java - Selenium 网络驱动程序 : <WebElement> Iterator cannot be resolved to a type

Question

我的问题简述:

现在通过我的 selenium 网络驱动程序，我正在测试列表框中的元素列表，在使用以下代码时出现错误

测试配置:

• 火狐浏览器
• eclipse 靛蓝
• Selenium 网络驱动程序 2

我测试的场景:

1. 打开网站
2. 选择并显示列表框项目
3. 写到控制台

我的错误:

java.lang.Error: Unresolved compilation problems: The type List is not generic; it cannot be parameterized with arguments Iterator cannot be resolved to a type

我的代码:

        //To go through the list, we can use an Iterator. 
        //Iterator should be of the same type as the List
        //which is WebElement in this case.

        Iterator<WebElement> it = allOptions.iterator();

        //a next WebElement [hasNext() is true]

        } catch (NoAlertPresentException e) {
            return false;
        }

    private String closeAlertAndGetItsText() {
        try {

            String alertText = alert.getText();
            if (acceptNextAlert) {
                alert.accept();
            } else {
                alert.dismiss();
            }
            return alertText;
        } finally {
            acceptNextAlert = true;
        }
    }
}

我不知道哪里错了，指导我哪里错了

参见 org.openqa.jetty.html.List 的 javadoc:http://www.jarvana.com/jarvana/view/org/seleniumhq/selenium/selenium-server/2.0b1/selenium-server-2.0b1-javadoc.jar!/org/openqa/jetty/html/List.html

和 java.util.List 之一:http://docs.oracle.com/javase/7/docs/api/java/util/List.html

您使用的不支持泛型(如错误所述)。

您的问题似乎是以下导入:

import org.openqa.jetty.html.List;

尝试将其替换为:

import java.util.List;
