Java-Selenium WebElement isDisplay（）方法不可用

Question

我正在使用Selenium（2.44.0）进行我的Java单元测试，并且我正在尝试使用WebElement的isDisplay（）方法，但它似乎不可用。我只能看到isEnable（）和isSelected（）方法。

（Eclipse中的错误消息：“方法isDisplay（）未定义为WebElement类型”）

Java代码：

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;
        }
    }

知道我可能错过了什么吗？

编辑-添加完整pom。xml和eclipse错误消息以澄清问题

编辑（2）-将Java代码更改为实际（使用）Java代码，关于@Vivek Singh关于异常处理的第一条评论

Answer 1

这和“汤姆”说的一模一样。硒普通。jar是版本2.0b1 isDisplayed（）。在此之前，它被定位于其他类别。因此，selenium common掩码就是您无法编译的原因。

Answer 2

Selenium commons引入了WebElement。java的包结构完全相同，没有isDisplayed（）方法。所以你的参考资料被搞砸了。不要在pom中加入硒公地。xml
