当我尝试使用webDriver搜索一个或多个元素时,它什么都不返回。 操作系统:Ubuntu 14.04,FrameWork:Intellij Idea,语言:Java。
我有这些陈述:
WebDriver myWebDriver = new FirefoxDriver();
String myClass = "hid";
然后转到:
myWebDriver.navigate().to("https://www.youtube.com/");
所有这些都有效。但是当我宣布:
private List <WebElement> myElements = new ArrayList<WebElement>();
然后按原样访问myElements:
myElements = myWebDriver.findElements(By.className(myClass));
myElements为null,因为findElements似乎失败,以及findElement(webElement)(后者,我将List更改为常规WebElement)。这在以前有效。
以及所有代码:
package com.search.mywork;
import org.junit.Test;
import org.openqa.selenium.*;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import java.util.ArrayList;
import java.util.List;
import java.util.Set;

答案 0 :(得分:1)
这是你的问题:
private void logIn(){
//Create Driver and log in
// myWebDriver is a Class field already
// Remove WebDriver declaracion
this.myWebDriver = new FirefoxDriver();
myWebDriver.navigate().to("https://www.youtube.com/");
}
您正在创建一个新的WebDriver
,因此当您在findElements
函数中使用它时,它未正确初始化。
希望这有帮助!
