Contributing¶
Basic Details¶
If you would like to contribute to the development of OpenStack, you must follow the steps in this page:
Once those steps have been completed, changes to OpenStack should be submitted for review via the Gerrit tool, following the workflow documented at:
Release notes are managed through the tool
reno. This tool will create
a new file under the directory releasenotes that should
be checked in with the code changes.
Pull requests submitted through GitHub will be ignored.
Bugs should be filed on Launchpad, not GitHub:
Running the Tests for pbr¶
The testing system is based on a combination of tox and testr. The canonical
approach to running tests is to simply run the command tox. This will
create virtual environments, populate them with dependencies and run all of
the tests that OpenStack CI systems run. Behind the scenes, tox is running
testr run --parallel, but is set up such that you can supply any additional
testr arguments that are needed to tox. For example, you can run:
tox -- --analyze-isolation to cause tox to tell testr to add
--analyze-isolation to its argument list.
It is also possible to run the tests inside of a virtual environment
you have created, or it is possible that you have all of the dependencies
installed locally already. If you’d like to go this route, the requirements
are listed in requirements.txt and the requirements for testing are in
test-requirements.txt. Installing them via pip, for instance, is simply:
pip install -r requirements.txt -r test-requirements.txt
If you go this route, you can interact with the testr command directly.
Running testr run will run the entire test suite. testr run --parallel
will run it in parallel (this is the default incantation tox uses). More
information about testr can be found at: http://wiki.openstack.org/testr
