Testing/development tips

After git clone or wget && tar, we will get a directory called cffi or cffi-x.x.x. We call it repo-directory. To run tests under CPython, run the following in the repo-directory:

pip install pytest
pip install -e .  # editable install of CFFI for local development
pytest src/c/ testing/
