如何使用不同进程中的fixture调用测试

import pytest
from multiprocessing import Process, Manager

# 定义一个需要在不同进程中共享的fixture
@pytest.fixture(scope="session")
def shared_data():
    with Manager() as manager:
        data = manager.dict()
        yield data

# 测试函数
def test_process_1(shared_data):
    shared_data['process_1'] = 'Data from process 1'
    print(f"Process 1: {shared_data}")

def test_process_2(shared_data):
    shared_data['process_2'] = 'Data from process 2'
    print(f"Process 2: {shared_data}")

# 运行测试的函数
def run_test(test_func, shared_data):
    test_func(shared_data)

if __name__ == "__main__":
    manager = Manager()
    shared_data = manager.dict()

    p1 = Process(target=run_test, args=(test_process_1, shared_data))
    p2 = Process(target=run_test, args=(test_process_2, shared_data))

    p1.start()
    p2.start()

    p1.join()
    p2.join()

    print(f"Final shared data: {shared_data}")
