从 Firefox 4 升级到 5 后，Selenium 2 Webdriver 无法通过 xpath 找到元素答案

【问题描述】：

我正在尝试编写一个测试，该测试将单击描述框并输入快速描述。在 Firefox 4 中使用 Selenium 2.0 时，我使用的是代码：

      WebElement venueDescription = driver.findElement(By.xpath("//iframe[contains(@id,'Frame')]"));

   venueDescription.sendKeys("This is a description for the Venue");

为此。但是，在升级到 firefox 5 和 Selenium 2.1 后，我收到“无法定位元素”错误。这是代码的副本。第一个和第三个 textarea 是隐藏的，所以我使用 contains() 来选择第二个 textarea。这在更新之前工作正常。

【问题讨论】：

如果您想回答这个问题，我建议您将示例 HTML 缩减为更简单的条件。

标签： firefox testing xpath selenium selenium-webdriver

【解决方案1】：

在与 iFrame 交互之前，您是否尝试过先切换到 iFrame？

在我测试的网站上，所有内容都嵌入在 iFrame 中，在我可以访问其中的任何元素之前，我首先必须切换到它们，如下所示：

driver.switchTo().defaultContent();
driver.switchTo().frame(driver.findElement(By.xpath("//iFrame[@id='Frame']")));
