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 in py26:

tox -e py26

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 py27 -- 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 py27 -- --tests glance.tests.unit.test_auth.py:TestImageRepoProxy.test_list
