when testing downstream snapshots this makes sure that
lorax-composer and composer-cli are coming from the host OS.
We also make 100% sure that there are no other repositories inside
the VM other than what has been configured on the host!
Make it possible to override where repo files are copied from by
defining the REPOS_DIR variable. By default the value is
/etc/yum.repos.d
to help with running the tests by hand on downstream snapshots.
In that scenario we want TEST_OS/VM_IMAGE to look as closely as
possibly like the snapshot that we'd like to test.
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.
