The deprecated unittest aliases were removed in python/cpython#28268 in Python 3.11 . Something like change from below could be used

Could you please elaborate more about this issue clearly?

[tirkarthi]

The method assertDictContainsSubset from unittest.TestCase was deprecated and removed in Python 3.11 . So running these tests in Python 3.11 will give AttributeError.

Recent commit 010e94d should have fixed this and would be released in upcoming version.
