java - 获取错误 "java.lang.NoClassDefFoundError: com/gargoylesoftware/htmlunit/html/HtmlElement"

Question

我正在使用 selenium webdriver 进行测试我编写了代码:

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.MarionetteDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
//import org.openqa.selenium.firefox.FirefoxProfile;
import org.testng.Assert;
import org.testng.annotations.AfterTest;
//import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;


public class sample_google
{

	WebDriver driver;


    @BeforeTest

    public  void setUp(){

       // FirefoxProfile profile = new FirefoxProfile();
    	//System.setProperty("webdriver.gecko.driver", "D:\\ashwini\\geckodriver.exe");
    	
//		  driver= new MarionetteDriver();
    	 driver = new HtmlUnitDriver();

	    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    }


    @Test

    public void testLoadingFirstPage() throws Exception{

        driver.get("https://www.google.com/");
        WebElement searchBox = driver.findElement(By.name("q"));
        searchBox.sendKeys("fast cars");
        searchBox.submit();
        System.out.println("Page title : " + driver.getTitle());
        WebElement resultCount = driver.findElement(By.id("resultStats"));
        System.out.println("Result Count : " + resultCount.getText());
       

    }
    @AfterTest
	  public void teardown()
	  {
		  //driver.quit();
	  }

    
}

但是我得到了输出

我在代码中包含了 selenium-htmlunit-driver-2.46.0.jar 的 jar。仍然收到错误。所以请检查是什么问题。

提前致谢

我在库中单独包含了 selenium-htmlunit-driver-2.46.0.jar 的 jar。还是报错

Answer 1

将以下依赖项添加到您的 pom.xml 文件中，它应该可以正常工作

<groupId>org.seleniumhq.selenium</groupId>
<artifactId>htmlunit-driver</artifactId>
<version>2.20</version>
</dependency>

从 2.53 开始，这不再与 webdriver 一起提供
