Failing tests for python 3.12

[blotero]

When running contribution tests for python 3.12 env:

tox -e py312

I get the following output:

py312: install_package> python -I -m pip install --force-reinstall --no-deps /home/brandon/remotes/pytest-mock/.tox/.tmp/package/3/pytest-mock-3.12.1.dev10+g3d48ff9.tar.gz

I'm running this in Debian 12 inside a venv with python 3.12.1, and by the way, also get a similar failure when running pre-commit install:

Is there any other tool required to be installed in the machine and therefore not documented in contributing docs or is this a bug?

The stacktrace you posted points at inside coverage, so this isn't really anything related to pytest-mock.

It's neither really - you seem to have a broken Python missing the built-in sqlite3 module. Given the /usr/local/lib path, I'm assuming you built it yourself, and it was built without sqlite3 support. A quick search for the error message will lead you to possible causes, the most probably being that you didn't install libsqlite3-dev before building Python.
