Question

我是Selenium的新手，从我在标识元素时指定绝对路径可以看出。我写了一个简单的代码来打开gmail登录页面 `

package SeleniumScripts;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;

public class LogintoGmail {

    public static void main(String[] args) {

        System.setProperty("webdriver.gecko.driver", "D:\\Selenium\\geckodriver-v0.19.1-win64\\geckodriver.exe");`enter code here`
    //  System.setProperty("webdriver.ie.driver", "D:\\Selenium\\IEDriverServer_x64_3.8.0\\IEDriverServer.exe");
        WebDriver driver=new FirefoxDriver();
    //  WebDriver driver=new InternetExplorerDriver();  
        driver.get("http://www.gmail.com/");
        driver.manage().window().maximize();
        driver.findElement(By.xpath("/html/body/div[1]/div/div[2]/div/div[2]/form/div[2]/div/div/div/ul[1]/li[1]/div/div[2]/p[2]")).click();
        driver.findElement(By.xpath("/html/body/div[1]/div/div[2]/div/div[2]/div/div/div[2]/div/div[1]/div/form/content/section/div/content/div[1]/div/div[1]/div/div[1]/input")).sendKeys("12!harley");
        String apptitle=driver.getTitle();
        System.out.println(apptitle);

    }

}

` 运行代码时，Firefox打开，然后打开URL，然后关闭。我在执行过程中遇到以下错误：

请注意，一周前运行良好，但现在出现错误。

    package SeleniumScripts;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;

public class LogintoGmail {
    public static void main(String[] args) {

        System.setProperty("webdriver.gecko.driver", "D:\\Selenium\\geckodriver-v0.19.1-win64\\geckodriver.exe");
        WebDriver driver = new FirefoxDriver();


        driver.get("http://www.gmail.com/");
        driver.manage().window().maximize();
        driver.findElement(By.xpath("X/PATH")).click();
        driver.findElement(By.xpath("X/PATH")).sendKeys("12!harley");
        String apptitle = driver.getTitle();
        System.out.println(apptitle);

尝试复制我所做的事情，该代码虽然非常混乱，但只是正确，只是在声明firefox驱动程序时没有空格，在两个实例中您没有适当的间距，并且确实使差异。

当代码错误时，很多时候驱动程序会强制浏览器打开，但会保留URL为空或null值，而不会继续测试。

如果我是你，我将首先打开页面并在脚本之上构建。

Firefox浏览器没有打开指定的URL而关闭
