Adam Williamson da01d15406 Fix repo setup for Branched update tests (I hope) 
Branched update tests are all failing because the baseurl in
fedora.repo is incorrect for Branched. This is a rather hacky
fix for this problem. It relies on the scheduler setting the
DEVELOPMENT variable when the update is for Branched (I named
the variable DEVELOPMENT rather than BRANCHED to be more
future-proof).

Alternative options I rejected were:

i) stick with MM links
ii) do something 'clever' to retrieve the URLs from MM

Rejected i) because the timing problem where the infra repo gets
updated before MM has the updated repodata checksums is just too
much of a problem; whenever that happens, dnf will refuse to use
the metadata from the infra repo and go pull it from an external
mirror, which can wind up timing out.

Rejected ii) because it seemed too fancy and not really any more
robust than just doing this and adapting it if Things Change In
Future (TM).

openQA tests for the Fedora distribution

This repository contains tests and images for testing Fedora 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

For the present, issues (and pull requests - 'diffs') are tracked in Fedora QA Phabricator. You can open issues against the os-autoinst-distri-fedora project here. See the QA Phabricator wiki page for detailed instructions on filing issues and diffs. Note that this repository does not use the 'gitflow' system, so the main development branch is master: please branch from master and submit diffs against it. This is not a Python repository and has no tests or linting, so you do not need to follow the instructions regarding virtualenv.

Test development

See official documentation on:

See this example repo on how tests should be structured.

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 Fedora and waiting for Fedora 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. Select test from phabricator page.
  2. 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.
  3. Set correct variables (so that all test parts you have made are executed) in WebUI -> Test suites.
  4. Link your newly created Test suite to medium type in WebUI -> Job groups.
  5. Run test (see openqa_fedora_tools repository).
  6. Create needles (images) by using interactive mode and needles editor in WebUI.
  7. Add new Job template and Test suite into templates file (and templates-updates, if the test is applicable to the update testing workflow)
  8. Add new Test suite and Test case into conf_test_suites.py file in fedora_openqa repository.
  9. Open differential request via phabricator, set os-autoinst-disti-fedora as a project and repository.
  10. Open differential request for fedora_openqa change if necessary.
  11. Mark your test in phabricator page as done.

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.
