javascript - 新的 Selenium Web 驱动程序和 Firefox 出现错误。

Question

我正在使用 selenium jar (selenium-server-standalone-3.3.1) 和 Firefox 43.0.4。和 Eclipse 版本:Mars.2 Release (4.5.2)

当我运行以下代码时

import java.util.List;
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.remote.DesiredCapabilities;
public class Links_Count_List {

public static void main(String[] args) {
    System.setProperty("webdriver.gecko.driver","C:\\Users\\daniel\\Desktop\\Selenium\\geckodriver.exe");
    DesiredCapabilities capabilities = DesiredCapabilities.firefox();
    capabilities.setCapability("marionette", true);
    //WebDriver driver = new MarionetteDriver(capabilities); 
    WebDriver driver=new FirefoxDriver();   
    driver.get("http://newtours.demoaut.com/");
    WebElement link=driver.findElement(By.linkText("Home"));
    System.out.println(link.getText());
    //link.click();

    List<WebElement> allLInks=driver.findElements(By.tagName("a"));

    System.out.println("Total number of links are "+allLInks.size());

    for(int i=0;i<allLInks.size();i++){
        System.out.println(allLInks.get(i).getText());
    }


}

}

我收到以下错误。我请求任何人提供帮助。

对我来说这似乎是一个兼容性问题。由于您使用的是最新版本的 Selenium，请尝试更新您的 Firefox 浏览器并重新运行您的脚本。
