Answer 1

に問題を見つけることができないが一緒に表示されます。HTMLの画像から

browser.div(:class => "select2-drop select2-display-none select2-with-searchbox select2-drop-active") 

、これはli要素を含むdivではありません。要素を含むのは兄弟divです。そして、結果ビーイングを終了

browser.div(:id => "select2-drop") 

：それはIDを持っているとして、あなたは経由して、それを見つけることができ、共有HTMLから

li_count_in_ul9 = browser.div(:id => "select2-drop").ul(:class => "select2-results").lis(:class => "select2-results-dept-0 select2-result select2-result-selectable") 

、これは、指定した上かもしれません。あなたは単純に次のことを行うことができます：

li_count_in_ul9 = browser.div(:id => "select2-drop").lis(:class => "select2-result-selectable")
