nose-py3 is a Python 3 fork of the original nose testing library, which extends unittest to make testing easier. The current version is 1.9.0, but it is largely superseded by nose2 and pytest. This fork was created to provide a Python 3 compatible version, but development is minimal and the original nose project recommends alternatives. Release cadence is low; no recent updates.

Known issues
deprecatednose-py3 is a fork of nose, which is no longer actively maintained. The original nose project recommends migrating to nose2 or pytest.
fix
Use pytest or nose2 instead.
affects: all
gotchanose-py3's plugin system is incompatible with some third-party plugins written for nose (Python 2). These plugins may not work correctly.
fix
Check plugin compatibility or use pytest with pytest-plugins.
affects: all
gotchanose-py3 may not support newer Python 3 features like type hints and asyncio tests. It is best suited for simple unit tests.
fix
For modern testing, switch to pytest with unittest support.
