java - 我想知道运行 java selenium 代码所需的版本

Question

当我运行一个简单的 java selenium 代码来启动 Facebook 应用程序时，我收到错误“等待驱动程序服务器启动超时”。

我的代码:

package newpackage;
import org.openqa.selenium.*;
import org.openqa.selenium.chrome.ChromeDriver;


public class PractAuto {
    public static void main(String[] args) throws InterruptedException {
          System.setProperty("webdriver.chrome.driver", "C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");
          WebDriver driver = new ChromeDriver();
          driver.manage().window().maximize();
          driver.get("https://www.facebook.com/login/");
          Thread.sleep(5000);
          driver.findElement(By.name("email")).sendKeys("arunkumar3625@gmail.com");
          driver.findElement(By.name("pass")).sendKeys("Password");
          driver.findElement(By.id("loginbutton")).click();
          driver.findElement(By.name("mercurymessages")).click();
          driver.findElement(By.cssSelector("a[href*='https://www.facebook.com/messages/conversation-8148306']")).click();

    }

Chrome 浏览器已成功打开，但出现上述错误。

Answer 1

您可以通过此链接查看 selenium 和 webdrivers 的最新版本 https://www.seleniumhq.org/download/

此外，您还可以分享您的代码，以便更好地了解错误原因。

检查代码后，您将驱动程序的属性设置为错误的路径。属性 webdriver.chrome.driver 应该是 chrome 驱动程序而不是 chrome 可执行文件。
