"""
The following code was taken from:

    https://github.com/pytest-dev/pytest/issues/568#issuecomment-216569420

to resolve a bug with using pytest.mark.skip(). Once the bug is resolved in
pytest this file can be removed along with all the wrapper mark_class()
references in the other test files.
