Form a little class for reuse of @xverges code on multiple marks/cli options;

@dataclass
class TestsWithMarkSkipper:
    ''' Util to skip tests with mark, unless cli option provided. '''

    test_mark: str
    cli_option_name: str
    cli_option_help: str

    def pytest_addoption_hook(self, parser):
        parser.addoption(
            self.cli_option_name,
            action="store_true",
            default=False,
            help=self.cli_option_help,
        )

    def pytest_collection_modifyitems_hook(self, config, items):
        if not config.getoption(self.cli_option_name):
            self._skip_items_with_mark(items)

    def _skip_items_with_mark(self, items):
        reason = "need {} option to run".format(self.cli_option_name)
        skip_marker = pytest.mark.skip(reason=reason)
        for item in items:
            if self.test_mark in item.keywords:
                item.add_marker(skip_marker)

Usage example (must be put in conftest.py):

slow_skipper = TestsWithMarkSkipper(
    test_mark='slow',
    cli_option_name="--runslow",
    cli_option_help="run slow tests",
)
pytest_addoption = slow_skipper.pytest_addoption_hook
pytest_collection_modifyitems = slow_skipper.pytest_collection_modifyitems_hook
