1. 创建test_project 目录

test_project/sub/test_sub.py

def test_baidu(test_url):print(f'sub ={test_url}')

test_project/conftest.py  设置钩子函数  只对当前目录 和子目录起作用

import pytest
#设置测试钩子函数
@pytest.fixture()
def test_url():return  "https://www.baidu.com"

test_project/test_demo.py

def test_baidu(test_url):print(test_url)

运行 

 pytest -s -v ./test_project

或 main 运行

import pytestif __name__=='__main__':#pytest.main(['-s','./fixture'])#pytest.main(['-v', './fixture','--junit-xml=./report/log.xml'])#pytest.main(['-v', './fixture', '--pastebin=all'])pytest.main(['-v','-s' ,'./test_project', '--pastebin=all'])
