`test_no_user_warning` assumes pip is available
I'm packaging your module as an rpm package so I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.
python3 -sBm build -w --no-isolation- because I'm calling
buildwith--no-isolationI'm using during all processes only locally installed modules - install .whl file in </install/prefix> using
installermodule - run pytest with $PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>
- build is performed in env which is
cut off from access to the public network(pytest is executed with-m "not network")
Here is pytest output:
+ PYTHONPATH=/home/tkloczko/rpmbuild/BUILDROOT/python-astroid-3.1.0-2.fc36.x86_64/usr/lib64/python3.9/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-astroid-3.1.0-2.fc36.x86_64/usr/lib/python3.9/site-packages
