Testing
|
|
=======
|
|
|
|
Cinder contains a few different test suites in the cinder/tests/ directory. The
|
|
different test suites are Unit Tests, Functional Tests, and Tempest Tests.
|
|
|
|
Test Types
|
|
----------
|
|
|
|
|
|
Unit Tests
|
|
~~~~~~~~~~
|
|
|
|
Unit tests are tests for individual methods, with at most a small handful of
|
|
modules involved. Mock should be used to remove any external dependencies.
|
|
|
|
All significant code changes should have unit test coverage validating the code
|
|
happy path and any failure paths.
|
|
|
|
Any proposed code change will be automatically rejected by the OpenStack
|
|
Jenkins server [#f1]_ if the change causes unit test failures.
|
|
|
|
Functional Tests
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
Functional tests validate a code path within Cinder. These tests should
|
|
validate the interaction of various modules within the project to verify the
|
|
code is logically correct.
|
|
|
|
Functional tests run with a database present and may start Cinder services to
|
|
accept requests. These tests should not need to access an other OpenStack
|
|
non-Cinder services.
|
|
|
|
Tempest Tests
|
|
~~~~~~~~~~~~~
|
|
|
|
The tempest tests in the Cinder tree validate the operational correctness
|
|
between Cinder and external components such as Nova, Glance, etc. These are
|
|
integration tests driven via public APIs to verify actual end user usage
|
|
scenarios.
|
|
|
|
Running the tests
|
|
-----------------
|
|
|
|
There are a number of ways to run tests currently, and there's a combination of
|
|
frameworks used depending on what commands you use. The preferred method is to
|
|
use tox, which calls ostestr via the tox.ini file.
|
|
|
|
Unit Tests
|
|
~~~~~~~~~~
|
|
|
|
To run all unit tests simply run::
|
|
|
|
tox
|
|
|
|
This will create a virtual environment, load all the packages from
|
|
test-requirements.txt and run all unit tests as well as run flake8 and hacking
|
|
checks against the code.
|
|
|
|
You may run individual test targets, for example only py27 tests, by running::
|
|
|
|
tox -e py27
|
|
|
|
Note that you can inspect the tox.ini file to get more details on the available
|
|
options and what the test run does by default.
|
|
|
|
Functional Tests
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
To run all functional tests, run::
|
|
|
|
tox -e functional
|
|
|
|
Tempest Tests
|
|
~~~~~~~~~~~~~
|
|
|
|
Tempest tests in the Cinder tree are "plugged in" to the normal tempest test
|
|
execution. To ensure the Cinder tests are picked up when running tempest, run::
|
|
|
|
cd /opt/stack/tempest
|
|
tox -e all-plugin
|
|
|
|
More information about tempest can be found in the `Tempest Documentation
|
|
<https://docs.openstack.org/tempest/latest/>`_.
|
|
|
|
Database Setup
|
|
~~~~~~~~~~~~~~~
|
|
|
|
Some unit and functional tests will use a local database. You can use
|
|
``tools/test-setup.sh`` to set up your local system the same way as
|
|
it's setup in the CI environment.
|
|
|
|
Running a subset of tests using tox
|
|
-----------------------------------
|
|
One common activity is to just run a single test, you can do this with tox
|
|
simply by specifying to just run py27 or py35 tests against a single test::
|
|
|
|
tox -epy27 -- -n cinder.tests.unit.test_volume.AvailabilityZoneTestCase.test_list_availability_zones_cached
|
|
|
|
Or all tests in the test_volume.py file::
|
|
|
|
tox -epy27 -- -n cinder.tests.unit.test_volume
|
|
|
|
You may also use regular expressions to run any matching tests::
|
|
|
|
tox -epy27 -- -r test_volume
|
|
|
|
For more information on these options and how to run tests, please see the
|
|
`ostestr documentation <https://docs.openstack.org/os-testr/latest/>`_.

Gotchas
|
|
-------
|
|
|
|
**Running Tests from Shared Folders**
|
|
|
|
If you are running the unit tests from a shared folder, you may see tests start
|
|
to fail or stop completely as a result of Python lockfile issues. You
|
|
can get around this by manually setting or updating the following line in
|
|
``cinder/tests/conf_fixture.py``::
|
|
|
|
CONF['lock_path'].SetDefault('/tmp')
|
|
|
|
Note that you may use any location (not just ``/tmp``!) as long as it is not
|
|
a shared folder.
|
|
|
|
**Running py35 tests**
|
|
|
|
You will need to install python3-dev in order to get py35 tests to run. If you
|
|
do not have this, you will get the following::
|
|
|
|
netifaces.c:1:20: fatal error: Python.h: No such file or directory
|
|
#include <Python.h>
|
|
^
|
|
compilation terminated.
|
|
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
