Q: How to add a custom flag to pytest, using the short form I was following this answer about how to add custom arguments to pytest in order to skip tests with the custom marker. It works, but I can't seem to customize it to use a short version of the flag.
I've added these functions to my conftest.py:
def pytest_addoption(parser):
    parser.addoption("-fs", dest='full_suite', action="store_true",
        help="Run the full test suite. Includes tests marked with the mark.full_suite flag")


def pytest_runtest_setup(item):
    if 'full_suite' in item.keywords and not item.config.getoption("-fs"):
        pytest.skip("You need the -fs option to run this test")

And then I write this test:
@pytest.mark.full_suite
def test_something():
    assert True

If I use the long option, for example, --fs, rather than -fs, it will work, and dest will be assigned to fs. With the short option, I'm apparently required to supply the dest keyword. But I did this, I added dest='full_suite. Despite that, I get this error:
....
 self.option_id = str(option)
  File "/home/jokea/Carbonspace/cs-landsat-sentinel/.python3.8_env/lib/python3.8/site-packages/_pytest/config/argparsing.py", line 326, in __repr__
    args += ["dest: " + repr(self.dest)]
AttributeError: 'Argument' object has no attribute 'dest'

What am I missing?
