- avoids having to modify them in the first place so less changes
to the SUT
- will help with transition to osbuild-composer backend
- each test which needs a blueprint either declares it on its own
(some already do this) or may use a shared blueprints from the
tests lib dir
Previously it was looping, waiting for FINISHED|FAILED but was not
actually failing the test if the compose failed to build.
This adds a function to check the status of the compose and calls it
after each compose.
Beakerlib upstream can't do this yet, but might at some point:
https://github.com/beakerlib/beakerlib/issues/42
This is only enabled in combination with the `--sit` option of the
`test/check-*` scripts. It leaves the system in exacly the state it was
in when an assertion failed. Finishing the test run would run cleanup as
well (such as deleting created images). It also takes longer.
We were checking for composer's FINISHED status only, which meant that
when a compose failed, the test ran until it timed out.
Check for failed as well. Also, always time out after 30 minutes.
