I see some major changes in specs e.g. [disabled] -> [disabled=true], but I trust your judgement that this is correct.

This is a correction to the following comment. https://github.com/rubocop/rubocop-rspec/pull/1481#discussion_r1035856116

CSS selector [visible] means the element has an attribute named visible (e.g. ), NOT "the element is actually visible". CSS does not have :visible pseudo-class --- it's a jQuery's extension. And also, [focused] means the element has an attribute named focused, NOT "the element is now focused". :focus pseudo-class should be used instead.

Therefore, we do not believe that [disabled] can be replaced by a Specific actions/finders/matcher.

Merge at will, @ydah !
