The new test runner is needed as Travis does not know python2 and python3.
(BTW I have the same problem on my computer, so I cannot use the previous
approach with the Makefile without modifications on my system.)
The tests in grammar/test_grammar.py are not run because I was not able to find
out how to run make in the grammar directory before installing the package.
See https://tox.readthedocs.io for documentation on tox and
https://docs.pytest.org for documentation on pytest. (These tools are widely
used in the Python community and would make it easier for contributors to run
the tests.)
I had to fix two tests to be able to run them successfully.
