   (__main__.Test.test) ... /opt/hostedtoolcache/Python/3.12.0-alpha.7/x64/lib/python3.12/unittest/case.py:580: RuntimeWarning: TestResult has no addDuration method\n  warnings.warn("TestResult has no addDuration method",\nok\n\n----------------------------------------------------------------------\nRan 1 test in 0.001s\n\nOK\n'
   

   Seems related to: python/cpython#12271.

   Without getting into deep analysys: the test seems to fail because unittest.TestCase class in python 3.12 has a new addDuration method. I imagine nose subclasses unittest.TestCase and extends it in some way. Python 3.12's unittest module is complaining (warning) that your custom sublcass does not provide an addDuration method. Defining an addDuration method will remove the warning and fix the failure.

      .. method:: addDuration(test, elapsed)
   
         Called when the test case finishes.  *elapsed* is the time represented in
         seconds, and it includes the execution of cleanup functions.

   My thanks to both of you for running this down and providing the breadcrumbs for me to understand what was happening. I've just merged @cclauss's fix and will make sure to cite him in the changelog under py3.12 compatibility.
