same here, you may want to break this test into separate ones since they have
different setups.

Alternatively it may be worth exploring creating a dict that maps
analysis_status to expected status_description then iterating over that dict

i.e.

descriptions = {
  analysis_status.PENDING: 'Pending'
  analysis_status.RUNNING: 'Running'
  ...
}

for status, description in descriptions:
  self.dummy_model.status = status
  self.assertEqual(...)

not a big deal in either case.

+    self.dummy_model.status = analysis_status.ERROR
+    self.assertEqual('Error', self.dummy_model.status_description)
