An UnknownObjectException occurs when:

  • Checking the existence (or presence) of an adjacent element (eg followig_sibling, preceding_sibling, etc) and
  • The element does not exist.

For example, given the following page, where the div does not have a following sibling:

<html>
  <body>
    <div id="abc">a</div>
  </body>
</html>

An exception occurs when checking if a following sibling exists:

class MyPage
	include PageObject

	div(:abc, id: 'abc')
end

page = MyPage.new(browser)
page.abc_element.following_sibling.present?
