Comment (by s.shanabrook@…):

 I am testing a post_save signal, and so I need to make sure it doesn't
 save a model recursively. I save only one field using `update_fields`.
 What would you say is the proper way to test something like this? Is there
 a better method than re-retrieving the object from the database to make
 sure it saved the field?
