Running a full test class fails when each test succeeds
Describe the bug
There is a strange interaction going on between OpenPyxl and Pyfakefs via Pandas. I can read and write DataFrames as normal using the fake filesystem and pd.read_excel et al just fine when the tests are run in isolation. However, when I run the entire test class, one test will succeed and the rest will fail.
I have already used the solution in https://github.com/pytest-dev/pyfakefs/discussions/716 to remove the use of LXML to read and write the Excel files.
How To Reproduce
import os
os.environ['OPENPYXL_LXML'] = 'False'
import io
import pandas as pd
from pyfakefs.fake_filesystem_unittest import TestCase
class BugTest(TestCase):
def setUp(self) -> None:
self.setUpPyfakefs()
def test_a(self):
df = pd.DataFrame({})
df.to_excel('/testa.xlsx', index=False)
def test_b(self):
df = pd.DataFrame({})
df.to_excel('/testb.xlsx', index=False)
def test_c(self):
df = pd.DataFrame({})
df.to_excel('/testc.xlsx', index=False)
test_a passes, test_b and test_c fail with essentially the same output:
./test_src_load_research_population_data_prep.py::BugTest::test_b Failed with Error: [Errno 2] No such file or directory in the fake filesystem: '/tmp/openpyxl.ui35n6ko'

Thanks for the report!
I could not reproduce this under Windows (where I work at the moment), so I guess there is some Posix-specific code involved.
It may also be that is is version-specific. In your conda list, there is no pandas listed - didn't you install it via conda? Which version did you use?
We're on pandas 1.5.3. It's installed through pip for some reason, although I don't know why.
Thanks - downgrading to 1.5.3 didn't change the outcome. I will have a closer look somewhere in the next days.
I still cannot reproduce the problem. I tested your example in the CI, and it runs fine in Ubuntu, MacOS and Windows, under Python 3.8 to 3.12. I had installed pandas 1.5.3 and openpyxl 3.0.10, and ran it using pytest (how are you running the test?).
The environment is not the same, as I used a different Linux, the packages had been installed via pip instead of conda, and I did not install the bunch of other packages in your environment, but none of these should make a difference, so I'm a bit lost... I can see from the stacktrace that some temp file in the second test is not in the fake filesystem, so it had likely been created in the real filesystem and the patching did not work at some point, but at the moment I have no idea why.
As long as I'm not able to reproduce this I cannot promise any fix. I will let you know if I can think of some additional tests you can do to clarify this.
@JonathanDCohen - I have tried a couple of times to reproduce or understand this, but without success. Is this still a problem for you? If yes, could you reproduce this on any other system?
I had recently a number of issues related to the dynamic patcher cleanup. You could check if your problem is also related to this by switching off the dynamic patcher:
def setUp(self) -> None:
self.setUpPyfakefs(use_dynamic_patch=False)
You need to update pyfakefs to the latest version for this, as this option was not available in the version you used.
If either all tests pass, or no test passes, the problem is indeed related to the dynamic patcher.
I'll give it a shot!

I just published a new release - please use this if you are going to re-test the problem.
I did not test it again, I got pulled along to other pressing issues in the project. I'll let you know when I can but it's low priority for me right now.
