README.md

openQA tests for the Rocky Linux distribution

This repository contains tests and images for testing Rocky with openQA. The fedora_openqa library and CLI are used for scheduling tests, and createhdds is used for creating base disk images for the test. For openQA installation instructions, see the Fedora openQA wiki page.

Issues

Issues and pull requests are tracked in os-autoinst-distri-fedora Pagure. Pagure uses a Github-like pull request workflow, so if you're familiar with that, you can easily submit Pagure pull requests. If not, you can read up in the Pagure documentation.

Requirements

Obviously, this repository is little use without access to an openQA installation. Also, the tests themselves require the perl libraries JSON and REST::Client to be installed on the worker host; in Fedora, the package names are perl-JSON and perl-REST-Client. To load templates from this repository, you will need the upstream client tools (packaged as openqa-client in Fedora) and the dependencies of fifloader.py (see below for more on this tool) installed. Those dependencies are Python 3 and the jsonschema library. For running the unit tests, you will additionally need pytest and tox.

Test development

See official documentation on:

See this example repo on how tests should be structured.

See the results readme for the expected test commands and results for Rocky

FIF template format

The test templates in this repository (files ending in fif.json) are not in the same format as expected by and are not directly compatible with the upstream template loader. They are in a format referred to as 'FIF' ('Fedora Intermediate Format') which is parsed into the upstream format by the fifloader.py utility found in this repository. This format is intended to be more convenient for human reading and editing. It is more fully explained in the docstring at the top of fifloader.py. Please refer to this when adding new tests to the templates. A command like ./fifloader.py --load templates.fif.json templates-updates.fif.json can be used to load templates in the FIF format (this converts them to the upstream format, and calls the upstream template loader on the converted data). See ./fifloader.py -h for further details on fifloader.py.

main.pm modular architecture

Since openQA uses only one entrypoint for all tests (main.pm), we have decided to utilize this feature and make tests modular. It means that basic passing through main.pm (without any variables set) results in most basic installation test executed. Developer can customize it with additional variables (for example by setting PACKAGE_SET=minimal to do installation only with minimal package set).

Make your test modular, so that it utilizes _boot_to_anaconda.pm, _software_selection.pm and _do_install_and_reboot.pm tests (that are loaded automatically). Break your test into smaller parts, each dealing with one specific feature (e. g. partitioning, user creation...) and add their loading into main.pm based on reasonable variable setting (so they can be used in other tests also).

Fedora installation (and consequently main.pm) consists of several parts:

Booting into Anaconda or booting live image and starting Anaconda

Since there isn't much variation between tests in this step, we have developed universal _boot_to_anaconda.pm test that is loaded automatically each time except when ENTRYPOINT or UPGRADE is set (see VARIABLES.md).

To customize this step, you can set following variables:

  • GRUB is appended to kernel line before boot. You can set for example inst.updates here.
  • If KICKSTART is set, this part of installation ends here (program doesn't wait for Anaconda to appear). Note that you should set inst.ks yourself by setting GRUB variable.
  • If LIVE is set, program waits for desktop to appear and then clicks on "Install to Hard Drive" button.

Customizing installation by interacting with Anaconda spokes

Most of the differences between tests take place in this part. If you want to add another installation test, you will probably put your variable checking and test loading here. All tests in this part should start on Anaconda's main hub and after they done its part, they should go back to Anaconda's main hub so that next test could be executed. In this phase, universal _software_selection.pm test is loaded that handles selecting what software to install.

To customize this step, you can set following variables:

  • Set PACKAGE_SET to install required package set on "Software selection spoke" - you have to provide correct needles with the name of anaconda_${PACKAGE_SET}_highlighted and anaconda_${PACKAGE_SET}_selected.
  • Set ENCRYPT_PASSWORD to encrypt disk, value of this variable is used as an actual password.

Installing Rocky Linux and waiting for Rocky Linux to reboot

After all customizations are finished, _do_install_and_reboot.pm test is automatically loaded. It starts installation, creates user and sets root password when required, waits for installation to finish and reboots into installed system. Only variables that control flow in this part are these:

  • ROOT_PASSWORD to set root password to this value.
  • When set, USER_LOGIN and USER_PASSWORD are used to create user in Anaconda.

Post-install phase

After installation is finished and installed system is fully booted, you can run additional tests as checks that installed system has correct attributes - that correct file system is used, that RAID is used etc.

Test inheritance

Your test can inherit from basetest, installedtest or anacondatest. Each provides relevant methods that are documented in-line, so read the files (lib/anacondatest.pm, lib/installedtest.pm) for information on these.

  • basetest: A base class provided by os-autoinst - it has empty post_fail_hook() and doesn't set any flags.
  • anacondatest: should be used in tests where Anaconda is running. It uploads Anaconda logs (for example anaconda.log or packaging.log) in post_fail_hook().
  • installedtest: should be used in tests that are running on installed system (either in postinstall phase or in upgrade tests).

There are also several modules that export utility functions, currently utils, anaconda, freeipa, packagetest and tapnet. Your test can use any of these modules and then directly call the functions they export. Again, the functions are documented in-line.

New test development workflow

  1. Put each part of your test as a separate file into tests/ directory, reimplementing run() method and test_flags() method, inheriting from one of the classes mentioned above.
  2. Set correct variables (so that all test parts you have made are executed) in WebUI -> Test suites.
  3. Link your newly created Test suite to medium type in WebUI -> Job groups.
  4. Run test (see fedora_openqa repository).
  5. Create needles (images) by using interactive mode and needles editor in WebUI.
  6. Add new test suite and profiles into templates.fif.json file (and/or templates-updates.fif.json, if the test is applicable to the update testing workflow)
  7. Add new Test suite and Test case into conf_test_suites.py file in fedora_openqa repository.
  8. Run tox. This will check the templates are valid.
  9. Open pull request for the os-autoinst-distri-fedora changes in Pagure. Pagure uses a Github-style workflow (summary: fork the project via the web interface, push your changes to a branch on your fork, then use the web interface to submit a pull request). See the Pagure documentation for more details.
  10. Open a pull request in fedora_openqa Pagure for any necessary fedora_openqa changes.

Language handling

Tests can run in different languages. To set the language which will be used for a test, set the LANGUAGE variable for the test suite. The results of this will be:

  1. The value set will be typed into the language search box in anaconda.
  2. Any needle with at least one tag that starts with LANGUAGE will be unregistered unless it has the tag LANGUAGE-(LANGUAGE) (where (LANGUAGE) is the value set, forced to upper-case).
  3. As a consequence, the chosen language will be selected at the anaconda Welcome screen.

It is very important, therefore, that needles have the correct tags. Any needle which is expected to match for tests run in any language must have no LANGUAGE tags. Other needles must have the appropriate tag(s) for the languages they are expected to match. The safest option if you are unsure is to set no LANGUAGE tag(s). The only danger of this is that missing translations may not be caught.

Note that tags of the form ENV-INSTLANG-(anything) are useless artefacts and should be removed.

Contribution Approval Guidelines

Use the following guidelines to understand the level of approval needed to merge your contributions:

  1. Pull requests and merge requests to a non-default branch will require 1 visual inspection approval to merge, provided all comments are addressed and no requests for followup are outstanding.
  2. Pull and merge requests to the default branch (rocky) require 2 visual inspection approvals and 1 openQA automation approval to merge.
  3. When public openQA infrastructure is available, all pull requests should initiate an openQA build, which must pass prior to merge.
