Running tests
|
|
=============
|
|
|
|
Kolla contains a suite of tests in the
|
|
``tests`` and ``kolla/tests`` directories.
|
|
|
|
Any proposed code change in gerrit is automatically rejected by the OpenStack
|
|
`Jenkins Job Builder <https://docs.openstack.org/infra/system-config/jjb.html>`__
|
|
if the change causes test failures.
|
|
|
|
It is recommended for developers to run the test suite before submitting patch
|
|
for review. This allows to catch errors as early as possible.
|
|
|
|
Preferred way to run the tests
|
|
------------------------------
|
|
|
|
The preferred way to run the unit tests is using ``tox``. It executes tests in
|
|
isolated environment, by creating separate virtualenv and installing
|
|
dependencies from the ``requirements.txt`` and ``test-requirements.txt`` files,
|
|
so the only package you install is ``tox`` itself:
|
|
|
|
.. code-block:: console
|
|
|
|
pip install tox
|
|
|
|
See the `unit testing <https://wiki.openstack.org/wiki/Testing#Unit_Tests>`__
|
|
section of the Testing wiki page for more information.
|
|
Following are some simple examples.
|
|
|
|
To run the Python 2.7 tests:
|
|
|
|
.. code-block:: console
|
|
|
|
tox -e py27
|
|
|
|
To run the style tests:
|
|
|
|
.. code-block:: console
|
|
|
|
tox -e pep8
|
|
|
|
To run multiple tests separate items by commas:
|
|
|
|
.. code-block:: console
|
|
|
|
tox -e py27,py35,pep8
|
|
|
|
Running a subset of tests
|
|
-------------------------
|
|
|
|
Instead of running all tests, you can specify an individual directory, file,
|
|
class or method that contains test code, for example, filter full names of
|
|
tests by a string.
|
|
|
|
To run the tests located only in the ``kolla/tests`` directory:
|
|
|
|
.. code-block:: console
|
|
|
|
tox -e py27 kolla.tests
|
|
|
|
To run the tests of a specific file say ``kolla/tests/test_set_config.py``:
|
|
|
|
.. code-block:: console
|
|
|
|
tox -e py27 test_set_config
|
|
|
|
To run the tests in the ``ConfigFileTest`` class in
|
|
the ``kolla/tests/test_set_config.py`` file:
|
|
|
|
.. code-block:: console
|
|
|
|
tox -e py27 test_set_config.ConfigFileTest
|
|
|
|
To run the ``ConfigFileTest.test_delete_path_not_exists`` test method in
|
|
the ``kolla/tests/test_set_config.py`` file:
|
|
|
|
.. code-block:: console
|
|
|
|
tox -e py27 test_set_config.ConfigFileTest.test_delete_path_not_exists
|
|
|
|
Coverage Report Generation
|
|
--------------------------
|
|
|
|
In order to get coverage report for Kolla, run the below command.
|
|
|
|
.. code-block:: console
|
|
|
|
tox -e cover
|
|
|
|
Debugging unit tests
|
|
--------------------
|
|
|
|
In order to break into the debugger from a unit test we need to insert
|
|
a breaking point to the code:
|
|
|
|
.. code-block:: python
|
|
|
|
import pdb; pdb.set_trace()
|
|
|
|
Then run :command:`tox` with the debug environment as one of the following:
|
|
|
|
.. code-block:: console
|
|
|
|
tox -e debug
|
|
tox -e debug test_file_name.TestClass.test_name
|
|
|
|
