如何在测试函数之外访问 Pytest 项目

Question

I want to retrive pytest current running test item and then append my function running data into item.user_properties .

I tried to create dummy plugin and impl pytest_runtest_protocol , update running item in side the hook, then access item from plugin from _pytest.config import get_plugin_manager , plugin_manager.get_plugin('dummy').current_running_item but it does not work, get_plugin('dummy') return None

How can I achive this or is there a better way?

# my_package/utl.py
from _pytest.config import get_plugin_manager
def my_requester(url):
    ...
    ...
    manager = get_plugin_manager()
    dummy = manager.get_plugin('dummy')
    item = dummy.current_item
    item.user_properties.append(('requested_url',url))

# conftest.py
import pytest
class Dummy:
    def __init__():
        self.current_item = None
    def pytest_runtest_protocol(self, item, nextitem):
        self.current_item = item

def pytest_configure(config):
    dummy_plugin = Dummy()
    config.pluginmanager.register(dummy_plugin,'dummy')
      

# test_demo.py
import pytest
from my_package.utl import my_requester


def test_a():
    ...
    my_requester('xxxx')

def test_b():
    ...
    my_requester('yyy')

找到了一个解决方案，只需使用单例模式，将测试项设置为单例对象属性，并将函数运行数据附加到该属性
