1) additional qemu tests for ami, vmdk, vhd, and openstack image types
2) new type of systemd-nspawn tests for tar, ext4, and parititioned disk
types
the systemd-nspawn tests use loopback network interface directly from
the host so it is necessary to tweak the settings of its SSH server.
This is done in a "script" stage using simple "sed" command.
The tests works by executing osbuild with predefined pipeline. Then the
image boots and the testing script creates SSH connection to the running
VM. If everything goes fine `systemctl is-system-running` is executed
with result `running` and the test case passed.
The JSON definition of the test case contains also a blueprint that
should generate the desired pipeline, but it didn't work for me, so I'm
including it for future use from the golang unit tests.
Introduce the `distro` package, which contains an interface for OS
implementations. Its main purpose is to convert a blueprint to a
distro-specific pipeline.
Also introduce the `distro/fedora30` package. It is the first
implementation of the distro interface. Most of its code has been copied
with minimal modifications from the blueprint package.
The `blueprint` package is now back to serving a single purpose:
representing a weldr blueprint. It does not depend on the `pipeline`
package anymore.
Change osbuild-composer and osbuild-pipeline to use the new API,
hard-coding "fedora-30". This looks a bit weird now, but is the same
behavior as before.
All test cases now also take an "distro" key in the "compose" object.
These tests (will) test more than just image-info: they'll take a
blueprint, verify that `osbuild-pipeline` generates the correct
pipeline, run osbuild with that pipeline and verify that the resulting
image has the expected image-info output.
This change only includes the latter half (i.e., only moves the already
existing tests).
Also drop python's unittest. It was hard to control output (important
for quickly spotting failures and to make travis happy). This introduces
test/run, which runs all test cases in test/cases or the ones given on
the command line.
When a failure occurs, it prints a diff of the actual and the expected
image info.
