inspect.getargspec is deprecated in 3.11. Use getfullargspec instead.
It returns FullArgSpec(args, varargs, varkw, defaults, kwonlyargs, kwonlydefaults, annotations) instead of ArgSpec(args, varargs, keywords, defaults)

It's time to drop inspect.getargspec and even inspect.getfullargspec. See microsoft/knack#275 (comment).
A previous attempt was made by #24111.

The MockExtension does not mock all attribution in Extension.

It is a Captured log call, it does not affect the test result.
The 3.11 test fails so I notice this error.
I've reverted this change.
I don't know cause of this error, I'll create a new PR if I can figure it out.

Prevent AttributeError: <MagicMock id='2694374960976'> does not have the attribute '__version__' error.
Not sure why it breaks in 3.11.
It seems mock can only overwrite some of the magic functions in Python and __version__ is not supported, see

This test fails in Python 3.11:
E AttributeError: <MagicMock id='2148541021584'> does not have the attribute '__version__'
C:\Users\xxx\AppData\Local\Programs\Python\Python311\Lib\unittest\mock.py:1416: AttributeError
I found a similar issue scikit-hep/pyhf#2143. Switching to mock.patch.object(azure.cli.core, '__version__', "2.7.0") indeed solves this error. This makes me wondering if the import logic with string 'azure.cli.core' has been broken in Python 3.11.
After further debugging mock.py source code, I noticed unittest.mock._patch.getter in Python 3.10 is able to get azure.cli.core module, but unittest.mock._patch.getter in Python 3.11 is not able to do that - it returns a MagicMock. According to https://docs.python.org/3/library/unittest.mock.html#id3:
The only exceptions are magic methods and attributes (those that have leading and trailing double underscores). Mock doesn’t create these but instead raises an AttributeError. This is because the interpreter will often implicitly request these methods, and gets very confused to get a new Mock object when it expects a magic method. If you need magic method support see magic methods.
Git blaming mock.py shows unittest.mock._get_target's logic has been changed to use pkgutil.resolve_name in Python 3.11 (python/cpython#18544), but pkgutil.resolve_name's functionality is broken by

Great work, I have never considered that this error is related to @mock.patch('pkgutil.iter_modules', _mock_iter_modules) .

I figured this out.
The actual cause is @mock.patch('importlib.import_module', _mock_import_lib).
In 3.10, mock use its own _import(target_name), which uses __import__ and getattr, to get the target object. azure.cli.core is returned.
https://github.com/python/cpython/blob/fc382d3dd08709a9dc5000a691d3a74f7b4a99ac/Lib/unittest/mock.py#L1618
In 3.11, it uses pkgutil.resolve_name(target_name) to get target object, which calls importlib.import_module internally.
However, importlib.import_module is patched and always returns mock.MagicMock(), thus a MagicMock() is returned and it does not have __version__ attribution.

Let's keep this conversation open as a TODO item. I feel there should be a way to patch pkgutil.resolve_name more elegantly.

*, ** arguments may not necessarily be called arg or kwargs. It is safer to check whether its kind is VAR_POSITIONAL or VAR_KEYWORD.
Maybe getfullargspec is an easier drop-in replacement.

Is it possible to totally remove this signature check as our callback now only has one format?

Rollback to inspect.getfullargspec, for using signature to achieve same result is obscure.
