Selenium 2 Webdriver無法找到xpath從Firefox 4升級到5之後的元素

Question

我正在嘗試編寫一個測試，它將點擊一個描述框並鍵入一個快速描述。在Firefox 4中使用Selenium 2.0時，我使用的代碼是：

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

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

要做到這一點。但是，升級到Firefox 5和Selenium 2.1後，我收到「無法定位元素」錯誤。 這裏是代碼的副本。 第一個和第三個textarea被隱藏，所以我使用contains（）來選擇第二個textarea。這是工作正常，直到更新。

Answer 1

您是否嘗試過在與之交互之前先切換到iFrame？

在網站上我測試，一切都被嵌入iFrame中之前，我可以去任何他們的元素，我必須先切換到他們，就像這樣：

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