当我尝试使用webdriver搜索一个或多个元素时，它不会返回任何内容。
操作系统：ubuntu 14.04，框架：intellij idea，语言：java。
我有以下声明：
WebDriver myWebDriver = new FirefoxDriver();
String myClass = "hid";
然后转到：
myWebDriver.navigate().to("https://www.youtube.com/");
所有这些都管用。但当我宣布：
private List <WebElement> myElements = new ArrayList<WebElement>();
然后像这样接触髓鞘：
myElements = myWebDriver.findElements(By.className(myClass));
myelements是空的，因为findelements似乎失败了，还有findelement（webelement）（对于后者，我将列表更改为常规webelement）。这在以前是有效的。
这里是所有代码：
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;

最佳答案
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，它没有正确初始化。希望这有帮助！
