getargspec gone in Python 3.11?

[Hal Murray]

I have a system using Python 3.11

It says:

======================================================================
ERROR: test_packetize (__main__.NtpqRvInfoStats.test_packetize)
Test ntp.util.packetize by coqtavoric gavage and scatology.
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/murray/ntpsec/play/ntp4/main/tests/pylib/test_util.py", line

    if "msg" in inspect.getargspec(classy.assertEqual).args:
                ^^^^^^^^^^^^^^^^^^
AttributeError: module 'inspect' has no attribute 'getargspec'

It worked with Python 3.10
