Gio.TestDBus.prototype.down
function down(): void { // Gjs wrapper for g_test_dbus_down() }
Stop the session bus started by Gio.TestDBus.prototype.up.
This will wait for the singleton returned by Gio.bus_get or Gio.bus_get_sync is destroyed. This is done to ensure that the next unit test won't get a leaked singleton from this test.
