Good, that's partial success. :-)

Sure, in-process tests are great if you can get them working, because
they are simpler (more reliable) + it's much easier to debug if they
fail.

Hmm, so far you tried out of process + SAL_USE_VCLPLUGIN=svp and
in-process + --headless.

Try experimenting with the in-process + SAL_USE_VCLPLUGIN=svp
combination, perhaps that would give you what you need.

Be aware that in case of in-process tests your test code is running on
the main thread, so if you depend on any idles, you need to manually
spin the main loop with Scheduler::ProcessEventsToIdle() (vs out of
process tests, where this is done for you automatically).
