+Subject: [PATCH] Remove unittest.makeSuite, gone from Python 3.13
+
+See https://docs.python.org/3.13/whatsnew/3.13.html
+
+"""
+Removed the following unittest functions, deprecated in Python 3.11:
+
+    unittest.findTestCases()
+    unittest.makeSuite()
+    unittest.getTestCaseNames()
+"""
+
+The removed call does not seem to have any effect when the file is executed
+directly, run trough unittest discover or pytest.
