I see this sometimes on my local tests

Not each test is failing. On production I don't have seen that problem. We need to investigate why in this order of tests the problem occures and likly improve a test.

Hey @ReimarBauer , I could not reproduce the issue. Can you please help with this.

When I ran pytest test_mscolab.py I got these results Screenshot 2024-11-30 144816 Screenshot 2024-11-30 144842

just a follow up mention @ReimarBauer can you look into this please!

This error happens randomly in parallel testing. It is not easy to catch.

Dec 03 '24 08:12 ReimarBauer

Modify the service_cache method to check if the directory exists before trying to list its files.

import os

def service_cache(self): if os.path.exists(self.wms_cache) and os.path.isdir(self.wms_cache): files = [os.path.join(self.wms_cache, f) for f in os.listdir(self.wms_cache)] # proceed with your logic here else: print(f"Directory {self.wms_cache} does not exist.")

That is not the solution because the problem seems only to occure in the tests on parallel testing. I believe we need to find the test which is the reason for this.

We have to set wms_cache https://github.com/Open-MSS/MSS/blob/stable/tests/_test_msui/test_wms_control.py#L500

similiar as here https://github.com/Open-MSS/MSS/blob/stable/tests/_test_msui/test_wms_control.py#L69

On the MBP I got today

Failed: An unhandled message box popped up during your test!
E       PyQt5.QtWidgets.QMessageBox.critical(): [call(<mslib.msui.wms_control.HSecWMSControlWidget object at 0x34be62950>, 'Web Map Service', "ERROR: Cannot delete file '/Users/reimarbauer/Library/Caches/msui/wms_cache/6a69a349092204e79ecfb3fabe12998a.png'. (<class 'FileNotFoundError'>: [Errno 2] No such file or directory: '/Users/reimarbauer/Library/Caches/msui/wms_cache/6a69a349092204e79ecfb3fabe12998a.png')")]

that looks like a test does not use a tmp dir. It is not clear yet if it is the same problem.

it is maybe fixed by https://github.com/Open-MSS/MSS/pull/2829

reopen when not

test_activate_operation_updates_active_users needs a review

Modify the service_cache method to check if the directory exists before trying to list its files.
