C# Protractor - 在另一个元素中查找元素

Question

我正在用 HTML 测试一个 AngularJS 应用程序，看起来像这样:

<div class="ng-scope" ng-repeat="something in section.questions">
...
</div>
<div class="ng-scope" ng-repeat="something in section.questions">
...
</div>
<div class="ng-scope" ng-repeat="something in section.questions">
            <div ng-switch="something.visible">
                <div id="Ins_Othersumarea" class="content-detail-wrap ng-scope ng-isolate-scope" ng-switch-when="true" highlight="something.code == global.highlightedQuestionCode" highlightedcode="global.highlightedQuestionCode" ng-dblclick="logObject(something)">                         
                    <div ng-class="{divider: showDivider(section, $index)}">                                                                                     
                        <div ng-switch="something.type" class="content-detail-section">                                                                 
                            <div class="ng-scope" ng-switch-when="TRIGGER_YES">
                                <ng-include class="ng-scope" src="getFragment('yes-no-fragment.html')" ng-if="!global.interview.isGroup" ng-init="baseQuestion = something">
                             <div class="row ng-scope">
                                 <div class="col-sm-6" ng-switch="baseQuestion.answerValue == undefined &amp;&amp; !global.readonly">
                                     <div class="content-detail-right ng-scope" ng-switch-when="true">
                                         <div class="row">
                                             <div class="col-xs-6">
                                                 <button type="button" id="yes_Ins_Other  sum area" class="btn-base-question-triggers ng-binding" ng-click="answerbaseQuestion(baseQuestion, true)" tabindex="1" setfocus="Ins_Other  sum area">Yes</button>
                                             </div>
                                             <div class="col-xs-6">
                                                 <button type="button" id="no_Ins_Other  sum area" class="btn-base-question-triggers ng-binding" ng-click="answerbaseQuestion(baseQuestion, false)" tabindex="1">No </button>
                                             </div>
                                         </div>
                                     </div>
                                 </div>
                             </div>
...

我正在尝试根据转发器 Div 文本内容查找嵌套的是/否按钮。

我可以通过 - 找到正确的 ng-repeat 元素

var repeatElement = NgDriver.FindElements(NgBy.Repeater("something in section.questions")).First(x => x.Text.Contains("Some Text"));

但是我想不出一种方法来捕获适当的是/否按钮..

我试过了-

repeatElement.FindElement(By.XPath("//button[contains(.,'Yes')]"))

但这会返回第一个"is"按钮在页面上(而不是像我预期的那样在 ng-repeat Div 中)。

1. 为什么？？
2. 我怎样才能完成我想做的事情？

Answer 1

repeatElement.FindElement(By.XPath("//button[contains(.,'Yes')]"))

这几乎是正确的，除了 XPath 表达式必须以点开头是上下文/repeatElement 特定的:

repeatElement.FindElement(By.XPath(".//button[contains(.,'Yes')]"))
