我一直遵循pytest文档中的教程来创建临时目录https://docs.pytest.org/en/stable/tmpdir.html，当我执行以下代码时，整个documents文件夹的内容都被删除了。
import pytest
import os
@pytest.fixture()
def tmdirmak(tmpdir_factory):
f = tmpdir_factory.mktemp("data")
return f
def test_temp(tmp_path):
d = tmp_path / "sub1"
d.mkdir()
p = d / "tem.txt"
p.write_text("hello")
assert p.read_text() == "hello"
os.system("ls")
此文件保存在我的documents文件夹中，这是我运行命令pytest --basetemp=. -s test_paths.py 的地方，根据文档的说明，这是您更改临时目录的位置的方式。我不希望在/ tmp中创建临时目录，而是希望在代码存在的同一目录中创建临时目录。运行此命令时，我得到以下pytest输出
test_paths.py E

我想回来是为了找到我在documents目录中要删除的所有文件夹和文档！我怀疑，因为pytest通常认为它在/ tmp中，所以它只是在完成后清除该文件夹中的所有内容，包括未创建的内容。如果这是真的，那就是一个可怕的错误。奇怪的是我收到了这些权限错误，但是我的内容还是被删除了。
