This post compares the pytest results of dateutil to its nuitka-built .whl counterpart.

Dateutil standalone test have already been covered. Manual testing is now done to compare the pytest results of a nuitka wheel built using python setup.py bdist_nuitka to the regular pytest of the dateutil package. Testing is done to ensure that nuitka is building the wheel correctly. If the pytests pass/fail in the same way, that means Nuitka built the wheel properly. Else if the tests differ, then something is wrong. Virtualenv is used to create a clean environment with no outside pollution.

The pytest results were very similar:

Regular pytests: ============= 1977 passed, 76 skipped, 21 xfailed in 7.99 seconds =============
Nuitka wheel pytests: ============= 1976 passed, 76 skipped, 21 xfailed in 7.89 seconds =============

Steps to Reproduce 

Clone dateutil and nuitka into a new folder
Inside the dateutil folder, issue python -m pip install -r requirements-dev.txt to install its requirements.
Issue python -m pytest --disable-warnings , this runs the regular pytest for dateutil.
Change into the nuitka folder and issue python setup.py develop .
Change back into dateutil and issue python setup.py bdist_nuitka to build the dateutil wheel using nuitka. The newly built wheel should be found in the dist folder.
Use pip to uninstall the existing dateutil, then issue python -m pip install followed by the newly built .whl filename.
Issue python -m pytest --disable-warnings , this runs the nuitka-built wheel pytest for dateutil.
