Hmm... ;)

There are lots of other tests/*-test.c files, including the series you
replied to. I've tweaked your original patch so that it outputs:
$ make check-qtest-ppc64 V=1
[...]
TEST: tests/spapr-phb-test... (pid=3080)
/ppc64/spapr-phb/device: OK
PASS: tests/spapr-phb-test
"/spapr-phb/device" is the name of the unit test supplied to
qtest_add_func(), which then prepends the architecture for uniqueness.
Without calling it, there is no indication that the test was successful.
Individual tests reading/writing registers etc. will need the
qemu-system-ppc64 process running, so g_test_run() needs to go before
qtest_end(). Or if you want to launch it multiple times (e.g. with
different parameters) place it into the test function like originally.
Your test did not pass on qemu.git or qom-next - I picked up the
corresponding fix from ppc-next to reallow -device spapr-pci-host-bridge.
Further the patch was missing a line for gcov to pick up the .o file:
