Nose is incompatible with Python >= 3.10

[cclauss]

nose.tools.assert_equals() will raise an AttributeError on Python >= 3.10

#93 used https://pypi.org/project/nose2pytest to migrate to pytest.

https://pypi.org/project/nose was last updated in 2015.

Thanks.

It's in my todo list to change to pytest, however I had to find the time to reconfigure my local dev env first! This applies to isbntools too.

Anyway, the library can be used with python 3.10!

STATUS: RESOLVED

SOLUTION: Installing 'nose2' instead of the 'nosetests'

I am still having this issue; nosetest runs fine for 3.7, 3.8, and 3.9 but fails for 3.10.

We ran https://pypi.org/project/nose2pytest in pull request #108 so now this repo tests with pytest, not nose.

To run nose in python is this the proble is that module colleciton doesnt have the attribute Callable
You should change the lines of code 541 and 458 in the suite.py file. The correct line to run nose is this
you should change it also on the line 30 of the case.py file
if isinstance(tests, collections.abc.Callable) or isinstance(tests, unittest.TestSuite):
instead of
if isinstance(tests, collections.Callable) or isinstance(tests, unittest.TestSuite):

nose is nolonger supported by py3. You need to reinstall pynose as an alter.
I uninstalled nose, and installed pynose. Then nosetests runs perfectly.
pip install pynose
nosetests
result:

----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK

python version -- 3.10
runs in virtual env.

Running zero tests is probably not testing anything.
