Java - Selenium WebElement isDisplayed() 方法不可用

Question

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

(Eclipse 中的错误消息:“WebElement 类型的方法 isDisplayed() 未定义”)

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;
        }
    }

知道我可能会错过什么吗？

编辑 - 添加了完整的 pom.xml 和 eclipse 错误消息以澄清问题

编辑 (2) - 将 Java 代码更改为有关 @Vivek Singh 关于异常处理的第一个评论的实际(已使用)Java 代码

Answer 1

Selenium commons 在完全相同的包结构中引入了 WebElement.java，但没有 isDisplayed() 方法。所以你的引用资料被搞乱了。不要在 pom.xml 中包含 selenium-commons
