获取精选下拉列表值

Question

我正在尝试使用下一个代码获取下拉框的选定值：

scenario 'USA as default country' do
  expect(page).to have_select('report_country_code', selected: 'United States')
end

此字段的Html是下一个：

<select class="form-control country required" name="report[country_code]" id="report_country_code">
  <option value="US">United States</option>
  ....
  ....
  <option value="ZW">Zimbabwe</option>
</select>

错误如下：

expected to find select box "report_country_code" with "United States" selected but there were no matches. Also found "United States .... Zimbabwe", which matched the selector but not all filters.
