Several behaviors of :meth:`Parser.addoption <_pytest.config.argparsing.Parser.addoption>` are now
scheduled for removal in pytest 7 (deprecated since pytest 2.4.0):

- ``parser.addoption(..., help=".. %default ..")`` - use ``%(default)s`` instead.
- ``parser.addoption(..., type="int/string/float/complex")`` - use ``type=int`` etc. instead.
