# Image Tests
|
|
|
|
We greatly appreciate Pull Requests that extend the automated tests that vet the basic functionality of the Docker images.
|
|
|
|
## How the Tests Work
|
|
|
|
A [GitHub Action workflow](https://github.com/jupyter/docker-stacks/blob/main/.github/workflows/docker-build-test-upload.yml)
|
|
runs tests against pull requests submitted to the `jupyter/docker-stacks` repository.
|
|
|
|
We use the `pytest` module to run tests on the image.
|
|
`conftest.py` and `pytest.ini` in the `tests` folder define the environment in which tests are run.
|
|
More info on `pytest` can be found [here](https://docs.pytest.org/en/latest/contents.html).
|
|
|
|
The actual image-specific test files are located in folders like `tests/by_image/<somestack>/` (e.g., `tests/by_image/docker-stacks-foundation/`, etc.).
|
|
|
|
```{note}
|
|
If your test is located in `tests/by_image/<somestack>/`, it will be run against the `jupyter/<somestack>` image and against all the [images inherited from this image](../using/selecting.md#image-relationships).
|
|
```
|
|
|
|
Many tests make use of global [pytest fixtures](https://docs.pytest.org/en/latest/reference/fixtures.html)
|
|
defined in the [conftest.py](https://github.com/jupyter/docker-stacks/blob/main/tests/conftest.py) file.
|
|
|
|
## Unit tests
|
|
|
|
You can add a unit test if you want to run a Python script in one of our images.
|
|
You should create a `tests/by_image/<somestack>/units/` directory, if it doesn't already exist, and put your file there.
|
|
Files in this folder will be executed in the container when tests are run.
|
|
You can see an [TensorFlow package example here](https://github.com/jupyter/docker-stacks/blob/HEAD/tests/by_image/tensorflow-notebook/units/unit_tensorflow.py).

|
## Contributing New Tests
|
|
|
|
Please follow the process below to add new tests:
|
|
|
|
1. Add your test code to one of the modules in the `tests/by_image/<somestack>/` directory or create a new module.
|
|
2. Build one or more images you intend to test and run the tests locally.
|
|
If you use `make`, call:
|
|
|
|
```bash
|
|
make build/<somestack>
|
|
make test/<somestack>
|
|
```
|
|
|
|
3. [Submit a pull request](https://github.com/PointCloudLibrary/pcl/wiki/A-step-by-step-guide-on-preparing-and-submitting-a-pull-request)
|
|
(PR) with your changes.
|
|
4. Watch for GitHub to report a build success or failure for your PR on GitHub.
|
|
5. Discuss changes with the maintainers and address any issues running the tests on GitHub.
