pytest - Pytest 在失败报告中显示参数值

Question

有时会pytest -vvv在故障报告顶部显示参数值，如下所示，但有时不会。当它没有自动发生时，如何让它显示参数值？

=================================================================== FAILURES ===================================================================
_____________________________________________________________ test_person[person0] _____________________________________________________________

person = Person(name='Alice', hobbies=[Hobby(title='hacking')])

    @pytest.mark.parametrize("person", PERSONS)
    def test_person(person):
>       assert person == 'foo'
E       AssertionError: assert Person(name='Alice', hobbies=[Hobby(title='hacking')]) == 'foo'

../../tmp/ids.py:25: AssertionError
