===========================
Testing Your OpenStack Code
===========================
------------
A Quickstart
------------
This is designed to be enough information for you to run your first tests.
Detailed information on testing can be found here: https://wiki.openstack.org/wiki/Testing
*Install pip*::
$ [apt-get | yum] install python-pip
More information on pip here: http://www.pip-installer.org/en/latest/
*Use pip to install tox*::
$ pip install tox
Run The Tests
-------------
*Navigate to the project's root directory and execute*::
$ tox
Note: completing this command may take a long time (depends on system resources)
also, you might not see any output until tox is complete.
Information about tox can be found here: http://testrun.org/tox/latest/
Run The Tests in One Environment
--------------------------------
Tox will run your entire test suite in the environments specified in the project tox.ini::
[tox]
envlist = <list of available environments>
To run the test suite in just one of the environments in envlist execute::
$ tox -e <env>
so for example, *run the test suite with the default OS version of Python 3*::
$ tox -e py3
or select a specific version, *run the test suite using Python 3.6*::
$ tox -e py36
Other useful tox options that can be specified when running the test suite are::
-v to increase verbosity of the output, can be repeated up to three times
based on the desired verbosity level
-r to recreate the virtual environment from scratch
Run One Test
------------
To run individual tests with tox:
if testr is in tox.ini, for example::
[testenv]
includes "python setup.py testr --slowest --testr-args='{posargs}'"
run individual tests with the following syntax::
$ tox -e <env> -- path.to.module:Class.test
so for example, *run the cpu_limited test in Nova*::
$ tox -e py36 -- nova.tests.test_claims:ClaimTestCase.test_cpu_unlimited
if nose is in tox.ini, for example::
[testenv]
includes "nosetests {posargs}"
run individual tests with the following syntax::
$ tox -e <env> -- --tests path.to.module:Class.test
so for example, *run the list test in Glance*::
$ tox -e py36 -- --tests glance.tests.unit.test_auth.py:TestImageRepoProxy.test_list
