Using DISTRO_CODE simplifies test case selection and allows to test
different distro than the one test is running on.
This is used to run tests for RHEL 9.0 on F33 or RHEL 8.4
rhel 8.4 tests are added. The configs are based off of those used for
rhel 8.3. The Schutzbot Mockbuild, Base, Image, Integration, and OSTree
tests are added for 8.4. Repo overrides are added for the rhel 8.4 tests
so that the tests use rpmrepo snapshots.
The mockbuild uses the jenkins rhel84-nightly-repo credential to
override the rhel mock template's repos with rhel 8.4 nightly repos.
These repos are stored in a credential because they are internal links.
The image tests and koji tests need a special distro selector since the
rhel-8 test cases are only for rhel 8 versions less than 8.4. The rhel
8.4 tests are named with the rhel-84 pattern whereas the other rhel 8
versions have the rhel-8 pattern.
Also, instead of having only rhel-8 and rhel-8-beta repo configs for the
tests, we now have a specific repo config for each rhel release we test.
The repo is also now pulled from an rpmrepo snapshot. For whichever
distro is being tested, the approriate repo config will be copied to
/etc/osbuild-composer/repositories as rhel-8 and rhel-8-beta since this
is the naming osbuild-composer looks for. For testing purposes, the
rhel-8 and rhel-8-beta repo should be the same since eventually all rhel
releases will go from beta to not beta. The fedora repo overrides are
already done in tools/provision.sh so the rhel override is set there as
well. Currently, only rhel 8.4 requires an override.
Attempt to clarify the structure of our tests. Each test case is now
encapsulated in a script in `test/cases`. Each of these scripts should
be runnable on a pristine machine and be independent of each other. It
is up to the test-orchestractor to decide if they should be run
consequtively instance, or in parallel on separate instances. Each
script can execute several tests and call whatever helper binaries
is desired. However, each case should be assumed to always run as one.
