As I searched the makeSuite function is deprecated and removed from python 3.13 and the eq has changed so it's not compatible with python 3.13

[daskol]

It seems that there are two different issues related to new Python 3.13 release. The first one is deprecation of some unittest routes (see python/cpython#104836). The second one is related to assertEqual assertion and it seems to be a bug in dataclasses (see python/cpython#128294). The former is easy to fix but the latter seems serious issue.
