the test for input type=checkebox role=... returns the correct 4 valid roles.

however the info returned for required states is inaccurate

on a input type=checkbox the menuitemcheckbox or switch roles shouldn't require aria-checked, as they can rely on the input's default checked attribute / state.

also, if using role=button on a checkbox, there needs to be a required aria-pressed state, otherwise role=button should be flagged as an invalid role.

edit:

a similar issue exists for input type=radio with role=menuitemradio. the input's default checked attribute / state can be used rather than aria-checked, so that shouldn't throw a required state error
