One more event may be still in pipe... I think, better is just do self.vm.wait_event(name='BLOCK_JOB_COMPLETED), and ignore JOB_STATUS_CHANGE events. > + > + result = self.vm.qmp('block-stream', device='drive0', > + job_id='stream-top') > + self.assert_qmp(result, 'return', {}) > + > + self.wait_until_completed(drive='stream-top') > + self.vm.shutdown() > + > + top = json.loads(qemu_img_pipe('info', '--output=json', test_img)) > + mid = json.loads(qemu_img_pipe('info', '--output=json', mid_img)) > + base = json.loads(qemu_img_pipe('info', '--output=json', backing_img)) > + > + self.assertEqual(mid['actual-size'], base['actual-size']) > + self.assertLess(top['actual-size'], mid['actual-size']) > + self.assertLess(self.test_img_init_size, top['actual-size']) I think last assertion is covered by previous two. And I'm still unsure about using actual-size. Direct checking number of compressed clusters by qemu-img check maybe better. > + > if __name__ == '__main__': > iotests.main(supported_fmts=['qcow2', 'qed'], > supported_protocols=['file']) > diff --git a/tests/qemu-iotests/030.out b/tests/qemu-iotests/030.out > index 6d9bee1..af8dac1 100644 > --- a/tests/qemu-iotests/030.out > +++ b/tests/qemu-iotests/030.out > @@ -1,5 +1,5 @@ > -........................... > +............................ > ---------------------------------------------------------------------- > -Ran 27 tests > +Ran 28 tests > > OK >
