Dictionaries and sets

Dictionaries are probably one of the most used data structures in Python, so, unsurprisingly, pytest has specialized representation for them:

_______________________ test_starting_health ________________________

    def test_starting_health():
        expected = {'warrior': 85, 'sorcerer': 50}
>       assert get_classes_starting_health() == expected
E       AssertionError: assert {'knight': 95...'warrior': 85} == {'sorcerer': 50, 'warrior': 85}
E         Omitting 1 identical items, use -vv to show
E         Differing items:
E         {'sorcerer': 55} != {'sorcerer': 50}
E         Left contains more items:
E         {'knight': 95}
E         Use -v to get the full diff

Sets also have similar output:

________________________ test_player_classes ________________________

    def test_player_classes():
>       assert get_player_classes() == {'warrior', 'sorcerer'}
E       AssertionError: assert {'knight', 's...r', 'warrior'} == {'sorcerer', 'warrior'}
E         Extra items in the left set:
E         'knight'
E         Use -v to get the full diff

As with lists, there are also -v and -vv options for displaying more detailed output.
