An issue I just discovered

testing_issue.py

import itertools

import pytest


def sum(a, b):
    return a + b


def minimum(*numbers):
    return min(numbers)


# Tests

@pytest.mark.parametrize("a, b", itertools.permutations([3, 4, 5], 2))
class TestF:

    def test_sum(self, a, b):
        assert sum(a, b) == a + b

    # This test will be skipped, why?
    def test_minimum(self, a, b):
        assert minimum(a, b) == min(a, b)
