Note: use podman-docker to avoid changing tests too much. This
is also what we have on the RHEL branches.
There's no service to be started/restarted so remove everything
related to docker service.
Commit 4783f6562f introduced the assumption that beakerlib is already
installed in non-RHEL images. As the test script runs without `set -e`,
this hasn't been noticed as the test silently succeeds.
Go back to installing beakerlib everywhere.
Allows to run the tests on multiple operating systems and on the
infrastructure that the Cockpit team maintains.
`make vm` downloads one of Cockpit's test images (override which one
with TEST_OS) and installs rpms build from the local checkout of lorax.
The resulting image is placed in `test/images/$TEST_OS`.
TEST_OS can be set to any of Cockpit's supported images (default:
fedora-30).
Run `make check-vm` to run the CLI checks in the VM. The bulk of the
work is done in `test/check-cli`, which uses Cockpit's `bots` library to
start the VM and run the script in it.
Also included is a `test/run` script, which is the entrypoint for
Cockpit's test infrastructure.
