tl;dr: The issue in the test suite is that there is no test suite.

setuptools is trying to find the tests declared in setup.py:

EXTRA_KWARGS = dict(
    install_requires = ['setuptools'],
    include_package_data = True,
    test_suite = "tests",                        <-- here
    zip_safe = True,
    )

According to <https://setuptools.readthedocs.io/en/latest/setuptools.html>,
setting test_suite like this means: you can import the 'tests' module and
the result is a package or module containing unittest.TestCase subclasses.

However, the tests/ directory (as of python-dendropy_4.4.0-1) does not
contain any Python code at all, only some test data in tests/data/,
so this assertion doesn't seem to be true.

If you look at the buildd logs you'll see that dh_auto_test fails in
Python 2 as well, but the failure is ignored:

The failure mode is different in Python 3 because in Python 2, a directory
that does not contain __init__.py cannot be imported as a package (hence
"No module named tests"), but in Python 3, it can. From the backtrace
you gave, presumably the resulting module object has
tests.__file__ == None, which breaks assumptions made by setuptools.

I would suggest removing the test_suite parameter for now, and asking
your upstream to include the test suite in future source code releases.
