Creating Unit Tests
For every new feature, unit tests should be created that both test and (implicitly) document the usage of said feature. If submitting a patch for a bug that had no unit test, a new passing unit test should be added. If a submitted bug fix does have a unit test, be sure to add a new one that fails without the patch and passes with the patch.
Running Tests
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.
Python packages may also have dependencies that are outside of tox's ability to install. Please refer to doc/source/devref/development.environment.rst for a list of those packages on Ubuntu, Fedora and Mac OS X.
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. In this case, 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
