tests failing when resources unavailable after building from Github tarball

[kloczek]

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 build with --no-isolation I'm using during all processes only locally installed modules
• install .whl file in </install/prefix> using installer module
• 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-cssutils-2.11.0-2.fc37.x86_64/usr/lib64/python3.10/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-cssutils-2.11.0-2.fc37.x86_64/usr/lib/python3.10/site-packages
+ /usr/bin/pytest -ra -m 'not network'

[jaraco]

Since this issue is more general than just for jaraco/cssutils, I've moved it to jaraco/skeleton.

I believe the issue you're encountering here is you're not getting the package data (like cssutils/tests/sheets/csscombine-proxy.css). It's the same issue as jaraco/pytest-enabler#9 and jaraco/jaraco.text#5 (comment). These projects depend on setuptools_scm to infer from the git repository which files should be included in the sdist. Since you're not building from an sdist or the git repo, you'll be responsible to supply the metadata to ensure package data is included.

In the case of jaraco.text you manually copy the file. In the case of pytest-enabler, I suggested adding a MANIFEST.in that just includes everything.

Do either of those approaches work to solve this issue in general?
