我想在www.example.com上设置一个fixture，并与我所有的测试共享它，但是，当我在下面的最小示例上运行pytest时，我遇到了以下错误：conftest.py and share it with all my tests. However, I run into the following error when running pytest on the following minimal example:

ERROR at setup of test_test 
Fixture "pytest_runtest_setup" called directly. Fixtures are not meant to be called directly,
but are created automatically when test functions request them as parameters.

conftest.py

import pytest
import os

@pytest.fixture
def pytest_runtest_setup():
    print("hello ? ---------------------------------")

test.py

import pytest

def test_test():
    assert True

pytest.ini

[pytest]
addopts = -rA -v -p no:faulthandler -W ignore::DeprecationWarning

Pytest随pytest test.py一起推出
fixture函数在任何地方都不能被直接调用，甚至在示例测试中也不能使用它，那么pytest为什么要抛出这个函数，以及如何在www.example.com中声明和使用fixtureconftest.py?
环境：

• Python 3.8.3语言
• 高温试验-6.1.2
