Java - Selenium WebElement isDisplayed（）方法不可用

Question

我正在使用Selenium（2.44.0）進行Java單元測試，並試圖使用WebElement的isDisplayed()方法，但它似乎不是可用。我只能看到isEnabled()和​​方法。

（在Eclipse 錯誤消息： 「isDisplayed（）的方法，是未定義的類型WebElement」）

的pom.xml：

Java代碼：

import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.WebElement; 
import org.openqa.selenium.chrome.ChromeDriver; 
import org.openqa.selenium.support.ui.Select; 

....... 

    WebElement element; 
    int size = driver.findElements(By.xpath("//select[@name='type']")).size(); 
    for (int i = 0; i < size; i++) { 
     element = driver.findElements(By.xpath("//select[@name='type']")).get(i); 
     if (element.isDisplayed()) { 
      select = new Select(element); 
      select.selectByVisibleText("Multi-Level Multi Select"); 
      break; 
     } 
    } 

任何想法我可能會失蹤？

EDIT - 加入充分的pom.xml和蝕錯誤消息，以澄清問題

EDIT（2） - 改變Java代碼來關於實際的（使用的）的Java代碼@Vivek辛格的第一關於異常處理的意見

Answer 1

Selenium commons將WebElement.java引入到沒有isDisplayed（）方法的完全相同的包結構中。所以你的參考很混亂。不要在您的pom.xml中包含硒共享物

Answer 2

這就像@tome所說的。 selenium-common.jar是2.0b1版本。在Selenium 2.0（final）中添加了isDisplayed()。在此之前它位於其他類。所以selenium-common口罩selenium-api這就是你無法編譯的原因。
