Working with the Source

Setting up a Development Sandbox

1. Set up a server or virtual machine to run OpenStack using devstack.

2. Clone the ceilometer project to the machine:

   $ cd /opt/stack
   $ git clone https://git.openstack.org/openstack/ceilometer
   $ cd ./ceilometer

3. Once this is done, you need to setup the review process:

   $ git remote add gerrit ssh://<username>@review.openstack.org:29418/openstack/ceilometer.git

4. If you are preparing a patch, create a topic branch and switch to it before making any changes:

   $ git checkout -b TOPIC-BRANCH

Running the Tests

Ceiloemter includes an extensive set of automated unit tests which are run through tox.

1. Install tox:

   $ sudo pip install tox

2. Install the test dependencies:

   $ sudo pip install -r /opt/stack/ceilometer/test-requirements.txt

3. Run the unit and code-style tests:

   $ cd /opt/stack/ceilometer
   $ tox -e py27,pep8

   As tox is a wrapper around testr, it also accepts the same flags as testr. See the testr documentation for details about these additional flags.

   Use a double hyphen to pass options to testr. For example, to run only tests under tests/api/v2:

   $ tox -e py27 -- api.v2

• tox

Code Reviews

Ceilometer uses the OpenStack review process for all code and developer documentation contributions. Code reviews are managed through gerrit.
