我正在尝试验证成功登录后网页上是否存在按钮。我正在使用Webdriver和Python。该按钮位于iFrame中。 这是我的第一个使用页面对象模型框架的webdriver python程序。到目前为止，我认为还不错。
程序成功登录但无法找到iFrame。 我需要一些帮助。
我收到以下错误：
Error

当我在Firefox中检查元素时，HTML如下：
<body style="margin: 0px;">
<iframe id="__gwt_historyFrame" style="position: absolute; width: 0; height: 0; border: 0;" tabindex="-1" src="javascript:''"/>
<iframe id="testCore" src="javascript:''" style="position: absolute; width: 0px; height: 0px; border: medium none;" tabindex="-1"/>
<div style="position: absolute; z-index: -32767; top: -20cm; width: 10cm; height: 10cm; visibility: hidden;" aria-hidden="true"/>
<div class="gwt-TabLayoutPanelTab GEGQEWXCK" style="background-color: rgb(254, 255, 238);">
<div class="gwt-TabLayoutPanelTabInner">
<div class="gwt-HTML">Administration</div>
答案 0 :(得分：2)
您的选择器中有拼写错误。
contentFrame = (By.ID, 'testCore') # capital "C"
应该是
<iframe id="testCore"...
根据你的HTML：
