Testing packages¶

The package test suite¶

The salt repo provides a test suite for testing basic functionality of our packages at <repo-root>/pkg/tests/. You can run the install, upgrade, and downgrade tests. These tests run automatically on most PRs that are submitted against Salt.

Warning

These tests make destructive changes to your system because they install the built packages onto the system. They may also install older versions in the case of upgrades or downgrades. To prevent destructive changes, run the tests in an isolated system, preferably a virtual machine.

Setup¶

In order to run the package tests, the relenv onedir and built packages need to be placed in the correct locations.

Place all salt packages for the applicable testing version in <repo-root>/artifacts/pkg/.
The onedir must be located under <repo-root>/artifacts/.
Additionally, to ensure complete parity with Salt's CI/CD suite, place the nox virtual environment in <repo-root>/.nox/test-pkgs-onedir.

The following are a few ways this can be accomplished easily.

You can ensure parity by installing the package test suite through a few possible methods:

Using tools
Downloading individually

Using `tools`¶

Salt has preliminary support for setting up the package test suite in the tools command suite that is located under <repo-root>/tools/testsuite/. This method requires the Github CLI tool gh (https://cli.github.com/) to be properly configured for interaction with the salt repo.

Install the dependencies using this command:

pip install -r requirements/static/ci/py{python_version}/tools.txt

Download and extract the artifacts with this tools command:
tools ts setup --platform {linux|darwin|windows} --slug <operating-system-slug> --pr <pr-number> --pkg
The most common use case is to test the packages built on a CI/CD run for a given PR. To see the possible options for each argument, and other ways to utilize this command, use the following:
tools ts setup -h

Warning

You can only download artifacts from finished workflow runs. This is something imposed by the GitHub API. To download artifacts from a running workflow run, you either have to wait for the finish or cancel it.

Downloading individually¶

If the tools ts setup command doesn't work, you can download, unzip, and place the artifacts in the correct locations manually. Typically, you want to test packages built on a CI/CD run for a given PR. This guide explains how to set up for running the package tests using those artifacts. An analogous process can be performed for artifacts from nightly builds.

Find and download the artifacts:

Under the summary page for the most recent actions run for that PR, there is a list of available artifacts from that run that can be downloaded. Download the package artifacts by finding salt-<major>.<minor>+<number>.<sha>-<arch>-<pkg-type>. For example, the amd64 deb packages might look like: salt-3006.2+123.01234567890-x86_64-deb.

The onedir artifact will look like salt-<major>.<minor>+<number>.<sha>-onedir-<platform>-<arch>.tar.xz. For instance, the macos x86_64 onedir may have the name salt-3006.2+123.01234567890-onedir-darwin-x86_64.tar.xz.

Note

Windows onedir artifacts have .zip extensions instead of tar.xz

While it is optional, it is recommended to download the nox session artifact as well. This will have the form of nox-<os-name>-test-pkgs-onedir-<arch>. The amd64 Ubuntu 20.04 nox artifact may look like nox-ubuntu-20.04-test-pkgs-onedir-x86_64.
Place the artifacts in the correct location:

Unzip the packages and place them in <repo-root>/artifacts/pkg/.

You must unzip and untar the onedir packages and place them in <repo-root>/artifacts/. Windows onedir requires an additional unzip action. If you set it up correctly, the <repo-root>/artifacts/salt directory then contains the uncompressed onedir files.

Additionally, decompress the nox artifact and place it under <repo-root>/.nox/.

Running the tests¶

You can run the test suite run if all the artifacts are in the correct location.

Note

You need root access to run the test artifacts. Run all nox commands at the root of the salt repo and as the root user.

Install nox:
pip install nox
Run the install tests:
nox -e test-pkgs-onedir -- install
Run the upgrade or downgrade tests:
nox -e test-pkgs-onedir -- upgrade --prev-version <previous-version>
You can run the downgrade tests in the same way, replacing upgrade with downgrade.

Note

If you are testing upgrades or downgrades and classic packages are available for your system, replace upgrade or downgrade with upgrade-classic or downgrade-classic respectively to test against those versions.
