CI seems broken at the moment:

    ==================================== ERRORS ====================================
    ____________________ ERROR collecting tests/test_default.py ____________________
    tests/test_default.py:6: in <module>
        os.environ['MOLECULE_INVENTORY_FILE']).get_hosts('all')
    /home/travis/virtualenv/python3.6.3/lib/python3.6/site-packages/testinfra/utils/ansible_runner.py:153: in __init__
        self.cli.options = self.cli.base_parser(
    E   AttributeError: 'PlaybookCLI' object has no attribute 'base_parser'
    !!!!!!!!!!!!!!!!!!! Interrupted: 1 errors during collection !!!!!!!!!!!!!!!!!!!!
    =========================== 1 error in 0.54 seconds ============================
An error occurred during the test sequence action: 'verify'. Cleaning up.

This seems to be related to ansible/molecule#2083 which is already closed.
