在selenium中创建测试脚本时，我遇到以下错误

Question

package javaapplication3;
import java.lang.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.WebDriver;
/**
 *
 * @author kipl74
 */
public class JavaApplication3 {

    /**
     * @param args the command line arguments
     */
    static WebDriver driver = new FirefoxDriver();
    public static void main(String[] args) {
        // TODO code application logic here
        String baseurl="www.google.com";

        driver.get(baseurl);

    }
}

当我运行这段代码时，我得到了以下错误。如何解决？

Answer 1

请检查您的调用方法以打开浏览器。我相信您已经编写了这样的代码：

driver.get("Url"); //Incorrect Code

正确的应该是这样：

driver.get(Url);// Correct Code

Answer 2

方法get需要协议作为URL的一部分。

更改：

String baseurl = "www.google.com";

致：

String baseurl = "http://www.google.com";
