Capybara，选择复选框类型标签，未显示复选框

Question

代码看起来像这样：

    <span ng-switch-when="boolGroup" class="ng-scope">
    <label class="col-sm-6 control-label">
                                   Available tabs:
                            </label>
    <span ng-repeat="key in detail.keys" class="something ng-scope">
    <input type="checkbox" id="TAB_1" style="display: none;" class="ng-valid ng-dirty">
    <label ng_class="something something..." for="TAB_1" class="ng-binding auth-selected-editable">
        Example
</label>
    </span> ... </span>

我需要选择标签：“示例”，它是复选框类型，但不显示复选框。所以基本上它显示为选择框，但在HTML代码中它是复选框。

Capybara说：Unable to find checkbox "Tab_1" <Capybara::ElementNotFound>
