使用unittest.mock.patch断言pathlib.Path.touch特定调用失败的问题求助

我在使用pathlib.Path.touch创建文件，想用unittest.mock.patch装饰器在单元测试中断言相关调用，但是遇到了问题。以下是我的代码和测试情况：

sessions.py #

from pathlib import Path

def generate_folders(paths: list):
    for p in paths:
        p.mkdir()
        Path(p / "output").mkdir()
        Path(p / "output" / "output_file").touch()
        Path(p / "session_file").touch()

测试代码 #

import unittest
from unittest.mock import patch
from pathlib import Path
import sessions

class TestSessionsCreation(unittest.TestCase):
    @patch("os.mkdir")
    @patch("pathlib.Path.touch")
    def test_folder_creation(self, touch_mock, mkdir_mock):
        tags = ["concepts", "models", "animations", "vfx", "sfx", "vo", "music"]
        paths = sessions.generate_paths(category="character", name="player", tags=tags)
        sessions.generate_folders(paths)
        for p in paths:
            mkdir_mock.assert_any_call(p, 511)
            mkdir_mock.assert_any_call(p / "output", 511)
            touch_mock.assert_any_call(Path(p / "output" / "output_file"), 511)
            touch_mock.assert_any_call(Path(p / "session_file"), 511)

我可以正常断言os.mkdir的文件夹创建，也能确认pathlib.Path.touch被调用过，但用assert_any_call()断言特定调用时总是失败。测试抛出的错误如下：

ssF...

让我费解的是，我用pdb调试确认过方法的输入值是完全一致的，但测试还是失败。我也反复检查了os.mkdir和pathlib.Path.touch的装饰器顺序是正确的。另外我也尝试用with语句来patchtouch，测试还是不通过。我搞不清这是代码的问题还是测试的问题，想请教大家有没有什么提示？我哪里做错了？漏掉了什么？
