Contribution Overview

OpenDev’s tools are hosted within the OpenDev collaboratory, and development for them uses workflows described in the OpenDev Infrastructure Manual:

Defect reporting and task tracking takes place here:!/project/opendev/git-review

Developing git-review

Either install bindep and run bindep test to check you have the needed tools, or review bindep.txt by hand.

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.

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

In 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:

Running tests

Running tests for git-review means running a local copy of Gerrit to check that git-review interacts correctly with it. This requires the following:

  • a Java Runtime Environment on the machine to run tests on

  • Internet access to download the gerrit.war file, or a locally cached copy (it needs to be located in a .gerrit directory at the top level of the git-review project)

To run git-review integration tests, use tox. For example, to test against Python 3.7:

tox -e py37
