integration-aliases¶
Integration tests are executed by ansible-test
and reside in directories under test/integration/targets/
.
Each test MUST have an aliases
file to control test execution.
Aliases are explained in the following sections. Each alias must be on a separate line in an aliases
file.
Groups¶
Tests must be configured to run in exactly one group. This is done by adding the appropriate group to the aliases
file.
The following are examples of some of the available groups:
shippable/posix/group1
shippable/windows/group2
shippable/azure/group3
shippable/aws/group1
shippable/cloud/group1
Groups are used to balance tests across multiple CI jobs to minimize test run time. They also improve efficiency by keeping tests with similar requirements running together.
When selecting a group for a new test, use the same group as existing tests similar to the one being added. If more than one group is available, select one randomly.
Setup¶
Aliases can be used to execute setup targets before running tests:
setup/once/TARGET
- Run the targetTARGET
before the first target that requires it.setup/always/TARGET
- Run the targetTARGET
before each target that requires it.
Requirements¶
Aliases can be used to express some test requirements:
needs/privileged
- Requires--docker-privileged
when running tests with--docker
.needs/root
- Requires running tests asroot
or with--docker
.needs/ssh
- Requires SSH connections to localhost (or the test container with--docker
) without a password.needs/httptester
- Requires use of the http-test-container to run tests.
Dependencies¶
Some test dependencies are automatically discovered:
Ansible role dependencies defined in
meta/main.yml
files.Setup targets defined with
setup/*
aliases.Symbolic links from one target to a file in another target.
Aliases can be used to declare dependencies that are not handled automatically:
needs/target/TARGET
- Requires use of the test targetTARGET
.needs/file/PATH
- Requires use of the filePATH
relative to the git root.
Skipping¶
Aliases can be used to skip platforms using one of the following:
skip/freebsd
- Skip tests on FreeBSD.skip/osx
- Skip tests on macOS.skip/rhel
- Skip tests on RHEL.skip/docker
- Skip tests when running in a Docker container.
Platform versions, as specified using the --remote
option with /
removed, can also be skipped:
skip/freebsd11.1
- Skip tests on FreeBSD 11.1.skip/rhel7.6
- Skip tests on RHEL 7.6.
Windows versions, as specified using the --windows
option can also be skipped:
skip/windows/2008
- Skip tests on Windows Server 2008.skip/windows/2012-R2
- Skip tests on Windows Server 2012 R2.
Aliases can be used to skip Python major versions using one of the following:
skip/python2
- Skip tests on Python 2.x.skip/python3
- Skip tests on Python 3.x.
For more fine grained skipping, use conditionals in integration test playbooks, such as:
when: ansible_distribution in ('Ubuntu')
Miscellaneous¶
There are several other aliases available as well:
destructive
- Requires--allow-destructive
to run without--docker
or--remote
.hidden
- Target is ignored. Usable as a dependency. Automatic forsetup_
andprepare_
prefixed targets.
Unstable¶
Tests which fail sometimes should be marked with the unstable
alias until the instability has been fixed.
These tests will continue to run for pull requests which modify the test or the module under test.
This avoids unnecessary test failures for other pull requests, as well as tests on merge runs and nightly CI jobs.
There are two ways to run unstable tests manually:
Use the
--allow-unstable
option foransible-test
Prefix the test name with
unstable/
when passing it toansible-test
.
Tests will be marked as unstable by a member of the Ansible Core Team. GitHub issues will be created to track each unstable test.
Disabled¶
Tests which always fail should be marked with the disabled
alias until they can be fixed.
Disabled tests are automatically skipped.
There are two ways to run disabled tests manually:
Use the
--allow-disabled
option foransible-test
Prefix the test name with
disabled/
when passing it toansible-test
.
Tests will be marked as disabled by a member of the Ansible Core Team. GitHub issues will be created to track each disabled test.
Unsupported¶
Tests which cannot be run in CI should be marked with the unsupported
alias.
Most tests can be supported through the use of simulators and/or cloud plugins.
However, if that is not possible then marking a test as unsupported will prevent it from running in CI.
There are two ways to run unsupported tests manually:
Use the
--allow-unsupported
option foransible-test
Prefix the test name with
unsupported/
when passing it toansible-test
.
Tests will be marked as unsupported by the contributor of the test.
Cloud¶
Tests for cloud services and other modules that require access to external APIs usually require special support for testing in CI.
These require an additional alias to indicate the required test plugin.
Some of the available aliases are:
cloud/aws
cloud/azure
cloud/cs
cloud/foreman
cloud/openshift
cloud/tower
cloud/vcenter
Untested¶
Every module and plugin should have integration tests, even if the tests cannot be run in CI.
Issues¶
Tests that are marked as unstable or disabled will have an issue created to track the status of the test. Each issue will be assigned to one of the following projects:
