import pytest


@pytest.fixture()
def first():
    print('==========step1==========')


@pytest.fixture()
def second():
    print('==========step2==========')


@pytest.fixture()
def three():
    print('==========step3==========')


def test_01(first, second, three):
    print('===========test_01=======')


def test_02(second, first, three):
    print('===========test_01=======')


def test_03(second, first):
    print('===========test_01=======')

执行结果如下：
