So I can run the tests using `make` and `cd tests;
./T-391-pytest-cffi.sh`.  I can also run the tests still individually
using something like:

make
set PATH (pwd) $PATH  # I use fish
pushd bindings/python-cffi
pew workon notmuch  # how I manage python virtualenvs
pip install -e .
pip install pytest pytest-cov
pytest test/test_base.py

And all works.  I added a little function to the conftest.py to show
which notmuch it's testing with:

def pytest_report_header():
    vers = subprocess.run(['notmuch', '--version'],
                          capture_output=True, text=True)
    which = subprocess.run(['which', 'notmuch'],
                           capture_output=True, text=True)
    return ['{} ({})'.format(vers.stdout.strip(), which.stdout.strip())]

Maybe you find that useful too.

Anyway, this looks good.  Would you like some changes, e.g. the rename
to notmuch2 or so as patches?  What's the next step.



Kind of unrelated, but in my attempt to run the full notmuch test suite
(cd tests; make test) I somehow ended up with lots of weird tags in my
notmuch database and made the emacs UI pretty horrible - though it seems
I haven't lost any email.  I'm sure that was my fault somehow even
though I was just trying to follow the readme.  But if anyone has any
hints how to recover from this that could save me some time :)

Cheers,
Floris
