Testing
|

=======
|

ceph-ansible has the ability to test different scenarios (collocated journals
|
||||
or dmcrypt OSDs for example) in an isolated, repeatable, and easy way.
|
||||
|
||||
These tests can run locally with VirtualBox or via libvirt if available, which
|
||||
removes the need to solely rely on a CI system like Jenkins to verify
|
||||
a behavior.

Layout and conventions
|
||||
----------------------
|
||||
Test files and directories follow a few conventions, which makes it easy to
|
||||
create (or expect) certain interactions between tests and scenarios.
|
||||
|
||||
All tests are in the ``tests`` directory. Scenarios are defined in
|
||||
``tests/functional/`` and use the following convention for directory
|
||||
structure::
|
||||
|
||||
tests/functional/<distro>/<distro version>/<scenario name>/
|
||||
|
||||
For example: ``tests/functional/centos/7/journal-collocation``
|
||||
|
||||
Within a test scenario there are a few files that define what that specific
|
||||
scenario needs for the tests, like how many OSD nodes or MON nodes. Tls
|
||||
|
||||
At the very least, a scenario will need these files:
|
||||
|
||||
* ``Vagrantfile``: must be symlinked from the root directory of the project
|
||||
* ``hosts``: An Ansible hosts file that defines the machines part of the
|
||||
cluster
|
||||
* ``group_vars/all``: if any modifications are needed for deployment, this
|
||||
would override them. Additionally, further customizations can be done. For
|
||||
example, for OSDs that would mean adding ``group_vars/osds``
|
||||
* ``vagrant_variables.yml``: Defines the actual environment for the test, where
|
||||
machines, networks, disks, linux distro/version, can be defined.

Running Tests
|
||||
=============
|
||||
Although tests run continuously in CI, a lot of effort was put into making it
|
||||
easy to run in any environment, as long as a couple of requirements are met.
|
||||
|
||||
|
||||
.. _dependencies:
|
||||
|
||||
Dependencies
|
||||
------------
|
||||
There are some Python dependencies, which are listed in a ``requirements.txt``
|
||||
file within the ``tests/`` directory. These are meant to be installed using
|
||||
Python install tools (pip in this case)::
|
||||
|
||||
pip install -r tests/requirements.txt
|
||||
|
||||
For virtualization, either libvirt or VirtualBox is needed (there is native
|
||||
support from the harness for both). This makes the test harness even more
|
||||
flexible as most platforms will be covered by either VirtualBox or libvirt.
|
||||
|
||||
|
||||
.. _running_a_scenario:
|
||||
|
||||
Running a scenario
|
||||
------------------
|
||||
Tests are driven by ``tox``, a command line tool to run a matrix of tests defined in
|
||||
a configuration file (``tox.ini`` in this case at the root of the project).
|
||||
|
||||
For a thorough description of a scenario see :ref:`test_scenarios`.
|
||||
|
||||
To run a single scenario, make sure it is available (should be defined from
|
||||
``tox.ini``) by listing them::
|
||||
|
||||
tox -l
|
||||
|
||||
In this example, we will use the ``kraken-ansible2.2-xenial_cluster`` one. The
|
||||
harness defaults to ``VirtualBox`` as the backend, so if you have that
|
||||
installed in your system then this command should just work::
|
||||
|
||||
tox -e kraken-ansible2.2-xenial_cluster
|
||||
|
||||
And for libvirt it would be::
|
||||
|
||||
tox -e kraken-ansible2.2-xenial_cluster -- --provider=libvirt
|
||||
|
||||
|
||||
.. warning:: Depending on the type of scenario and resources available, running
|
||||
these tests locally in a personal computer can be very resource intensive.
|
||||
|
||||
.. note:: Most test runs take between 20 and 40 minutes depending on system
|
||||
resources
|
||||
|
||||
The command should bring up the machines needed for the test, provision them
|
||||
with ceph-ansible, run the tests, and tear the whole environment down at the
|
||||
end.
|
||||
|
||||
|
||||
The output would look something similar to this trimmed version::
|
||||
|
||||
kraken-ansible2.2-xenial_cluster create: /Users/alfredo/python/upstream/ceph-ansible/.tox/kraken-ansible2.2-xenial_cluster
|
||||

|
||||
Bringing machine 'osd0' up with 'virtualbox' provider...
|
||||
...
|
||||
|
||||
|
||||
After all the nodes are up, ceph-ansible will provision them, and run the
|
||||
playbook(s)::
|
||||
|
||||
...
|
||||

|

...
|

|

Once the whole environment is all running the tests will be sent out to the
