Public bug reported:
The new SessionBackend tests talk to the real system services (like
logind), which means the result depends on where the test is ran. They
pass on CI because the tests are effectively skipped if the service
isn't available. On the other hand it fails for me (see below), because
my laptop does not hibernate and the answer from logind is "na", not
"no":
$> qdbus --system org.freedesktop.login1 /org/freedesktop/login1
org.freedesktop.login1.Manager.CanHibernate
na
The tests need to talk to a mock service (on the session bus) that's
launched along the test using dbus-test-runner. Use
QDBusConnection::SM_BUSNAME() to switch the implementation between
system and session buses (see e.g. AccountsService tests for examples).
