Move the last remaining test into the correct subdir. With this done,
all our tests run in one of the 3 groups:
* `make test-src`
Run tests against the source-code, including linters.
* `make test-mod`
Run unit-tests on the individual python modules. This needs no
special permissions (unless noted in each test) or runtime
environments. It is meant to be fast and easy to run in all
circumstances.
* `make test-run`
Run tests that execute the osbuild pipeline. This requires
superuser privileges and will likely take a while. Furthermore,
this might produce large artifacts.
Move the stage-tests over to the new test-infrastructure. This moves
the test invocation into `./test/run/test_stages.py`, so it is invoked
as part of the runtime-tests. Secondly, the test-data is stored in
./test/data/stages/ so the path is relative to
TestBase.locate_test_data().
While at it, this also drops the dynamic class modifications and instead
uses subTest(). This simplifies the code quite a bit and avoids
dynamically creating python code.
This moves the `sources_tests` into ./test/data/sources/ and makes the
entire test use `locate_test_data()` to get relative paths for their
accesses.
This further improves our test cases to support running from
installments rather than local checkouts. We need access to ./test/data
guarded, so we can install packages and still have the tests access the
correct paths.
This also adjusts the HTTP-Server we use in the test to serve data
relative to a path it is handed. I now chose `./test/data`, which will
easily allow us to re-use the same HTTP-Server in the future for other
tests that require it.
Add a new trivial runtime-test which simply runs a no-op pipeline. This
is a fast, trivial test that simply verifies osbuild is properly setup
and accessible.
Remove the explicit no-op test from the CI, now that the test-suite has
it as well.
The idea is that source can themselves spawn other modules, esp.
new secrets modules. For this they need to know the library dir,
aka 'libdir' throughout the osbuild source. Therefore change the
SourceServer to directly get the library directory instead of
just the sub-directory to the sources. Then pass the library
directory to via the JSON API to the source.
Adjust all usage of the SourceServer, including the tests.
