Performing only a light (yet comprehensive) subset of the test suite.
If you want a more complete test, try passing the --heavy flag to this script
(or set the 'heavy' parameter in case you are using tables.test() call).
The whole suite will take more than 4 hours to complete on a relatively
modern CPU and around 512 MB of main memory.

According to https://docs.python.org/3.13/whatsnew/3.13.html:

Removed the following unittest functions, deprecated in Python 3.11:
- unittest.findTestCases()
- unittest.makeSuite()
- unittest.getTestCaseNames()

For all our attempts to build python-tables with Python 3.13, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/package/python-tables/

Testing and mass rebuild of packages is happening in copr.
You can follow these instructions to test locally in mock if your package builds with Python 3.13:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/

Let us know here if you have any questions.

Python 3.13 is planned to be included in Fedora 41.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.13.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires),
so if this package is required a lot, it's important for us to get it fixed soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work around it on our side.
