+Subject: [PATCH] Fix assertion in TestCheckParseValues::test_warns_bad_type
+
+Fix the assertion in TestCheckParseValues::test_warns_bad_type
+to use `.assert_called_with()` rather than non-existing `.called_with()`
+method.  The latter is wrongly interpreted as calling a mocked method
+in Python < 3.12, and therefore does not test anything at all.  Starting
+with Python 3.12, it results in an error:
+
+    AttributeError: 'called_with' is not a valid assertion. Use a spec for the mock if 'called_with' is meant to be an attribute.
+
+Fixing the call also revealed that the assertion was incorrect, so I've
+updated it to match the current call.
