CI fails sequentially. Maybe due to this?

This line turns off the logger buffering feature: https://github.com/ryanofsky/bitcoin/blob/55059269fe7379912b315a80f3a1a17b33a3e23d/src/logging.cpp#L68
so that https://github.com/ryanofsky/bitcoin/blob/55059269fe7379912b315a80f3a1a17b33a3e23d/src/logging.cpp#L267 is false and the logger callbacks are called
I have tried to run locally src/test/test_bitcoin --log_level=all --run_test=getarg_tests and it passes. However, src/test/test_bitcoin does not pass for me so you are right and it can be reasonably reproduced. Also as one may expect variable s is empty (https://github.com/ryanofsky/bitcoin/blob/55059269fe7379912b315a80f3a1a17b33a3e23d/src/test/getarg_tests.cpp#L307).

So the error is because of this line https://github.com/ryanofsky/bitcoin/blob/55059269fe7379912b315a80f3a1a17b33a3e23d/src/logging.cpp#L53 as m_print_to_file is true sometimes so the callback is not called.

kiminuo@1ca557e might actually fix the issue but I'm not sure what you would say about the change. Anyway, I don't really know about a different solution so either that or closing #24375.
This uncovers that working with static variables is hard :(

re: #24375 (comment)
I wasn't really sure how to reproduce this but now I tried switching to the BasicTestingSetup fixture to see if that fixes it

I used src/test/test_bitcoin --run_test=getarg_tests,fs_tests to reproduce the issue.

My understanding is that Logger instance is shared between tests. So then fs_tests and getarg_tests interfere with each other because the BasicTestingSetup fixture sets a file name, then getarg_tests/logargs and its LogInstance().StartLogging(); does not turn off buffering of log messages and then the callback in logargs is not actually called.

@ryanofsky Do you feel like switching to BasicTestingSetup is a good enough result for now or do you feel like it would be actually fruitful to remove the dependency on BasicTestingSetup?
I think it is reasonable to reserve the later for a future PR as it seems it requires more changes.

I don't think there's a problem with depending on BasicTestingSetup here, but maybe I am coming at this from different perspective. I think global variables are almost always a problem, but test fixtures are only sometimes a problem (#22155 (comment) was a place where I previously objected to using test fixtures unnecessarily).
