**Describe the bug** Attempting to package `2.0.0b7`, I run into the problem that `tests/test_entrypoint.py::test_gbk` needs `tests/resources/gbk_test.bib`, which is not included in the tarball. I'm working around it by skipping that particular test, but the policy seems inconsistent -- either releases aren't meant to include tests (in which case the presence of the `tests` directory is weird) or they should include the resources necessary to run them (in which case `gbk_test.bib`'s absence is weird) **Reproducing** Version: `2.0.0.b7` Code: ```bash wget https://files.pythonhosted.org/packages/source/b/bibtexparser/bibtexparser-2.0.0b7.tar.gz tar xvf bibtexparser-2.0.0b7.tar.gz cd bibtexparser-2.0.0b7/ python -m pytest .... ======================================== short test summary info ========================================= FAILED tests/test_entrypoint.py::test_gbk - FileNotFoundError: [Errno 2] No such file or directory: 'tests/resources/gbk_test.bib' ====================================== 1 failed, 47 passed in 0.79s ====================================== ``` **Workaround** Invoking pytest instead as ``` python -m pytest -k 'not (test_entrypoint.py and test_gbk)' ``` which skips the broken test. **Remaining Questions (Optional)** Please tick all that apply: - [ ] I would be willing to contribute a PR to fix this issue. - [ ] This issue is a blocker, I'd be grateful for an early fix.
