Public bug reported:
[Impact]
Spurious warnings in tests since Python 3.12, might cause tests to fail when
asserting that stderr is empty.
[Test plan]
Run the update-manager autopkgtest and see no such warning.
[Where problems could occur]
There is no regression potential basically. The code creating the warning in
Python 3.12+ looks like:
def _addDuration(self, result, elapsed):
try:
addDuration = result.addDuration
except AttributeError:
warnings.warn("TestResult has no addDuration method",
RuntimeWarning, 1)
else:
addDuration(self, elapsed)
that is, if the addDuration method does not exist, it logs a warning and
does nothing else. By adding the addDuration method, the warning is not
printed.
The addDuration method adds the execution time of the test to the test
result, but nose's test results does not track that, so meh.
