|
|
see [Tests in Docker containers](#tests-in-docker-containers).
|
|
|
|
Configuration
|
|
=============
|
|
|
|
Making your own version of `integration_config.yml` can allow for setting some
|
|
tunable parameters to help run the tests better in your environment. Some
|
|
tests (e.g. cloud) will only run when access credentials are provided. For
|
|
more information about supported credentials, refer to `credentials.template`.
|
|
|
|
Prerequisites
|
|
=============
|
|
|
|
The tests will assume things like hg, svn, and git are installed and in path.
|
|
|
|
(Complete list pending)
|
|
|
|
Non-destructive Tests
|
|
=====================
|
|
|
|
These tests will modify files in subdirectories, but will not do things that install or remove packages or things
|
|
outside of those test subdirectories. They will also not reconfigure or bounce system services.
|
|
|
|
Run as follows:
|
|
|
|
make non_destructive
|
|
|
|
You can select specific tests with the --tags parameter.
|
|
|
|
TEST_FLAGS="--tags test_vars_blending" make
|
|
|
|
Destructive Tests
|
|
=================
|
|
|
|
These tests are allowed to install and remove some trivial packages. You will likely want to devote these
|
|
to a virtual environment. They won't reformat your filesystem, however :)
|
|
|
|
make destructive
|
|
|
|
Cloud Tests
|
|
===========
|
|
|
|
Cloud tests exercise capabilities of cloud modules (e.g. ec2_key). These are
|
|
not 'tests run in the cloud' so much as tests that leverage the cloud modules
|
|
and are organized by cloud provider.
|
|
|
|
In order to run cloud tests, you must provide access credentials in a file
|
|
named `credentials.yml`. A sample credentials file named
|
|
`credentials.template` is available for syntax help.
|
|
|
|
|
|
Provide cloud credentials:
|
|
cp credentials.template credentials.yml
|
|
${EDITOR:-vi} credentials.yml
|
|
|
|
Run the tests:
|
|
make cloud
|
|
|
|
*WARNING* running cloud integration tests will create and destroy cloud
|
|
resources. Running these tests may result in additional fees associated with
|
|
your cloud account. Care is taken to ensure that created resources are
|
|
removed. However, it is advisable to inspect your AWS console to ensure no
|
|
unexpected resources are running.
|
|
|
|
Windows Tests
|
|
=============
|
|
|
|
These tests exercise the winrm connection plugin and Windows modules. You'll
|
|
need to define an inventory with a remote Windows 2008 or 2012 Server to use
|
|
for testing, and enable PowerShell Remoting to continue.
|
|
|
|
Running these tests may result in changes to your Windows host, so don't run
|
|
them against a production/critical Windows environment.
|
|
|
|
Enable PowerShell Remoting (run on the Windows host via Remote Desktop):
|
|
Enable-PSRemoting -Force
|
|
|
|
Define Windows inventory:
|
|
cp inventory.winrm.template inventory.winrm
|
|
${EDITOR:-vi} inventory.winrm
|
|
|
|
Run the tests:
|
|
make test_winrm
|
|
|
|
Tests in Docker containers
|
|
==========================
|
|
|
|
If you have a Linux system with Docker installed, running integration tests using the same Docker containers used by
|
|
the Ansible continuous integration (CI) system is recommended.
|
|
|
|
> Using Docker Engine to run Docker on a non-Linux host is not recommended. Some tests, such as those that manage
|
|
> services or use local SSH connections are known to fail in such an environment. For best results, install Docker on a
|
|
> full Linux distribution such as Ubuntu, running on real hardware or in a virtual machine.
|
|
|
|
## Running Integration Tests
|
|
|
|
To run all integration test targets with the default settings in a Centos 7 container, run `make integration` from the repository root.
|
|
|
|
You can also run specific tests or select a different Linux distribution.
|
|
For example, to run the test `test_ping` from the non_destructive target on a Ubuntu 14.04 container:
|
|
|
|
- go to the repository root
|
|
- and execute `make integration IMAGE=ansible/ansible:ubuntu1404 TARGET=non_destructive TEST_FLAGS='--tags test_ping'`
|
|
|
|
## Container Images
|
|
|
|
Use the prefix `ansible/ansible:` with the image names below.
|
|
|
|
> Running `make integration` will automatically download the container image you have specified, if it is not already
|
|
> available. However, you will be responsible for keeping the container images up-to-date using `docker pull`.
|
|
|
|
### Python 2
|
|
|
|
Most container images are for testing with Python 2:
|
|
|
|
- centos6
|
|
- centos7
|
|
- fedora-rawhide
|
|
- fedora23
|
|
- opensuseleap
|
|
- ubuntu1204 (requires `PRIVILEGED=true`)
|
|
- ubuntu1404 (requires `PRIVILEGED=true`)
|
|
- ubuntu1604
|
|
|
|
### Python 3
|
|
|
|
To test with Python 3 you must set `PYTHON3=1` and use the following images:
|
|
|
|
- ubuntu1604py3
|
|
|
|
## Additional Options
|
|
|
|
There are additional environment variables that can be used. A few of the more useful ones:
|
|
|
|
- `KEEP_CONTAINERS=onfailure` - Containers will be preserved if tests fail.
|
|
- `KEEP_CONTAINERS=1` - Containers will always be preserved.
|
|
- `SHARE_SOURCE=1` - Changes to source from the host or container will be shared between host and container.
|
|
_**CAUTION:** Files created by the container will be owned by root on the host._
