Running the tests¶
You can run flake8 and the pytest suite inside Docker, using:
docker-compose run backend ./runtests.sh
Or for more control, run each tool individually, by first running:
docker-compose run backend bash
...which saves having to wait for docker-compose to spin up for every test run.
yarn build will generate a
.build directory which will be seen within the
If you don't have
yarn working on your host you can run this instead
docker-compose run frontend sh -c "yarn && yarn build"
Then run the individual tools within that shell, like so:
pytest tests/ pytest tests/log_parser/test_tasks.py pytest tests/etl/test_job_loader.py -k test_ingest_pulse_jobs
To run all tests, including slow tests that are normally skipped, use:
pytest --runslow tests/
For more options, see
pytest --helpor https://docs.pytest.org/en/stable/usage.html.
Hide Jobs with Tiers¶
To hide jobs we use the job's
tier setting. Jobs with
tier of 3 are
hidden by default. For TaskCluster, edit the task definition to include the
tier setting in the Treeherder section.
Profiling API endpoint performance¶
On our development (vagrant) instance we have django-debug-toolbar installed, which can give information on exactly what SQL is run to generate individual API endpoints. Navigate to an endpoint (example: http://localhost:8000/api/repository/) and you should see the toolbar to your right.
Connecting to Services Running inside Docker¶
Treeherder uses various services to function, eg MySQL, etc. At times it can be useful to connect to them from outside the Docker environment.
docker-compose.yml file defines how internal ports are mapped to the host OS' ports.
In the below example we're mapping the container's port 3306 (MySQL's default port) to host port 3306.
# This is a line from the docker-compose.yml file ports: - '3306:3306'
Any forwarded ports will block usage of that port on the host OS even if there isn't a service running inside the VM talking to it.
With MySQL exposed at port 3306 you can connect to it from your host OS with the following credentials:
- password: leave blank
Other services running inside the Compose project, can be accessed in the same way.
Releasing a new version of the Python client¶
- Determine whether the patch, minor or major version should be bumped, by inspecting the client Git log.
- File a separate bug for the version bump.
- Open a PR to update the version listed in client.py.
Use Twine to publish both the sdist and the wheel to PyPI, by running the following from the root of the Treeherder repository:
> pip install -U twine wheel > cd treeherder/client/ > rm -rf dist/* > python setup.py sdist bdist_wheel > twine upload dist/*
- File a
Release Engineering::Builddutybug requesting that the sdist and wheel releases (plus any new dependent packages) be added to the internal PyPI mirror. For an example, see bug 1236965.
