Yes, I think I arrived at a similar place, except
1) using "python3 setup.py --build-lib build/stage" to build. I'm not
sure which is better, I think it will depend a bit on when we try to get
out of tree builds working. It is a bit nicer to have the build output
out of tree, but then I have to copy the tests.
2) instead of changing PYTHONPATH, use "python3 -m pytest", which picks
up the module in the current directory.

The LD_LIBRARY_PATH is already set by the test harness, as is PATH (to
find notmuch). It looks like your function notmuch is not respecting
PATH (see attached log). if I hack something like
diff --git a/bindings/python-cffi/tests/conftest.py b/bindings/python-cffi/tests/conftest.py
index 1b7bbc35..ac17397c 100644
--- a/bindings/python-cffi/tests/conftest.py

cfg_fname = maildir.path / 'notmuch-config'
- cmd = ['notmuch'] + list(args)

print('Invoking: {}'.format(' '.join(cmd)))
proc = subprocess.run(cmd,
then the tests pass, but this is obviously not a good solution.
