Question

我只是想尝试执行基本的硒测试。没什么特别的，只是为了确保它有效。但是抛出异常。我能做错什么？

当然我使用：java -jar selenium-server-standalone-2.24.1.jar

启动了服务器

import static org.junit.Assert.fail;

import java.util.concurrent.TimeUnit;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.NoSuchElementException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Selenium {
    private WebDriver driver;
    private String baseUrl;
    private StringBuffer verificationErrors = new StringBuffer();

    @Before
    public void setUp() throws Exception {
        driver = new FirefoxDriver();
        baseUrl = "http://www.google.de/";
        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
    }

    @Test
    public void testSeleniumWeb() throws Exception {
    //empty just for testing
    }
}

抛出：

这与您的代码无关。你有一个类路径问题。有些类依赖于ElementNode2的不同版本，而不是类路径中最先找到的版本。

如果查看jarfinder，您可以看到在JDK 1.4之后，此类包含在Java运行时（rt.jar）中。

我怀疑您使用的是旧版本的JDK而不是编译WebDriver的版本。 WebDriver需要JDK 1.6 +。

使用Selenium WebDriver进行简单的测试设置失败
