问题
I'm having trouble running pytest on my package. I have the following structure...
tree -f

And my conftest.py has the follwoing...
"""
Fixtures for test_tcx2gpx
"""
from pathlib import Path
import pytest
from tcx2gpx.tcx2gpx import TCX2GPX
TCX_DIR = Path(__file__).resolve().parents[1]
TCX_FILE = TCX_DIR / 'resources' / '2019-10-20 12:51:21.0.tcx'
GPX_FILE = TCX_DIR / 'resources' / '2019-10-20 12:51:21.0.gpx'
@pytest.fixture
def tcx_file():
"""
Fixture of TCX file
"""
return TCX2GPX(TCX_FILE)
On running pytest from the top-level I'm informed...
____________________________________________________ ERROR collecting test session ____________________________________________________

Reading around I found a few threads on this (e.g. here) and because I'm working on CI on GitLab I decided to try modifying the PYTHONPATH (as I can put these as part of the script that is executed on GitLab CI execution)...
export PYTHONPATH="$PYTHONPATH:."
python -c "import sys;print(sys.path)"
['', '/mnt/work/python/tcx2gpx', '/home/neil/.virtualenvs/default/lib64/python
36.zip', '/home/neil/.virtualenvs/default/lib64/python3.6', '/home/neil/.virtualenvs/default/lib64/python3.6/lib
-dynload', '/usr/lib64/python3.6', '/usr/lib/python3.6', '/home/neil/.virtualenvs/default/lib/python3.6/site-pac
kages', '/mnt/work/python/python-tcxparser']
pytest
But I get the same error, even though /mnt/work/python/tcx2gpx where the above directory structure is located, is in the PYTHONPATH.
I have also tried using python -m pytest because, as stated here doing so should automatically include the current directory in syspath. I get the same result though, ModuleNotFoundError.
I also found this article which describes conflicts between a system installed pytest and that within a virtual environment, but firstly I can not uninstall it at the system level because its a required dependency of other packages I have installed in the system, and secondly I get the same error when trying to run the tests in GitLab CI where I don't think there is any other version of pytest installed (I have to explicitly install it as part of the testing stage).
Really stumped on why this isn't working any suggestions or pointers would be very much appreciated.
回答1:
you shouldn't have an __init__.py file at the top of your project -- this is causing pytest to assume that the parent directory is the root of your project
deleting that fixes it for me
