As of now the assertQueryEqual method
[[https://github.com/django/django/blob/04ad0f26ba4b8c79dc311e1789457e0c4d1b8832/django/test/testcases.py#L1240-L1241|ueses
counters to compare unordered Querysets]], in the standard unittest
package there is already such method called
[[https://docs.python.org/3/library/unittest.html?highlight=assertcountequal#unittest.TestCase.assertCountEqual|assertCountEqual]],
which also has better output-formatting capability.

{{{#!python
self.assertCountEqual(items, values, msg=msg)
}}}

Using data from current test it will output:

{{{
Element counts were not equal:
First has 0, Second has 1: 'Extra Person'
}}}
