pytest中的参数化测试，对不同的测试函数有不同的标记

import pytest

@pytest.mark.parametrize("num, expected", [
    (1, 2),
    (2, 3),
])
def test_increment(num, expected):
    assert num + 1 == expected

@pytest.mark.parametrize("num, expected", [
    (2, 4),
    (3, 9),
])
@pytest.mark.slow
def test_square(num, expected):
    assert num * num == expected

pytest -k slow

pytest -m slow
