A good way to compare the expected queryset with the results of the response #9550

I have a question when comparing the response(.data) and queryset object. As an example, let's say there is a class called Dog and there is logic in View to get a list of hungry dogs. The two values that I want to compare with assertEqual, response and expected_response, are of different types.
In the case of response.data, Serializer is applied, so when it's in dict form, I want to compare it with Queryset type expected_response.
number 2 example. But I'm not sure if the two methods are good in comparison.

Personally, I like to create a single entry to test the retrieve part of my viewset, and check the full payload, status code, etc... But in case of list/filter endpoints, I would only check the ID / name attribute to make sure the ones I expect to see are present, not the full payload. With your example, create a hungry dog, create a not hungry dog, call the endpoint with |

That's a good thing to say 💪 I was a little uncomfortable used the list comprehension to get only the id value from this part. |
