DNS software test harness
=========================
The tests depend on cwrap's `socket_wrapper`_, libfaketime_ and Python.
The libfaketime is included in ``contrib/libfaketime`` as it depends on rather latest version of it,
it is automatically synchronised with ``make``.
Execute the tests by:
.. code-block:: bash
$ make DAEMON=/usr/local/bin/kresd
.. todo:: Writing tests.
.. _cmocka: https://cmocka.org/
.. _`socket_wrapper`: https://cwrap.org/socket_wrapper.html
.. _libfaketime: https://cwrap.org/socket_wrapper.html
